> Have the same tower, I am wondering about the benefit of grouting,
especially after taking down a TMM433 that had a lot of rust underneath
the base plate as a result of the grouting. My inspection of street
light standards has been inconclusive 50/50 grout/no grout. Same with
cell towers with nuts under the base plates, mostly no grout.
> Besides UST recommending it, why is it an advantage?
You use non-shrink grout and it's supposed to become part of the
weight bearing base.
If you flood the base with grout, it should keep out any water - well,
most of the water anyway.
And the LXC Prime Directive still applies to "DO what the manufacturer
says". But I'm open to real engineering answers on this.
