 you're just simply going to add some additional floor adhesive and press it back down again. Or you have to remove the whole floor and replace them. But, of course, that's a big job because you can't really save the heating coils that are underneath. You'll probably end up having to replace those as well. It's really hard when you have a bad tile job, especially one that's over heating coils like that, to do anything short of replacing it. It does not lend itself well to repair.
