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