Slab not square – where to compensate?
I building my own two-car garage, but had a contractor pour the slab. I ended up with the wrong contractor, but luckily it’s not a horror story, just a cautionary tale.
Anyway, the slab is out of square – it’s 20’x20′, and the diagonals differ by 4-1/4″.
Should I ignore this and just make sure each wall is square and plumb? Or are there adjustments I should make as I erect the walls to keep them square to each other?
