Premium Bentonite Geosynthetic Clay Liner (GCL) – Superior Leak Protection & Environmental Safety

High-Performance Waterproof Barrier
Made with premium sodium bentonite clay sandwiched between durable geotextiles, ensuring exceptional hydraulic conductivity and self-sealing properties for long-term leak prevention.
Engineered for Extreme Conditions
Reinforced needle-punched nonwoven fabric enhances tensile strength, resisting punctures and soil pressure, ideal for high-stress landfill, basement, and pond applications.
Eco-Friendly & Low Maintenance
Natural bentonite clay expands upon contact with water, forming an impermeable gel layer without harmful chemicals—perfect for sustainable construction and environmental projects.
Versatile Industrial & Civil Use
Widely applied in landfills, tunnels, reservoirs, and underground structures for reliable containment, erosion control, and waterproofing.
Cost-Efficient Bulk Solution
Pre-assembled rolls enable fast installation, reducing labor costs and project timelines compared to traditional compacted clay liners.
Global Wholesale Advantage
Direct factory pricing ensures unbeatable value for large-scale procurement, backed by rigorous quality compliance (ASTM, GRI-GCL standards).
Trusted by Professionals
Preferred by engineers and contractors for its consistent thickness (5.8-7.2 mm), uniform bentonite distribution, and UV-resistant outer layers for exposed applications.
