- Technics: Nonwoven
Geotextile composite geomembrane is used, or other materials with the combination of the impermeable geomembrane material.
According to various engineering needs, polyester filament non-woven fabric can be used with the PE (polyethylene) composite made of impermeable membrane. Polyester filament non-composite geomembrane. Available high-strength woven geotextile, and PE impermeable membrane and polyester filament non-woven fabric (or non-woven fabric polyester staple fiber needle) composite into a high-strength composite geomembrane.
Composite geomembrane characteristics: high strength die extension of good performance variability of a large quantity of acid and alkali, anti-corrosion, bursting and tearing strength anti-aging, anti-freeze performance, when the film is not in the 70IC embrittlement. Composite Geomembrane in engineering from seepage, isolation, enhancement, anti-crack reinforcement, horizontal drainage, remediation Boiling mud, especially suitable for water
Head high, water pressure and tend to pressure the anti-seepage. Mainly used in the railway embankment seepage, reservoir dam. Landfill materials, highways and other projects carve isolation belt impervious.
