1. Puncture resistance ≥800N (ASTM D6241).
2. Peel strength ≥100 N/5cm (EN 12317-1).
3. Withstands 30% differential settlement.
Product Introduction:
HDPE-Laminated Bentonite Blanket: A dual-layer system combining 1.5mm HDPE geomembrane with 5kg/m² sodium bentonite core, offering ≤10-¹¹ cm/s permeability. Ideal for exposed landfill caps.
Product Features:
1. Superior Crack-Bridging Capability – Our advanced composite structure features a flexible geomembrane bonded to a high-swelling bentonite core, enabling the liner to accommodate up to 10% substrate strain without compromising integrity. This makes it ideal for landfills with settling issues or earthquake-prone areas.
2. Non-Toxic & Environmentally Safe – Certified to NSF/ANSI 61 for potable water contact, our liners contain no volatile organic compounds (VOCs) or restricted substances (REACH/ROHS compliant), ensuring safe use in drinking water reservoirs and aquaculture projects.
3. Exceptional Chemical Resistance – Laboratory-tested against pH 1-13 solutions, 10% saline concentrations, and hydrocarbon mixtures (ASTM D5322), maintaining structural integrity for 30+ years in harsh industrial environments.
4. Self-Healing Properties – The activated bentonite layer demonstrates 300% faster swelling than conventional products, capable of sealing recurrent cracks up to 15mm wide through multiple wet-dry cycles.
5. High Tensile Strength – Reinforced with woven polyester scrim, achieving 45 kN/m tensile strength (ASTM D4595) to withstand heavy equipment traffic and differential settlement in mega-landfill projects.
Product Applications:
1. Achieves 10-¹² cm/s permeability when fully hydrated
2. Self-seals punctures ≤30mm diameter automatically
3. Maintains integrity through wet-dry cycles
Installation & Practices
1. Surface Preparation: Laser-grade the subgrade to ≤25mm deviation over 3m; Install 600g/m² geotextile cushion when dealing with angular aggregate (≥20mm particle size).
2. Liner Deployment: Use thermal fusion welding for HDPE components (150°C minimum seam temperature); Apply bentonite-based hydrogel at overlaps for accelerated self-sealing.
3. Anchoring & Covering: Implement 300mm deep anchor trenches with compacted backfill (95% Proctor density); For exposed applications, use UV-resistant ballast mats with ≥50% coverage.
4. Quality Control: Perform spark testing at 15kV for pinhole detection; Document all seams with GPS coordinates for lifecycle tracking.
