The Geosynthetics Clay Liner is a kind of geosynthetic material specially used for anti-seepage of artificial lakes, waterscapes, landfills, underground garages, roof gardens, pools, oil depots and chemical storage yards. 

It is made of highly expansive sodium-based bentonite is filled between the special composite woven geotextile and non-woven geotextile. The bentonite impermeable pad made by needle punching can form many small fiber spaces. 

The bentonite particles cannot flow in one direction, and they stay in the pad when it meets water. A uniform and high-density colloidal waterproof layer is formed to effectively prevent water leakage. 

Performance feature:

1.Compactness:Sodium bentonite forms a high-density diaphragm under water pressure. When the thickness is about 3mm, its water permeability is less than &×10ˉ11m/sec, which is equivalent to 100 times the density of 30cm thick clay, 

and has strong self-water retention performance.
2. Excellent 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 long-lasting.
3.Simple construction and short construction period - Compared with other waterproof materials, the construction is relatively simple and does not require heating and pasting. Only bentonite powder, nails, washers, etc. are needed for connection and fixing. No special inspection is required after construction, and it is easy to repair if waterproof defects are found.

4.Not affected by temperature - it will not break brittlely under cold climate conditions.
5. Integration:Integration of waterproof materials and objects: Sodium bentonite has an expansion capacity of 20-28 times when it meets water. Even if the concrete structure vibrates and settles, the bentonite in the GCL can repair cracks on the concrete surface within 2mm.
6. Green and environmentally friendly - 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.
7. High performance-price ratio, very wide range of uses. The product range can reach 6 meters, greatly improving construction efficiency.

Application: 

1. Used to stabilize road and railway subgrades. 

2. The waterproof of municipal engineering, underground engineering of subways, buildings and roof reservoirs. 

3. Environmental protection and sanitation, domestic waste landfill, sewage treatment plant, industrial waste. 

4. Water conservancy, seepage prevention, plugging and reinforcement of rivers, lakes, reservoirs and dams. 

5. Waterproof of ponds in gardens, artificial lakes, golf courses, etc. 

6. Waterproof, anti-corrosion, anti-leakage, reinforcement, etc. in petrochemical, mining, agricultural and other fields.
