Product Description
High-Performance Sodium Bentonite Geosynthetic Clay Liner
Premium impermeable barrier with exceptional waterproof properties and environmental durability for demanding civil engineering applications.
Product Overview
Sodium bentonite waterproof blanket is manufactured using sodium bentonite as the primary raw material through needling, needling coating, or adhesive processing methods. When exposed to water, sodium bentonite expands more than 24 times its original volume, forming a uniform colloidal system characterized by high viscosity and low filtration.
Key Properties
- Excellent waterproof and impermeable characteristics
- Inorganic material composition prevents aging reactions
- Superior durability and environmental compatibility
- High viscosity colloidal formation upon hydration
Applications
Sodium bentonite waterproof blanket is extensively utilized in:
- Municipal engineering and subway construction
- Building underground engineering and roof reservoir seepage prevention
- Domestic waste landfill sites and sewage treatment facilities
- Seepage prevention and reinforcement for dams, rivers, lakes, and reservoirs
Standard Specifications
- Unit Weight: ≥4000g/㎡ (customization available)
- Width: 4m~6m
- Roll Length: Customizable according to project requirements
