Hi looking for advise regarding cracked wall tiles on an internal wall. I had a new bathroom installed with the bathroom being fully tiled. A few months after work finished I noticed cracked tiles at the window. The company came out to inspect the tiles and said they had never saw anything like it and retiled, replacing 12 tiles in total, however after a few months the same thing happened. This time they said it was nothing they had done and suggested there was some movement in the wall. A structural engineer came out and confirmed there was movement in the wall. However apart from the tiles there are no other signs of movement on the other side of the wall or downstairs. When I removed the tiles I noticed it was only the glaze on the tile that was cracked, the grout wasn't cracked and the wall itself had no cracks. The https://www.tilersforums.com/forums/tile-adhesive/ gets thicker nearer the window as if the https://www.tilersforums.com/forums/tile-adhesive/ was used to build out the tiles to keep the wall straight (I have enclosed photos) is it possible this is the cause of the cracks. I do not know what https://www.tilersforums.com/forums/tile-adhesive/ was used but the tiles are saloni. Look forward to your comments.
