Removing edge tiles with UFH

[J Sid]

Would be interested to know why the tiles have broken round outside.
If badly fit should come up easily.
I would be very concerned about doing a job like this. What happens if ufh failed 6 months down the road. Finger gets pointed in your direction Timo.

Before you start, i would remove the wires from the stat and take an ohms reading and keep a check as you work. I take it the floor is working correctly before you start. Once you have a tile up you may see where the wires are running.
If you are lucky who ever fitted the ufh would have left wire away from the walls by 100mm.
Take it slow and you should be ok.

Yeah, I did put a multimeter onto the UFH and the existing cable seems fine (100 ohms between Active and Neutral).

They've just had a kitchen extension done so there is a new slab now alongside the existing tiled floor. So these partial tiles were the ones that used to be along the old wall so fingers crossed the UFH is at least 200mm from the wall and therefore not even under these tiles!

So you're tiling the extension? Are you joining onto the existing tiles?

Yes, that is the job I'm looking at. About 10m2 of extension joining into the existing tiles (with the same tiles - which they already have).

The screed (for the extension) was only poured 2 weeks ago so the job wouldn't start till December. And in the meantime I've asked to do some trial tile cutting to see if the approach with scoring the tiles and then chipping them out is feasible ... will report back on that asap.

How are you planning on dealing with the movement, between the two slabs?

i was planning on just using flexible ashesive. No? What other solution would you suggest?

 

[beanz]

You really need an expansion gap along the join. I can't think of another way you can do it, without the tiles cracking.. 😉

 

[J Sid]

Expansion joint is a must or you will be back to lift the tiles over the two different areas sooner than you think. Not always the most attractive things, but a must in this situation.
