Filter Point Concrete Linings with filtration points (drains) provide erosion-resistant, permeable concrete linings for ditches, channels, canals, streams, rivers, ponds, lakes, reservoirs, marinas, and protected port and harbor areas. Filter Point Concrete Linings have a cobbled surface and a relatively high coefficient of hydraulic friction in order to achieve lower flow velocities and to reduce wave run-up. The filtration points provide for the relief of hydrostatic uplift pressures, increasing the system’s stability.

Articulating Block Mats form cable-reinforced concrete block mattresses that resist erosive forces. They are often constructed where a revetment is exposed to frontal attack by wave action. AB Mats are typically used to protect coastlines, canals, rivers, lakes, reservoirs, underwater pipelines, bridge piers, and other marine structures from propeller wash, ship wakes, wind waves, currents, and high velocity flows. They are also used in environmental construction for landfill caps, down chutes, and collector channels.

Uniform Section (US) Concrete Linings are similar to traditional concrete slope paving.  They create a solid, high-quality concrete lining with a relatively low hydraulic resistance and uniform cross section.  These linings are used to reduce the infiltration or exfiltration of aggressive waste and chemical fluids into or out of open channels and basins.  They are also used to reduce exfiltration in arid regions where open channels and basins require watertight linings.

Filter Band (FB) Concrete Linings are similar to Filter Point, providing an effective and highly permeable concrete lining that resists erosive forces. Filter Band differs from Filter Point in that the form creates interconnected, tubular concrete elements that are separated by large, interwoven filtration bands.  The filtration bands provide for greater reduction of uplift pressures than Filter Point Linings.  Also, the biaxial alignment of the tubular elements creates two directionally determined coefficients of hydraulic friction.  As a result, Filter Band achieves greater reduction of flow velocity or wave energy than Filter Point.

Enviromat Concrete Linings are installed to provide protection against periodic high flows.  After installation, vegetation can be planted within the open structure of the lining to create a more natural appearance.  Enviromat Concrete Linings are used in drainage ditches and on the upper slopes of channels, canals, lakes, reservoirs, rivers, and other water courses as well as for embankments subject to heavy run-off.

Synthetex specializes in manufacturing engineered, project-specific fabric formworks for the casting-in-place of concrete armor units and structures for a spectrum of underwater applications.  For more than 25 years, engineering, contractor and government clients around the world have relied on HYDROCAST to design and fabricate the special concrete formworks they need for their projects.  They know Synthetex will deliver only the highest quality products, materials and workmanship—guaranteed.

The effect of the marine environment on structural materials can be harsh and unforgiving.  The service life and structural capacity of elements composed of reinforced concrete, structural steel, timber, and composites are affected by spaling, rust and hostel marine environments.

Synthetex installs fabric formed concrete supports, mattresses, covers, sleeves and shells to prevent pipeline damage and scour, and support pipeline freespans.  Jack-up supports can be used to raise a pipeline or structure.  The flexible, high-strength synthetic woven fabric bags are cost effective to make and are easy to deploy by an ROV or diver.

Synthetex’s HYDROTEX® Grout (concrete) Bags (GB) and tubes are an economical and convenient choice for applications requiring concrete, grout or sand filling.  Constructed of the high-strength polyester fabrics and using a heavy-duty sewing process, our bags are ready to perform in your most demanding construction or repair installations.  The custom designed bag is available in a variety of materials and a wide assortment of dimensions, porosities, volume capacity, and filling valve types that ensure compatibility with your applications.  Their flexibility and size makes them ideal for installation through confined spaces.
