I have an existing 8'x13' concrete slab that has settled 2" along one side. It is the floor between the house and garage, walled in and covered by a roof (breezeway). It is around 40 years old, has one small stress crack about 2' long. We stripped off the old floor tiles, leaving a light colored glue residue that does come up partially with mechanical scraping.
I was thinking of attaching expanded galvanized wire lath with cement screws every 12", and leveling in a 3:1 sand mix. The finished surface would probably be covered with a regular floor covering, such as vinyl tile. My concerns: will any kind of adhesion to the old slab be essential? The part where it would be most critical is where it's thinnest, about 3/8". At the thick end, it would approach 3". Is that too thick for a sand mix?

Welcome to the forums! Your method won't stop the sinking nor cracking. It will continue to do its thing. Hydraulic jacking and grouting would be the best solution to bring the concrete back to level and should help with the crack once it is in position.

chandler's right all you'd do is add more static load ( dead weight )

for a proper thin o'lay to work, you'll need the right mtls & method + mechanically secure exp wire mesh every 1 1/2",,, the 3/8" area doesn't need mechanical fasteners should you use the correct mtls & method,,, then again, you may have already decided on repr mtls from an apron/vest store & they're not right,,, wrong mtls + incorrect method = job failure
