Product Description
Bentonite Geosynthetic Clay Liner For High-Density And Low-Permeability Waterproofing
Sodium bentonite waterproof blanket (GCL) is a geosynthetic material which uses the high expansibility and low permeability of sodium bentonite to achieve waterproof effect.
Key Properties
- High Expansibility: Absorbs five times its own weight in water, expanding to 15-17 times original volume
- Low Permeability: Water permeability reaches 5×10⁻¹¹ m/s with strong waterproof performance
- Durability: Natural inorganic material resistant to aging and corrosion with long-term performance
- Environmental Protection: Harmless to humans and environmentally friendly material
- Easy Construction: No heating or pasting required for fast installation
Applications
- Municipal Engineering: Waterproofing for subways, tunnels, and basements
- Landfill: Waterproof layer for base treatment and capping systems
- Water Conservancy: Seepage prevention for reservoirs, dams, and rivers
- Environmental Protection: Seepage control for wastewater treatment plants and industrial waste facilities
- Garden Landscape: Anti-seepage for artificial lakes and roof gardens
Product Specifications
- Unit Weight: ≥4000g/㎡ (customization available)
- Width: 4m~6m
- Roll Length: Customizable to project requirements
