Chemical Storage Yard Seepage Control Isolation China Wholesale Price Geosynthetic Clay Liner Blanket 55×6 GCL
Quick Detail:
component: geotextile, bentonite and (HDPE) geomembrane fibers
size: 55*6m
function: isolation, seepage control
application: chemical storage yard, chemical plant
Product Description:
FUYUN GCL (bentonite waterproof geosynthetic clay liners) also named bentonite composite waterproof blanket or pad has four layers:
1.The upper and lower layers are geotextiles, which mainly play the role of protection and reinforcement, so that it has a certain overall puncture strength and tensile strength;
2.The middle layer is sodium bentonite, which is made of natural clay mineral inorganic materials. It has high expansibility and high water absorption capacity, and low water permeability when wet;
3.The bottom layer is a thin HDPE geomembrane, which is mainly used for anti-seepage.
FUYUN GCL 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.
FUYUN GCL can be constructed under the negative temperature (-20℃), while the traditional waterproof material cannot, because bentonite is inorganic material having better durability than that of organic waterproof material.

Application:
Installing Note:
1, Before GCL 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.
Advantage:
- The seepage resistance is better than bentonite, and can stop water with water, and has high hydrostatic pressure resistance.
-
Bentonite is a kind of natural inorganic material, which has no aging reaction and good durability.
-
It belongs to environmental protection material and will not cause any adverse impact on the environment,It is buried underground, and has no pollution to water quality and soil.
-
It has the advantages of simple construction, low requirement for base course, natural overlapping and construction under sub zero temperature.
-
In the construction of elevation or inclined plane, fix it with nails and washers, and lap it as required.
-
The unique self-healing property makes use of the swelling property of bentonite when it meets with water, which can self heal and repair the defect or damage of impervious layer.
-
It is easy to repair. Even after the completion of waterproof Engineering (anti-seepage engineering), if the waterproof layer is accidentally damaged, as long as the damaged parts are simply repaired, the perfect waterproof performance can be obtained.
-
The unique air permeability is conducive to the exchange of water and air, and makes the plants around the water grow healthily.
