Existing pipe below new slab on grade
Existing pipe below new slab on grade
(OP)
Situation: Exist 8" water main, not in use anymore, invert level 5' below top of new proposed 5" SOG. The contractor is wondering if he can fill the pipe with concrete, cap it each end and leave it in place.
Personally I think at the given depth it should be OK. Concrete in the pipe will shrink a little but due to the depth of the pipe, any pressure from the slab can bridge around the pipe.
