[TowerTalk] ROHN SSV ERECTION QUESTIONS

[Steve Maki]

It's usually a waste of time, or worse. Weep holes plug up, the base has 
sitting water in it, the corrosion process is sped up.

*New* commercial towers almost never have grouted bases.

The only scenario where I see a benefit is if the tower base flange(s) 
are sitting so high above the foundation that the bolts need to be 
stiffened. That's a poor design or poor installation.
