Tunnel FILM construction method compatible arch section groundwater treatment material "Moyai Drain M-13PF" *NETIS registration number: CB-170004-A
The "Moyai Drain M-13PF" is a water treatment material for the arch section compatible with the tunnel FILM construction method. In the tunnel FILM method, mortar is filled into the gaps between the sprayed surface and the waterproof sheet, and the finishing is done using its adhesion. Therefore, the drainage material used for water treatment must be a product that takes the filling mortar into consideration. 【Features】 ■ The waterproof sheet is made of a special laminated sheet of polyethylene film and non-woven fabric, preventing the mortar from peeling off after installation. ■ A wide type of chemical synthetic fiber non-woven fabric, 10mm thick, is attached to both sides of the waterproof sheet, preventing mortar from flowing in from the sides of the sheet. ■ The core material M-13r has increased voids compared to previous versions, improving drainage performance and making it less likely to clog with free lime and other materials. *For more details, please refer to the catalog or feel free to contact us.
