Composite Geomembrane High Tensile and Puncture Resistance for Engineering Applications
Product Introduction
Geomembrane is a type of impervious material made by combining plastic film as the base material for impermeability with non-woven fabric. Its impermeability mainly depends on the impermeability of the plastic film. Polyethylene (PE) is a high molecular weight chemical flexible material with low density, strong extensibility, high adaptability to deformation, corrosion resistance, low temperature resistance, and good frost resistance.
Product Properties
Composite geomembranes have high physical and mechanical properties, including tensile resistance, tear resistance, puncture resistance, etc. These indicators ensure that they can withstand external loads and are not easily damaged in engineering applications. For example, composite geomembranes have high tensile, tear, and puncture resistance, indicating that they have good strength and durability.
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
