Bob, I may be missing the point here. But if you are doing a pole mount, the concrete is primarily providing ballast (to counteract the uplift forces of wind). The sideways forces are counteracted by the diameter and depth of the hole in the ground (the physical dimensions if you wish) and the compaction value of the soil; not the weight of the material that fills the hole. I know I am using layman's terms but I think that the jist of what I am saying is true. So you don't need rebar to provide weight to counteract uplift forces, but rebar may be need to keep the concrete mass in one piece. I would be surprised if Array Technologies didn't have structural engineering reports specifying concrete and rebar needed for their pole mounts (are you using their product?). Most AsHJ will defer to a stamped engineering report from the manufacturer as to how to install their product. - Peter

This will have to be a tall pole mount and I just wanted to pick the collective experience of the group. Any ideas as to how to go at this? Thanks, Bob
