Cracking Tiles

Posted by sgrammer (My Page) on

My house is approximately a year and a half old now and I already have a three areas throughout the house with a crack going through multiple tiles. The tiles were laid on top of the concrete slab without any substrate. I'll attach some photos after this post.

So, my question is: what could be causing the cracking? Is it just normal settling of the house? And if I remove/replace the cracked tiles, will that prevent crack from continuing to the adjacent tiles?

There is one area where I recently pulled up some carpet in an adjoining room and had a chance to look at the concrete underneath the tiles and didn't see any cracks; just in the tiles. I'm not sure about the other two areas.

Any help would be appreciated.

In the picture below, this is the first crack to show. It has widened and lengthened over the past few months. At the bottom of the picture, it follows the grout line to the left and then continues through the tile diagonal from the cracked tile in the picture.

RE: Cracking Tiles

This crack is by the back door and goes through two tiles as shown and then follows the grout line to the right and then down the immediate perpendicular grout line. It stays in the grout and does not affect another tile as of this time.

RE: Cracking Tiles

This crack is the one by the room I removed the carpet. As shown, it bends through the first tile and continues through the next tile.

This photo shown the concrete below the tiles.

Could be voids under those tiles. Try knocking on the tiles to see if there are any hollow spots. Also, a decoupling membrane underneath would have helped. As long as you have some replacement tiles, might just do that and see how it goes.

The last pic shows they had bad coverage with the thinset. Just replace the bad tiles. (Probably will happen with some other tiles over time.)

RE: Cracking Tiles

Thanks for your response. I tapped around each tile and only the one next to the room that I took the carpet out sounded hollow. The other two areas I couldn't hear a difference when tapping all around the crack.

RE: Cracking Tiles

Seems the cracking is on the vertical and not the horizontal.

Don't worry so much about the slab.

The framing is moving.

Cut the grout at the cracks now and see how far it goes.

Give it time to become stable and replace the damaged tiles.

Time is your friend here.

Good Luck.
