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 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.
Available in panels and rolls up to 2,250 square feet.
