As a leading manufacturer, we produce HDPE geomembranes (0.5-3mm) for landfills, reservoirs, and canals. Factory-welded with 100% leak-proof integrity, our products meet EPA and ISO standards for environmental protection.
Installation includes: 1) Subgrade preparation includes clearing debris, compacting soil, and sand layering. 2) Unrolling the membrane while keeping it slack for thermal expansion. 3) Seam welding through double-track extrusion at 280-320°C with 1.5 to 2.5m/min speed. 4) Vacuum box tests for track seam welding. 5) Final protective cover with gravel geotextile.
