Product Description
Sodium Bentonite Geosynthetic Clay Liner
Natural sodium bentonite waterproof blanket with superior impermeability and environmental protection properties for various engineering applications.
Product Overview
Sodium bentonite waterproof blanket is manufactured using natural sodium bentonite particles mixed with specialized admixtures, uniformly distributed and securely fixed between two layers of geotextile through advanced production technology. This composite material combines the essential characteristics of geosynthetics—including separation, reinforcement, protection, and filtration—with exceptional waterproofing capabilities.
Key Features & Benefits
  • High Expansibility: Sodium bentonite expands at least 24 times when hydrated, forming a uniform colloidal system with high viscosity and minimal filtration loss
  • Superior Waterproof Performance: Withstands hydrostatic pressure up to 0.6MPa for one hour without leakage, achieving permeability coefficient as low as 5×10⁻¹¹ cm/s
  • Exceptional Durability: Natural inorganic composition ensures no aging reaction occurs, providing long-term performance stability
  • Environmental Safety: Non-toxic and environmentally friendly material, harmless to humans and ecosystems
  • Easy Installation: Can be installed in temperatures below 0°C, requiring only placement, fixing, and overlapping procedures
  • Simple Repair: Damaged sections can be easily restored with straightforward repair methods
  • Cost-Effective Solution: Wide range of applications with compatibility to international geotextile specifications, enhancing construction efficiency
Applications
  • Garden Landscape: Water feature projects including artificial lakes and roof gardens for water retention and quality maintenance
  • Transportation Engineering: Roadbed reinforcement and waterproofing for roads and railways to improve load-bearing capacity and stability
  • Construction Sector: Underground structures, roof reservoirs, and other building components for leakage prevention
  • Mining Industry: Tailings pond seepage prevention to contain metal ions and prevent environmental contamination
