Product Introduction

Bentonite geosynthetic clay layer

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.

Features

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

Application:

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.
