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.
