Wide Wall Manhole Chamber Dimensions

 

FP McCann wide wall manholes have been designed with a tongue and groove dimension to accomodate the use of bituminous sealant.  An FP McCann approved sealant should be used at all times.  The sealant requirement for wide wall manholes is 12mm x 120mm x 6mm.  When placing 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 degrees.  The cut ends must then be pressed together.
