Bentonite geosynthetic clay liner

Sodium bentonite geosynthetic clay liner has capacity of saving moisture,its water absorption content and water content can reach over 10 times of own weight.

Geosynthetic clay liners (GCLs) combine geosynthetics with sodium bentonite clay to form a highly

impermeable barrier that often replaces thick layers of expensive compacted clay.

GCLs is composed of 3 layers, the upper layer is nonwoven geotextile, while the lower layer is woven geotextile,

natural sodium bentonite fills the gap between geotextile layers.

Waterproof characteristics
1) Density:Na-bentonite under water pressure form high density diaphragm, when the thickness about 3mm, its permeability coefficient is less than αx10-11 m/sec, is 100 times of 30cm of clay, has a strong self-protection properties of water.
2) Have a permanent water-proof performance:Because Na-bentonite base for natural inorganic materials, after a long time or a change in the environment, aging or corrosion does not occur, therefore, durable waterproof performance.
3) Simple operation, short construction period: Compare to other waterproof material, the construction is relatively simple and does not need heating and paste. Just need bentonite powder and nails washers for connect fixed etc.
4) From the effects of temperature: In the cold weather will not be brittle fracture.
5) Waterproof materials and the target of integration: Na-bentonite and water reaction, with 13-16 times expansion capacity, even if the concrete structure vibration and settlement occurred, bentonite in GCL can repaire within 2mm concrete surface cracks.
6) Green environmental protection: Bentonite for natural inorganic materials, non-toxic harmless to humans, does not effect to the environment, has a good environmental performance
