Abstract: A draining mesh module for building into a construction, such as a tunnel wall, to provide draining channels in said construction, includes at least one semi pipe of a flexible material. The draining mesh module has a longitudinal direction and a cross direction extending crosswise to the longitudinal direction. The semi pipe constitutes a part of a channel extending from one longitudinal end to an opposite longitudinal end of the draining mesh module, and that the longitudinal ends of the draining mesh module comprise attachment means for interconnecting longitudinal ends of two adjacent draining mesh modules, whereby a channel in one of those two draining mesh modules is connected to a channel in the other of those two draining mesh modules.
