Green and Environmental Protection Bentonite Geosynthetic Clay Liner for Easy and Short Duration Construction
Product Introduction
The bentonite waterproof blanket is filled between a specially made composite geotextile and a non-woven fabric with highly expansive sodium bentonite. The bentonite impermeable mat made by needling method can form many small fibered manifold, is the bentonite particles can not flow like a direction, in case of water in the cushion to form a uniform high-density gel waterproof layer, effectively prevent water leakage.
Features
-
Density: Sodium-based bentonite forms a high-density diaphragm under water pressure, with an extremely strong self-water retention property.
-
Permanent Waterproofing: Sodium bentonite is a natural inorganic material that does not experience aging or corrosion due to long-term use or environmental changes.
-
Easy Construction and Short Duration: The construction process is straightforward, requiring no heating or adhesives. Instead, bentonite powder is used in conjunction with nails and washers for connection and fixation. There is no need for special inspection after construction, and repairs are easy to carry out.
-
Temperature-independent: Will not experience brittleness or other phenomena even in cold weather.
-
Integration: The waterproof material is integrated with the waterproof object. When sodium-based bentonite encounters water, it has the ability to expand by 20 to 28 times, capable of repairing tiny cracks on the surface of concrete.
-
Green and Environmental Protection: Bentonite is a natural inorganic material that is harmless to human health and has little impact on the environment.
Product Application
Mainly used in environmental engineering constructions, such as waste landfill, underground reservoir, underground infrastructure construction projects, to solve the seal, isolation, seepage control and related problems, good effects and strong destruction resistance.
