Corrosion-Resistant Impervious Geotextiles for Long Service Life
Product Introduction
Impervious geotextileis a kind of geotextile which is composed of plastic film as anti-seepage base material and non-woven fabric. Its anti-seepage performance mainly depends on the plastic film's anti-seepage performance. The main plastic film used for anti-seepage at home and abroad are polyvinyl chloride (PVC) and polyethylene (PE) , which are polymer chemistry flexible materials with small specific gravity, strong extensibility, high adaptability to deformation, corrosion resistance and low temperature resistance, good Frost resistance. The main mechanism is that the leakage passage of the earth dam is separated by the impermeability of the plastic film, which can bear water pressure and adapt to the deformation of the dam body with its high tensile strength and elongation
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
