Business consultingDetailed introduction
HDPE rough surface high density polyethylene geomembrane has excellent temperature adaptability, weldability, weather resistance and good aging resistance, chemical corrosion resistance, environmental stress cracking resistance and puncture resistance. Therefore, it is especially suitable for underground engineering, mining engineering, landfill, sewage or waste residue treatment field as anti leakage material.
HDPE smooth surface (rough surface) high density polyethylene geomembrane is a new type of impermeable material. HDPE geomembrane such as single rough surface and double rough surface increases friction coefficient and anti-skid function, which is more suitable for steep slope and vertical seepage control and improves engineering stability. Product series: single rough surface, double rough surface, column point non-slip, foot clamp solid.
