About 25 years ago I had a 89' US crankup tower and I installed the mounting 
plate between two nuts of each anchor bolt.  The plate sat above the 
concrete pad and I never used grout.  I never had a problem with this 
installation and I don't understand the purpose of using grout.

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?
