Geosynthetic Clay Liners or GCLs are geotextile and bentonite composites made of sodium bentonite sandwiched between two layers of geotextile and engineered for a variety of environmental containment applications. The geotextiles offer a long-lasting resistance to physical or chemical break-down in harsh elements, and the bentonite’s high swelling capacity and low permeability provide an effective hydraulic seal.
– GCLs are a low-cost replacement for compacted clay soil.
– GCLs are quicker to install, even when the clay is available on site.
– When the GCLs are hydrated under confinement, the bentonite in it swells to make a low permeability layer of clay with appropriate hydraulic protection to that of several feet of compacted clay.
1.Excavate your area for lining
2.Prepare the area for liner installation
3.Install the geosynthetic clay liners.
1. Poor water retention capacity in soils.
2. Hazardous material, solid waste from livestock, and petroleum product penetrations.
3. Contamination of soil by hazardous materials.
4. Air/gas trapped under the liner from geothermic activity can be released, unlike traditional liners.
5. GCLs have a swell index compared to other clays, if it is punctured it will self-seal any holes, punctures, or tears in the liners.
