Tiling failure over wundafloor

[Dumbo]

If you cover my costs i will be willing to take a trip over to take a look?
There must be a few decent tilers in your area?

Is this something you do in between not scoring goals

@andy tiler - They are due to remove the kitchen and take up the floor starting Saturday 24th. Once they start I will take you up on that offer. Track record people are not very reliable and I don't want to waste your time. Thank you very much Andy.

Andy's pretty good but he talks a lot! 😉
(...and check if his van will hold enough charge to make it from Manchester)

Haha behave yourself Andy haha
Simon above is in Maidstone, in fact I think everyone I know in England is closer than you. Haha

I would however be more concerned about the movement you mentioned originally.

The chances of removing adhesive from the Dural matting are slim to none without destroying it. It’s not like ditra where you can chip it clear. It’s covered with a mesh that doesn’t let go.
Apart from a little difficult to use at times it’s a decent product.
These overlay ufh systems are designed to be laid to flat, sound, load bearing substrate.
It doesn’t sound as if your original floor was up to standard if there’s movement and bounce.
Your floor should have been levelled prior the install of ufh.
Levelling over the top will now impact the efficiency of your floor and you may find some areas warmer to the touch than others, especially if it’s different thicknesses of leveller everywhere.
There are other issues attached to Wundafloor, it has an aluminium covering, this foil can react with Portland cement and is supposed to be tiled in a very specific manner, in fact most I know, won’t even tile it at all.
There is a product now sold by Wundatrade, which is a 4mm backer board designed to be stuck over underfloor to negate the chemical reaction between aluminium and Portland cement.

Have you checked to see if the Dural is actually stuck to the ufh still?

Yes @3_fall... thank you so much for such a detailed response! Thank you all.. This site is a life saver... my family are at home in the bloody cold right now with just an oil heater!! looking at me like what the hell is going on!!

@3_fall I'm constantly getting mixed signals. My builders response "I've use Bal on top of this floor all the time and get no problems". Next week I will find out more as they will be taking up a bigger area so I should be able to see if the dural is stuck and if they are even able to get it up without wrecking it! All of the signals i'm getting is I need to start again!!

If there is movement and bounce is the builder at fault for not preparing it correctly. Or is the tiller at fault for tilling over something that was not prepared correctly?

When I spoke to Wunda they said "if I use there products I shouldn't need to use the board". @3_fall in you experience would you still use them? (as I will have to take that cost) if so how do you stick them down?

If only one side of the house seems to have the movement is there anyway to repair this without the floor coming up?

Guys - Is it worth me paying to get the TTA round to do an independent review and will they look at the subfloor?

Again I cannot thank you enough!
