EVA waterproof membrane is made from a special formula of native resin with a certain proportion of EVA
added. It is produced through the compression and flattening extrusion process. During the production pro
cess, hanging straps can be added as fixation, and can be suspended for auxiliary construction to achieve
nail free laying, improve laying quality and efficiency, and significantly reduce the overall cost of the project.
The product thickness is generally designed as 1.5mm, 2.0mm, 2.5mm, 3.0mm, with a width of mostly 3 m
eters. The length is generally determined according to engineering design requirements.
Features:
EVA waterproof membrane has good flexibility, flexibility, and excellent low-temperature bending resistanc
e. It has excellent anti-seepage and high barrier properties, acid and alkali resistance, and chemical
corrosion resistance.
Scope of Application:
Mainly used for railway tunnels, highway tunnels, subways, and various municipal underground anti-see page projects. Currently, the standards for
EVA waterproof film implementation include highway tunnels GB/T 18173.1-2012 and railway tunnel standards TB/T3360.1-2014.
