Cracked Stone

[Jimpad]

I put down some Natural Stone Tiles 40,00cm*60,00cm from Topps Tiles with Bal Natural Stone addy just before XMas.
About Five or six of them now have a hair line crack running down them.
I think the problem is that, the wooden floor sagged alot in the middle i compensated for this with 12mm ply but around the edge at the bottom of the units the floor was still hight so i couldn't put them Brick work like i was asked and had to make most of it up with Addy..i remember doing 100% coverage but the fact remains that i have a pile of expensive (£10 a tile)Tiles cracked the client wants me to try fixing them first as she really likes them..to that end i contacted the Topps shop were she got them they said their is a poxy resin that might fix them.
What do you all think

 

[doug boardley]

are the cracks in the same place on all the tiles?

How thick was some of the adhesive under the deepest part of the floor

 

[medlar]

you say you compensated for the sagging by overboarding,but did you also make sure that the floorboards were screwed/nailed down securely?

Their is a line of cracks on four of the Tiles but two have cracked on a place on the floor were the floor should have been sound.

About 10/15mm in the worst parts

The floor boards and the ply were very, very securely screwed down.

Thanks for your interest lads have any of you heard/Used the proxy resin i mentioned.

 

[doug boardley]

I haven't sorry Jim

How big was the floor? did you allow for expansion joints, has it cracked along grout joints or just the tiles, is there their any sort of ufh?

This could also be down to lateral stress and not just deflection......

Did you leave a gap around the perimeter of the room in the ply and the tiling....did any joints in the ply land on joints in the floor boards....and building up adhesive is not really a good thing to do on a timber floor with a soft stone like travertine...

This is where lack of experiance comes into play and incorrrect prep work....

IMO the epoxy resin will not work...it will just crack again....you need to cure the problem not just mask it..

Thanks again Lads for the replys
The Kitchen floor is only around 6m2
Im, not perfect but i know that the ply was put down right and the cracks appeared well in off the edge.
I think that Dave is right on what he is saying about the P R but she wont let me just take them up, till i try and mend the cracked one as i have said before the floor came out really nice and i only found out about them because i did a follow up phone call (She thinks you can harly see them)
What i want to do is take up the Tiles and put some self leveler in the part that is low as i think it is the movment in the parts were i had to use extra Addy that has caused the cracks.
I might now be as experinced as some with stone but i wont get over that by reading about it in books.

It could also be the tiles. There has been an issue before with some naturals stone tiles from Topps especially their modular one they were selling as the stone was so soft that a lot of packs had cracked tiles in the packs in the end think Topps senior managment were telling thier managers to stop replacing the cracked tiles and tell customers it was a feature and that they just matche up broken parts.

Did you tap tiles to see if they had a hollow sound because if they had a hollow sound this could explain the reason for cracking.

Thanks for the reply Highlander
I did not check the Tiles before i put them down as truth be told i would not know what to look for.
But i did sound out the guy in the shop about the Tiles and right away he went to get the manager and then came back alone looking nervous and when i pushed him about the Tiles he tryed to blame the Bal Addy.

Thats one of the resons i asked about it on here to see if something like this had happened to anyone else.
And to find out about the Poxy Resin
