I am having a monolithic slab poured (25' x 30') with 16" (w) x
18" (d) footings. 18" is below the frost line in my area. This slab will also have a 6" (h) x 4 1/2" (w) curb along the outside edge. I am a little concerned about the quality of the work by the contractor. My questions: Should the curb have re-bar? If so, what size? There will be anchor bolts (j bolts) 4' o.c. along the curb. How should the re-bar (#4 (1/2')) be set in the footings? By that I mean how far below the surface should the top re-bar be? There are 4 lines of rebar in the footing, two near the bottom and two near the top. In my layman opinion, the top set is too close to the surface. Also, the re-bar is tied to a vertical length of rebar driven into the ground. Is this acceptable? Any comment will be appreciated.- posted
