hdpe geomembrane liner for waterproofing 

1. HDPE waterproofing geomembrane for tunnel    
1) Thickness : 0.15mm - 4.0mm .
2) Width : Within 8 m (1m-8m) .
3) Length : 50m-100m/roll (as request) .
4) Material : HDPE,( LDPE, LLDPE, PVC, EVA ).
5) Color : Black , white , red , blue , or as request .
6) Optional surface : Textued(one or two side) or smooth surface .
7) The second big pond liner manufacturer/factory in China for many years .

hdpe geomembrane liner for waterproofing  is based on the material of plastic film, relative to the HDPE geomembrane has better applied and suppleness, is to update the generation of soil seepage control material. LDPE geomembrane and geotextile glue them into a soil anti-seepage material it has corrosion resistance, good low temperature resistance, light quality, laceration resistant ability and other characteristics; The characteristics of its low cost, high quality and low price is not matched by other same category geotechnical seepage control material.

Technical Parameters (ASTM)

hdpe geomembrane liner for waterproofing 

Features: 1) Can bear chemical erosion.

2) A wider using temperature range and a longer using life. Application: It can be widely used in areas of garbage burying, waste disposal, tail minerals storage and underground construction projects. Technical craft: The HDPE geo-membrane is produced by a method of three layer co-extrusion model. The raw material is processed at 200 by fusing and coextrusion, whose basic properties are kept during the producing process.
