Geomembrane plastic film used as seepage-proof base material and combined with woven cloth geotechnique seepage-proofing material new material geomembrane anti-seepage property mainly depends on plastic film anti-seepage property at present at home and abroad seepage-proof application plastic film mainly include polyvinyl chloride (PVC) and polyethylene (PE), EVA (ethylene / vinyl acetate copolymer), tunnel practical design using ECB (blending geomembrane of ethylene-acetic acid-ethylene modified asphalt) a kind of high polymer chemistry flexible material, with small proportion, strong extensibility, high?adaptability?to the?deformation, corrosion resistance, low temperature resistance and good anti-frost property.
