Ahh, good question. What you want is NON-shrink outdoor grout - the
stuff for the bathroom is not suitable.
You might be able to find it at your hardware store. Look at the specs
carefully to make sure you've got the right stuff.
I get mine at a masonry supply store. It comes in bags and you mix it
with water. It needs to be pretty stiff or else it'll just run out of where
you want it.
What happens is that the grout becomes part of the support for the
tower base so the stresses just aren't on the bolts.
