Wide Wall Manhole Chamber

Tongue and groove precast wide wall concrete manhole chamber.

A 130 mm thick wide wall chamber, in combination with the Easi-Base unit, provides a sealed watertight manhole system. This robust design means that the requirement for a concrete surround is eliminated.

FP McCann’s precast concrete wide wall manholes have been designed with a tongue and groove dimension to accommodate the use of bituminous sealant.

Included in object:

- DN1500 Wide wall manhole chamber
- DN1800 Wide wall manhole chamber
