HDPE Impermeable Geomembrane
Description
Technical Parameters
In the field of environmental protection engineering, anti-seepage is the bottom line. Once leakage occurs, repair costs exceed the initial investment by more than 10 times. Our HDPE impermeable geomembrane is manufactured using 100% brand-new high-density polyethylene resin as raw material, blended with 2-3% carbon black, antioxidants and UV absorbers, and produced via extrusion blow molding or calendering processes. This HDPE impermeable geomembrane features a permeability coefficient as low as 1×10⁻¹³ cm/s, several orders of magnitude superior to traditional anti-seepage materials, making it the preferred material for high-risk anti-seepage projects such as landfills, sewage treatment tanks and tailings ponds. Multiple landfill projects we have serviced have recorded zero leakage after over 10 years of operation-this is the power of superior quality.

Chemical park sewage tanks and mine tailings ponds operate under far harsher environments than ordinary engineering sites. Our HDPE impermeable geomembrane delivers outstanding chemical stability, resisting strong acids, strong alkalis and various organic solvents, with an applicable pH range of 2 to 14. Meanwhile, the molecular structure of high-density polyethylene endows it with excellent puncture resistance; textured variants further enhance the friction coefficient of slope surfaces to prevent landslides. Our product line includes smooth and textured types, covering thicknesses from 0.5mm to 3.0mm with a maximum width of 8 meters, drastically reducing on-site welding joints and lowering leakage risks. For agents serving environmental protection projects, our HDPE impermeable geomembrane delivers unbeatable technical parameters for bidding purposes.

Factory Strength
As a professional manufacturer with 12 years of deep engagement in waterproof and anti-seepage materials, our HDPE geomembrane production lines are imported from Germany and adopt advanced extrusion blow molding processes for stable product quality and superior performance. The monthly output reaches 800,000 ㎡, capable of meeting bulk supply demands for large-scale engineering projects. The factory is equipped with a full set of physical performance testing equipment, with complete data records traceable from raw materials to finished goods. Our products have been exported to over 30 countries and regions including Southeast Asia, the Middle East and Africa, earning an excellent reputation in overseas markets. By partnering with us as a supplier, you gain access to premium products and a partner familiar with international markets who can support your project bidding efforts.
Customization Capacity
We fully recognize that different projects impose vastly different requirements on geomembranes, so we offer comprehensive customization services. Thickness ranging from 0.2mm to 3.0mm can be produced, with a maximum width of 8 meters; roll lengths are customized to minimize on-site splicing. Surface types include smooth, single-textured and double-textured options to meet varying slope friction coefficient requirements. Black is the standard color, with other colors available upon special request. If you have specific technical indicator requirements such as higher tensile strength or superior environmental stress crack resistance, our R&D team can adjust the formula accordingly. Flexible MOQ supports small trial orders to lower market development risks for you.
After-Sales Service
Construction quality directly impacts the anti-seepage effect of geomembrane projects, so we attach exceptional importance to construction technical support. Our technical team can provide remote welding guidance to help your construction crews quickly master the double-track hot melt welding process. For complex projects, on-site construction guidance and quality inspection by technical personnel can be arranged (fees apply separately). All delivered products come with complete quality guarantee certificates and testing reports, covered by a 1-year warranty. If material quality issues arise during construction, we will immediately send replacement materials to avoid project delays. Upon project completion, we can assist you in compiling as-built documents to smooth acceptance procedures.
