Product Description
Customized Bentonite Geosynthetic Clay Liner
High-performance waterproof and impermeable material utilizing natural sodium bentonite swelling properties for effective seepage control in reservoirs, dams, and environmental engineering applications.
Key Product Properties
- High Expansibility: Sodium bentonite expands significantly when exposed to water, forming a gel-like waterproof layer
- Low Permeability: Excellent water resistance with very low permeability characteristics
- Durability: Natural inorganic material with superior aging resistance and chemical corrosion resistance
- Environmental Safety: Made from natural bentonite, non-toxic and environmentally friendly
- Easy Installation: Simple construction process requiring no special equipment
Applications
- Landfill Engineering: Base treatment and capping to prevent pollutant infiltration
- Water Conservancy Projects: Waterproof layers for reservoirs, dams, rivers, and canals
- Underground Construction: Waterproofing for subways, tunnels, and underground structures
- Building Applications: Leak prevention for basements and moisture retention in roof gardens
- Landscape Engineering: Seepage control for artificial lakes and waterscape projects
Standard Specifications
- Unit Weight: ≥4000g/㎡ (customization available)
- Width: 4m to 6m
- Roll Length: Custom specifications available
