I'm not a concrete guy, but I figure 27 cubic feet of concrete per yard.
A 3x3x4 hole is 36 cubic feet.
6 holes = 216 cubic feet or 8 yards of concrete.
How do you get by with a 1/2 yard of concrete per hole?
This has been of great interest to me as I'm ready to pour 1 3x3x4 hole for
some Rohn 25. I have a hand mixer lined up, but after reading these posts I
believe I'll forget it and get a concrete truck and a load of dirt to fix the
I figured the hole + 4 inches above the ground = 39 cubic feet or about 1.5
yards of concrete. This still leaves the guy points which I was going to do
with the hand mixer, but now I'm not sure about that either.
Have I figured this wrong?
