Compound Geomenbrance Superior Geosynthetic Material For Seepage Control And Drainage
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
Product Properties
* Good anti-seepage and waterproof performance
* Good elasticity and the ability to adapt to the deformation
* Good ageing resistance, corrosion resistance ability
* Under high temperature use and long service life
Product Application
Composite geomembrane is divided into one cloth one membrane, two cloth one membrane, width 4-6m, weight 200-1500g/m2.
The product has the characteristics of high strength, good elongation, large deformation modulus, acid and alkali resistance, corrosion resistance, aging resistance, impervious performance and so on
Construction
Composite geomembrane is often used for anti-seepage treatment of dykes, drains and ditches, and anti-fouling treatment of waste yard. In addition, it is also suitable for river embankment, hydraulic tunnel, canal and Reservoir anti-seepage, metallurgical chemical anti-pollution, construction, transportation, environmental waste landfill, artificial lake and other projects
