Hollow Sounds and Space under edge of tiles?

[Chris101]

Is there more to the story as to why we are questioning everything? Previous form perhaps.
I'm guessing the tiler is an employee of the builder?
'Cos otherwise, any tiler would be seriously questioning the procedures from the builder

Questioning everything is based on previous experiences and as we are having our whole kitchen renovated and putting a new expensive kitchen in, we want to try and make sure that all correct methods are carried out (the tradesman had missed things out when it has come to the wiring and pluming due to not following the plans we had printed out and left for them and subsequently we had to walk them through to make sure nothing was missed out).

The Tiler is subcontracted by the construction company

To be honest if it is a builder you are using I would of got them to replace the concrete floor and then either project manage the rest of the trades yourself or get the kitchen company to do so .

Given the fact they were being filmed etc you'd have thought everything would have been followed to the letter, yet it would seem they couldn't have done much more wrong with the job..

The attached pictures are of the finished screed on the concrete floor with UFH.

The flooring itself has been done by the same construction company.
Initially we had suspended wooden flooring, which they got rid off to put concrete down - the whole area is around 40m2

Filming every tradesmen !!
What's the world coming to.
Don't know about anyone else but that leaves a funny taste in my mouth..

yes i am with you on that point. i think i would have refused the job .

How come they didn't put an uncoupler down if it was in the spec?

 

[dave l and l]

have you asked them why they have not decoupled even though it states it on contract
by the sounds of it your builder is maybe cutting corners a bit

Not sure, apparently it was no longer required and they will explain why tomorrow when they meet us on site...

Well that would have at least taken the issues of the screed cracking and not being 100% dry away...

Can the uncoupler be put down on Wet Under floor heating?

 

[Spare Tool]

Yes, long as its sealed between the runs

 

[Spare Tool]

Oh and as long as its Dural ci mat or Ditra, not just a crackmat

 

[Flintstone]

On a not dry screed I think you mean. S2 is required I think. I'd use ultimate

I can see the tiles will be lifting up in 2-3 months bxthe fixing it is wrong
Make the floor level and backbutter the tiles and lay down rapid matt bal
