Composite Geomembrane The Versatile Solution for Anti-Seepage and Anti-Leakage in Artificial Lakes and Fish Ponds
Product Introduction
Composite geomembrane is a kind of geosynthetic material that integrates multiple functions. It combines the advantages of geotechnical fabric and geomembrane, and is widely used in various fields such as water conservancy projects and environmental protection projects. Here is a detailed introduction to composite geomembranes.
Product Properties
Impervious Performance: The impervious performance of composite geomembranes mainly depends on the high molecular weight impervious materials they contain, such as polyethylene (PE) and high-density polyethylene (HDPE). These materials have excellent water pressure resistance and corrosion resistance, maintaining stable impermeability in various environments.
Mechanical Properties: The composite geomembrane has high tensile strength and tear resistance, capable of withstanding significant mechanical stress, making it suitable for engineering projects requiring high strength.
Durability: Due to the use of high molecular materials, composite geomembranes have excellent anti-aging properties and a long service life. For example, when laid by burial, their lifespan can reach 50-70 years.
Easy Construction: The width of the composite geomembrane can reach six meters, reducing the number of seams and thus lowering the project cost and construction time. Additionally, it does not require additional adhesives, making construction more convenient.
Product Application
The application scope of composite geomembranes is very extensive, mainly including the following aspects:
Hydraulic Engineering: Used for anti-seepage projects of rivers, reservoirs, dams, etc., effectively preventing water seepage and protecting water resources.
Environmental Engineering: In environmental facilities such as landfills and wastewater treatment plants, composite geomembranes are used for impermeability to prevent leakage of pollutants and protect the environment.
Traffic Engineering: In the construction of transportation infrastructure such as highways, railways, and tunnels, composite geomembranes are used for road reinforcement, drainage, and seepage prevention.
Civil Engineering: Composite geomembranes also find extensive applications in building construction, such as foundation seepage control and roof waterproofing.
