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 no aging or corrode even after longtime or surrounding changed, permanent water proofing capability.

C: nature inorganic material, non-poisonous and harmless to human being

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
