Here's what I did. I found a local company that would supply, cut and bend
the rebar per the cage design specs. They had the professional machinery to do
this properly and accurately. That's the hard part. Took it all home in my
pickup truck and put it together on-site using conventional rebar wires ties.
I did order several pieces of small diameter rebar and tied them on as
diagonals on each side to provide rigidity and have the cage hold it's shape.
Had the backhoe guy lower it into the hole after excavation, laying it so that
each vertical rebar was on thick concrete pavers to keep the rebar from
touching dirt (a bad thing which will cause the rebar to rust, expand and
fracture the concrete). Also want at least 3.5 inches between the cage and the
dirt sidewalls for the same reason.
Good luck with your project.
