Bentonite waterproof blanket is a geosynthetic material specially used for preventing leakage in artificial lake landscapes, landfills, underground garages, rooftop gardens, water pools, oil depots, and chemical storage yards. It is filled with highly expansive 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. The bentonite particles cannot flow in one direction and form a uniform high-density adhesive waterproof layer inside the pad when encountering water, effectively preventing water leakage.

Waterproof features:

Compactness

Sodium based bentonite forms a high-density diaphragm under water pressure. When the thickness is about 3mm, its permeability is less than&× 10 ˉ 11m/sec, which is equivalent to 100 times the compactness of 30cm thick clay, and it has strong self protective water performance.

Has long-lasting waterproof performance

Because sodium based bentonite is a natural inorganic material, even after a long period of time or changes in the surrounding environment, it will not undergo aging or corrosion, resulting in long-lasting waterproof performance.

Easy construction and short construction period

Compared with other waterproof materials, the construction is relatively simple and does not require heating or pasting. Just use bentonite powder and nails, washers, etc. for connection and fixation. No special inspection is required after construction, and if waterproof defects are found, they are also easy to repair. GCL has a shorter construction period among existing waterproof materials.

Not affected by temperature

It will not break under cold weather conditions.

Scope and application conditions: Suitable for municipal (landfill), water conservancy, environmental protection, artificial lakes, and underground waterproofing and anti-seepage engineering of buildings.
