Geosynthetic Clay Liner
Geosynthetic Clay Liners (GCL) are high performance geocomposites that are used as an alternative to conventional compacted clay liners. GCLs consist of two layers of geotextile carriers such as woven and/or non-woven which are stitched together enclosing a layer of processed sodium bentonite. Bentonite is a natural sealant, and when in contact with water, swells to form a low permeability clay liner. Geosynthetic clay liners have a long lasting resistance to physical and chemical break-down in harsh environments such as landfills and other containment systems.Just one truckload of GCL replaces 200 truckloads of clay.
Available Geosynthetic Clay Liners:
♦ Geomembrane Supported
♦ Fabric Encased
