I'm building a 30 X 40 shed.
Going to be using telephone poles rough cut off to 12'.
3 down each side and 3 down the middle.
Going to be using full 3x10x20 beams.6 total.
How deep should i dig hole if using quickcrete.
Also what diameter should hole be.
I've got some more questions for later.
Thanks
