Flexible Anti-Seepage Sodium Bentonite GCL with 4-6m Width and ≥24ml/2g Swelling Index for Complex Terrain

Flexible anti-seepage solution designed for complex terrain applications.

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 two fabric layers, creating a blanket-like waterproof membrane with exceptional flexibility for complex terrain applications.

Widely used in environmental protection and civil engineering projects including:

• Landfills and tailings dams
• Hazardous waste storage yards
• Artificial lakes and landscape water systems
• Underground garages and basements
• Various underground infrastructure anti-seepage projects

Three-layer composition ensures optimal performance:

• Top Layer: Geotextile (protective function)
• Middle Layer: High-quality sodium bentonite (core anti-seepage layer)
• Bottom Layer: Woven fabric (enhances tensile strength)

All layers are securely bonded through needle punching technology, ensuring integrated product performance.
