I have a sloped concrete drive that enters into the garage/shop. I got the house and it's been abandoned for a long time but I am having a few issues. I went to put anchor bolts in and it's not lining up level and if I do get it level, the garage is on the edge (actually hanging over the concrete). See that gap. It's shifting more and more away from the garage I'm wondering.... Should I remove that sloped concrete and use new concrete with small rebar squares or what. I'm a noob at all levels on construction but dont have cash to pay people. Thanks in advance.
