Geocomposite Geosynthetic Clay Liner
Introduction of GCL:
Geosynthetic Clay Liner is manufactured by three levels, including two levels of geotextile whose functions are protecting and strengthen to ensure shearing strength and tensile strength, inner content is Sodium bentonite clay. It is manufactured by nature layer silicate inorganic materials and has high expansibility and high water-absorbing capacity, when soak with low permeable capability, whose the main function is anti-seepage.
Features 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
Environmental reform, garbage landfill, artificial lake or other landscape
