GCL - GEOSYNTHETIC  CLAY LINER

Geomembrane Liners, Geotextiles, Geocomposites, Geogrids, Cellular Confinement Systems, Geonets, Geosynthetic Clay Liners, Pond Liners

Geosynthetic Clay Liner (GCL) serves as a hydraulic barrier by combining bentonite clay with layers of geotextile and in some cases, geomembrane liner. GCL can be used as a stand alone alternative for a compacted clay liner, or as a supplement to a geomembrane liner system.  Its low permiability and high shear strength provide long lasting resistance under harsh conditions. 

GCL APPLICATIONS:

Landfill Liners

Landfill Caps

Mining

Secondary Containment

Ponds

INSTALLATION 

GCL can be quickly and efficiently installed further contributing to its low cost compared to compacted clay liner.  Rolls are depolyed using a spreader bar attached to a piece of equipment such as a front end loader or extendable boom forklift. Loose bentonite is then placed under the overlap effectively seaming the liner. 

Deployed GCL must be covered with soil as soon as possible to avoid premature hydration of the bentonite.
