tiling cracked and movement

[angela3]

tiling was done in kitchen and hallway last july two weeks ago a tile cracked there is movement and clicking noise in centre of floor another tile lifted noi bother and some grout/adhesive on back then another cracked. its a house that is ten years old the plywood they used was 6mm. ceramic tiles 300mm x 600mm

anyone help with this please

6mm ply is too thin, 15mm is british standard minimum.
A few more details may help also, what is the floor made of beneath the ply, what adhesive and grout was used, was the ply screwed down and were the tiles fixed using a solid bed of adhesive? A few pictures may help.

What have the tilers who tiled it said when they looked at the problem

Incorrect prep work using 6mm ply. Have you contacted your tiler yet?

Did the tiler install the 6mm ply?

tiler was through builder as we were getting extension done. he is coming tomorrow to see it but says he never done anything wrong. builder says there is nothing wrong with 6mm and it is not as straight forward as I think

600 x 300 ? more likely to be porcelain. As above 6mm ply is no good.

Angela he should come back and fix it but sounds like he would have to take it up and do it properly but using 6mm ply and priming it three times tells me he isn't a tiler where are you ?

 

[angela3]

no builder

 

[angela3]

Not only have they installed 6mm ply, but they haven't used the solid bed fixing method that should be used with all floor tiles.....

i would insist he gets a independent tiler to look at the job and correct it

 

[jay]

Recommend a professional tiler full stop (real tilers do there own prep work)

If the tiler came through the builder should the tiler not have told him before now 6mm is no good. If he is a tiler.

That is correct ,the tiler has accepted the prep work because he has tiled over it ,so now its the tilers problem :mad2:

 

[mcarthurtiling]

I think it could be a case of ripping it all up and get it done right, sure enough next month it could be another few tiles that crack.

 

[jay]

Its the only way to fix this one ,prep work needs to be done right for the tiles to last the substrate has to be spot on

If it's cracking after 2 weeks then a rip out is in order...

It would seem to be bad prep and bad tiling.
