Pricing depends on thickness, resin grade, surface type, and order volume. We only produce geomembranes using 100% virgin resin, and raw material prices fluctuate with the market. As reference, a 1.0 mm smooth geomembrane is typically around USD 1.2/m²- USD 1.6/m². Contact us with your project details for an exact quotation.
Prices vary by product type (geotextile, GCL, geonet, geocomposite) and technical specifications. Cost is mainly determined by raw materials, electricity consumption, and labor. We provide detailed quotations based on your requirements.
With proper installation and design, HDPE geomembranes and related geosynthetics can perform for 20–50+ years, depending on UV exposure, environmental conditions, and material selection.
Geomembranes are typically produced in 6–8 m widths with 50–150 m customizable lengths based on thickness and roll weight. Geotextiles, GCLs, and geonets are usually supplied in 4–6 m widths, with dimensions adjustable to project needs.
We use 100% virgin HDPE/LLDPE for geomembranes and premium PP/PET fibers and bentonite for other geosynthetics. All materials are sourced from reputable global suppliers and fully traceable through our digital product system.
