Cracked Tile in New Construction Home - Foundation issues?
Your slab has cracked and that it why your tiles are cracking. This is not good and you need to document everything with pictures and get back with the builder to fix this. Check with your Better Business Bureau (or whoever you have) to see about attorneys who could help if it should come to that. Send copies of the pictures and descriptions of the damage to the builder via certified mail. Get this ball rolling while your still under warranty. Good luck.
