[TowerTalk] Tower Base In Concrete

[Keith eMail]

re: tower base in concrete
In my experience you need to coat the galvanized tower with spray automotive 
type under coating, tar, or
something to protect it from the acidic concrete. I have seen several Rohn 
25 towers that rusted
off right at ground level because they weren't protected from direct 
contact. Galvanized tower and
concrete don't really play well together over the long term. I have since 
noticed that commercial grade
galvanized road culverts have a tar like coating for, I suppose, the same 
problem. Just my observation.
