Seepage-proofing; roadbed and other foundation salt marsh prevention and cure function, isolation product use, basements and tunnels: Geotechnical dam, mine), foundation vertical impervious barrier; waste storage, tunnel impermeable lining; road, rockfill dam, railway roadbed; subway, sewage reservoir dam body and reservoir area, stone masonry dam and pressing concrete dam, highway; expansive soil and waterproof layer of collapsible loess; construction cofferdam; dyke, reservoir tank (pit; channels; roof leakage-proofing, horizontal impervious blanket in front of dam; tailings dam
Mainly include polyvinyl chloride (PVC) and polyethylene (PE), corrosion-resistant, EVA (ethylene & # 47 geomembrane taking plastic film as anti-seepage base material, good extensibility. Currently, they are a kind of polymer chemistry flexible material, the material used for seepage-proofing at home and abroad is plastic film, high?adaptability?to the?deformation; vinyl acetate copolymer), smaller proportion, and design use ECB (ethylene vinyl acetate modified bitumen blend geomembrane) in tunnel application, low temperature resistance, good anti-frost?property. , geotechnique impermeable material combined with non-woven fabric. Its anti-seepage property mainly depends on the anti-seepage property of plastic film.
