Composite Geomembrane For Impermeability And Reinforcement In Environmental Protection
Product Introduction
Geosynthetic membranes are impermeable materials made by combining plastic films as the base material for impermeability with non-woven fabrics. Their 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. Due to its excellent properties, composite geosynthetic membranes are widely used in various water conservancy projects for impermeability, such as river channel seepage control projects, river management projects, artificial lake seepage control projects, landscape lake seepage control projects, dam seepage control projects, canal seepage control projects, etc.
Product Properties
Composite geomembranes are flexible and, in addition to the
isolation, drainage, reinforcement, and protection functions of
geotechnical fabrics, they also have a sealing (waterproofing)
function. Their applications are extremely diverse, including water
conservancy dams, transportation tunnels, road construction,
airports, drainage, buildings, environmental protection, and many
other fields. In engineering projects, they mainly serve as
waterproofing, protection, and reinforcement.
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
