Have you talked w/ any concrete places to see about just pouring a new floor over this one? ANY wood on concrete needs a capillary break, so I'd be leery of your plan w/out addressing that.
Ayuh,.... How thick are ya talkin' to get to 3 yards,..??I just checked the grade to confirm my numbers and I was a bit off. The dimensions of the area to be regraded are 18'x14' with a grade of 7 1/2'' over the 18' run. By my calculations, (and they could be wrong):wink:, that's about 3 yards of concrete.
Ayuh,.... Where ya feather the new concrete to 0", there'll always be an eroding edge, due to the thinnest of the concrete....That's 7 1/2'' at it's deepest to 0'' at the other end where it will meet level concrete. I've never done this before, did I do it incorrectly?
