Customizable Compound Geomembrane For Various Terrains And Applications
Product Introduction
Compound geomembrane is a compounded geosynthetic material compositing of two or more materials of geotextiles (or fiber), polymer materials (such as PE film, EVA, etc.). It is formed via the calender, hot melt coating,which geotextiles being guide water and polymer materials as the impervious layer. Having special seepage control, protection and reinforcement, drainage, isolation, and other functions, its high toughness and excellent chemical attack resistance, anti-aging performance are greater than the simple geotextile or simple gemomembrane. Aslo it is convenient to construction for wider applicastions range.
Product Properties
1. Impervious Performance: The geomembrane in the middle ensures good impervious performance, preventing water seepage.
2. Robust Structure: The two layers of geotechnical fabric on the top and bottom enhance the overall tensile strength and stability, capable of withstanding external loads.
3. Adaptability: The material has excellent flexibility to accommodate various terrains and changes in the foundation surface.
4. Durable: The selected high molecular materials and added anti-aging agents ensure its long-term use in various environments.
Product Application
1. Water Conservancy Projects: Such as reservoirs, artificial lakes, and seepage control in river channels.
2. Municipal Engineering: Used for impervious construction of landfills and wastewater treatment plants.
3. Traffic Construction: Reinforcement of road and railway subgrades and drainage.
4. Environmental Protection: Remediation of polluted soil and covering of solid waste.
