footing missing under an existing foundation
footing missing under an existing foundation
(OP)
I have a 4" slab on grade foundation. 8" cinderblocks, filled, 24" below greade, 36" above grade. Eventhough my blueprints state that there should be an *" x 20" footing under my cinderblocks I was unhappy to find no footing what-so-ever. My foundation has not sunken or anything like that and I am not sure if I like the idea of underpinning. Are you allowed to escavate and just poor a footing under the cindeblocks in a similar style as underpinning?

In your case, you have to take steps to NOT undermine your block wall.

I know this sounds like heresy but, there many soils/loading conditions for which the footing is only required as a leveling pad to place the superstructure on. This may be one of those cases.
