What's under the concrete almost never comes up in these discussions. It makes a difference.

I talked to the lift people and they want a minimum of 4" of concrete at 3000 PSI. I have 6" at the post installation points (4" everywhere else) and it's 4000 PSI. I also plan on putting the additional supports on the floor to spread the load out and add additional bolts.
