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, preventing bentonite particles from flowing in one direction. When encountering water, a uniform high-density adhesive waterproof layer is formed inside the pad, effectively preventing water leakage.

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 permanent 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 the shortest construction period among existing waterproof materials.

Not affected by temperature

It will not break under cold weather conditions.

integrated

Integration of waterproof materials and objects: Sodium based bentonite has an expansion capacity of 20-28 times when it comes into contact with water. Even if the concrete structure vibrates and settles, the bentonite in GCL can repair cracks on the concrete surface within 2mm.

Green and environmentally friendly

Bentonite is a natural inorganic material that is harmless and non-toxic to the human body, has no significant impact on the environment, and has good environmental performance.

Product Features

High cost performance ratio, with a wide range of applications. The product has a range of up to 6 meters, greatly improving construction efficiency.

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

Construction can still be carried out at negative temperatures (-20 ℃) where traditional waterproof materials cannot be used; Construction can also be carried out on damp substrates (without visible water); Construction cannot be carried out in rainy or snowy weather; Not suitable for anti-seepage of strong acid and strong alkaline solutions; Due to its inorganic nature, bentonite has better durability than organic waterproof materials.
