Product Description
Sodium bentonite geosynthetic clay liner (GCL) represents an advanced geosynthetic material engineered for superior seepage prevention across diverse construction applications. This innovative product integrates graded natural sodium bentonite particles with specialized admixtures, securely fixed between geotextile and plastic woven cloth through precision needling technology.
Key Performance Characteristics
  • High Expansion Capability: Sodium bentonite exhibits exceptional expansibility, forming a dense impermeable diaphragm under water pressure with outstanding self-water retention properties. Upon water contact, bentonite undergoes significant expansion to create a gel-like barrier, substantially enhancing anti-seepage effectiveness.
  • Streamlined Installation: The waterproof blanket features simplified construction procedures with reduced installation timelines, making it suitable for waterproofing projects across varied environmental conditions including landfills, artificial lakes, underground garages, and rooftop gardens.
  • Long-Term Durability: Composed of natural inorganic materials, the liner maintains structural integrity over extended periods and environmental changes, eliminating concerns about aging or corrosion while ensuring persistent waterproof performance.
Application Scope
This geosynthetic clay liner finds extensive application in water conservancy, environmental protection, transportation infrastructure, railway construction, civil aviation projects, and various civil engineering disciplines. It serves critical functions in foundation treatment and sealing systems for landfills, artificial lakes, reservoirs, channels, rivers, basements, subway tunnels, underground passages, and diverse subterranean structures requiring reliable seepage prevention.
