Wide Wall Chambers
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.
