Product Introduction

Bentonite geosynthetic clay layer is a new type of geotechnical synthetic material. It is a composite impervious material made of a layer of clay or other low-permeability mineral material, outer membrane geotextile or geomembrane, which is made by needle punching or stitching. Our company uses high-expansion sodium bentonite, which is characterized by its expansion after water contact, resulting in hydration and the formation of a water-impermeable gel. This bentonite also has the ability to store water. Water up to 10 times its own weight.




Compared with geomembrane, its superiority is mainly manifested in:

a) Compact water-proof and waterproof performance, bentonite forms a solid water-impermeable gel membrane layer under normal water pressure

b) Good flexibility, can better adapt to uneven precipitation.

c) Long-term waterproof capacity, bentonite is natural inorganic mineral material, no corrosion and aging

d) The water absorption thickness increases several times, it is not easy to be broken, and it has self-repair ability even in the case of top break



It is mainly used in landfills, underground reservoirs, and underground infrastructure construction projects in environmental engineering to solve problems such as sealing, isolation, and leakage prevention, with good results and strong resistance to damage.



Construction method and attentions:

1. When laying sodium bentonite composite waterproof pad, usually put the non-woven (white) upward, woven cloth (black) towards down laying, or according to the design requirements, engineering requirements to lay.

2. When laying, it should avoid the raining day, if suddenly meet the rainy day, it should stop laying and covered with plastic film to prevent rain water intrusion and occur hydration.

3. Sodium bentonite composite waterproof pad construction should confirm water flow direction first, laying along the water flow direction, make the upstream waterproof gasket pressed on the downstream waterproof pad.

4. In the inclined surface and the slope construction, sodium bentonite composite waterproof pad length direction should perpendicular to bottom lying.

5. Bottom laying should be parallel lapping, considering the foundation of sinking deformation laying, can wrinkle at the bottom, appropriate relax and close to the ground tightly.

6. When laying, it can use mechanical or artificial way. Mechanical laying can take thick wall iron pipe or the iron stick to enter into roll core. One side pull open, after fixed, suspend in midair, open and flat.

7. When in construction, if sodium bentonite composite waterproof pad needs cutting, only need a knife can cut freely according to the needs.

8. When laying, strictly prohibited to put fire or cigarettes on any side of the sodium bentonite composite waterproof pad.

9. When in laying, if the sodium bentonite composite waterproof pad is broken, it should use waterproof pad that is 300 mm larger than damaged place around to cover and then fixed.

Geosynthetic clay liner rolls can be wrapped with black or white woven bags, and then on pallets or at your requirements.
