3. Resists microbial degradation.
Product Introduction:
Haoyang Environmental's engineered composite liner combines a 1.5mm high-density polyethylene (HDPE) geomembrane with a 5.0kg/m² needle-punched bentonite core, creating an unparalleled barrier solution for critical containment applications. The system delivers industry-leading ≤10⁻¹² cm/s hydraulic conductivity (ASTM D5887) while maintaining 800N puncture resistance (ASTM D6241), achieved through our proprietary fusion bonding process that ensures 95% bentonite retention under 50kPa hydraulic pressure. Third-party testing confirms the composite withstands 15% strain without compromising impermeability, making it ideal for differential settlement areas in landfill bases.
Our certified containment solution features NSF-approved sodium bentonite with consistent 24mL/2g swell index (ASTM D5890), encapsulated between reinforced polypropylene geotextiles for superior tensile strength (≥25kN/m, ISO 10319). The pre-hydrated edge seals activate within 4 hours of installation, creating continuous barriers that exceed EPA Subtitle D requirements. Available in 5.8m wide rolls with factory-applied seam indicators, the system reduces installation time by 40% compared to conventional clay liners while providing equivalent performance at 1/10th the thickness.
Product Applications:
1. Landfill Liners - High-density polyethylene geomembranes prevent leachate contamination in waste disposal sites, meeting strict environmental regulations.
2. Mining Leach Pads - Chemical-resistant liners safely contain acidic solutions in metal extraction processes while allowing controlled drainage.
3. Water Canal Linings - UV-stabilized geomembranes reduce water loss in irrigation systems by up to 95% compared to traditional methods.
