econorm plus® – Manhole system with future

The quality standard for the future

PRINZING has developed the manhole further. Based on the PRINZING patented econorm® gasket – an integrated gasket with load compensation attributes – PRINZING built a manhole system which is also accepted as an European PAS-Standard.

A system with future
At the installation the manhole sinks safely by its own weight in the smooth and stable, not resilient filling of the gasket.
