Running a FW line under a foundation

Running a FW line under a foundation

Running a FW line under a foundation

(OP)
Due to the congestion of existing and proposed utilities a 12" FW line must be routed under the foundation of a proposed single story building.

Does anyone have experience with this. Wondering if a trench with slurry backfill below the foundation is choice. Would CI piping be the only option?

RE: Running a FW line under a foundation

The preferred pipe material is ductile iron since it is stronger than ductile iron.

Any pipe that pass under a footing or through a foundation wall shall be provided with a relieving arch; or there shall be built into the masonry wall a pipe sleeve two pipe sizes greater than the pipe passing through.

The pipe should be installed in the customary manor, there is no need for pipe slurry. Underground (ductile iron) piping is generally installed with flexible joints.

You should make sure that the piping is encased in poly to prevent corrosion.

CLSM may be used as structural fill or backfill in place of compacted soil. The flowable characteristics of CLSM allow it to be readily be placed into a trench and into tight or restricted access areas where placing and compacting fill is difficult. CLSM is used as bedding material for pipe because the mixture easily fills voids beneath the pipe and provides uniform support.

Appreciate the feedback. DIPRA, how cool is that.
