I'm building a covered deck on some weak soil (clay/sandy clay). I'm going to use 24" round footings that I was planning on reinforcing with a bunch of left over rebar. How can I effectively reinforce my footings? My though was to just cut a few lengths and tie them together using wire in an tic tac toe grid. Is there a better way to do it?
I've dug my holes 5ft deep and prep'd the ground by laying fabric in the bottom, then pouring in gravel and road crush and tamping it all down.
