Manhole

Standard manholes are equipped with a one-piece PU channel element with integrated manhole connections from DN 150 to DN 400 in the smooth pipe cylinder, as well as internal integrated buoyancy protection.

Manholes are delivered as standard without steps on request, various kinds of steps can be installed: standard rungs, step irons and stainless steel steps. We particularly recommend the use of ladder systems made of aluminum or stainless steel – these are normally attached to stainless steel bolts set into the inner wall. Other variants are available on request.

The manhole base unit DN 600 to DN 1000 are basically equipped with a one-piece PU bottom element that allows connections from nominal size DN 150 upwards. Extension sections are fitted with proven joint systems in accordance with EN 295 and permanent pressure transfer.

Cover slabs come as standard with a corrosion-resistant PU lining from nominal size DN 800 upwards.
