CRACKED FLOOR TILES

GALWEGIAN2015

I noticed cracks appear on our hallway floor tiles yesterday. The crack is in a roughly straight line along 7 tiles, from one wall to the other. The tiles are ceramic. We built our house almost 2 years ago. The tiling was done on a concrete screed floor. Any idea why this is happening? The guy in the tile shop said it is the concrete floor underneath the tiles, that the tiling was done before the concrete got sufficient time to dry out. All help appreciated, thanks

How long was the screed down and how long was the heating on before you tiled the floor? Also, what time of year was the screed put in? If you know this it should give you a good idea. Also, did the tiling test the screed before laying, most do.

Did you lift the tiles to check to see is there is a crack in the concrete??

No I haven't lifted the tiles yet until get new ones. The screed floor was put in in July 2 years ago. I think maybe 6 or 7 weeks later tiling was done. As far as I can remember the heating wasn't even put on beforehand.

Hmmm I think the concrete screed needs to go through at least one full heat cycle before tiles are layed on top.

Is there under floor heating..?? Id like to think that the floor was off level and the bed adhesive was to thick.. but you wont no till you lift the tiles.

Screed with UFH needs to dry out at least 4 weeks then for a week or so, raise temp 5degrees everyday till 25 then reduced it 5 then your good to go for titling

If you let us know where you live you may get lucky with a recommendation (by PM of course....).

Your best option is to ask neighbours, or check with local tile stores to see who they know/recommend.

Hi duckcfc, I got one quick question for you:

At the stage where you 'reduce it by 5 then your good to go for titling', should you:

(a) lay the tiles as the heating is at 20 degrees and ***ensure to maintain the 20 degrees when laying***

(b) lay the tiles as the heating is at 20 and ***don't worry if the temp rises or falls***

Thanks,
J
