    Frequently Asked Questions

    What is the difference between one-cloth-one-membrane and two-cloth-one-membrane composite geomembrane?
    One-cloth-one-membrane consists of a single geotextile layer bonded to a single geomembrane layer, making it economical and suitable for general anti-seepage applications. Two-cloth-one-membrane sandwiches a geomembrane between two geotextile layers, providing bidirectional protection, higher tensile strength and superior puncture resistance — making it the mainstream choice for most engineering projects.
    What is the permeability coefficient of your composite geomembrane?
    Our composite geomembrane achieves a permeability coefficient of ≤1×10⁻¹¹ cm/s, which meets the highest standards for water-tight barrier applications in reservoirs, landfills, sewage treatment plants and other critical anti-seepage projects.
    What temperature range can your composite geomembrane withstand?
    Our composite geomembrane is designed to perform reliably across a wide temperature range of -60℃ to +80℃. It is anti-UV and anti-aging, with a design service life of 50 to 100 years under normal installation and operating conditions.
    Can specifications such as width, thickness and weight be customized?
    Yes. We support full customization of width (standard range 2m–7m), film thickness (0.2–1.5mm), base cloth weight (80–1000 g/m²) and roll length to match your specific project requirements. Custom specifications help reduce seam overlap, minimize leakage risk and lower overall construction costs.
    Which industries and applications are composite geomembranes suitable for?
    Composite geomembranes are widely used across water conservancy (dams, reservoirs, canals), environmental protection (landfills, sewage treatment), municipal infrastructure (tunnels, underground pipe galleries), transportation (highway subgrade, tunnel waterproofing), agriculture and aquaculture (fish ponds, irrigation canals), and mining and chemical industries (tailings ponds, chemical pools).
    Do you provide technical support and after-sales service?
    Absolutely. We offer comprehensive support including professional technical guidance, construction scheme recommendations, on-site welding training and full after-sales assistance. Our team provides one-stop solutions covering product selection, procurement and installation to ensure your project is completed successfully.
