Fabric Formed Concrete Solutions

Fabric Formed Concrete Linings are used to construct a wide range of engineering systems to provide maximized performance in erosion control, scour protection, foundation, environmental, and marine construction applications.

Fabric Formed Concrete is a highly engineered textile that can be made into custom panel sections and patterns. The custom mattresses are then pumped full of high-strength flow-able concrete grout that sets up into a uniformly patterned concrete liner system.

Fabric Formed Concrete Linings are resistant to industrial leachates and most chemicals. They protect geosynthetic liner systems from mechanical damage, exposure to UV light, and freeze-thaw cycles. These self-supporting, high-strength linings permit construction on steep side slopes and replace the conventional use of clay or sand as liner protection. Placement of forms and concrete filling can be done without the use of equipment on the liner.

The tensile strength and abrasion resistance of the fabric protect the liner from the pumped concrete.

Uniform Section (US) Concrete Linings

Uniform Section (US) Concrete Linings are similar to traditional concrete slope paving. They create a solid, high-quality concrete lining with a 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 Point (FP)

Filter Point Fabric Formed 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 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.

Filter Band (FB)

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.
