HDPE anti-skid point geomembrane also named as column point geomembrane. Point evenly distributed with increased friction force, and the appearance is very beautiful, The two sides of geomembrane can be hot melted together by different color and materials. We can set right side or reverse side of products according to geological conditions and project requirements. The product is produced by processing of hot-welt, extension in reasonable controlling, which increase products' tensile strength, puncture strength, abrasion resistance. It retains superior mechanical property and excellent elongation and stable chemical property of raw materials. And through adding functional agents in fixed proportion, which improved product's functions of anti-acid & alkali and anti-corrosion. It's tensile strength 3 times higher than normal I textured geomembrane.
ASTM HDPE column point geomembrane is a common geosythetic product widely used in human-made project as a waterproof material.Geomembranes are made from relatively thin continuous polymeric sheets, but they can also be made from the combination of geotextiles with asphalt, elastomer or polymer sprays, or as multilayered bitumen geocomposites. Continuous polymer sheet geomembranes are, by far, the most common form.
Textured surface is specially designed to increase the sureface friction force so as to improve the stability of the building materials over it.
