[TowerTalk] Tower base/Ufer ground

[Mike Reublin NF4L]

Thanks Dave. It's a crank-up and has a rebar cage that the tower bolts to.

If the ground water level is that high, though, I'd probably worry about the culvert eventually rusting out.  Rebar is cheap enough in comparison to the cost of that much concrete that I think I'd drop a few 10' long sticks into the pour for a Ufer anyway.  Just connect them to the tower legs as if the culvert wasn't there.  Cheap insurance, in my opinion.
