Product Description

Reinforced Geotextile Bentonite Geomembrane Geosynthetic Clay Liner Waterproof Pad

Product Description:

Geosynthetic clay liner (GCL) is composed of high dilatability of sodium base bentonite filling between the special composite geotextile and nonwoven fabric. It made by the method of acupuncture or suture composite impervious material. Use acupuncture into GCL can form many small fiber space, make the bentonite particles can't flow in one direction, when under the influence of water within the mat forming uniform density of colloidal waterproof layer, prevent the leakage of water.
For different projects, it can combine HDPE liner for better waterproof. Bentonite has the expansion of the water characteristics. General calcium base bentonite expands, its expansion is only about 3 times their own size; And sodium base bentonite adsorption 5 times its own weight of water in case of water, Volume expansion to the original 15 to 17 times above; The geotextile and nonwoven fabric lock sodium base bentonite in the middle of the two layers of geosynthetic materials, play a protecting and strengthening role , make the GCL has a certain overall shear strength.
