Description:
Textured HDPE geomembrane has excellent temperature adaptability, weldability, weatherability and good aging resistance, chemical corrosion resistance, environmental stress cracking resistance and puncture resistance. Therefore, it is especially suitable for underground projects, mining projects, landfills, sewage or waste residue treatment sites as leakproof materials.
Textured HDPE geomembrane is a new type of anti-seepage material. Textured HDPE geomembrane with single and double textured surface can increase friction coefficient and anti-skid function. It is more suitable for steep slope and vertical anti-seepage and improve engineering stability.
There are two different type of textured HDPE, normal textured and pointed textured.
Product Features:
1.Long life, anti-aging, roof material can be more than 30 years, underground can be more than 50 years.
2.Good tensile strength, high elongation.
3.Good high/low temperature flexibility
4.Easy to construct, no pollution.
5.Good anti-corrosive ability, can be used in special area
6.Various colors are available
7.Skidproof
