I have an issue with soil erosion below the front corner of my garage floor which has caused a crack to form and a piece of the slab (~4sq.ft) to sink. This in turn is affecting the portion of the outside wall which is supported by the area to sink/lean.
The garage was built by previous owners and is a simple concrete-block wall with a brick veneer on the outside. The part of the front wall that is currently sitting on the cracked piece is only about 3' but I imagine it's likely that the void underneath is larger.
I'm currently reading up on concrete jacking, but am worried about the additional load of the wall on the slab. I know that it's typically recommended to wait 24h before driving on a jacked slab, so would the concrete jacking process have enough pressure to fix my situation?
If there's another approach that I might be missing, I'm also open to suggestions.
