[TowerTalk] Ufer ground using copper wire

[David Gilbert]

I assume you mean the top end of the copper clad steel ground rod 
shouldn't be embedded in the concrete, and that is true.  But if he 
buries the Cadweld joint (wire to ground rod) in the dirt below the 
bottom of the hole, with only the copper wire entering the concrete, I 
can't see where there would be an issue (discounting the urban legends 
about exploding concrete, of course).  Ufer grounds for house 
foundations have the copper wire exit the concrete below grade all of 
the time without worry about corrosion.
