What are the differences during installation of plastic manholes compared to manholes of other materials?

Plastic manholes can be installed much easier due to their light weight, needing a smaller trench and providing huge flexibility of connections.


  • The installation of plastic manholes is more cost saving because of the light weight and easy handling.
  • The outside dimensions of a plastic manhole are smaller. 
  • The width in the trench beside the plastic manhole can therefore be smaller even allowing for sufficient space (150 mm) around the manhole to allow compaction equipment to compact the pipe zone with backfill material in the trench. 
  • A large choice of prefabricated parts and connections diameters / angels gives full flexibility ensuring a fast installation.
