Bentonite waterproof blanket

Swelling waterproof blanket is a kind of anti-seepage geosynthetics specially used for artificial lake water features, landfill sites, underground garages, roof gardens, pools, oil depots and chemical yards, etc. It is filled by high swelling sodium bentonite between special composite geotextiles and non-woven fabrics, and the bentonite anti-seepage pad formed by needling method can form many small fiber Spaces. So that the bentonite particles can not flow in one direction, when the water in the pad to form a uniform high density of rubber waterproof layer, effectively prevent water leakage.

Waterproof feature

compactness

Sodium bentonite forms a high-density diaphragm under water pressure. When the thickness is about 3mm, its water permeability is &×10ˉ11m/sec or less, which is equivalent to 100 times the compactness of 30cm thick clay, and has strong self-water retention performance.

It has permanent water resistance

Because sodium bentonite is a natural inorganic material, even after a long time or changes in the surrounding environment, there will be no aging or corrosion phenomenon, so the waterproof performance is durable.

Construction is simple and short

Compared with other waterproof materials, the construction is relatively simple and does not require heating and pasting. Just use bentonite powder and nails, washers, etc. to connect and fix. No special inspection is required after construction, and it is easy to repair if waterproofing defects are found. GCL is the shortest construction period of existing waterproof materials.

Not affected by temperature

It will not be brittle in cold climates.

integration

The integration of waterproof materials and objects: When sodium bentonite meets water, it has 20-28 times the expansion capacity, and even if the concrete structure is shaken and settlement, the bentonite in GCL can repair cracks on the concrete surface within 2mm.

Green and environmental protection

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

Product characteristics

The performance cost is high, and the use is very wide. The product range can reach 6 meters, which greatly improves the construction efficiency.

Application scope and application conditions: Suitable for municipal (landfill), water conservancy, environmental protection, artificial lake and building underground waterproof, seepage prevention projects.

It can still be constructed under negative temperature (-20℃) where traditional waterproof materials cannot be constructed; It can also be constructed on the wet base (without open water); No construction in rain or snow; Not suitable for strong acid, strong alkaline solution impermeability; Because bentonite is an inorganic material, its durability is better than that of organic waterproof material.
