Marble floor tiles popped - Tile Advice

[Ryan walker]

I tiled a floor with 300x600 marble tiles about 8 months ago .
I have just been called and told that some of the tiles have come loose .....
Im trying to assess if i am liable to sort it out at my cost .

The builder plyed over old floor boards and then stuck underfloor heating to the ply and then did a thick layer of self leveling ontop and waited for it to be fully dry for myself to tile . I do remember having to build up the adhesive slightly more one side of the room to keep the floor level.

I used flexible nicobond rapidset adhesive and flexible bal superflex grout.

Did you use an uncoupling membrane?

 

[GoneGuy]

Movement in subfloor? How thick did you build the adhesive up as some have a maximum thickness

A picture of the back of the stone should tell all...

No uncoupling membrane was used as it was the builder that set the floor up i just turned up and had a latexed floor to work with i assumed they would of done there job properly but now a problem has occured i have asked questions how they preped the floor

 

[Dumbo]

What thickness ply did he use . Was it glued and screwed. But he shouldn't of done that anyway , my guess latex let go of floor . Also I agree with three previous replies

Wood floor, UFH, self levelling, soft natural stone (marble) covering - no uncoupling membrane = problems!
Who is liable ........ whoever thought that fixing marble to a heated wood floor without an uncoupling membrane.
Sounds the same and sometimes you just have to walk away from jobs if your not happy with the preparation, but really you should have asked your questions of the builder before tiling 8 months ago!

I am assuming you didn’t use a uncoupling mat, did you spread floor and butter back of tile as well as this makes a huge difference as well.

Ply, underfloor heating, builders prep, building up tiles..dot and dab ?

Not good and you shouldn't have tiled it.

 

[J Sid]

are you liable....yes
should ufh been put on ply...no
should you tile on ufh without uncoupling....no
should you let a builder prep the floor ready for you to tile....only a fool would unless you over see every step and every details done to your spec.
