Sodium Bentonite Geosynthetic Clay Liner is an eco-friendly geosynthetic waterproof material composed of graded sodium bentonite particles, geotextiles, and woven fabrics. Through advanced needle punching technology, bentonite particles are uniformly fixed between fabric layers, creating a blanket-like waterproof membrane with exceptional flexibility for complex terrain applications.
Key Performance Advantages
Compact volume and lightweight design for easy transportation and installation
Superior flexibility that adapts to uneven settlement and foundation movement
Excellent sealing performance forming dense waterproof layers upon hydration
High shear strength ensuring project stability and durability
Streamlined construction process improving efficiency and reducing costs
Application Areas
Widely used in environmental protection and civil engineering projects including landfills, tailings dams, hazardous waste storage yards, artificial lakes, landscape water systems, underground garages, basements, and various underground infrastructure anti-seepage applications. Effectively blocks water and harmful substances to protect ecological environments and ensure project safety.
Multi-Layer Structural Design
Top Layer: Protective geotextile Middle Layer: High-quality sodium bentonite (core anti-seepage layer) Bottom Layer: Woven fabric (enhances tensile strength) All three layers are securely bonded through needle punching technology, ensuring optimal product performance.
