New Brunswick, Canada | Surprisingly even old coils of barbed wire can be used as ring style reinforcement, almost anything steel will work to some degree if you can keep it off the bottom. We used welded wire mesh in our shop to tie the heat tubing to, it was laid over top of a 4 x 4 ft x 1/2" rebar grid on chairs just to make it easier to hold the mesh up. Many of the folks that work concrete in the residential side of things have no respect for the steel placement and you have to watch them like a hawk.
Will hog panels work? Sure, figure out the cross section of the steel in them, figure out how far apart the control joints are gonna be and decide a maximum acceptable crack size so you can figure out how much overlap you need to get the right square inches of steel in the cross section. If you have a big slab it needs lots more steel that you would think. Careful about using the largest acceptable crack size too, as it gets wider the cracks can displace and give rough floors. | |

Concrete question: use old hog panels as reinforcement?
