Versatile Compound Geomembrane for Various Construction Projects
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
* 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
* Earth-rock dams, rockfill dams, laying bricks dams, roller
compacted concrete dams.
* Channels, liquid storage pool (pits, mines)
* To be the waterproof layer of expansive soil and collapsible
loess.
* Cofferdam construction.
* Lining seepage control of subways, basements, and tunnels.
* Saline control of roadbeds and other foundations.
* Tailings dams, water reservoirs, the reservoir areas, and the
waste plants.
* Moistureproof seepage control of roofings, basemens.
* To be horizontal impervious blanket for dikes,dams, vertical
seepage layer for foundations.
Construction
* For laying geomembrane, edge welding bead lap width 80mm-100mm,
juncture place cannot have dirt, moisture, dust, etc
* Adjust two sides of geomembrane before welding seams ,keep a
certain wedling width, and smooth without creasing.
* More details refer geomembrane construction scheme
