I have a steel square pole that is 11 feet height, 11cm depth and 11 wide.
The post is for a wooden heavy gate which is 4 foot high and a bird house at 7 foot high from the ground.
If I float the 11 foot steel pole in the concrete at 3 foot with bolts coming out of the steel pole at the bottom, would that work ? or would I need to put in steel bars in the ground with the concrete ?
Also will be putting back top soil and there is lot of big rocks under the ground where I am digging the hole (there is an old building foundations in the ground where the hole will be.
