Standard round manholes

In addition to its range of IDEAL inspection pits for connection to pipe diameters less than DN700 mm, De Bonte Group produces a range of round inspection pits for connection to concrete pipes from DN700 mm. We have standard pits up to diameter 2.000 mm.

All pits are approved and have CE-marking. To make your project complete we also offer, for all larger diameters and dimensions of pits, custom constructions.

• Cast in smooth, dimensionally stable self-compacting concrete
• Fitted with built-in flow profile, available with slopes
• Larger diameter concrete pipes are connected using slip connectors
• These pits have an improved flow profile, which prevents silting and dirt deposition from wastewater
• The inspection pits are constructed using matching shaft elements and cover plates
