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.
