LLDPE Geomembrane

Selection depends on the contained medium, subgrade, water head, exposure, slope geometry and project standard. Send the drawings and service conditions; we will recommend the material grade and thickness for engineering approval rather than using one thickness for every project.

HDPE and LLDPE seams are normally made by dual-track hot-wedge welding; extrusion welding is used for details and repairs. Trial seams, air-channel tests, vacuum-box tests and destructive seam samples should follow the approved installation quality plan. We can provide welding parameters and remote or agreed on-site guidance.

Polyethylene geomembranes resist many aqueous chemicals, but compatibility depends on concentration, temperature, exposure time and stress. Provide the chemical list and operating range before ordering. For critical containment, compatibility testing or confirmation by the project engineer is recommended.

Quotation is based on resin type, thickness, surface, roll width and length, quantity, test standard, packaging, Incoterm and destination port. Wide-roll and folded-roll options can reduce field seams and improve container utilization. Send the required area and roll plan for a comparable factory quotation.

Depending on the product and contract, we can provide factory batch test reports, roll identification, raw-material and production records, packing and loading photos, certificates of origin and available third-party reports. Required standards and inspection points must be confirmed in the purchase order.
