Bentonite Geosynthetic Clay Liner For River And Lake Seepage Prevention
Product Introduction
Sodium bentonite waterproof blanket (GCL) is an efficient and environmentally friendly waterproof material, which is widely used in various projects. Sodium bentonite absorbs five times its own weight of water when it meets water, and its volume expands to more than 15-17 times that of the original, forming a high-density diaphragm and having strong self-water retention performance.
Product Properties
1. Waterproof performance: Sodium bentonite waterproof blanket has excellent waterproof and impermeable properties.
2. Environmental protection: harmless and non-toxic to the human body, friendly to the environment, with good environmental performance.
3. Easy construction: The construction is relatively simple, does not need to heat and paste, just use bentonite powder and nails, washers, etc., to connect and fix.
4. Durability: Since sodium bentonite is a natural inorganic material, it does not undergo aging reaction, so it has long-term durability.
Product Application
1. Municipal works: such as subways, underground works of buildings and seepage prevention of roof reservoirs.
2. Environmental protection and sanitation: domestic waste landfills, sewage treatment sites, industrial waste seepage prevention.
3. Water conservancy project: river, lake and reservoir dam seepage prevention, plugging, reinforcement.
4. Garden landscape: such as artificial lakes, golf course ponds seepage prevention.
5. Other fields: petrochemical, mining, agriculture and other fields of engineering seepage prevention, corrosion prevention, leak prevention, reinforcement, etc.
