Description of Bentonite GCL
1 Bentonite GCL is self-attaching and self -sealing to concrete or other construction structures.
2 It is made of a non-woven geotextile, a natural sodic bentonite layer, with or without a pe geomembrane layer, and a polypropylene sheet.
3 These layers are connected with a dense felter that makes the bentonite a self-confinement with controlled expansion. With this system it is possible to avoid slippage and the accumulation of bentonite as a consequence of cuts, tears, vertical applications and movements.
What is the type of GCL-OF: The upper layer is woven geotextile, the bottom layer is membrane, the middle layers are the natural sodium bentonite clay and nonwoven geotextile.

Benifits of GCL:
Good Self Water-Retention Property:
Form high density diaphragm under hydraulic pressure, the water permeable capability
equals to 100 times density degree of 30cm clay when the thickness of GCL is 3mm. It
has very good self water-retention property.
Permanent Water Proofing Capability:
GCL is nature inorganic material, it won't aging or corrode even after long
time or surrounding changed, so it has permanent water proofing capability.
Environment-friendly:
GCL is nature inorganic material, which is non-poisonous and harmless to human body, as a result, it is eco-products.
