Single-Textured HDPE Geomembrane
- Aquaprufe
AG-TGI Single-Textured HDPE Geomembrane is made with virgin PE resins, together with carbon black and other additives. One surface is smooth and the other is textured, irregularly concave and convex. The product meets the GRI-GM13 standard.
It is produced by the advanced technique of 4-layer extrusion and film blowing, which ensures even thickness. And the asperity is flocculent PE sprayed by nitrogen, enabling it to maintain a better tear resistance performance. The texture provides great friction force to prevent sliding, while the smooth side has high tensile strength and elongation.
Uses
AG-TGI Single-Textured HDPE Geomembrane is suitable for anti-seepage and erosion control projects with certain anti-sliding requirements.
Typical applications would be municipal environmental protection, water conservancy, seepage proofing works of projects including aquaculture, waste disposal, landfill, metallurgy, petrochemical, mining, transport, landscaping, etc.
Advantages
Anti-aging & anti-UV
Resistant to oxidation, chemicals and bio-enzyme degradation
High tensile strength & extensibility
High friction force & anti-sliding on the textured side
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 0.75mm to 3.00mm in thickness, and up to 8m in width for each roll.
Storage
AG-TGI Single-Textured HDPE Geomembrane 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.
