Do NOT use cinder blocks or red brick to support iron for the pour
Use concrete material, block pieces, curb stop etc. The purpose
is to keep moisture away from the iron. Cinder and red brick pass the
moisture through.
At least that's what we were told in the before time when I worked
as an iron worker.
I have an HD-90, it's a tough tower. The base got away from me
and we used 22 yds of concrete. It ain't going nowhere.
