Linings are essentially used to function as barrier system to liquids.Typical applications for linings can be found in solid waste landfills, ponds, canals and building sites infrastructures. TenCate Geosynthetics solutions for lining are namely geosynthetic clay liners (GCL) and concrete mattress systems.

GCL's are commonly used to line the base of landfills as a barrier system to liquids. With the implementation of environmental legislations, seepage from landfills must be collected and disposed of appropriately to prevent contamination of ground water. Due to its low hydraulic conductivity and stability in structure, TenCate Enviromat® GCL’s work effectively as a barrier layer in limiting the seepage of liquids, leachates and gases out of landfills. When installed on slopes, Enviromat® GCL’s exhibit good internal shear resistance even at large shear strains. The upper and bottom geotextile layers of Enviromat® GCL’s also interact with the soil to provide external shear resistance to ensure the soil overburden does not slide over the GCL surface while the GCL itself does not slide over the foundation slope surface.

To reduce flooding and erosion problems, detention ponds are included as a solution in stormwater management. Enviromat® GCL’s are commonly applied as a base liner in these detention ponds to effectively prevent water leakage from the base and sides of the ponds. Enviromat® GCL’s are also used in landscape and recreational ponds, golf course ponds, dams, reservoirs, canals and other water impoundments for the same function. An additional option for lining of water impoundments is the Geotube® Concrete Mattress which offers a hard durable surface as the mattress is filled with cement mortar.
