[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.

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

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
