I have some questions regarding reinforcement of garage slabs adjacent to poured concrete basement walls.

I am planning to build a retirement home with a three car attached garage. Two of the garages will be used as a shop, the other for a car. Construction procedures I plan t0 specify:
1. Insulate all garage slabs with 2" thick ESP foam board (R-10) + add 6 mil polyethylene under foam for moisture barrier.
2. Will specify re-bar grid in slab to prevent cracking + install side expansion bars adjacent to each garage slab.
3. Should I also tie the slab into the poured concrete foundation wall using rebar....or should the slab be free to float? ( Frost line in area (Bucks County PA is 3 feet)
4. Should I specify "air entrained" concrete for both the slab and the basement walls? I understand air entrained concrete limits cracking and possibly increase the R value of the 4" concrete slab and/or the 12" basement walls??

Thanks, Bob
