The characteristics of Geosynthetic clay liner(GCL)

The characteristics of Geosynthetic clay liner(GCL)

1. Denseness of GCL: Sodium-based bentonite forms a high-density diaphragm under water pressure. When the thickness is about 3mm, its water permeability is α× 10-11m / sec or less, which is equivalent to 100 times the density of 30cm thick clay, has a strong self-water retention performance.

2. GCL has permanent waterproof performance: because sodium-based bentonite natural inorganic materials, even after a long time or changes in the surrounding environment, there will be no aging or corrosion, so the waterproof performance is long-lasting.

3. The construction of natural sodium GCL is simple and the construction period is 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 waterproof defects are found. GCL is a short construction period of existing waterproof materials.

4. The GCL is not affected by temperature: it will not be brittle under cold weather conditions.

5. Integration of natural sodium-based bentonite waterproof carpet materials and objects: sodium-based bentonite reacts with water and has an expansion capacity of 13-16 times. Even if the concrete structure vibrates and settles, the bentonite in the GCL can be repaired within 2mm Cracks on the concrete surface.

6. GCL is environmentally friendly: 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.
