Ultra thin porcelain tiles de bonding

[Deleted member 52728]

Evening all, a question for all you tiling pro’s please
I’m an old school plumber & bathroom fitter of over 35 years in my mid 50’s, self employed with a brilliant reputation, never been limited company and never had professional indemnity insurance, however,
I’ve got a problem where there are possible de-bonding issues of ultra thin large format tiles that were supplied to me on a job undertaken a couple of years ago.
The tiles were 1200 x 600 and supposed to be from 4.8mm to 5.5mm thickness, according to the packaging and the companies website, however a TTA report states within their report that surplus tiles were measured with a digital calliper @ 3.81mm, Which is between 26% to 45% less than they should have been.
When I first contacted the tile supplier (client chose & bought the tiles not me) and I told them that I had 3.8mm tiles, he immediately said that they couldn’t be theirs & probably from one of their cheap competitors. He said to avoid them as they will be brittle and likely too flexible with possible de-bonding!
The TTA report doesn’t make any further comment about the tile thickness & I am currently being sued for a vast amount (50 times what I charged) to strip everything and replace, when it seems to me that if the tiles supplied were not as described, they could possibly have been not fit for purpose? And as such the issues that have since arisen may be down to the tiles rather than the fitting.
I used Bal flexible fibre plus for the walls and Bal PTB for the floors together with Ditra matting, which I’ve used dozens of times before on floors & never had a problem
TTA say a tap test suggested large voids beneath all tiles (floor & walls) although Schutler, who make Ditra 25 say that their product can sound hollow when tapped.
Any thoughts please as I may loose my home because of this TTA report!

any photos?.... now there is an official report, be careful what you write on these forums.

Also, you need to tell us, exactly, what your fixing method was - not just what adhesive was used. (it will save many repeat questions from different tilers)

They can't just sue you for the cost of doing the strjp out and replacement , you have to be given the opportunity to correct any faults in your work . I think you will find it's the law .

Thanks for your replies.
As for fixing the tiles with the floor, new replacement floorboards were screwed (as original boards were rotten) then 9mm plywood screwed every 150mm, Shutler Ditra matting laid onto ply using Mapei VS90 latex then tiles laid onto the Ditra using Bal PTB pourable flexible tile adhesive. Both Bal adhesives and Shutler say this process is perfectly good and to my knowledge is in total compliance with BS 5385 although I believe this standard was updated 30 June 2018, two months after I left site.
As for the walls, I was given (at the last minute) Areogel magnesium insulation boards ( designed by NASA!) to fit directly onto the outside walls to tile upon, which I have since discovered by the manufacturers that I was given the wrong fixings, other areas Aquapanel was used throughout. Bal flex fibre plus adhesive was spread onto the wall & back of tiles.a tile levelling clip system was also used to prevent lipping, especially as the tiles were slightly flexible!
I had never before come across these ultra thin tiles or the insulation boards and made my client totally aware that I didn’t want to get involved with the both as I had no prior experience & didn’t even have a big enough tile cutter but the client persuaded me to undertake full installation saying he had every faith in me. I agreed on the basis that I was merely an installer following his instructions.
I undertook 3 bathroom plus a separate toilet over a period of 8 months and everything looked great. No snagging at all.
It was only because the client failed to pay my final invoice for over 6 months without any reason why, that I threatened legal action & eventually took out a online county court claim that suddenly he counterclaimed for a massive amount through solicitors claiming everything undertaken was faulty, including a new boiler installation was undersized.
I’ve employed my own expert witness that totally trashed his expert report about boiler undersizing but I cannot find a tiling expert witness anywhere in the uk prepared to challenge a TTA report, which incorrectly assumes numerous facts.
As for being given the chance to rectify issues, I have always stated that I am prepared to do this but the client has got it in for me as I had the cheek to sue him and refuses to allow me to return on the grounds that I do not have the requisite skills, despite the fact that he knew full well before starting that I had never heard of these tiles let alone fitted them but still wanted me to do 3 bathroom installations including the full wall & floor tiling because I was cheap.
I was suing for 4K unpaid invoice, he is counterclaiming for over 160k plus costs which could be between 50 & 100k on top.
If someone had told me 2 years ago that this could happen to a professional tradesmen, I wouldn’t have believed them.
The fact is that because he is wealthy and I am not, he knows that I cannot afford to pay solicitors over £300 per hour for months on end (Barrister even more), so I will be forced to settle before trail (money I don’t have) as the costs rocket even further
I’ve already spent over 20k on solicitors & expert & cashed in my pension to pay for costs. It’s made my wife & myself quite ill.

 

[Dumbo]

What incorrect fact are they assuming ,

 

[LM]

It reads like you’re being bullied to me!
If all you say is absolutely correct I can’t see a judge finding you at fault, they may say that you ultimately took on a paid for job without the necessary qualifications but then you could hopefully prove that you made that absolutely clear and that honesty and good intention should stand you in good stead.
I’ve been involved in high court proceedings regarding construction as a claimant before in Ireland, it’s a stressful scenario for sure.

Ring Judge Rinder......he will back you up no problem.

Seriously, either your solicitor is thick or you ain't telling us the truth.

Law states you have to be able to rectify the problem (if there is one) and for the sake of £1800 against maybe £50 - 100k ......get your own TTA report done if you are that worried.

If Schluter and bal both said your method of strengthing the floor was ok you should get that in writing from them , that will sink that one as bal I'm pretty sure help come up with British standards . Although I would be pretty sure 9mm ply is not mentioned pre 2018 , but you are doing it inconjuction with ditra25 . I would think with a tile that thin that the tile company would not be happy about point loading on top of ditra 25 but you have not mentioned any issues regarding that .

 

[Dumbo]

And who is the tile manufacturer .

 

[Old Mod]

This is not going to go down well then.
Schluter will not guarantee ditra 25 for thin tiles under 5.5mm thickness, it was 6mm until middle of last year when it was reduced to 5.5mm.
Who from Schluter said their product was suitable?
Don’t mention a name, just their position will do, is it in writing?

And who is the tile manufacturer .

Theres only one GENUINE supplier of these tiles in Uk, I believe he has a few outlets, but there’s only one genuine importer.
Do not mention names @jcrtiling
