Product Description
Natural and non-toxic bentonite geosynthetic clay liner engineered for eco-friendly waterproofing solutions across multiple industrial applications.
Waterproof Mechanism
The waterproof mechanism utilizes sodium-bentonite's high expansibility. When sodium bentonite particles contact water, they rapidly absorb moisture and expand, filling gaps between geotextiles to form a uniform, dense waterproof barrier.
Key Properties
- Superior Waterproof Performance: Forms a dense, impermeable layer upon water contact
- High Expansibility: Absorbs over 5 times its weight in water and expands 15-24 times original volume
- Exceptional Durability: Natural inorganic material resistant to aging and corrosion
- Environmentally Friendly: Non-toxic and harmless composition
- Easy Installation: Simple construction process requiring no special equipment
Applications
- Environmental Protection: Landfill sites, sewage treatment facilities, industrial waste containment
- Water Conservancy: River, lake, and reservoir dam seepage prevention and reinforcement
- Landscaping: Pond and artificial lake seepage prevention for golf courses and gardens
- Industrial: Petrochemical and mining engineering for seepage, corrosion, and leakage control
