Product Description
Versatile Bentonite Geosynthetic Clay Liner for Various Waterproof Applications
A high-performance geosynthetic material engineered for superior waterproofing and environmental protection in demanding industrial applications.
Product Overview
Bentonite waterproof blanket is an innovative geosynthetic material manufactured using high-expansibility sodium bentonite fixed between two layers of geotextile or woven cloth through specialized needling processes. This advanced construction delivers exceptional waterproof performance across diverse engineering applications.
Key Performance Features
- Excellent waterproof performance: Sodium bentonite provides high self-water retention and rapidly expands to form dense, impermeable diaphragms upon water contact
- Superior durability: Natural inorganic bentonite composition ensures resistance to aging and corrosion for long-lasting waterproof performance
- Environmental safety: Natural bentonite material is non-toxic and environmentally friendly, certified as green construction material
- Simplified installation: Streamlined construction process adapts efficiently to complex terrain and environmental conditions
Industrial Applications
- Artificial lakes and water features: Prevents water leakage and maintains water quality integrity
- Landfill containment: Effectively prevents leachate leakage to protect surrounding environments
- Underground structures and green roofs: Provides reliable rainwater infiltration protection for building structures
- Industrial storage facilities: Prevents chemical leaks and environmental contamination at oil depots and chemical dumps
