Specifications

GCLs ( ref JGCL and JSGCL) and composite GCLs with HDPE liners laminated onto the GCLs (our ref no. JHM-JCL & JHM-SGCL)

Bentonite Geosynthetic clay liners (GCL) consist of  bentonite, woven between two geotextile layers. This lining mechanism uses the properties of bentonite and the material to which it is bonded holds the clay in place.
GCLs require soil cover of at least 300mm to provide sufficient normal force to confine the expansion of the bentonite core layer. The bentonite swells and extrudes through the geotextile fabric at the overlap, forming a seal by producing a dense and uniform clay barrier with the same hydraulic qualities in all parts of the clay liner.

 

We have GCLs ( ref JGCL and JSGCL) and composite GCLs with HDPE liners laminated onto the GCLs (our ref no. JHM-JCL & JHM-SGCL)
