GCL Geosynthetics Clay Liner

Geosynthetic clay liners (GCLs) are gecomposites that are prefabricated with a bentonite clay layer typically incorporated between a top and bottom geotextile layer or geotextile bentonite bonded to a geomembrane or single layer of geotextile.

 Geotextile-encased GCLs are often stitched or needle punched through the bentonite core to increase internal shear resistance. When hydrated they are effective as a barrier for liquid or gas and are commonly used in landfill liner applications often in conjunction with a geomembrane.
