Bentonite Waterproof Blanket
Bentonite waterproof blanket is a geosynthetic material composed of bentonite, polymer fiber and geotextile.
Good water absorption and expansion performance, good water conductivity, corrosion resistance, aging resistance, etc.
Bentonite waterproof blanket
Features:
1. High liquid adsorption capacity: Bentonite has good adsorption properties and can quickly absorb and lock liquid to form a waterproof layer.
2. Strong anti-permeability: Bentonite has a low permeability coefficient, which can effectively prevent the penetration of water and protect buildings and soil.
3. Good corrosion resistance: Bentonite is resistant to corrosion to a variety of chemical substances and can maintain stability under different environmental conditions.
4. Environmentally friendly: Bentonite waterproof blankets are made of non-toxic and harmless materials and have no pollution to the environment.
Application:
1. Basement waterproofing: It can be used as a waterproof layer in the basement to protect the concrete structure from water and moisture.
2. Roof waterproofing: It can be used as a roof waterproofing layer to prevent rainwater from penetrating into the building and protect the roof structure.
3. Basic engineering: It can be used in basic engineering such as building foundations, underground pipes, tunnels, etc. to play an anti-seepage and protective role.
4. Sewage treatment: It can be used in sewage treatment projects such as landfills, waste treatment plants, sewage treatment plants, etc. to prevent sewage leakage.
