Rehabilitation of Sewer Manholes

For the rehabilitation of sewer manholes, we prefer the use of fibreglass pots, which are fitted into the unsuitable or leaking shafts. The lower part of the manhole, i.e. berms and channels, is newly made of plastic concrete. The rehabilitated manhole is then fitted with non-corrosive step irons. The rehabilitation of manholes using fibreglass pots is used primarily in case of high ground water level or whenever a perfectly watertight sewer system is required.
