Tiles lifting - heated floor

[Manor Jump]

Hi all,

I’m hoping someone can help.

in June 18 we had some tiles fitted to the kitchen and hall, along with electric underfloor heating.

the tiler used insulation pads, then applied the electric matting, and the tiles were stuck to that surface.

We were instructed not to turn in the heating for some weeks , and then gradually increase it by one degree a day. As it was June we didn’t need the heating for some time. It must’ve been about 3 months later before we used them.
About 6 months ago a couple of the tiles started making a hollow noise when walked upon. This has quickly spread. Most of the tiles are now effected, the grout is cracked in a lot of places, and you can even see movement with some of the tiles.

The tiler did return to look initially, but on setting the extent of the problem he’s blamed the heating and is now refusing to answer calls.

I’m keen to see if we can fix this ASAP, before tiles start cracking. I’ve bought some fix-a-floor adhesive after searching For people with similar problems but I’ve not been able to apply it myself as the grout is only 2mm thick.

Can anyone please offer

A) any advice on how to cut holes in 2mm grout without damaging the tiles, and then squirting in the adhesive?

B) offer any other advice on how to fix the problem?

C) be willing to help resolve the issue? ( I’m based in north Manchester)

Any help at all is appreciated

thanks

Hi.

how big an area is it. ?

About 27 sqm of tiles went down. Roughly half is affected, maybe less.

Can you lift one of the loose one and take pics of what's under the tile?

 

[Manor Jump]

I expect one wild come up fairly easily, but I’m worried about leaving a hole in the floor because it wouldn’t be able to get it back down right

You really need to see what's been done under the tile. Are the wires completely covered with adhesive or levelling compound?
Has the tile just not stuck to the adhesive
Your fixing method, if there is one, depends on why its failed.
If the tile is loose clean it and it will go back down fine

As @JulianSidney says we really need to see what's going on to advise the best way forward

Skirtings remained in place.
Ok thanks, I appreciate it’s hard to diagnose remotely, and even more so if you can’t see it. There’s one now that’s “crunching” under foot, so I’ll give that one a try and get back to you.
I’ve got some suction cups. Is that the best way to try and lift it? If I break it I’m screwed as I have no spares.

If it's loose it may well lift with cups depending on quality of cup and texture of tile . But to be honest you're going to need some tiles
