In Pit Fusion

When the host pipe is too deep for above ground fusion, joining of the starting stock is done in the pit at the elevation of the host pipe. Fusion can be done over a variety of lengths. Factors determining the length of starting stock are weight, sub-surface configuration, or maximum size of pit allowed. Trench boxes may be needed as shoring to allow safe access into the pit. General guidelines suggest shoring for pits deeper than 4'-6".

Starting Stock LengthsPit Length*Pit Width*

Fusion - 20'25'4'
Fusion - 30'35'4'
Fusion - 40'45'4'
