Tunnel arch section back drainage material "Monodrain RB"
Made of polyethylene that can be easily cut with scissors! Since it is molded in one piece, it does not leak water.
"Monodrain RB" is a drainage material developed for tunnel arch sections. By integrating a rib structure to ensure water flow and an ear section for nailing, it improves both drainage functionality and workability. The lineup also includes the "RB-3050FT," which has been modified to be compatible with the smooth-back tunnel lining method (FILM). 【Features】 ■ Almost no clogging due to the adhesion of free lime ■ Easy installation with nailing ■ Measurement lines at 1-meter intervals allow for verification of usage after installation ■ Its thinness does not hinder the installation of NATM sheets *For more details, please refer to the PDF materials or feel free to contact us.
