Compound Geomembrane The Optimal Solution For And Durable
Anti-Seepage
Product Introduction
Geosynthetic Membrane is a type of geotechnical impervious material
made by combining plastic film as the impervious base material 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.
Using geosynthetic membranes can improve efficiency and save
engineering time.
Product Properties
1. High puncture resistance and large coefficient of friction
2. Excellent resistance to aging, wide range of ambient temperature
adaptability
3 Excellent drainage resistance
Product Application
♦ Municipal construction: includes impervious lining for subways,
basements and tunnels.
♦ Environmental Protection: anti-seepage treatment of landfill.
♦ Agricultural Water Conservancy: anti-seepage pavement of
irrigation system.
♦ Traffic facilities: highway, railway subgrade anti-seepage
treatment.
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
