Green and Environmentally Friendly Bentonite Geosynthetic Clay Liner for Pools and Underground Parking Lots
Product Introduction
Geosynthetic Clay Liner (GCL) is a special geosynthetic material designed for leak prevention. It is widely used in artificial lakes and water features, landfills, underground parking lots, rooftop gardens, pools, oil depots, and chemical storage yards.
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
The application field of bentonite waterproof blanket is very extensive, including but not limited to artificial lakes, landfills, artificial water systems, landscape lakes, landscape water belts, garage roof slabs, basements, reservoirs, river channel management and other projects.
