EVA waterproof board
Negotiable /Case
Min.Order:1 Case
Waterproof material especially used in tunnel
Hanging waterproof board is a type of new waterproof material used in tunnel only developed by our company which can no nail holes, one-off hang in construction and simplity the difficulty of traditional materials in tunnel construction,improve the quality and efficiency of laying, short the construction time, greatly reduce cost of project and have good advantages of market competition.
Peoducts
Separated waterproof board: one layer of geotextile and one layer of geomembrane with strips
Compound waterproof board:whole composite of geotextile with tape and geomembrane, point and strip composite,there is welding line at the edge and the strips in geotextile will be laid as a whole at site one time.

EVA point waterproof board especially used in tunnel
Besides anti-seepage function in engineering construction it also have anti-skidding function between second lining in the laying of tunnel construction.Roughness of point geomembrane uniformly distributed which can insert the concrete layer,Compared with traditional EVA waterproof board.It has increased friction coefficient, and its fixed effect is well.Since the convex support of point, there is a space between the interface of waterproof board and concrete. So it is easy to drainage, It also have high effciency and multi-function, It is the best special materials in tunel project for anti-seepage and drainage,
Tunel waterproof &drainage project,landfill project.
