[TowerTalk] Gravel under forms

[Chris Hoelzle]

Hello - I am putting up two towers. A 55g and a 45g. I have built my cages,
and soon, I will dig my holes for the cages and cement.

My questions are:
Do you use gravel in the bottom of the holes?
What size gravel
Does it need to be tamped down
How do you support the anchor rod while the cement is setting up
Do you use a Vibrator to get the cement to release the air
and finally
Do you use 4000psi cement?

Thanks for your advice
