I touched on this topic in another thread, but thought this title would get right to the point. I'd like level an existing concrete foundation which was graded rather steeply at 7 1/2'' over an 18' run. I'm looking at doing this in two locations- one under the house (carport), one on a concrete parking area. I'm thinking of cleaning the old concrete, drilling some holes in it, adding rebar to help reduce any shifting, and then call in a truck for the pour. It looks like it would be about three yards in each location. How does this manner of leveling sound? Thanks- Aaron
