Premium Bentonite Geosynthetic Clay Liner (GCL) – 2024’s Top Choice for Eco-Friendly Sealing

High-Performance Bentonite Core
Engineered with ultra-absorbent sodium bentonite clay, offering unmatched hydraulic conductivity (<1×10⁻⁹ cm/s) for superior fluid barrier protection. Self-sealing properties activate upon hydration.
Reinforced Geotextile Layers
Dual-layer nonwoven/polypropylene fabric encasement enhances puncture resistance (up to 1,500 N) while maintaining flexibility for uneven surfaces. Needle-punched fibers prevent bentonite migration.
Versatile Industrial Applications
Ideal for landfill caps, pond liners, tunnel waterproofing, and secondary containment. NSF-certified for potable water projects. Withstands extreme temperatures (-40°F to 150°F).
Easy Installation & Cost Efficiency
Pre-hydrated rolls (3.3ft x 82ft) enable rapid deployment—40% faster than traditional compacted clay. Lightweight design cuts transport/logistics costs by 60%.
Sustainable & ASTM-Compliant
Zero VOC emissions. Meets ASTM D5887/D6768 standards. Recyclable polypropylene components reduce environmental impact vs. PVC alternatives.
Global Wholesale Advantage
Factory-direct pricing for bulk orders (MOQ: 10 rolls). Custom-cut widths available. Ships worldwide in 7 days with moisture-proof packaging.
