Tongue and groove precast concrete, 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.
