Welcome to econorm®
The manhole system with safety and responsibility. The success of econorm- showed: Hardly a substitute is roughly coming nearer to the requirements of the econorm-. You recognize the original every time on:
- the undivided integrated gasket with cast-in load compensation
- not resilient load compensation around
- clear access 610 mm
- vertical load test, more than 400 kN for all econorm®-elements
- interconnected static checked system - from manhole bottom up to adjustable cover
