It is composed of 3 levels. The upper level and the lower level are woven geotextile and non woven textile. 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).
Our GCL combines the two advantages together, not only containing all the properties of geotextile materials, but also bearing of double waterproof property.
