Strange concrete formation wall/slab joint?
Zone 6a. My post war home is in a neighborhood (unbeknownst to me at the time) notorious for for foundation issues. And I found I’m in the same boat. The foundation repair man did his walk through and pointed at my slab/wall joint, he said it was an oddity with the extra protrubance of cement. (This exists the full run of the walls) he said he was not sure but it could mean I dont have footings, that I might have a slab below grade? (All new to me and my googling hasn’t helped find similar photos or anything) Take a look, what’s your opinion? What does that mean for me? Any websites or references for reading would be welcome. I think my slab is 5 and a half feet below grade, additional 2 foot above dirt before framing takes over.
