HDPE geomembranes are widely used in impermeable lining projects such as landfills, artificial lakes, and water conveyance channels. However, when actual on-site installation begins, many issues arise not from the welding technique itself, but from inadequate preliminary preparation—such as failing to inspect materials, level the subgrade, test equipment, or check weather conditions—leading to repetitive, corrective work. Clarifying all necessary details before installation is far more efficient than having to redo the work later.
When the HDPE geomembrane arrives on site, do not rush to unload it. Verify the roll markings, specifications, thickness, width, and batch numbers against the design documents and the delivery manifest. Conduct a visual inspection to check for surface damage, holes, significant scratches, or adhering debris, as well as any deformation of the roll core. Safely store documentation such as factory test reports and certificates of conformity, as these will be required for subsequent acceptance inspections and supervisory reviews.
