Interior Footing Embedment
Interior Footing Embedment
(OP)
Hello,
I have a question regarding minimum embedment for interior footings. Per IBC 1809.4 it states you need minimum 12" undisturbed for all footings. In the field it seems as though there are frequent cases where interior pad footings bear directly on the soil with minimal embedment. Anyone know a code reference for interior footings either strip or pad footings for residential applications? I have been unable to find anything with regards to this, so I am guessing it is min 12" per 1809.4? Thanks for any input.

12" would be absolute minimum. I would not ever allow 6" thickness in any residential ftg, 12" is minimum for pad ftgs, and 8" is min for wall ftgs.
Here in Phoenix, despite no frost, it is actually 18" minimum embedment req'd

I meant 8" thick wall ftg with 4" ext grade cover, but here in PHX we need that wall ftg to be embedded at least 18" BELOW top of ext grade.

Or 18" here in PHX.
