Use of geotextiles in Roads & Railways is one of the most common applications of geotextiles. The pumping effect generated by traffic passing can cause a fast deterioration of the ballast and granular support of those to sleepers and asphalt or concrete. High strength nonwoven or woven geotextiles can offer an excellent solution to avoid these failures.
In urban areas can geotextiles be found in most diverse applications. The geotextiles are being used in access and paved roads, sport fields, riverbed protection, drainage trenches and pond liner protection. The geotextiles are also being used in vertical drainage applications. Groundwater and excess rainwater can be controlled well when geotextiles are properly used. More and more floods cause serious damage to urban areas.

TenCate geosynthetics enhance the performance and the design life of railway construction structures. For these applications, a TenCate geosynthetic is installed as separation and filter layers in areas where groundwater is a problem. TenCate geosynthetics offer the ideal characteristics of robust mechanical properties coupled with high water flow capabilities.
Geotextile provides inherently stronger track system that lasts longer, requires little maintenance, and produces a net cost savings. For new track or repairs, there's no need to remove native soil, install our product directly on the subgrade and eliminate contamination from below the ballast.
The geotextile performs two primary functions when used in the construction of tunnels:-
1. Protection of the linear from abrasion and puncture by protrusions from the base surface of the tunnel well.
2.Drainage of water seeping through the rock and sprayed concrete layer. The in-plane oermeability of the geotextile enables the water to flow to a subsurface drainage collection system. where it is directed awa from the tunne
Quicker, easier, safer transportation means are required. Depending on geographical zones, tunnels can be a must to reach your final destination easily. Decades of experience in tunnel constructions with TenCate Polyfelt P have shown that protection geotextiles replaces the need for drainage material around the tunnel lining.
Geosynthetics offer cost-effective, long-term solutions where conditions impose severe restrictions on road construction - where subsoils are poorly drained, or where the subgrade consists of cohesive, saturated and/or organic soil. Geosynthetics have also radically changed the way embankments, retaining walls, steep slopes, and even tunnels and bridges are constructed.
TenCate Geosynthetics deliver solutions that enhance the performance and design life of transportation engineering structures for paving. From our complete product line for Roadway and Railway Construction System Solutions, we offer materials that function for sealing, stress relief, adhesive bonding, and soil reinforcement. They offer robust mechanical properties coupled with high water flow capabilities that extend pavement life by retarding reflective cracking, waterproofing and reinforcing asphalt pavements.
Tidal fluctuations and wave action can cause major damage to coastlines and off-shore construction projects. Nonwoven and specialty woven geotextiles can be used as a filter under layer beneath stone/ rock armour. Also riprap or synthetic erosion control mats are used to control erosion by disallowing the sub grade soil particles to erode. The geotextiles prevent erosion carried off by runoff water or other erosive waters, such as waves, stream flow, etc.
Water is irreplaceable for life and for a great many businesses. It is a guarantee of survival and a scarce resource. Today`s society demands increasingly large volumes of increasingly high-quality water. TenCate Geosyntehtics has had a constant hand in the creation of water management infrastructure. In the last 20 years it has built more than 30 dams of a wide range of types and has used for that purpose the most modern of construction systems. TenCate filtration systems offer optimized hydraulic properties...
In infrastructure projects in which space has to be saved or land acquisition minimized, TenCate Geosynthetic soil reinforcement technology has been used in the design and construction of steep slopes or walls. The use of this technology increases the stability of such structures.
The world registers less than 3.5 million kms of pipelines in 120 countries. Pipelines conveying flammable or explosive material, such as natural gas or oil, pose special safety concerns. To avoid pipeline instability and damage caused by differential settlements, TenCate Geosynthetics EMEA offers you the optimum solution from its wide range of reinforcement geosynthetics: TenCate Geolon PET & PP, TenCate Miragrid GX & TenCate Rock PEC ranges.
Polymeric liners are prone to puncture by inclusions within the underlying soil. Thick, non-woven geotextile can be used to give protection to liners during installation.
Often the upper slopes are exposed to damage and it is a good practice to cover these areas with a depth of soil which will sustain vegetation. Alternatively, a stone or concrete substance can be used to achieve a hard landscaped appearance. Our product will protect the liner from puncture whilst also providing a degree of slope stability.
Geotextiles enhance both drainage and lining systems in environmental applications. In the large industry of waste containment, geotextiles are used to protect and cushion landfill liners and landfill capping systems, and they are used as critical components of geocomposites such as geocomposite drains and geosynthetic clay liners. Heavyweight, needle-punched nonwovens are use as cushion/protection for landfill and pond liners to keep adjacent stones in overlying or underlying drainage layers from puncturing the...
Historically, landfills have been the most common method of organized waste disposal and remain so in many places around the world. Landfills are essential applications to ensure long service life and prevent soil pollution. In industrial basins, TenCate protection geotextiles guarantee the protection of the geomembrane against all risks of mechanical damages. A cost effective and environmental friendly solution to sort, treat and recycle waste.
Dragflow dredging equipments are widely used in underwater excavation and dredging activities. Dragflow pumps are design to work both in shallow seas, or fresh water areas, as well as in deep water applications. The unique design of dredging cutters allows Dragflow equipments to reach an exceptional solid concentration also in presence of very compact soil.
