"Hao" Product - Geomembranes Designed for Extremely Cold Regions

Pain Points in Conventional Geomembranes

1.Low-Temperature Brittleness

Ordinary geomembranes tend to become brittle and crack below -20°C, resulting in waterproofing failure. Freeze-thaw cycles cause material aging, shortening service life by over 30%.

2.Poor Environmental Adaptability

Severe temperature swings (-70°C to 20°C) cause material contraction/expansion deformation, resulting in poor structural stability. Frequent permafrost activity makes traditional geomembranes susceptible to puncture or tearing.

Features of Geomembranes Designed for Extremely Cold Regions

Anti-Seepage Projects in Extremely Cold or Extremely Temperature-Varied Regions

01Extremely Long Crack Life

700h+ NCTL (ASTM D5397 test), increasing crack propagation resistance by 80%, eliminating the risk of brittle fracture caused by stress concentration associated with traditional HDPE membranes. 

02. All-Environmental Adaptability

This product offers triple-effect protection against UV rays, acid and alkali, and freeze/thaw. It maintains flexibility even in extreme temperature fluctuations (-30°C to 40°C), extending its service life to over 50 years.

03. Low-Temperature Flexibility

This highly flexible HDPE geomembrane maintains its elasticity even at -30°C, eliminating the cracking associated with traditional HDPE geomembranes due to low-temperature embrittlement.

04. Weather Resistance

This product offers enhanced UV and aging resistance, making it suitable for anti-seepage projects in cold and extreme temperature regions.
