Three Layers--
Woven geotextile:protecting and strengthen to ensure shearing strength and tensile strength
Non-woven geotextile:protecting and strengthen to ensure shearing strength and tensile strength
Bentonite clay:Natural sodium bentonite clay
Characteristic of GCL--
A: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.
B: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.
C:GCL is nature inorganic material, which is non-poisonous and harmless to human body, so it is environment protection material.
Application Filed of GCL--
· Water storage, miniature reservoir, dam of reservoir, acequia,fish pond
· Roof garden, basement etc.
· Subway, railway, expressway, light industry, oil and metallurgy and other industry
· Maintenance, repair and reinforcement of earth works
