Expansion Bolt installation

I'm curious about this too and as a follow-up, I'm curious about how flat 
and level the floor remains where an anchor rod is installed. I have a 
situation which depends pretty much on full contact between a pad and the 
underlying floor. The pad is secured by two 5/8 anchor rods spaced about 
3 inches apart which support a fairly heavy piece of chemical processing 
equipment. We're looking at 4 pads with two anchor rods in each. Having 
seen some anchor rod installations where the rods missed the holes 
completely, I'm a little nervous about how well this installation would 
work in practice. It's easy to draw, but how easy is it to realize?
