Composite Geomembrane

Two-Way HDPE Composite Geomembrane | ASTM D4886 & GB/T 17643 Standard Anti-seepage Material

HDPE Composite Geomembrane for Aquaculture

Product Overview

Dezhou Shengyuan New Materials Technology Co., Ltd. is a professional manufacturer of high-quality composite geomembrane, which is produced by advanced hot compound process, perfectly combining non-woven geotextile and high-density HDPE geomembrane into an integrated anti-seepage material. This product integrates the excellent filtration, drainage, protection and reinforcement functions of geotextile with the super anti-seepage, isolation and corrosion resistance properties of geomembrane, forming a high-performance composite geotechnical material.

Our composite geomembrane fully complies with ASTM D4886 (American Standard) and GB/T 17643 (National Standard), with stable performance and reliable quality. It is widely used in various global anti-seepage projects, including solid waste landfills, aquaculture ponds, water conservancy dams, highway tunnels, sewage treatment plants, mining projects and environmental protection engineering, solving the anti-seepage problems of various complex engineering environments efficiently and durably.
