Product Description

Introduction

Composite geomembrane is a geosynthetic material made from materials such as high-density polyethylene (HDPE) or polypropylene (PP). Its main uses are as follows:

Waterproof function: Composite geomembrane has excellent waterproof performance and can be used to prevent water infiltration and leakage. It is suitable for water conservancy and environmental engineering such as embankments, reservoirs, sewage treatment tanks, water tanks, tunnels, etc.

Anti corrosion function: Composite geomembrane has excellent chemical corrosion resistance and can be used to prevent soil, water or chemical substances from corroding structures. It is suitable for mining, chemical plants, landfill sites and other engineering projects.

Isolation function: Composite geomembrane can effectively isolate different soil layers or materials, prevent their mutual infiltration or mixing, and is suitable for civil engineering projects such as highways, railways, airports, and docks.

Reinforcement function: Composite geomembrane can resist tensile and tearing forces, and is used to reinforce soil, prevent slope landslides, soil erosion, etc. It is suitable for land improvement, river management and other engineering projects.

Conservation function: Composite geomembrane can be used as part of soil and water conservation measures to protect soil moisture and reduce soil erosion. It is suitable for projects such as farmland and vegetation restoration.

Working Drawing

In addition to the above functions, composite geomembranes can also be used in fields such as land protection, coastal engineering, and landscaping. It not only has high strength and durability, but also provides reliable engineering and environmental protection effects, making it one of the important materials commonly used in civil engineering.
