The waterproofing membrane is not pierced or interrupted in any way and the paving slabs can be taken up at any time if the deck beneath needs to be inspected. The weight of the slab holds the whole system in place. It is a much faster, cleaner and easier way to lay paving onto concrete decks than by bedding them into mortar. 17MM HIGH PLASTIC SUPPORT PADS The standard, most commonly used support pad Wallbarn offers is the 17mm high plastic support pad. The plastic ring shaped pad is a simple design, but very hard wearing and tough. It is easy to store, handle and install. The pad is placed beneath the paving slab so that the corner of the slab rests on a segment of the support and is held into place by the right-angled positioning lugs. Four corners will sit onto one support pad and the whole system is held securely in place by the weight of the slab. Wallbarn plastic support pads are injection moulded high density polypropylene made from recycled plastic. They are circular in shape with a hollow middle and a smooth, flat underside. The upper side has reinforcing bars around the face of the circle to help support the weight of the slab. The pad has four positioning lugs - small bars emerging from the face of the support in a cross formation. These give a 5mm wide gap between each paving slab, allowing water to drain effectively in between each slab to the deck beneath. This means there is no standing water on top of the slabs and the rainwater can be channelled and collected efficiently. The lugs also ensure clear, consistent spacing between each slab, which gives uniform, straight paving line. This creates an attractive, superior finish to paved areas. There are a series of small holes around the edge of the support pad for drainage, meaning no water will collect either within the support itself or in the central hole. This is important as standing water can attract insects or lead to bad odours. The plastic supports are made in four quadrants joined together with a small link. They can be easily snapped into segments of a half or quarter to support paving slabs up to edges or around corners. This eliminates wasting a whole support for one small section, a major advantage over other support pads on the market. It will also give a tidier finish to details. SUPPORT PADS FOR PAVING WALLBARN SUPPORT PADS ARE DESIGNED TO SUSPEND PAVING SLABS OFF THE WATERPROOFED DECK. THIS ALLOWS WATER TO DRAIN BETWEEN AND BENEATH THE SLABS PREVENTING LOCALISED FLOODING ON THE TERRACE. 5 14MM HIGH PLASTIC SUPPORT PADS Wallbarn can supply a polypropylene support pad which is 14mm high. Manufactured in exactly the same way as the 17mm support and made from the same recycled material, these supports share the same properties but are slightly thinner. This gives installers a slightly more cost effective option when laying suspended paving. Plastic support pads are truly adaptable, and a large range of coverings can be placed onto them. They can be used to suspend Wallbarn hardwood timber tiles as well as concrete paving slabs. A natural, luxurious finish can be created much easier than by installing long plank decking and is more cost effective. As well as the standard concrete pressed slabs common on many public walkways, these pads are ideal for use with natural stone and promenade tiles. This can produce a truly high- class finish to roof decks and terraces. Wallbarn recommends that slabs or tiles are at least 30mm thick. Users must be sure that the tile is strong enough to be suspended, and is heavy enough to remain stable once in situ. Users should contact the slab manufacturer for clarification. Where applicators are laying thinner tiles or very large slabs, it is very easy to snap off all the positioning lugs to create a smooth ring and place the pad underneath the centre of the slab for extra support. If the slabs are laid in a complicated pattern, a support can have some or all of the lugs removed to create a T junction to support three slabs in a staggered formation. For additional height, applicators can stack both the 17mm and 14mm plastic supports one on top of another. The lugs will be housed within the drainage cavity of the pad above, and the corner of the slab laid on top as normal. However, Wallbarn recommends that a maximum of two pads are stacked up. A larger number of pads stacked up can lead to instability, so Adjustable Support Pads should be chosen where greater heights are required. For both 17mm and 14mm high plastic support pads, any minor differences in the level of the paving slab can be arrested by fitting plastic levelling shims onto the upper side of the disc. They are available 1mm, 2mm and 3mm thick. Further details can be found on page 8. PLASTIC SUPPORT PADS ARE AVAILABLE IN DIFFERENT HEIGHTS TO GIVE GREATER FLEXIBILITY TO DESIGNERS AND APPLICATORS.

The rubber is a much tougher, more durable material, and the disc is a solid ring, so can tolerate much higher weight than the plastic pads. Being made from rubber, the pad is much softer and more flexible than polypropylene. This makes the pad ideal for laying onto more delicate surfaces such as insulation, mastic asphalt and single ply. The material is flexible and has a great deal of elasticity. The pad is also manufactured with a curved underside at the edges, which means there is less risk of the pad digging into the deck beneath. The soft profile of the rubber pad also makes it ideal for use with very hard surfaces, and it has been laid successfully directly onto surfaces such as fibreglass and glass without any risk of causing scratches or damage. The rubber compound also helps prevent the pad from slipping on the sub-surface. The pad is manufactured with four lugs on the upper side which keep the slabs in position. The lugs are 5mm wide, which ensures a good level of drainage between each slab and helps maintain a straight paving line along the area. Again there is no mechanical fixing of the slabs or pads, and applicators do not have to point between the slabs. This saves a great deal of time when laying flags onto a large area. As the slabs are not bedded into mortar, significant savings are made in both labour and extra weight on the roof. It is also a far less messy way to install paving. The pads can either be cut with a sharp knife if installers wish to butt the slabs right up to the wall or upstand, or a small border of washed pebbles can be laid around the perimeter as a border. WALLBARN OFFERS SUPPORT PADS MANUFACTURED FROM RUBBER FOR APPLICATORS WHO DESIRE A SOFTER MATERIAL TO INTERFACE WITH THE DECK BENEATH. 7 5MM RUBBER DISCS Where applicators have very restricted height thresholds, Wallbarn can offer a solution in the form of 5mm thick rubber discs laid in conjunction with cross spacers. The solid circular discs are made from PVC with a smooth finish. Separation of each slab is achieved with a loose laid cross spacer. These are available in various thicknesses and further details are given below. 3-8MM WEDGE SHAPED RUBBER DISCS Wedge shaped discs are also available. They are similar to the 5mm discs but wedge shaped instead of being flat. They slope from a thickness of 8mm at the highest down to 3mm. On areas where there is only a very small threshold, it is possible to use two of these wedge shaped discs together to act as an alternative adjustable pad. More a shock absorber or membrane protection than an actual support, they can be slid towards or away from each other to create different thicknesses, achieving a range from 3mm (where one has been used on its own, up to 11mm, where two have been stacked on top of each other completely). A better use for these items are as slope correctors beneath fixed height support pads. Simply placed onto the deck with a plastic or rubber ring loose laid on top without fixings, they can take out the fall in the deck to ensure that the support pad is completely vertical and straight, and the paving does not tilt in any way. CROSS SPACERS The discs described above are all flat pads without integrated separation lugs. Where they are being used for paving, it is advisable that loose laid cross spacers are placed on the centre of the disc to achieve the accurate, straight paving line. These polypropylene two-part pieces are slotted together to create a small cross shape, which can be fitted into the junction between four paving slabs to ensure they remain straight and in place. Therefore, regular paving can still be achieved even when using flat discs. The cross spacers are available 3mm, 4mm and 5mm thick. All of these sizes will ensure adequate drainage, the gaps between the paving slabs depends more on the wishes of the designer.

This can happen where the thickness of the actual paving slab alters slightly from one flag to another, where the deck underneath changes or where an unexpected door threshold occurs, for example. These minor changes can be addressed with the use of levelling shims. Levelling shims have been designed to fit on top of all fixed height support pads and will make up those small differences in the level. To avoid one of the slabs rocking, applicators can simply hang a levelling shim onto the support pad to make up the difference. 1mm & 2mm shims 3mm shims Shims are available 1mm, 2mm and 3mm thick. They are loose fitted and held in place by the positioning lugs. The 3mm thick shim has a slightly different shape to the 1mm and 2mm shims, but all three are suitable for all of the fixed height supports. The shims will overhang the rubber ring slightly, but this is no issue. The weight of the slab will ensure that the whole system is held in place properly. All shims can be snapped apart into a half shape or into quarters where only one corner needs extra support. This is often required where just one of the flags becomes unsteady and needs bringing up to the level of the others. Multiple shims can be stacked onto a support pad, but care should be taken that the lug does not become engulfed as this will affect the paving guide and compromise straightness. There needs to be enough of the lug showing for the slab to butt up to. RUBBER ACOUSTIC / ANTI-SHOCK SHIMS These shims are styled in the same design as the standard plastic 3mm shim, but are made from PVC instead of plastic. They are 2.5mm thick and can be placed onto both fixed height support pads, ASP adjustable supports and TD timber decking supports. They act as an effective vibration or sound control layer. They can deaden the sound of pedestrian traffic over tiles or timber decking (very useful when terraces are being installed on top of dwellings below) and give extra protection by preventing the risk of vibration damaging the tiles over time. LEVELLING SHIMS IN A NUMBER OF DIFFERENT SIZES ARE AVAILABLE TO USE IN CONJUNCTION WITH BOTH PLASTIC AND RUBBER SUPPORT PADS. 9 ADJUSTABLE SUPPORT PADS FOR PAVING Best practice for roof and terrace design is to ensure the deck is built to a fall to allow proper drainage. Where a very high clearance is required, and to create the highest level finishes the best way to arrest the continual change to the deck level is to use adjustable support pads. Unlike fixed height supports, which can only be altered in height by adding shims, changes in level that are irregular, very large or continual can easily be accommodated using ASP adjustable supports for paving. These adjustable supports create a completely flat upper surface on roofs built-to-falls in the safest, most efficient way. The robust supports are manufactured from injection moulded polypropylene and can tolerate loads of 400kg per unit. They are made from virgin material. Wallbarn has to use virgin material for all adjustable supports to ensure that the weight tolerance and strength is consistent. Unfortunately the consistency of the material cannot be guaranteed when using recycled plastic as the sources and quality cannot always be traced and measured. Beware claims of strength performance on moving parts when using recycled plastic. As this is a suspended system, there is no risk of the delicate waterproofing membrane beneath being pierced or damaged. The weight of the slabs is spread through the base plates. If the deck ever needs to be inspected, the system can be taken up easily. The cavity also presents opportunities to hide unsightly objects, such as water pipes, electricity cables, drainage outlets and manholes beneath the paving slabs. They can be used with pressed concrete slabs and tiles, natural stone and timber decking tiles. In fact anything which has a straight edge can be used in conjunction with ASP adjustable support pads. The head plate holds the corner of four slabs. It has four integrated postioning “lugs” which the slabs will butt up to. These lugs provide a clear space between each slab which allows the drainage of rainwater between and beneath them. They also give a clear paving line, so the slabs can be laid in a straight line quickly and easily. They range in height from 25mm up to 220mm. We can also supply a smaller 22mm support as part of our MEGAPADS range, please see page 14. A large range in height is often required where drainage channels or pipework need to be overlaid, and a seamless finish can be achieved since the head plates and basepates are identical, so the finished paving is consistent in look across the area. WHERE A VERY HIGH CLEARANCE IS REQUIRED, AND TO COPE WITH CONTINUOUS CHANGES TO THE CONCRETE DECK BENEATH, ADJUSTABLE SUPPORT PADS ARE THE BEST WAY TO ENSURE TOP QUALITY FINISHES TO ROOFS, BALCONIES AND TERRACES. 10 Slope correctors can be fitted to the baseplates of all ASP supports. Please see page 20 for more information. The support pad is made up of four sections: The base plate is a solid, round base measuring 200mm in diameter. In the centre of the base is a round collar in which the stem and nut will sit. It is designed so that the weight will pass down the stem and onto the outside of the collar, and then pass down along the diagonal arms spreading out across the face of the base plate. This ensures that the weight is spread to the maximum possible area and does not concentrate on the core (with the risk of digging into the membrane beneath). The stem is manufactured with a thread to accommodate the nut fixing. The nut can be twisted up and down on the screw thread to adjust the height of the support pad. Installers can adjust the height either before laying the slabs and set the levels with a laser, or can level up the paving by hand once the slabs are in situ. Wallbarn can supply our “Easykey” to help twist the collar if required. The height range of each stem is marked in a small hole at the top. The headpiece slots into place on top of the stem. It is designed to hold the corners of four slabs, held in place by the four positioning lugs. HEADPIECES The standard headpiece measures 2.2mm wide and 18mm high. This will hold a 50mm slab in place effectively and gives a sufficient amount of drainage between slabs. Wallbarn can offer variations to this standard headpiece, according to the needs of the client. If installers are looking for a larger gap between the paving slabs, a 4mm wide lug can be supplied which will allow a greater amount of water to pass through the gaps. This may be required where there is a risk of sand or dirt clogging up the gaps, for example. A 10mm wide lug is also available, although designers should be sure that such a large gap does not present a trip hazard in some instances. If very large paving slabs are being installed, or if thinner tiles or more delicate softer stone is being used (such as slate) then it is recommended that a support pad is placed underneath the centre of the slab to give added support. A flat headed support should be used in this instance. The headpiece is completely flat, so will not scratch the paving or interfere with the levels. standard headpiece 4mm wide lugs 10mm wide lugs flat headpice Short lugged 2 lugged headpiece headpiece 11 Where thinner tiles are being installed, the standard height lugs may be too visible for a truly fine finish. A shorter, 10mm high lugged headpiece is available should this be the case. If irregular paving patterns are being laid, often a slab will need supporting, not only at the corners but also in a T junction or across a larger span. In these instances, the two lugged headpiece can be fitted onto the support pad to allow just two slabs to be supported at the edge. These headpieces are also useful when paving directly up the parapet wall (please see the section below). You can fit loose fitting cross spacers onto these supports if you require a wider gap between the slabs. Cross spacers (featured on page 7) are available 3mm, 4mm or 5mm wide. PAVING UP TO THE EDGE The edge of the paving can be handled in two ways: either a border of washed pebbles can be placed along the edge to finish off the paving line and ballast the edge of the roof (also helping to keep people from walking on the edges of the roof), or installers can pave directly up to the parapet wall or upstand. If they wish to pave up to the edge, they will need to cut the base plate back slightly to the central column so that the edge of the headpiece and the base plate are in parallel. That way, when the support is moved up to the wall both headpiece and base plate touch the wall. Care should be taken when shaving back the base plate not to touch the column in the centre as this may affect the stability of the support. Wallbarn’s new ASP MB support pads have a smaller base plate measuring 150mm in diameter. These new base plates can withstand the same weight tolerances as the standard bases, and can be useful for achieving tidier finishes up to edges and parapet walls. They are featured on page 13. 12 The adjustable supports are ideal for areas where a seamless terrace or walkway is required but the deck has multiple steps or ridges. Even large differences in the height of the deck can be alleviated, creating one level across the whole area. Two of the positioning lugs will need to be removed from the headpiece so that two (rather than the normal four) paving slabs will sit onto it. Customers can order our special 2 lugged headpiece (featured on page 10) These can be butted up to the wall. The other side of the paving slabs positioned up against the wall will rest on support pads in the normal manner – i.e. one corner on each quadrant of the support pad. The paving can then be extended across the rest of the deck area. Support pads are a useful way of laying slabs as ballast for insulation in the inverted waterproofing system. The support pads create a separation between the flags and the insulation, preventing the flags damaging the insulation boards in any way. The manner in which the base plates spread the weight of the slabs ensures that they do not dig into the insulation boards. As long as a suitably heavy paving slab is used, the insulation will be held in place and the area above can be utilised. This is a major advantage to the old fashioned method of using pebbles as ballast (which also carried the risk of stones getting beneath the insulation and possibly damaging the waterproofing membrane). # Please note - positioning lugs come in a standard size of 2.2mm thick and 18.5mm high, special lug sizes are available.

All ASP supports from 25mm up to 220mm high can be mounted onto this smaller base, which means tiles as small as 20 x 20cm can be properly supported and the cavity below still allows the free flow of rainwater from the surface. These smaller base plates are coded ASP-MB. The mechanical properties for these supports are almost identical to the standard ASP supports. Care should be taken, however, that the smaller tiles being installed on top of these new supports are heavy enough to ballast the deck properly. NEW FOR 2012 EXTENSION SHANKS FOR ASP SUPPORTS Wallbarn introduces a new extension shank to the ASP support pads, giving far larger heights than previously offered. We have designed a new extension shank measuring 145mm high which can be fitted into the base plate of the ASP support to increase the height up to a maximum of 365mm. This new extension can be applied to supports of 65mm and higher, but they allow installers to continue using ASP supports to much larger heights. This extends the current range from 220mm at its highest up to 365mm, whilst still maintaining the weight tolerance and stability associated with Wallbarn ASP supports. By taking these extension shanks customers will be buying a kit of supports and shanks. Therefore when ordering customers must be aware they will need to request ASP – EXT range of supports. ASP – EXT-EXTRA Another new development is the EXT-EXTRA support. This pad has an extra-long threaded stem measuring 170mm in total, which allows a Wallbarn ASP support pad to range from 210mm to 380mm, giving installers a huge range of height variation when laying slabs across very complicated deck areas. This means customers can take a single product and be confident the whole area can be installed without having to order multiple sizes of units. Both ASP EXT and ASP EXT EXTRA supports can have slope correctors fitted to their bases, and can be used with standard bases or the new 150mm diameter base plates.

The individual pads have a much larger range of adjustment than the ASP range, which can make installation simpler since a smaller number of different sized units can be chosen even for very large falls. They are heavy duty and extremely hard wearing with a weight tolerance of 800kg; double that of the ASP or TD range. Not only are they fully adjustable, but once the desired height is achieved, they can be locked into place, so that the thread does not start to unwind itself (with the possible risk of the slabs becoming unlevel). Some roof finish designs call for a very high cavity beneath the paving slab, and there can be complicated areas where steps and many multi-levels across the deck are present or where voids are required to cover services, ducts and gulleys. Drainage integrity is maintained between and below the slabs without interference with the top deck. Megapads are the optimum product for such areas and provide a uniform, standard support mechanism across the entire area with an identical interface between slab and deck. The Megapad units are made up of fixed sections (called Towers) which click into the sheath securely, and an adjustable section on the top end of the support which holds the headpiece. The amount of height adjustment depends on the size of the unit. The taller Megapads have a height range of 100mm each. Each section is locked into place using the “Multi-function Easy Key”. The key is used to help turn the supports at the thread, but also click into “locking holes” once the desired height is achieved and lock the threads. Additional collars are then wound up and down to brace the thread in place. This ensures that none of the elements work their way loose over time and the upper surface is completely secure. MEGAPADS OFFER INSTALLERS A MUCH LARGER RANGE OF HEIGHT WHEN LAYING PAVING SLABS. THEY ARE ALSO A MORE HEAVY DUTY SUPPORT, ALLOWING GREATER WEIGHT TO BE BOURNE ONTO THEM. 15 NEW SMALLER MEGAPADS Feedback from applicators stated that they often had to contend with very low height thresholds, particularly in retro-fit projects. Previously Wallbarn could only provide solutions from 35mm upwards, but now we have recently developed two new, smaller Megapad sizes – the 22-30mm and the 28-37mm Megapad. Manufactured in a similar manner to the higher range Megapads, these polypropylene units have a flat headpiece and base plate measuring 150mm in diameter. The lug separators are supplied as separate units, which clip into the central hole to provide the 2mm gap between paving slabs. The integrated thread in the central column allows for height adjustment. If a wedge is required, a loose fitting rubber disc (shown on page 7) can be placed underneath. These mini Megapads can also be fitted with TD headpieces for use with decking. Please see page 19 for more details. PAVING UP TO THE EDGE Edges and end-of-runs can be paved more effectively and securely with the Megapad system. The lug headpiece is removable, the support pad can be turned upside down and the lug head unit is placed onto the bottom of the base plate. The base plate is 200mm in diameter, so when turned upside down it exceeds the diameter of the (old) head piece and can butt up to the wall completely. Therefore the paving slab sits securely onto the plate and does not overhang the supporting columns. The headpiece will support two (rather than four) slabs in this case. The slabs are thus fully supported and stable and are in direct contact with the wall without problems. The weight and force is directly vertical and down through the shaft. Even at their maximum height these supports are stable and secure. They are designed to be easy to install and adjust. For complicated areas slabs can be installed and then final minor adjustments can be made by hand when the slabs are in situ, without the need for constant re-setting. They work very well on areas where there are large differences in the deck level. Megapads are designed to incorporate SLOPE CORRECTORS, wedge shaped discs which clip onto the underside of the baseplate where the fall of the deck needs to be addressed. Please see page 20 for more details. IMPORTANT – Megapads are now available with a TD timber decking joist headpiece. Please see page 19 for details.

There is renewed interest in decking areas, as developers seek more efficient use of the building footprint and outdoor space (for example for designated smoking areas) becomes more important. Since many waterproofing systems are fairly delicate, to simply lay timber directly onto the membrane runs too much risk of damage. Wallbarn’s TD range was developed to provide a solution to this problem. The strong polypropylene pads raise the decking off the roof deck, allowing proper drainage, preventing the timber digging into the membrane, and keeping the wood out of standing water, helping to prevent rotting. Wallbarn found that roofing contractors wanted to be in control of this element of construction since warranties can be at stake. We developed an easy, fast system so roofing contractors can do the work themselves. Because the supports are adjustable, applicators do not need to cut multiple thicknesses of timber to create a level surface, they simply turn the thread on the telescopic stem. The system is simple – the pads are loose laid onto the deck, the heights are adjusted at the stem across the deck by hand to ensure the upper surface is level, a joist framework is constructed sitting on top of the supports, and the top layer of decking planks are fixed to the joist frame. It is designed to be loose fitted. The supports are not drilled or bonded to the deck and the joists sit on them without being fixed. The weight of the timber and the fixings will hold everything stable and in place. The void between the decking and the roof can be used to hide items such as water pipes, electrical wiring and drains. Attractive light or water features can also be incorporated into the decking fairly easily. The end result can be stunning. The adjustable supports are similar in most ways to the paving pads, apart from the design of the headpiece. We manufacture a headpiece with pegs positioned in the corners, either 40mm or 60mm apart. This means a 2 inch joist or batten can fit in between the pegs or lugs easily and there is a little extra room in case some of the timber is twisted or swollen. The battens are laid onto the supports no more than 600mm apart. We recommend that only properly pressure treated wood is used, since these supports are used on outdoor decks. Cross battens are screwed into place to give a framework which is sturdy and weight bearing. It is sometimes advisable to also fix the joists to the parapet wall or upstand for additional strength. The decking planks – the timber which will be visible to the end users, is screwed onto the joist framework. WALLBARN SUPPLIES THE TD RANGE – SPECIFICALLY DESIGNED FOR SUSPENDED TIMBER DECKING ON ROOFS AND BALCONIES. 17 All of the TD range can have slope correctors added to the base plates to arrest the fall where necessary. Remember to lay TD supports a maximum of 600mm apart so as not to overload the system.

This frame should be able to withstand weight and vibration The decking layer is then fixed onto the joists using wood screws. A small gap between each plank of decking should be made to help with drainage. A stunning finish can be achieved with a natural, luxurious look to the terrace. The decking runs seamlessly up to the border, planters and door threshold.

The headpiece is clicked into place in the same way as the 40mm / 60mm headpiece, and is priced the same. It will be able to take a larger joist which will give added strength to the whole system. Wallbarn can therefore give a much greater amount of flexibility to installers as they can be assured that even larger sized battens will not slip off their mounting. Having a larger batten in place allows for more weight displacement through the system, but care should always be taken not to overload the support pads. Each pad will tolerate 400kg, but if the span is too great the load bearing is multiplied. Wallbarn recommends a maximum span of 600mm between support pads. ALTERNATIVE HEADPIECES FOR TD SUPPORT PADS FLAT HEADED ADJUSTABLE SUPPORTS FOR USE WITH TIMBER DECKING If a very wide joist beam is being used and even the 90mm gap on TD supports is not sufficient, a flat headed support pad can be used to hold the joist. These headpieces are 120mm in diameter and completely smooth. They give extra support without anything protruding up from the surface and potentially interfering with the levels. Provided that the joists are fixed together with cross battens and built into a framework, the whole structure will be sturdy, weight bearing and secure. Flat headed support pads can also be used beneath the centre of paving slabs where extra support is needed, for example, very large (over 600mm) flags or thinner tiles. They are priced at the same level as the ASP and TD range. NEW MOVEABLE HEADPIECE FOR TIMBER JOISTS – TD MOBILE A new moveable headpiece has been developed to fit onto the TD adjustable support pad range called TD Mobile, which allows installers to fix battens to the headpiece more easily. The headpiece clicks into place on top of the stem in the same way as all other headpieces, but the side bar can be moved along the face of the headpiece to adjust the width from 30mm up to 90mm. The measurements are clearly marked on the headpiece which helps installers guarantee exact spacing along the decking line. The load will always remain on top of the central axis, preventing movement. There are small holes in the side bar which allow screws to be passed through the headpiece and into the joists themselves. With the joists fixed to the supports and the decking fixed to the joists the whole decking system becomes very stable and secure. This new mobile system is seen as more versatile than the traditional TD headpiece, and is priced at a premium. 19 MEGAPADS FOR TIMBER DECKING NEW TD TIMBER DECKING HEADPIECES FOR MEGAPADS – LESS UNITS REQUIRED PER M2 Wallbarn can also announce a brand new headpiece for Megapads specifically for timber decking. These headpieces will launch at the start of 2012. The headpieces click into the centre of the flat head of all Megapads to house a timber joist securely in the same way that the TD headpiece does for our other adjustable range. The distance between the lugs is 60mm which will house a 2 inch joist. Because the Megapads can withstand a load of 800kg per unit, when using them for timber decking a larger span between each unit can be allowed, and with less Megapads being required, a significant cost saving can be achieved. The extended range of adjustment (105mm for the larger sizes) means that less different sizes are required than for the TD support range, making purchasing an easier task. The locking mechanism on the stems also means that there is no risk of the supports starting to unwind themselves, which may cause changes in the level and instability. Ask for Megapad TD when laying timber decking. FLAT HEADED MEGAPADS Megapads can also be used to support timber decking by simply removing the lug connector from the headpiece. This creates a completely flat headpiece of 200mm diameter (or 150mm for the very small Megapads) and gives installers greater flexibility. Because Megapads can tolerate a greater amount of weight – 800kg each – the system is more secure. A far greater amount of height range is achievable with Megapads, which make them suitable for very complicated areas which designers want to cover with one seamless timber decking layer.

They are suitable for use with ASP, TD and Megapad supports; including the new mini-Megapads, ASP MBs with the 150mm diameter base plate, the ASP EXT and ASP EXT EXTRA range. They are designed to arrest the fall of the roof or deck beneath – even “flat roofs” will be built to a fall for drainage, and by having these wedges attached underneath, the support pads remain completely vertical and straight, which ensures the force of gravity runs directly vertical, preventing tilting and keeping the support pad more stable. They are very easy to apply to the base plate. For the 200mm diameter base plates a simple clip mechanism fixes around the lip of the plate. All 150mm base plates have a groove inside the perimeter which slots into a series of rings situated on the slope corrector. More than one slope corrector can be applied if required as one can clip onto another. They can be used with both timber decking supports and paving supports. The height of the support pad can still be adjusted once these are in place, and the material is the same polypropylene as used for the support pads (although they contain an element of recycled material). Slope correctors are available in three sizes, with a 1%, 2% and 3% gradient. The clip design and diameter of the corrector is the same for all three gradients, it is simply the amount of slope which is different. The gradient or slope is measured as a percentage. The deck is most commonly laid to a fall around 1 in 40, so a 2% slope corrector is normally chosen. Additional slope correctors can be added where required.

Traditionally laying timber decking directly onto these deck surfaces led to additional costs of employing specialist carpenters and presented concerns of the timber damaging the waterproofing membrane which it came into contact with. Hardwood timber decking tiles installed in conjunction with Wallbarn support pads offer an ideal alternative. Installers avoid the need to lay joist frames and drill planks into place. They are ideal when only a low height threshold is available. The tiles measure 500 x 500 x 30mm and are mounted onto ASP or Megapad supports. The crucifix shaped positioning lugs hold the square edges securely in place. The tiles are suspended on the supports in the same way as a paving slab. The weight of the tiles holds the system in place. The major advantage of this system is that if the deck beneath ever needs to be inspected, a tile can be easily lifted up. Unsightly objects such as roof drain outlets, pipework and services can be covered and accessed at any time. Beautiful finishes can be achieved with the minimum of disruption and labour. TYPE OF TIMBER AVAILABLE Wallbarn has specially chosen timber which is ultra-hard and dense to repel moisture and rotting, with smooth grains that are unlikely to splinter or scratch on the surface, resistant to insect and mildew damage, and are extremely strong and weight bearing. The main types of timber used are: Ipe from Brazil is one of the toughest most durable woods available. It has a greenish brown appearance and because of its tight grain is recognised for its high resistance to mildew, termites and rotting. It is very low maintenance and is used extensively in marine and exterior construction due to its resistance to water. It dries very well and becomes extremely hard, which means it has to be pre-drilled and cut with a mechanical saw. It carries a Class A fire rating and will last well over 25 years. It is nicknamed “ironwood”. Sucupira is also from Brazil and is again is extremely hardwearing timber. Chestnut coloured, it is a little more course in the grain than ipe and is a little less strong, but is still ideal for external decking in the UK climate and will last for 20 years. Further timber is also available as non-stock items, including Green Heart, Garapa, Cumaru and Massaranduba. Wallbarn can also source timber tiles in different timber if there is a specific requirement. All timber used in Wallbarn hardwood timber tiles has been selected to withstand long-term exposure to the UK weather. They are resistant to decay and water ingress and provide a superior, permanent wood finish on exterior decks. The timber will fade in colour over time and become silvery grey in the sunlight. Natural oil can be used to enhance the original colour should users wish, although varnish or lacquer is not recommended. Wallbarn hardwood timber decking tiles can be used on a wide range of applications from small domestic rooftop decks to large-scale public areas. TIMBER DECKING TILES PROVIDE THE EASIEST SOLUTION TO LAYING TIMBER DECKING ONTO ROOF DECKS AND TERRACES. 23 They are the easiest, most cost effective way of installing top quality hardwood decking on rooftops and terraces. Using hardwood timber tiles and adjustable supports is a far easier way to achieve the correct level on terraces. Whether tiles are being laid in conjunction with materials such as the green roof section (pictured left) or laid up to a safety rail or damp proof course (right) this system achieves accurate levels easily, saves a great deal of labour and avoids the need for constant cutting of timber joists and re-measuring. FSC® CERTIFIED TIMBER Wallbarn has achieved Forest Stewardship Council® Chain of Custody certification. This means Wallbarn is certified to supply FSC certified timber. The FSC scheme means that the certified timber can be traced back to well-managed forests in accordance with the rules of The Forest Stewardship Council. Every party, from the grower to the processor to the manufacturer of the tiles to the end user is tracked and audited to ensure that they have complied with the ethical and well managed forest practices laid down by the FSC. The whole chain is monitored. FSC 100% Chain of Custody certified timber - number SGS-COC-007242. Only fully certified companies within the Chain of Custody can use the official FSC logo against FSC certified timber. FSC credited timber is clearly distinguished and marked as separate from non-FSC timber and the mark can only be used with FSC material. Please contact us for full details of compliance to FSC Chain of Custody and ask what we can offer. The timber decking tiles can be cut into shapes to fit around awkward areas, edges and details without becoming unstable, due to the reinforced underside. The grain is smooth and uniform in most cases, so sawing and drilling is possible. However, because the timber is so dense and strong Wallbarn recommends that carbide tipped saw blades are used when cutting the tiles. Saw blades will become blunt very quickly when working these types of timber. Wallbarn recommends pre-drilling all holes before screwing into the wood. All the tiles are manufactured with a reinforced underside. Each end has an additional plank fixed with rust-resistant screws. A diagonal cross beam provides extra strength and durability. Border planks made from the same timber can be fitted to the edges of the tiles to help give an attractive finish. 24 TIM B E R D E C K IN G TILE S TE C H N IC A L D A TA RR AAWW MM AATTEERR IIAALL IIPPEE CC UU MM AARR UU GG AARR AAPPAA GG RR EEEENN HH EEAARR TT MM AASS SS AARR AANN DD UU BBAA SS UU CC UU PPIIRR AA BO TAN ICAL N AM E LAPACH O , TABEBUIA SPP, DIPTERYX O DO RATA APULEIA LEIO CARPA LAURACEAE, M AN ILKARA SPP, BO W DICH IA SPP, O CO TEA RO DIAEI SAPO TACEAE LEGUM IN O SAE GG RR EEEENN DD RR YY GG RR EEEENN DD RR YY GG RR EEEENN DD RR YY GG RR EEEENN DD RR YY GG RR EEEENN DD RR YY GG RR EEEENN DD RR YY DEN SITY 960 KG/M 3 994 KG/CM 3 910 KG/M 3 1,138 KG/CM 3 670 KG/M 3 830 KG/M 3 970 KG/M 3 833 KG/M 3 1000 KG/M 3 940KG 780KG BEN DIN G STREN GTH 1,579 KG/CM 2 1,825 KG/CM 2 1,357 KG/CM 2 1,917 KG/CM 2 956 KG/CM 2 1,278 KG/CM 2 1,427 KG/CM 2 1,842 KG/CM 2 1,193KG/CM 2 1,658KG/CM 2 1505 KG/CM 2 668 KG/CM 2 CRUSH IN G STREN GTH (GREEN ) 1,825 KG/CM 2 725 KG/CM 2 1,917 KG/CM 2 634 KG/CM 2 380 KG/CM 2 554 KG/CM 2 380 KG/CM 2 554 KG/CM 2 746 KG/CM 2 941 KG/CM 2 SPECIFIC GRAVITY 0.92 1.08 0.86 0.9 .66 0.97 0.85 1 0.8 1 H ARDN ESS 1,671 KG 1,606 KG 740 KG 1,072 KG 980 KG 973 KG SH EARIN G STREN GTH 114 KG/CM 2 129 KG/CM 2 135KG/CM 2 139 KG W EIGH T 994 KG/CM 3 1,138 KG/CM 3 835 KG/M 3 1,030 KG/CM 3 1,110 KG.M 3 RADIAL SH RIN KAGE 6.6% 5% 4.4% 7.5% 6.8% 5.6% TAN GEN TIAL SH RIN KAGE 8% 7.6% 8.5% 8.2% 11% 8.4% VO LUM ETRIC SH RIN KAGE 13.2% 12% 14% 17% 19% 15.1% CO LO UR DARK GREEN TO DARK BRO W N CH ESTN UT H O N EY CO LO UR YELLO W ISH BEIGE TO YELLO W ISH BRO W N TO LIGH T RED, BECO M IN G DARKER REDDISH DARK BRO W N TO REDDISH BRO W N YELLO W ISH BRO W N O LIVE CO LO UR IN TIM E TEXTURE FIN E, TIGH T GRAIN UN STRESSED FIBRO US FIN E, SM O O TH GRAIN FIN E, UN IFO RM GRAIN FIN E, STRAIGH T GRAIN M EDIUM , IRREGULAR GRAIN BUT TURN S EASILY DURABILITY VERY H ARD, ALM O ST RESISTAN T TO FUN GAL AN D RESISTAN T TO TERM ITES, H IGH LY RESISTAN T TO RESISTAJN T TO DECAY FUN GI RESISTAN T TO FUN GI CO M PLETELY RESISTAN T TO M ARIN E ATTACK, H IGH M ARIN E ATTACK, FUN GI TERM ITES AN D DECAY FUN GI AN D TERM ITE, LO W AN D TERM ITES TERM ITES, FUN GUS, M ARIN E RESISTAN CE TO DECAY AN D DECAY RESISTAN CE TO AM RIN E ATTACK ATTACK AN D DAM P AN TICIPATED LIFESPAN O VER 25 YEARS O VER 20 YEARS UP TO 15 YEARS O VER 20 YEARS 10 YEARS UP TO 20 YEARS SIZE O F TILE 500 X 500M M 500 X 500M M 500 X 500M M 500 X 500M M 500 X 500M M 500 X 500M M TH ICKN ESS O F TILE 30M M 30M M 30M M 30M M 30M M 30M M W EIGH T O F TILE 5.7KG 5KG 4KG 4.75KG 4.5KG 5KG SAW IN G CH ARACTERISTICS REGULAR BUT BLUN TS DIFFICULT, SPLITS DUE TO RELATIVELY EASY RELATIVELY EASY W ITH A DIFFICULT – PRO N E TO SPLITTIN G DIFFICULT DUE TO IRREGULAR M ACH IN ERY Q UICKLY DUE TO IRREGULAR GRAIN STRAIGH T GRAIN BUT BLUN TS SPLITTIN G AN D W ARPIN G IRREGULAR GRAIN , CAN EXTREM E H ARDN ESS M ACH IN ERY Q UICKLY DUE SPLIT AT EN DS TO H ARDN ESS DRILLIN G CH ARACTERISTICS EASY BUT BLUN TS EASY W ITH DEFECTS, H IGH EASY BUT H IGH Q UALITY DRILL EASY W ITH DEFECTS, H IGH GO O D - DRILLS EASILY GO O D - PRE BO RIN G M ACH IN ERY Q UICKLY DUE TO Q UALITY DRILL BITS REQ UIRED BITS REQ UIRED Q UALITY DRILL BITS REQ UIRED W ITH LITTLE DEFECT N ECESSARY EXTREM E H ARDN ESS FIN ISH IN G CH ARACTERISTICS GO O D - SM O O TH GO O D W ITH M IN O R DEFECTS GO O D - SM O O TH GO O D - SM O O TH GO O D BUT CAN CAUSE M IN O R GO O D - SM O O TH SPLIN TERIN G DRYIN G CH ARACTERISTICS EASY W ITH LITTLE O R EASY W ITH SM ALL DEFECTS SLO W W ITH LITTLE O R N O SLO W W ITH A RISK O F DEFECTS DIFFICULT AS TH E W O O D IS FAST W ITH LITTLE O R N O DEFECTS DEFECTS PRO N E TO SPLITTIN G, W ARP DEFECTS AN D CASE H ARDEN IN G FIRE RATIN G CLASS A H IGH RESISTAN CE H IGH RESISTAN CE CLASS A CLASS A 25 MEMBRANES 26 AN EASY TO USE SELF-ADHESIVE WATERPROOFING MEMBRANE FOR DRY, CURED CONCRETE FOR TANKING AND PODIUM DECKS. WALLBARN PRO-SEAL Pro-seal is a new damp-proof and waterproofing membrane from Wallbarn. It is a cold applied, easy to install sheet membrane made from elastomeric modified bitumen, designed as a fast, effective waterproofing solution for both horizontal and vertical surfaces. It has excellent adhesion and flexibility properties and can accommodate some movement. It has high tensile and puncture resistance, possesses superior tear strength, and can be installed without any requirement for special tools or techniques. It can be used on areas such as roofs, basements, wet areas, canals, culverts and civil engineering works. It is especially suited to tanking and subterranean waterproofing on a vertical plane. Pro-seal has the following advantages: • It is a much faster, cleaner way to seal and secure structural concrete than with liquid membranes • It is safer than using super-heated materials • It is non-toxic and safe to handle • It is easy to handle and install, cutting out mess • Multiple sheets can be bonded together to form a single membrane • It is reinforced with an integrated mesh • It ensures a consistent, uniform thickness Pro-seal is a reinforced membrane manufactured with an HDPE film backing on one side. The other side is covered with a slip release paper layer which is peeled off before the membrane is applied to the surface. The paper ensures that the bitumen does not become contaminated with dirt or grit, or stick to itself on the roll, making it much easier to measure and install. Once the first section of the bitumen is positioned into place the paper can be peeled off. This design helps ensure that applicators can install a viable, reliable waterproofing membrane quickly and effectively onto concrete surfaces. Application is fast and simple. The membrane can be cut into shapes easily and because of the self-healing properties of the material, multiple sheets can be joined together to form one seamless membrane across the structure. It is essential that a bitumen primer is used on the concrete prior to pro-seal being installed. 27 Pro-seal is not a tacky material, unlike some other bitumen sheet membranes, and a fair amount of pressure is needed to bond the membrane to the surface. A wooden roller is recommended for installation. The bond will increase over time. It is important that none of the membrane gets snagged onto the structure before applicators wish to fix it into position as this may compromise the seal. The slip paper ensures this does not happen until the applicators wish to do so. Pro-seal comes in a thickness of either 1.5mm or 2mm. It is extremely tough and durable. Unlike many other self-adhesive membranes on the UK market, all Wallbarn Pro-seal membranes are manufactured with an integrated reinforcement mesh, made from either glass fibre or polyester. This gives them far superior tensile strength and puncture resistance, whilst still maintaining full flexibility. Please note that Wallbarn Pro-seal is not suitable for wet, damp or uncured concrete structures. Always ensure the concrete is dry. It is advisable that the Pro-seal membrane is covered with some sort of protection. Wallbarn Protecto-board can be torch-bonded to the waterproofing, or Protecto-drain HDPE membrane is suitable for areas which may require drainage management.

Made from a mixture of synthetic fibres saturated with at least 75% bitumen, Wallbarn Bituminous Protecto-board is completely waterproof and provides superior impact and abrasion resistance. It is lightweight and easy to handle, and can be cut, shaped and installed in a wide variety of applications and areas. It is particularly suited to vertical applications as it can be bonded to concrete or the waterproofing membrane effectively without interfering with the seal. Wallbarn Bituminous Protecto-board is available 3mm and 6mm thick. It is suitable for use with bituminous waterproofing systems. It is highly adaptable. It can be spot bonded using adhesive, fixed with double sided bitumen tape, or heat bonded to the surface. Multiple sheets can be bonded together to form a uniform layer, and because of its light weight, it can be held in the vertical position in the long term. The material is supplied in 1m x 2m sheets. Each sheet is covered both sides with a polyethylene film. This film also avoids the bitumen bleeding onto other surfaces and ensures against the sheets sticking together in warmer weather when stored on a pallet. Protecto-board is suitable for basement tanking, podium decks, roofs, tunnels, waterways and civil engineering projects. By installing a protection membrane applicators can have an added assurance that waterproofing membranes will be protected over time, and they can avoid the unnecessary expense and trouble of having to investigate and identify future leaks on the completed structure. They can be used as a permanent layer, part of the waterproofing system, or as a temporary protection which is removed after the passing trades have finished. PROTECTO-BOARD IS A SHEET MEMBRANE WHICH PROTECTS DELICATE BITUMINOUS MEMBRANES FROM DAMAGE. 29 The most effective way to install Protecto-board is to heat bond to the surface requiring protection. This gives a secure bond and complete coverage, with no risk of dust, stones or water passing behind the protection and potentially affecting the membrane. The boards are flexible enough to manipulate and shape around particular details. The sheets can be scored or cut with a sharp knife to fit around corners and multiple layers can be fitted on top of one another to give extra protection on susceptible areas. Protecto-board is designed to be user friendly and easy to install. Unlike some other bituminous boards on the market, the bitumen content is held within the structure of the board, and will not bleed out of the fibres. This cuts down on a considerable amount of mess for both surrounding structures and personnel handling the product during installation. Being relatively lightweight also helps the installation process. The boards are very tough and durable and can withstand concrete pour easily. Even shingle is successfully repelled. The boards are rot-proof and will not delaminate even when immersed in water, unlike many card fibre based protection boards on the market. They are intended to provide long term protection for waterproofing systems.

It is very tough but lightweight and easy to handle, making it very adaptable and suitable for a large number of applications. It is also completely safe and contaminant free, and can be used safely with water courses. It is ideal for vertical surfaces and protects the waterproof membrane from abrasion and puncture damage caused by backfilling. Its cupped structure creates a permanent air gap between the wall and the backfill which helps to reduce pressure points and helps in the ventilation of the building and problems of damp. Gravity will encourage the water to flow down the surface and into the sump or drain constructed beneath. It is also an effective damp-proof layer on horizontal surfaces. It is fungus and rot-proof and completely safe with drinking water. PROTECTO-DRAIN 8 Protecto-drain 8 is a single membrane fixed to the wall with its cups facing towards the backfill. It spreads the weight of the soil and prevents point loading onto the structure. The 8mm high cups create an air gap between the structure and the earth backfill, helping to ventilate it effectively. Providing that the membrane is properly sealed at the edges, Protecto-drain 8 can create a viable waterproofing membrane in itself. It is best suited, however, as an extra protection and ventilation layer, covering an existing waterproofing seal. Protecto-drain 8 is very flexible, and can be folded and shaped around awkward areas and details without compromising the seal. Because it is so lightweight, it is ideal for fixing to the vertical plane. It is easy to cut around details and edges and multiple sheets can be fitted together. It should be fitted so that it emerges above the surface ground level to ensure the air gap does not become blocked or flooded. Each sheet should be overlapped by 20cm, with the egg box shaped cups slotting neatly into one another, producing a good fit. The sheets are fixed to the structure either by passing nails through special sealing plugs onto battens or by using a double sided bitumen tape at the edges of the sheets and across the joints. Using tape across the joints is advised to ensure a proper seal thoughout the whole area. Protecto-drain 8 is available as a standard 550gsm membrane. Special lightweight or heavy duty versions are also available. PROTECTO-DRAIN IS A PREFORMED HDPE MEMBRANE DESIGNED TO PROTECT DRAINAGE LAYER, FOUNDATION WALLS AND SUBTERRANEAN DRAINAGE COURSES AND HELP CHANNEL WATER EFFECTIVELY. 31 PROTECTO-DRAIN G8 Protecto-drain G8 is suitable for areas with a much greater amount of water passage and pressure through the ground. It has a 100gsm geotextile fabric bonded to one side. This gives additional protection to the membrane and also helps to filter out particles but allow the water to pass through the fabric and into the air gap drainage chamber. With moisture passing through the geotextile but no soil moving, the area around the structure is effectively drained but the ground remains stable and firm, greatly reducing the risks of subsidence or hydrostatic pressure building up. This membrane is designed for a water management, rather than water prevention system. Any subterranean structure will come into contact with significant moisture, so a way to channel this moisture away from the concrete is required. A suitable exit for the water should always be designed into the waterproofing system. As the water drains vertically down the membrane, it should be channelled into a perforated pipe. The geotextile fabric can be pulled away from the HDPE membrane at the bottom of the structure to wrap around the pipe with the HDPE membrane passing beneath it. This way all the moisture will collect in the pipe but still be kept away from the structure. The drainage pipe should be fitted to either a natural drain or a pump to ensure the water moves away from the structure effectively. Protecto-drain G8 is ideal for planters and tanking. It is essential to avoid vegetation becoming waterlogged in planters but at the same time ensuring an even flow of moisture though the soil so that flood channels are not created in the planter, which can also damage the roots of the plants. It can be manipulated into tight spaces to provide a complete lining for planters, waterproofing and protecting the structure. The sheets can be overlapped to provide a continuous seal and the geotextile fleece ensures particles do not clog up the drainage holes and the water run-off is filtered. Because the membrane is rot-proof, Protecto-drain G8 is an effective lining for planters in the long-term. The water running out of the planter will also not become contaminated by Protecto-drain G8 as the material is completely safe with drinking water. Protecto-drain G8 has also been used successfully on a horizontal plane as a drainage membrane beneath blockwork and paving slabs. The rainwater runs through the slabs and insulation, then through the geotextile fabric and runs along the HDPE membrane into the roof outlet. This prevents standing water puddling on top of the slabs and gives effective drainage. 32 PROTECTO-DRAIN 20 Protecto-drain 20 is a 1mm thick HDPE membrane which is useful for larger scale areas of tanking and sealing. It has a larger cup size of 20mm which allows a greater amount of ground water to pass along the membrane. It is ideal as a lining membrane on bridges and tunnels, and a whole manner of civil engineering works. The flexible and easy-to-bond nature of the material makes it easy to install, and it can cope with larger quantities of ground water and drainage quite easily. The HDPE material will not pollute the water running off in any way, which means that water can be directed, managed and recycled for a whole manner of uses. Protecto-drain 20 offers a much simpler, but often more effective way to manage and control subterranean water than many expensive systems and concepts. By sticking to simple principles of not stopping water but redirecting it, hydrostatic pressure points are prevented. By designing an “egg-box” profile, blockages are prevented and a greater amount of water can pass along the membrane. This profile also allows very easy sealing of the membrane, as multiple sheets can be “clipped into place” by overlapping the cups and sealing the joints with adhesive tape. In vertical applications it is very good as a waterproofing and protection layer between layers of concrete. It is tough enough to tolerate a wet concrete pour without risk of damage. When installed between two layers of concrete the cupped profile ensures a constant air gap between the two concrete layers, meaning the fabric of the building is sealed at the sides, so there is no risk of damp creeping into the concrete even if the building is subterranean in part. It is used extensively in horizontal installations beneath the initial concrete slab layers, where it is effective in preventing seepage water from below entering the foundations. Each individual sheet can be bonded together by overlapping the cups and sealing with tape, meaning the layer is completely waterproof. Since it is flexible, any undulations and imperfections in the ground below can be accommodated without risk to the seal. Rebar can be laid directly onto the membrane without damage and concrete can be poured. Protecto-drain G20, a 20mm HDPE membrane with a 100gsm geotextile bonded one side, is also available. 33 PROTECTO-DRAIN 20P Protecto-drain 20P was developed for use as a reservoir and drainage layer in green roof construction. It is placed on top of the waterproofed, protected concrete deck and sits beneath a filter layer, the soil substrate and vegetation layers on extensive green roof systems. The HDPE membrane is manufactured with the same 20mm cups, but the area between the cups is perforated. On a horizontal plane, this allows water to fill up in the cups helping to sustain the roots with any excess water escaping through the holes and able to run away beneath the membrane into the drainage outlet. This is a simple but effective way of holding a modest amount of water beneath the root systems but preventing the area becoming waterlogged, which will kill the plants. Because of the egg-box shape of the membrane, a constant air gap beneath the HDPE is maintained, allowing the excess water to pass easily without clogging. The water held in the cups can then be drawn back up through the filter layer to nourish the vegetation above. This means that a constant level of water can be held in the reservoir cups, but rainwater is efficiently removed effectively and quickly from the roof, which will not become overloaded (never underestimate the weight of standing water). It is important to remember, however, that these materials alone do not provide a drought resistant system. Regular watering and maintenance is required for all roof gardens and green roofs. Wallbarn Protecto-drain 20P is lightweight and easy to transport and install, making it ideal for rooftop applications. It is the perfect product for either large-scale roofs or small domestic projects. Large amounts of membrane can be installed in a day, as operatives can simply roll it out across the deck and overlap the edges quickly and easily. By installing the soil substrate immediately, the membrane is properly ballasted. Protecto- drain 20P is suitable for EXTENSIVE green roofs. This includes sedum roofs, wildflower and biodiverse roofs, grasses and dwarf plants, where soil substrates are up to a depth of 200mm. 34 PROTECTO-DRAIN 60P For INTENSIVE green roofs installers will need to use Wallbarn Protecto-drain 60P as the drainage membrane. Protecto-drain 60P is a rigid board made from recycled polypropylene, not HDPE. The cups are 60mm deep. With larger cups and more perforations, this membrane holds a greater amount of water and has higher drainage capacity, meaning the membrane is suitable where higher soil substrates, and a much larger degree of drainage is required. The membrane itself is 2mm thick. It has very good weight tolerance and compressive strength. The higher air gap beneath the green roof system means that a larger amount of water can pass through the system, reducing the risk of or hydrostatic pressure on the surface below. With higher substrate depths available, more variety of plants and vegetation can be planted on a green roof, including grasses, shrubs and trees. The frame is rigid, tough and weight bearing, and is designed so that each tray, measuring 500 x 500 x 60mm, can clip onto its neighbour, making installation fast and easy. Protecto-drain 60P can be cut easily to fit around details on the roof. The edges and base feet are rounded to prevent damage to the waterproofing membrane beneath. Applicators can walk across the membrane without problems due to its strength. It is so stable in fact, that structures can even be built onto it if required. Once the deck is waterproofed and protected, Protecto-drain is laid down. The soil/substrate is then installed onto the membrane up to the level required. Care must be taken to ensure that the particles do not clog up the cups so either a geotextile filtration layer should be loose laid onto Protecto-drain 60P or course aggregate with no fine particles should be installed as an intermediate layer before laying soil-type material. 35 PROTECTO-DRAIN ACCESSORIES AND SPECIAL PRODUCTS ACCESSORIES PROTECTO-DRAIN – SPECIAL PRODUCTS Wallbarn can offer variations on the standard Protecto-drain membranes, dependant on the technical requirements of the project. PROTECTO-DRAIN 8 LIGHTWEIGHT & PROTECTO-DRAIN 8 HEAVY DUTY Protecto-drain 8 is available in a lightweight 450gsm variety where strength is not so much of an issue and clients may require a more cost effective material. Wallbarn can also supply Protecto-drain 8 Heavy Duty for higher technical performance. We have supplied Protecto-drain 8 Heavy Duty in 700gsm and 900gsm. These superior membranes are 1mm thick rather than the standard 0.6mm thick and have superior crushing strength and puncture resistance. They have been used successfully as protection membranes for waterproofing and concrete pour on many high-specification projects. They are used where high loadings are expected, such as railways and airports. PROTECTO-DRAIN PL8 – PLASTER GRADE MEMBRANE Protecto-drain can be manufactured with a polyester mesh bonded to one side. Plaster and rendering can be laid onto the membrane and adheres to the surface, allowing internal walls to be constructed. Tile adhesive can also be installed onto the mesh. This material is very useful for internal tanking and basement rooms where the HDPE membrane acts as a waterproofing and damp-proofing layer, and the internal plaster can then be installed on top. Protecto- drain plaster grade material is ideal for retro-fitting of rooms in basements and underground installations. As well as the regular HDPE / mesh version, a membrane incorporating the HDPE membrane, the polyester mesh bonded one side and a geotextile fabric bonded the other side. This geotextile gives a protection and cushioning layer to prevent any risk of the waterproofing or delicate membrane immediately behind the Protecto-drain becoming damaged. A range of white fixing studs and edging strips specifically for the plaster grade membrane is available. Protecto-drain flexible HDPE membranes can be fitted to the structure using special fixing buttons, which fit into the dimples of the membrane. A nail is passed through the centre, and the buttons seal the hole made by the nail, helping to keep the membrane watertight. For longer fixings a specialised pin can be used to pass through the membrane. Again, it is self- sealing and the shaft is ribbed to maintain a strong bond into the structure. Double sided bitumen tape is also available for securing sheets together or bonding the membrane to a dry structure. Being bitumen based, the tape has very strong adhesion and is waterproof, not becoming affected by damp. 36 PROTECTO- PROTECTO- PROTECTO-DRAIN PROTECTO- TEST METHOD DRAIN 8 LIGHTWEIGHT 8 HEAVY DUTY DRAIN G8 MATERIAL HIGH DENSITY POLYETHYLENE (HDPE) COLOUR BLACK MEMBRANE THICKNESS (APPROX) 0.60MM 0.50MM 1MM 0.60MM CALIBRATED MEASURING TAPE DENSITY 550GSM 420GSM 900GSM 650GSM CALIBRATED MEASURING TAPE COMPRESSION 250KN/M2 170KN/M2 300KN/M2 250KN/M2 MDV LENGTH 20M 20M 20M 15M CALIBRATED MEASURING TAPE WIDTH 2M 2M 2M 2M CALIBRATED MEASURING TAPE CUP HEIGHT 8MM 8MM 8MM 8MM MDV NUMBER OF CUPS 1500 PER M2 1500 PER M2 1710 PER M2 1500 PER M2 MDV AIR VOLUME BETWEEN CUPS (APPROX. ) 5.5 L/M2 5.5 L/M2 5.5 L/M2 14 L/M2 MDV HORIZONTAL DRAINAGE CAPACITY 4.6 L/M2/S 4.6 L/M2/S 4.6 L/M2/S MDV RESISTANCE TO WATER PENETRATION W1 EN 1928 TENSILE STRENGTH - MD >_ 340 N/50MM >_ 330 N/50MM EN 12311-2 TENSILE STRENGTH - CMD >_ 350 N/50MM >_ 335 N/50MM EN 12311-2 ELONGATION - MD >_ 44.9 N >_ 28.7 N EN 12311-2 ELONGATION - CMD >_ 35 N >_ 26.2 N EN 12311-2 RESISTANCE TO STATIC LOADING NO PERFORATION AT 200 N/24HRS EN 12730 DURABILITY PASSED EN 1296 & EN 13984 EXPOSURE TO LIQUID CHEMICALS PASSED / WATERPROOF EN 1847 RESISTANCE TO IMPACT >_ 410MM >_ 410MM EN 12691 RESISTANCE TO TEARING - MD >_ 343 N >_ 332 N EN 12310 RESISTANCE TO TEARING - CMD >_ 352 N >_ 349 N EN 12310 WATER PERMEABILITY FILTER WEBBING 100 L/M2 TEMPERATURE TOLERANCE -30°C TO +80°C MDV RESISTANCE TO CHEMICALS ROT-PROOF, RESISTANT TO FUNGUS AND BACTERIA.

PROTECTO-DRAIN TECHNICAL DATA 38 GEOTEXTILES These nonwoven fabrics are permeable membranes which allow water to pass through but hold the particles in place. The soil does not become saturated, thereby improving the strength and stability of the ground. Geotextiles are extremely useful to help improve the condition of groundworks before starting construction. They are used extensively in road and rail construction and beneath concrete foundations and blinding layers. The makeup of the fabric is uniform throughout the roll, so no weak spots will be present in the layer. Geotextiles also provide a very viable, flexible, permeable protection and cushioning layer on areas such as reservoirs and landfills. A preliminary layer can be installed to prevent soil movement and stones from piercing delicate membranes above. They are extremely effective as subterranean soil stabilisation membranes. Either covering buried pipes or lining drains, they will ensure the passage of water without risk of land slippage, greatly improving the quality of the area. They can also be used on areas where new built-up ground is being created, such as artificial islands and reclaimed land, to prevent subsidence before the soil is fully consolidated. Wallbarn can supply a very large range of geotextiles, made from different materials in a whole host of densities and weights. We can select the exact product for the needs of the client and provide both the best technical performance and the most cost effective solution. Geotextile fabrics are available manufactured in polypropylene or recycled polyester. The material is supplied packed into tight rolls and we can supply material in a variety of roll sizes, from 1 metre wide up to 6 metres wide for very large-scale projects. These super-jumbo rolls make installation much faster and easier as there will be less individual rolls to sew or seal together – ideal for applications such as landfills. WALLBARN CAN SUPPLY a LARGE RANGE OF GEOTEXTILE FABRICS IN A NUMBER OF DENSITIES AND MATERIALS. THEY ARE IDEAL FOR A WIDE NUMBER OF USES – INCLUDING PROTECTION, DRAINAGE, FILTRATION, SOIL STABILISATION AND GREEN ROOFING. 39 The prime material supplied by Wallbarn is a high tenacity polypropylene fabric (PPS). This has been designed to be flexible and permeable but has increased tensile and puncture strength, making it suitable for hard wearing applications such as landfills and reservoirs. Its soft, cushioning properties mean it can be placed onto rough areas to prevent sharp objects from passing through into the system above but still allow the passage of water. This means sealing and waterproofing sheet membranes can be installed above them without the risk of ground settlement causing any damage above. This material is also ideal for road and rail construction, as it can withstand the forces of heavy traffic over the long term. The high tenacity PPS grade polypropylene fabric has also been used as an effective protection layer for waterproofing membranes including single ply sheet membranes. The cushioning effect is seen as a major advantage. It has been used successfully as a separation layer in inverted waterproofing systems, protecting the insulation from damage caused by the ballast. It can be used between layers of asphalt, in tunnels, foundations and airport runways. The properties exceed those of the leading brands on the market and very high performance can be achieved using these fabrics in a wide manner of applications. A second grade of polypropylene fabric is available called PPX. This is manufactured in a similar way to the high tenacity product, but it has slightly lower mechanical properties. The PPEX offers a more cost effective option for simple filtration or erosion control. Where there is not the requirement for such high tensile strength, a whole range of fabrics are available which still match the performance of many of the leading geotextiles in the market in a wide range of densities and roll sizes. RECYCLED POLYESTER GEOTEXTILE Designers and installers can choose a more sustainable option by using recycled polyester fabrics on some applications. Although these materials do not have the tensile strength and mechanical properties of the virgin fibre materials, where strength is not so much of an issue, recycled polyester fabrics can be used as an effective separation and filtration layer. They have proved popular in applications such as green roof systems and temporary protection layers. Wallbarn uses recycled polyester fabrics within its own green roof systems, details of which can be found later in this brochure. Wallbarn can supply a white recycled polyester fleece, coded PEI, or a multi-coloured polyester fabric, coded PEC. Technical details are given on pages 42 and 43. All Wallbarn geotextile fabrics are manufactured under ISO 9001:2000 standards and comply with Directive 89/10/EEC 1988 (as amended by 93/68/EEC 1993). We can supply fabrics suitable for a whole manner of purposes, from from 65gsm to 1200gsm in a large range of strengths and roll sizes. Fabrics can be coloured and engineered so that the UV resistance is extended beyond the standard 15 days should any fabric be exposed for prolonged periods. 40 P P X P O LYP R O P YLE N E G E O TE X
