Product Description

Products Description


Geosynthetic clay liner (GCL) is composed of high dilatability of sodium base bentonite filling between the special composite geotextile and nonwoven fabric. It made by the method of acupuncture or suture composite impervious material. Use acupuncture into GCL can form many small fiber space, make the bentonite particles can't flow in one direction, when under the influence of water within the mat forming uniform density of colloidal waterproof layer, prevent the leakage of water.
For different projects, it can combine HDPE liner for better waterproof. Bentonite has the expansion of the water characteristics. General calcium base bentonite expands, its expansion is only about 3 times their own size; And sodium base bentonite adsorption 5 times its own weight of water in case of water, Volume expansion to the original 15 to 17 times above; The geotextile and nonwoven fabric lock sodium base bentonite in the middle of the two layers of geosynthetic materials, play a protecting and strengthening role , make the GCL has a certain overall shear strength.

GCL Features

1.The permanent waterproof
No happen aging or corrosion phenomena, so the waterproof performance persistence.
2. Compactibility
Sodium base bentonite under water pressure condition to form diaphragm with high density, thickness of about 3 mm
3. Not affected by temperature
In cold climates will not brittle fracture.
4.Environmental protection
Bentonite as natural inorganic material,no special effects to the environment,  have good environmental performance.
5.Simple construction

Construction is relatively simple, don't need to be heated and paste. With bentonite powder and nails, washers, etc are connected and fixed.


Application Scenarios

1. The landfill anti-seepage closed treatment engineering.

2. The waterscape engineering and artificial landscape engineering.
3. The underground tank seepage control engineering.
4. Channel, the canal seepage control engineering.
5. The reservoir seepage control engineering (pool).
6. The subway engineering.
7. The tunnel engineering.

8. The underground structure and waterproof engineering such as underground foundation.


GCL Production Advantages

1. Improved leakage performance. 2. Permanent waterproof performance.
3. Simple construction and the short time limit for a project.
4. Not influenced by the air temperature.
5. A kind of green material and good to environmental protection. 6. More versatile than compacted clay.
7. Increased airspace and liner efficiency.
