Geosynthetic clay liner

Product description

Geosynthetic clay liner is a geosynthetic material specially used for anti-seepage of artificial lake water features, landfills, underground garages, roof gardens, pools, oil depots and chemical storage yards. It is made of highly expansive sodium Base bentonite is filled between the special composite geotextile and non-woven fabric, and the bentonite anti-seepage pad made by acupuncture method can form many small fiber spaces, because the bentonite particles cannot flow in one direction and form in the pad when they meet water Uniform high-density colloidal waterproof layer, effectively prevent water leakage.

Features

1. Compactness

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

2. Permanent waterproof performance

Because sodium bentonite is a natural inorganic material, even after a long time or changes in the surrounding environment, it will not age or corrode, so the waterproof performance is durable.

3. Simple construction and short construction period

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

4. Not affected by temperature

It is also not brittle in cold climates.

5. Integration

Integration of waterproof materials and objects: When sodium-based bentonite meets water, it has an expansion capacity of 20-28 times. Even if the concrete structure vibrates and settles, the bentonite in GCL can also repair cracks on the concrete surface within 2mm.

6. 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.

Application range

It is suitable for municipal (garbage landfill), water conservancy, environmental protection, artificial lakes and underground waterproofing and anti-seepage projects of buildings.
