Product Description
Product Overview
Sodium bentonite geosynthetic clay liner (GCL) is an advanced composite material engineered for superior waterproofing and impermeability in civil engineering applications. This innovative solution combines graded natural sodium bentonite particles with geotextile layers through specialized manufacturing processes.
Key Performance Features
- Exceptional Waterproof Performance: Sodium bentonite absorbs water equivalent to several times its own weight, expanding to form an impermeable gel barrier
- Ultra-Low Permeability: Permeability coefficient typically below 1×10⁻⁹ cm/s for long-term reliable waterproof protection
- Multi-functional Application: Provides waterproofing, reinforcement, isolation, and filtration capabilities in geoengineering projects
- Cost-Effective Solution: Superior performance-to-cost ratio compared to alternative waterproof materials
Applications
This geosynthetic clay liner is extensively used in landfill foundation treatment and capping, artificial lakes, reservoirs, channels, rivers, roof gardens, and underground structures including basements, subways, tunnels, and underground passages. Additional applications include municipal engineering, building foundations, waste management facilities, industrial containment, and environmental protection projects.
