Product Description

Product Description

Denseness - Sodium based bentonite forms a high-density diaphragm under water pressure, with a thickness of about 3mm. Its permeability is equivalent to 100 times the compactness of 30cm thick clay, and it has strong self water retention performance.

Waterproof performance - Because sodium based bentonite is a natural inorganic material, even if the surrounding environment changes over a long period of time, it will not age or corrode, resulting in long-lasting anti-seepage performance.

Short construction period - Compared with other waterproof materials, the construction is relatively simple and does not require heating and pasting. Only bentonite powder and nails, washers, etc. are needed for connection and fixation. After construction, there is no need for special inspection. If waterproof defects are found, they are also easy to repair. GCL is the shortest construction period among existing waterproof materials.

Green and environmentally friendly - Bentonite is a natural inorganic material that is non-toxic and harmless to the body, and has no special impact on the environment. It has good environmental performance

Installation Instructions

Bentonite waterproof blanket is a geosynthetic material specifically used for preventing leakage in artificial lakes, landfills, underground garages, rooftop gardens, water tanks, oil depots, and chemical storage yards. It is filled with high expansion sodium based bentonite between specially made composite geotextiles and non-woven fabrics. The bentonite anti-seepage pad made by needle punching method can form many small fiber spaces, and the bentonite particles cannot flow in one direction. When encountering water, it forms a uniform high-density gel like waterproof layer inside the pad, effectively preventing water leakage.
