5m 5..5m 6m Width Gcl Geosynthetic Clay Liner Applying In Artificial Lake Irrigation Pond And Landfill Project
GCL Bentonite Waterproof Blanket
Our bentonite composite waterproof blanket has four layers which 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.
It is filled with high expansion sodium bentonite between special composite geotextile and non-woven fabric. The bentonite anti-seepage pad made by needling method can form many small fiber spaces.The special needling process is to make the coarse fiber pass through the bentonite from the upper geotextile and fix it on the lower geotextile. By combining the four parts, the integrity of the bentonite waterproof blanket is effectively enhanced, and the shear strength and tensile strength of the bentonite waterproof blanket are greatly enhanced, which makes the bentonite waterproof blanket can be used alone, It can also be combined with compacted clay impervious core or geomembrane.The bentonite particles can not flow in one direction, and even high-density colloidal waterproof layer is formed in the cushion when encountering water, which can effectively prevent water from leakage.
