Manholes

To control and maintain pipe systems regularly, manholes are integrated in the system. The manholes are made of the same material as the pipes and are also connected to the system with similar jointing techniques. The special advantage is that a homogenous system of the same material is produced. With preference, profile types like structured and solid wall are used for the production of the manholes, as the soil can densify better at the smooth outside of the pipe and can settle without problems.
