Natural And Non-Toxic Bentonite Geosynthetic Clay Liner For
Eco-Friendly Solutions
Product Introduction
The waterproof mechanism of sodium-bentonite waterproof blanket is
based on the high expansibility of sodium-bentonite. When sodium
bentonite particles are in contact with water, they will rapidly
absorb water and expand, filling the gap between geotextiles to
form a uniform, dense waterproof layer.
Product Properties
1. Waterproof performance: Sodium bentonite has excellent
waterproof performance and can expand in contact with water to form
a dense waterproof layer.
2. Expansibility: sodium bentonite can expand significantly when it
encounters water, adsorb more than five times its own weight of
water, and expand to more than 15-24 times the original volume.
3. Durability: As a natural inorganic material, sodium bentonite
has good durability and is not easy to aging or corrosion.
4. Environmental protection: Sodium bentonite waterproof blanket is
non-toxic and harmless, friendly to the environment.
5. Simple construction: The construction process is simple, no
special equipment is required, and the laying can be completed
quickly.
Product Application
1. Environmental protection and sanitation, domestic waste
landfill, sewage treatment site, industrial waste
2. Water conservancy, river lake reservoir dam seepage prevention,
plugging, reinforcement
3. Pond seepage prevention of garden artificial lake golf course
4. Petrochemical, mining and other fields of engineering seepage,
corrosion, leakage, reinforcement, etc.
