Versatile Compound Geomembrane The Optimal Construction Solution
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
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
