I think we're in agreement on the rest of the issue, maybe the
OP will clarify this point.

After posting, I see where yesterday OP posted this:

"No, he did no work on the tiles that came up. He worked on the tiles
right up to the ones that came up. "

So, I guess your interpretation is correct. I'm baffled as to how
then these adjacent tiles could suddenly pop. My suspicion would
be that the subfloor is not sound, but OP says he thinks it's slab,
so I don't get it.

Actually, here's a question. Is the OP *sure* that he didn't inject
adhesive under the adjacent tiles? Unless he was watching, how would
he know? Seems logical to me that if contractor knows that there is
a problem with loose tiles, while he has ones out that are loose, he
would inject adhesive under any available spots on the adjacent ones.
That's what I would do.

Looking at those photos, maybe there is another angle to all this that
no one has brought up yet. This isn't one or two loose tiles, it's a
lot of them and a serious problem, indicative of a major underlying
problem of some kind. The contractor is supposed to be the
pro and the OP could argue that a competent pro would never have even
attempted to fix this because it was very unlikely it could be successfully
repaired short of full replacement. If I were a contractor and saw
something like that, I think I'd advise against it and if the customer
insisted I try to fix it anyway, then I'd get them to sign a disclaimer
acknowledging the high risk that it won't be successful.

I posted a map that was supposed to be the work that was actually
done. It came right up to the start of the kitchen tiles but stopped
just before the ones that actually started lifting.

Even if warned, I don't know what I could have done but had the repair
attempted. Most of the house is those tiles, all connected. Actually,
in a way, I got lucky - at least so far. The tiles that blew up were
in the kitchen, and that can logically have a separate scheme from the
rest of the house. If it had blow up towards the dining room, or
towards the 2nd bedroom, or the tiles that head around the (carpeted)
living room, that would have been a real disaster. Tiles switching to
a different type of tile could be odd looking. I would probably have
had to redo the entire house.

But this way, we salvage a lot of tiles from the kitchen. That way, if
problems do creep up down the road, I'll have a lot of spares to deal
with it.
