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.

I did not think the big box store grout shrunk but regardless, what is the
purpose. The new tower is sitting on the bolts and they are adjusted so
that it is plumb. Now do you pack grout in under the legs so the tower is
sitting on concrete?

Home Depot has "construction grout." Sakrete or Quikrete brand are
fine, both are rated at 8000
psi or better, depending on how thick you mix it.
Tower specs call for non-shrink grout. Generic construction grout
ain't it.
