Smooth Finish HDPE Geomembrane
- Aquaprufe
AG-SG Smooth Finish HDPE Geomembrane is made with virgin PE resins, together with carbon black and other additives. It is produced by the advanced technique of 4-layer extrusion and film blowing, which ensures even thickness and stable mechanical properties compared to calendaring.
It is used for anti-seepage purposes in a wide range of civil engineering projects. AG-SG accords with the GRI-GM13 standard. It has excellent impermeability, strength performance and durability. Color customization is available.
Uses
AG-SG has a low friction rate due to its smooth finish, and it is usually used for flat areas or projects with low friction rate requirements, no soil coverage and high anti-seepage standard.
Typical applications would be municipal environmental protection, water conservancy, seepage proofing works of projects including aquaculture, waste disposal, metallurgy, petrochemical, mining, transport, landscaping, etc.
Advantages
Anti-aging & anti-UV
Resistant to oxidation, chemicals and bio-enzyme degradation
High yield strength & extensibility
Strong tear & puncture resistance
Great Low-temperature flexibility, no brittle failure even under -70°C
Great impermeability, with permeability coefficient of <10-13g·cm/ (cm2·s·Pa)
Customized color available for each layer

Application Procedures
Substrate cleaning - Geomembrane positioning - Welding - Engineering inspection
Packaging
Available from 0.25mm to 3.00mm in thickness, and up to 8m in width for each roll.
Storage
AG-SG is designed to last 70 years under natural conditions and the service life remains the same if it is not stored or used in harsh environments. The optimal storage environment would be shady, dry and at room temperature.
