Thoughts on this floor

[stusgsx]

Hi guys. Went to look at a job this week it's a kitchen and diner the dining room is new extension with chipboard floor and old kitchen is concrete. It has been tiled through but the dining room floor has failed. My guess is the builder went straight over the chipboard.
Not sure how to sort it really. They want the same tiles to match again and the same level and don't want to rip the kitchen tiles up either. Only way I can think of is to take tiles up in dining room and ditra mat but even that will take floor height up.

Is it a floater?

 

[stusgsx]

Ooh not sure actually. I will have to find out. If it is then I'm swerving it!

I've covered chipboard once with Ditra & tiled & got a call a few weeks ago to say a bit of grout has came out.
I wasn't keen on doing it this way to start with, I haven't seen the floor yet but will get a look next week or 2.
I'm not going this route again..

Could be the reason it failed. .

I probably would go down the ditra route too. I'd then separate the 2 substrates with a schluter trim to hide the height difference.

 

[stusgsx]

They don't want any trim separating it and it is opus pattern so might look odd. Don't think I would like to guarantee it just over ditra :-/

Y don't you call bal and speak to their tech department on their cracking mat as it's very thin and that would take out the height issue. See if they will guarantee it on chipboard and then use a 2 part addy.

Tilemaster have a matt , under 1mm thick, used it the other week , good stuff

Why is the original tiler/builder not sorting it out. You have two separate and distinct substrates with significantly different movement profiles. There should be a joint between the two full stop. If you don't and it fails again, (a quite likely scenario) you'll be crack repairing it again.

Ajax these people have just moved into this house so think it's been like this a while and they are doing the place up. I think I will tell them I can re do it but can't give a guarantee

Ah I see. If you redo it you have no choice but to give a guarantee. If you do the job and it fails you could find yourself having to go and redo it again. If it is not guaranteeable then dont do it.
