This system worked well for us as the #5 rebar was really stiff. We tried to bend it to make the curve, but it kinked and didn't curve. We overlapped as much as 36 inches in some places, but the requirement for this rebar is 2 foot 6 inches. We used the 2 foot stakes to place the tension on the rebar like weaving a basket. In and out, every other one. The chairs are not very supportive, but they hold the rebar the required 3 inches off the bottom of the ground. The final rebar will be placed today (Jan 4th) and we'll move the airform to the center of the pad. Checking the measurements of the stemwall to the airform is critical, we want to be exact. Then we'll place the vertical rebar in the stemwall (4 inches x 7 inches) for pouring.
