Product Description
The GCL is punched together with non-woven geotextile, woven geotextile and bentonite. Width of the geosynthetic clay liners can be up to 6m and length of 60m. The middle level is bentonite grains, which are carefully selected crude and filled in between the two levels after special processing. The bentonite grain in GCL made by this method does not flow in a fixed direction. It distributes evenly and forms waterproof layer, owning excellent waterproof effect. This GCL is a kind of new green waterproof materials, which are widely applied in many waterproof construction projects. GCL can be applied separately, or combined with high density polyethylene (HDPE).
