Geosynthetic Clay Liner

Geosynthetic Clay Liner

Geosynthetic Clay Liner (GLCs) is the high performance needle punched environmental reinforced composites which combines two durable geotextile outer layers with a uniform core of natural sodium bentonite clay to form a hydraulic barrier.  Geosynthetic clay liner is often mechanically held together by needling, stitching or chemical adhesives.

 Geosynthetic clay liners are widely used as a replacement for compacted clay liners. Upon hydration, the bentonite in the GCL can swell automatically to form a low permeability clay layer with the equivalent hydraulic protection of several feet of compacted clay when hydrated under confining load.  The geosynthetic clay liner can provide approximately the same hydraulic protection as compacted clay can. The excellent tensile and peel strength properties make the geosynthetic clay liner ideal for composite liner systems, landfill composite base liners and backfilled seepage control liners, etc.
