Travertine floor tiles breaking into holes after few months of being laid Advice and information on tiling and fixing tiles to a variety of surfaces

CAN ANY ONE HELP
a customer of mine had some travetine floor tiles laid in February ,and they are now breaking into holes.......... I didnt lay them and we'd like to know why :?

Sounds very much like they have been laid on an unstable (wooden?) floor. If the floor moves in any way the tiles will either crack or move with the floor which means the grout in the joints will crack and form holes. There is no way to overcome this problem except to strengthen the floor. It could also be that the floor has been laid on a bed of adhesive which is too thin and consequently is not supporting every bit of tile. If the tile wobbles the same symptoms will occur.
