Composite Geomembrane The Ultimate Solution for Anti-seepage
Projects in Water Conservancy and Transportation Construction
Product Introduction
Composite geomembrane is a multi-functional impervious material
that combines the advantages of geotechnical fabric and
geomembrane. It is widely used in various fields such as water
conservancy projects, environmental protection, and transportation
construction. Here is a detailed introduction to composite
geomembranes.
Product Properties
Composite geomembranes possess a variety of excellent properties,
including good thermal resistance, cold resistance, and chemical
stability, high tensile strength, anti-aging and corrosion
resistance. They also have excellent dielectric properties,
resistance to environmental stress cracking, and increased friction
coefficients between the membrane and the base layer due to
non-woven fabric, providing good skid resistance. In addition,
composite geomembranes can withstand plant root penetration,
maintain waterproof function for a long time, and form a
high-strength waterproof layer with strong resistance to backwater
pressure. They are resistant to perforation, bursting, tearing, and
fatigue.
Product Application
Composite geomembranes are widely used in various fields due to
their excellent performance. In water conservancy projects, they
can be used for anti-seepage projects such as rivers, artificial
lakes, scenic lakes, dams, and canals. In transportation
construction, they can be used for seepage prevention and drainage
in tunnels and roads. Additionally, they are suitable for
environmental protection landfills, pollution prevention in
metallurgy and chemical industries, and construction.
To sum up, composite geomembrane is a high-performance geosynthetic
material that integrates multiple functions such as impermeability,
isolation, drainage, reinforcement, and protection. Its broad
application prospects and excellent performance make it an
indispensable part of modern engineering construction.
