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

FP McCann’s approved sealant should be used at all times. The sealant requirements for wide wall manholes is 12mm x 120mm x 6m. When placing the sealing strip into position during installation, the ends of the strips must be overlapped by a minimum of 30mm and cut at an angle of 60°. The cut ends must then be pressed together. Full installation guidelines can be provided upon request or found in the downloads section to the left.

DN1200, DN1500 and DN1800 Wide Wall Manhole Chambers

A 130mm 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.

Advantages of Wide Wall Manhole Chambers:

  • Quick and easy installation
  • Watertight structure
  • Safe anchor lifting system (spherical head lifting system)
  • Greater cost savings associated with using precast concrete over a traditional system
  • No concrete backfill required, in accordance with ‘Sewers for Adoption’ 7th edition
  • More environmentally friendly than a traditional system, almost 40% less carbon emitted during the concrete casting process
  • Significant reduction in health and safety risks associated with using precast concrete

Please note: Wide Wall Manhole Chambers are manufactured with 3 x 45mm diameter lifting points to facilitate the safe anchor lifting system (spherical head lifting system).
