Buckling ceramic tiles

Or a sink hole?

Under the slab? It's very rocky so I think it would be unlikely but we're going to get an inspection done regardless.

Thanks!

It's unlikely tiles will "buckle" however the underlayment is likely the problem. Likely those tiles are not on concrete but something more prone to shrinking and swelling.

I was wondering about that because of something I was just watching on HGTV (I admit it). They were talking about the backerboard they were going to us.

I think the only way to solve this is to pull them up to see what's there. If we buy it, we'll do that anyway. Even in our house where we live now we have painted concrete floors and I think that would be ideal at a lake house.

Thanks, folks!

Underlayment might swell, causing tile to shift. Tile obviously will not buckle, it might crack. Photos might help, and if there is a major problem with the slab, there likely would be cracks apparent at the perimiter.

But if they are buckled up, shouldn't be too hard to remove them all. 45 degree angle and a running start. Might be a bit harder getting that goo underneath off and level. I've used the "ice breaker" for just this purpose...
