Product Description
Bentonite Waterproof Blanket for Seepage Prevention
Sodium bentonite waterproof blanket is an advanced geosynthetic material engineered for superior seepage prevention in various construction and environmental applications. This innovative product combines graded natural sodium bentonite particles with specialized admixtures, securely fixed between geotextile and plastic woven cloth using advanced acupuncture manufacturing processes.
Key Product Properties
- Excellent Impermeability: Sodium bentonite expands significantly upon water contact, creating an effective waterproof barrier
- Environmental Durability: Natural inorganic composition ensures long-term performance without aging or corrosion
- Simple Construction: Easy installation with short construction periods, adapts to foundation settlement and self-heals cracks
Primary Applications
- Landfill Engineering: Base treatment and capping material for waste containment systems
- Water Conservancy Projects: Anti-seepage treatment for reservoirs, channels, and river systems
- Municipal Construction: Waterproofing for underground garages, roof gardens, artificial lakes, and pools
- Transportation Infrastructure: Waterproof protection for underground structures in rail transit projects
