Customized Size Geosynthetic Clay Liner GCL Bentonite Clay Liner For Landfill Project Irrigation Systerm Etc
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.
Product is filled with high expansion sodium bentonite between special composite geotextile and non-woven fabric. The bentonite anti-seepage mat is 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 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.

(1) A permanent waterproof performance, and excellent water seepage performance, impermeability hydrostatic pressure up
to 1.0MPa above, permeability coefficient 5 *10-9cm / s.
(2) Has all the characteristics of geotextile material, such as separation, reinforcement, protection, filtration, simple construction and unrestricted construction environment temperature below 0 0 C also be construction.
(3) Easy to repair; Even after water (seepage) end of construction, such as waterproof layer accident damage, as long as the site of the damage to be a simple fix, can ever regain perfect waterproof performance.
(4)green: Bentonite is a natural inorganic material, harmless, non-toxic,no particular impact on the environment, with good environmental performance.
(5) simple construction period is short: and other waterproof materials, the construction is relatively simple, does not require heating and paste.
(6) Integrated waterproof materials and objects: When sodium bentonite water, with 20-28 times the capacity expansion, even if the concrete structure vibration and settlement, bentonite GCL can repair cracks in the concrete surface less than 2mm.
products will be well woven and belt packed, and we gurantee the product good before the customer receive. Besides, products can be packed as customer's special requirement.
