This joint is right in front of the house and has become uneven due to settling in the clay soil we now live in. The slab is 12' x 12' reinforced concrete with a #4 rebar in a perimeter beam and wire mesh. I've been wondering how to correct it for some time now. This morning I had an idea to saw a control joint at a diagonal across the slab from one corner to the other allowing the slab to settle back into place. Might work? Nothing to lose at this point I guess. Expert at work!!!! Ha. See the results later.
