had a groundworks chap round recently to look at laying a new garage floor in my existing single garage. The garage is not attached to the house, is built of brick and I believe the walls are constructed on the floor slab. He has stihl sawed round the inside of the garage and removed the floor, back filled with hardcore and wacked it, ready for a dpm and 4 inches or so of concrete. The floor was originally a DIY job, a lean mix in his opinion. My concern is that the brick walls will now be sitting on a thin strip of concrete. Does this need tying into the new internal slab and how can this be none? I'd thought of drilling through the existing strip of concrete from the outside into the new slab and then putting chemically anchored rebars in it.

Have a dig around the outside and check the foundation depth.
If it is as you suspect you really are in a bit of bother. If the concrete is sub-standard then no amount of rebar is going to stop it settling and cracking.
You would be better off underpinning the wall, but if it's only single skin it will probably be easier/cheaper to knock it down and rebuild it properly.
