HDPE Geomembrane Specifications

1. High-quality raw materials
HDPE geomembranes consists of 97.5% high-density polyethylene and about 2.5% carbon
black, anti-aging agent, antioxidant and UV absorber and other auxiliary materials to ensure
superior product performance.

2. Excellent performance
HDPE geomembrane has strong anti-seepage and isolation capabilities and is suitable for a
variety of environments.

3. Advanced technology
HDPE geomembrane adopts the leading four-layer co-extrusion process to ensure product
quality and stability.

4. Enhanced friction and interfacial adhesion
Compared to the smooth, HDPE geomembrane textured feature an additional sandblasted
surface layer, significantly improving slope stability and ground slip resistance. Dual-textured
geomembrane can also be engineered to address more complex qeotechnical challenges.
