900g Composite Geomembrane High-Performance Material for Anti-Seepage in Civil Engineering
Product Introduction
Composite geomembrane is an impermeable material composed of geotextile and geomembrane, which is mainly used for anti-seepage. It has high tensile, tear resistance, blasting and other physical and mechanical properties, to meet the Water Conservancy, construction, transportation, Subway, tunnel and other civil engineering needs. Due to the selection of polymer materials and the addition of anti-aging agents in the production process, it can be used in unconventional temperature environment
Product Properties
The composite geomembrane has a certain amount of deformation, and the stress transfer and dispersion speed of the concave and convex defects of the base cushion are fast, and the strain capacity is strong. The pore pressure and buoyancy on the interface between composite geomembrane and soil are easy to dissipate. It has a certain heat preservation effect, increased the soil frost heave on the destruction of geomembrane and HDPE geomembrane, thus increasing the soil deformation. In addition, the composite geomembrane has excellent anti-aging function and engineering maintenance and other advantages
Product Application
Composite geomembrane is widely used in canal anti-seepage engineering. It has been widely used in anti-seepage works of irrigation canal. Composite geomembrane is widely used in many fields such as hydraulic engineering, construction and transportation because of its excellent impermeability and wide applicability
