High-Strength Sodium Bentonite GCL – Eco-Friendly Geosynthetic Clay Liner with 4-6m Width for Anti-Seepage Applications

Eco-friendly anti-seepage blanket engineered for environmental protection applications.

Sodium Bentonite Geosynthetic Clay Liner (GCL) is a high-performance geosynthetic material manufactured by fixing graded sodium bentonite particles between geotextiles and woven fabrics using advanced needle punching technology.

This eco-friendly waterproof membrane combines the superior properties of geosynthetic materials with exceptional waterproof and anti-seepage performance. The sodium bentonite core exhibits strong water swelling capacity, forming a dense, impermeable barrier upon hydration that effectively blocks water penetration and ensures project safety.

• Compact volume with excellent flexibility and sealing performance
• High shear strength and adaptability to uneven settlement
• Lightweight design for easy transportation and installation
• Compatible with various complex terrain conditions
• Forms dense, stable waterproof layer with long-term anti-seepage effectiveness
• Superior to traditional compacted clay liners in performance and installation efficiency

Primarily used in environmental engineering projects requiring sealing, isolation, and anti-seepage solutions:

• Landfills and waste containment facilities
• Tailings dams and hazardous waste storage yards
• Artificial lakes and landscape water systems
• Underground infrastructure construction

Provides excellent anti-seepage performance and strong damage resistance, effectively preventing leakage of harmful substances and protecting ecological environments.

Three-layer composite structure:

• Top Layer: Geotextile
• Middle Layer: Sodium bentonite core
• Bottom Layer: Woven fabric

This engineered structure ensures product stability and optimal waterproof performance. The needle punching process securely fixes bentonite particles, eliminating leakage risks during application.
