High Weld Seam HDPE Geomembrane ≥15MPa ASTM D6392 Hot Wedge Welding for Large Landfill Reservoir Liner Installation

High Seam Strength HDPE Geomembrane - ≥15MPa Weld Integrity

Designed for reliable large-area installation, this HDPE geomembrane delivers seam strength ≥15MPa per ASTM D6392 through hot wedge fusion welding. The consistent resin quality and optimized melt flow index ensure uniform, leak-proof welds across the entire project area, minimizing the risk of seam failure.

Welding Performance

• Seam shear strength: ≥15MPa (ASTM D6392)
• Seam peel strength: ≥100N/25mm (ASTM D6392)
• Double-track weld capability for air pressure testing
• Compatible with all major hot wedge welders (Leister, Demtech)
• Melt flow index optimized for consistent welding

Project Applications

Large-scale landfill liner installation, reservoir bottom and side lining, mining heap leach pad construction, wastewater lagoon lining projects, and any application requiring extensive field welding with quality assurance.
