Product Description
Waterproof Bentonite Geosynthetic Clay Liner
Sodium bentonite waterproof blanket (GCL) is an advanced geosynthetic material engineered for superior seepage prevention in various civil engineering applications. This innovative product combines graded natural sodium bentonite particles with specialized admixtures, securely fixed between geotextile layers using advanced manufacturing processes.
Key Performance Advantages
- Exceptional Waterproof Performance: Sodium bentonite expands significantly upon hydration, forming a dense gel-like impermeable barrier with excellent self-water retention capabilities
- Long-Term Durability: Natural inorganic bentonite composition ensures resistance to aging and corrosion, providing permanent waterproof protection
- Simplified Installation: Easy construction process with minimal equipment requirements, suitable for complex environmental conditions
- Environmental Safety: Non-toxic, environmentally friendly material containing no harmful substances
- Superior Deformation Resistance: Maintains structural integrity and stability under varying geological conditions and ground movements
Application Areas
- Water Resources & Environmental Engineering: Landfill liners, artificial lakes, reservoirs, channels, and riverbank protection
- Transportation Infrastructure: Subway tunnels, underground passages, basements, and rooftop gardens
- Municipal Construction: Sponge city development, ecological restoration of rivers and lakes
- Industrial Facilities: Chemical storage areas, oil depots, and other leakage prevention applications
