Flexible rainwater and drainage pipes for directing rainwater away from the walls and the vicinity of the foundations. Meltex’s flexible rainwater and drainage pipes have a strong SN8 ring stiffness class but are still flexible due to their manufacturing material. With flexible pipes, it is easy to go around building corners, terraces, and bay windows without separate corner connection pieces. Connecting discharge pipes from roof drains to the main line is also effortless. Flexible pipes are also easy to transport: a coil fits even in a trailer, and a few flexible pipe sections can be coiled into the trunk of a car.
