Product Description
Sodium Bentonite Geosynthetic Clay Liner is an advanced waterproofing solution composed of sodium bentonite particles sandwiched between geotextile layers. This environmentally friendly geomaterial offers exceptional hydraulic performance with fluid loss ≤18 mL and permeability as low as 5×10⁻¹¹ m/s.
Key Product Properties
- High Expansibility: Rapidly expands upon water contact to form an impermeable gel barrier
- Low Permeability: Achieves hydraulic conductivity of 5×10⁻¹¹ m/s for superior waterproofing
- Exceptional Durability: Natural inorganic composition provides excellent aging and chemical corrosion resistance
- Environmental Safety: Non-toxic, harmless, and environmentally friendly with natural degradation properties
- Easy Installation: Simple transport and construction without requiring specialized equipment
Primary Applications
Ideal for landfill liners, pond and reservoir sealing, tunnel waterproofing, foundation barriers, and environmental containment projects requiring reliable hydraulic protection.
Standard Specifications
- Unit Weight: ≥4000 g/m² (custom options available)
- Width: 4-6 meters
- Roll Length: Customizable to project requirements
- Fluid Loss: ≤18 mL
