High density Polyethylene (HDPE) Plastic Benched Manholes  are prefabricated to clients specific requirement, fully extrusion welded and tested, simple connection via mechanical or electro-fusion jointing onto pipe lines will give a completely sealed and integrated system.

Insitu Concrete benched manholes typically involve staged construction, requiring specific equipment and various trade skills. In addition works have to be sequentially programmed over a number of days and invariably involve complex and unnecessary H&S and confined space issues.
