6m*50m, 5m*50m Three Layer Four Layer Geosynthetic Lay Liner GCL Bentonite With Antiseepage Function
Geosynthetic Clay Liner
Our GCL bentonite composite waterproof blanket/ pad has four layers which is composed of high dilatability of sodium base bentonite filling between the special composite geotextile and nonwoven fabric. Product is 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.

Installing Note:
1, Before GCL bentonite clay liner construction, foundation
should be inspected, the foundation should be rammed flat, no
potholes or water, no gravel or roots or other sharp objects.
2, In the process of handling and construction, GCL should be to
avoid vibration and impact, to avoid large degree of bending.
3. After installing and acceptance of GCL, backfill shall be
carried out as soon as possible. If it is in conjunction with the
use of HDPE geomemes, geomemes shall be installed and welded in
time to prevent them from being wet or broken by rain.
