HDPE Compound Geomembrane 0.2~3mm For Cofferdam Construction

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


Product Application

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.
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
