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

  • vertical load test, more than 400 kN for all econorm┬«-elements
  • interconnected static checked system - from manhole bottom up to adjustable cover
