High-Performance HDPE Smooth Geomembrane For Long-Lasting Waterproofing Solutions
Product Introduction
Smooth surface geomembrane is a kind of waterproof barrier material with high polymer as the basic raw material, mainly high density polyethylene (HDPE) geomembrane.
Product Properties
The smooth geomembrane has excellent environmental stress cracking resistance and chemical corrosion resistance, wide temperature range and long service life.
Product Application
It is widely used in the fields of landfill, tailings storage, channel seepage prevention, dam seepage prevention and subway engineering.
