GCL Bentonite Geotextile Mat Waterproof Blanket Geosynthetic Clay Liner

1.The permanent waterproof

No happen aging or corrosion phenomena, so the waterproof performance persistence.
2. Compactibility

Sodium base bentonite under water pressure condition to form diaphragm with high density, thickness of about 3 mm

3. Not affected by temperature

In cold climates will not brittle fracture.

4.Environmental protection

Bentonite as natural inorganic material,no special effects to the environment, have good environmental performance.

5.Simple construction

Construction is relatively simple, don't need to be heated and paste. With bentonite powder and nails, washers, etc are connected and fixed.

Product Description

Products 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.
