“Hao” Product — Specialized Geosynthetic Membrane For Extremely Cold Regions

Special geosynthetic membrane for extreme cold regions

Pain points of conventional geosynthetic membrane applications

Low-temperature brittleness problem

Ordinary geomembranes tend to become brittle and crack below -20°C, leading to the failure of anti-seepage. Freeze-thaw cycles cause material aging, shortening the service life by more than 30%.

Poor environmental adaptability

The drastic temperature difference (-70°C to 20°C) causes the material to contract/expand and deform, resulting in poor structural stability. The permafrost layer is highly active, and traditional geomembranes are prone to being punctured or torn.

                                                    Characteristics of geomembranes specifically designed for extremely cold regions

                                           Anti-seepage engineering for high-altitude or regions with extreme temperature variations

01

Extremely long crack resistance life

700h+ NCTL (ASTM D5397 test), the crack propagation resistance is increased by 80%, and the risk of brittle fracture caused by stress concentration in traditional HDPE films is avoided.

02

Full environmental adaptability

It combines UV resistance, acid and alkali resistance, and freeze-thaw resistance. It remains flexible under extreme temperature differences (-30℃ to 40℃), and its service life is extended to over 50 years.

03

Low-temperature flexibility

The highly flexible HDPE geomembrane remains elastic at -30℃, avoiding the cracks caused by the embrittlement of traditional HDPE geomembrane at low temperatures.

04

Weather resistance

It enhances the resistance to ultraviolet rays and aging, and is suitable for anti-seepage projects in areas with extreme cold or significant temperature differences.
