Rebar in sonotube
I'm planning on setting two 8 or 10" sonotubes approximately 12' apart, dug to 48" for Calgary frost line, plus another 6" for gravel.
I have 4 pieces of 1/2" rebar @ 48" inside two circles of 6" circumference, tie wired 12" up/down from each end, with no J or L bend on the bottom.
4 pieces of 1/2" threaded bar, not ready rod. 14" lenghts, set 12" into the concrete to hold the post holders.
Post holders are 1/4" angle, 4x6" bolted to the concrete. They will be painted with tremclad, with either an epoxy or bitumen coating at the bottom where it contacts the cement.
Gates themselves will be 3/4" angle iron frame welded 6'sq with a flat bar brace spanning 2 opposing corners of each gate.
Piers will be 6' 4x6" PT bolted into the post holders, with similar moisture barrier at the bottom asthe post holders .
Aside from it being possibly over built, is there anything I should be doing better with the rebar?
