China HDPE Smooth Surface Geomembrane is made by heat-bonding nonwoven or woven geotextile to HDPE geomembrane by calendaring processing technology. BPM composite vides the advantages of both geomembrane and geotextile, which is made of specially formulated HDPE resin combined with specified quantity carbon black, anti-aging agent and UV resistance components. The geotextile layer increases essential tensile strength and the geomembranes provides exnt impermeable, leak and moisture proof. Compared with traditional concrete, aslt and compacted clay, China HDPE Smooth Surface Geomembrane has proven to be far more cost effective, environmentally safe, exnt durable, chemically resistant, fast deployment and easy transportation. Composite mainly used in water dams, artificial lakes, airports, construction, environmental protection, water containment and other projects.
