Geosynthetic Clay Liners

Geosynthetic Clay Liners Waterproof features:
1.Compactness
Sodium-based bentonite forms a high-density diaphragm under the condition of water pressure. When the thickness is about 3mm, its water permeability is less than & × 10ˉ11m / sec, which is equivalent to 100 times the compactness of 30cm thick clay. It has strong self-water retention performance. .
2.Permanent waterproof performance
Because sodium-based bentonite is a natural inorganic material, even after a long period of time or the surrounding environment changes, aging or corrosion will not occur, 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. Just connect and fix with bentonite powder and nails, washers, etc. No special inspection is required after construction, and it is easy to repair if water-proof defects are found. GCL is the shortest construction period of existing waterproof materials.
4. Not affected by temperature
It is not brittle in cold climates.
5. Integration
Integration of waterproof material and object: Sodium-based bentonite has an expansion capacity of 20-28 times when it encounters water. Even if the concrete structure vibrates and subsides, the bentonite in GCL can repair cracks on the concrete surface within 2mm.
6. Green environmental protection
Bentonite is a natural inorganic material, which is harmless and non-toxic to the human body, has no special impact on the environment, and has good environmental performance.

Geosynthetic Clay Liners Features:
The cost performance is high and the application is very wide. The product width can reach 6 meters, which greatly improves the construction efficiency.
Scope and application conditions: Suitable for municipal (garbage landfill), water conservancy, environmental protection, artificial lake and building underground waterproof and anti-seepage projects.

It can still be used at negative temperatures (-20 ° C) where traditional waterproofing materials cannot be used; it can also be used on wet bases (no clear water); it cannot be used in rainy or snowy weather; it is not suitable for strong acid and alkaline solutions Infiltration; because of bentonite-based inorganic materials, its durability is better than organic waterproof materials.
