Limestone floor cracking.

[pollybampton]

Hi Doug, No is the simple answer. I have never heard of what you have suggested, and nothing of the kind was even hinted at by any of the people involved in this fiasco.

it sounds like deflection to me, there'll be a lot of weight on the floor now, was their any noggins or bracers put inbetween the joists prior to the ply being fitted Polly?

no no, my user name is a twist on my real name. Glad to be here and having some interest shown in my predicament.

longshot here is it bampton in oxfordshire,?? i used to live in oxfordshire or am i talking tosh polly, oh welcome to the forum!!

OK guys, lots to ponder here and photos are needed to help diagnose this problem. I'll have images on line by tomorrow evening, children's bedtime permitting. The floor should have been cleaned as well by our cleaner, so shouldn't show me up. I'll contact the floor company to find out the type of stone and the thickness. Original quote was for Fiorito Travertine 610x457x10mm but they couldn't get this size in time for me, they only had 457 square.
Limestone was then chosen at 10mm thick. If thickness is an issue here, I'll point out just now, that we have only followed advice given to us by the people involved.

Too many guesses without having more info. Pics would be good showing the pattern of the cracks, not just a close up of a cracked tile, Do the cracks seem to follow a pattern of the boards laid/

I agree with the decoupling membrane though.

What I dont understand is the comment about the flooring company not being able to get Travertine....? the most common stone around IMO ?

Evening all,
I have a few images of the limestone tiles showing the cracks. There are some single images, and there is one long image which I've made up ( very roughly) from a series of images. This long image shows the extent of one of the cracks and the line that it follows. Just hope I can do the attachment thing.

here's the long one

Ok.. that confirms deflection stress.. not alot will fix this issue as it is.

 

[pollybampton]

Hi Dave, What is deflection stress? What causes it? How could I have prevented it? Does it happen with all tiles? As much info as possible would be helpful and appreciated.

[doug boardley]

it's caused by the joists moving Polly, akin to tiling a trampoline (obviously just an analogy)

this is a difficult one if they are all playing the blame game and you will have to go legal on them

if you employed the tile shop then you will hare to go after them, its the tilers responability to check the subsrtate is suitable and advise the client if it isnt, your legal advisors will be able to advise you on this

No cure for this apart from ripping all the limestone up,all the ply and checking the subfloor and most probably strengthening it thoroughly. The ply can be relayed then a decoupling matt stuck to it prior to new tiles being fitted.A very costly repair/replacement if you wish to go this way,pity you can't hit someone's insurance !
