Double-Membrane Single-Fabric Composite Geomembrane For Environmental Protection
Product Introduction
Double-membrane Single-fabric Composite Geomembrane is a common geotechnical material made by compounding two layers of geomembranes with a layer of geotechnical fabric in between. This structural design not only takes advantage of the excellent impermeability of the geomembranes but also enhances the tensile strength and extensibility of the geotechnical fabric, making the overall material more adaptable and durable.
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.
