I had this slab poured for my garage 2 summers ago. So two winters of exposure, and it’s spalled this badly already. The apron is fine. A little slab I poured 10 years ago right next to it is fine. What might have caused this? Freeze thaw obviously, but why here and not the apron or the other slab?
Upstate New York, bad winters of course, but still, this just seems faulty.
