Do you seriously think we'd point the finger without first checking every avenue?
Tom you disappoint!

 

[Old Mod]

Who do you suggest is at fault then Tom?

Not really, I am only asking questions.

As I have said, I have never laid on the foil faced boards but I do know what clients and manufacturers/builders/shops are like for pushing the job on or materials to be used etc without doing their own due diligence on the subject.

I, for one, am glad you have brought this to the attention of the tilers.

Hard to say without knowing the tiler's constraints on the job.

I am sure you will understand.

Maybe if you had explained your thinking in the first place I wouldn't have been so incensed at your question Tom.
Fair enough.
Believe me, we have researched this to death, left no stone unturned.
We have spoken with every tech department concerned, there is only one conclusion, it's an install error unfortunately.

How many tiles you replacing ?
If it all going to fail are you not just put a sticky plaster over it....

So now that the foil has had a coating of adhesive and the chemical reaction has occurred is it that, for want of a better term, it's all burnt out and it has nothing left to react?

Yes

It seems very hard to understand this when you beat around the bush when somebody asks you question

Bout 10 Andy, yes quite possibly.
All the indications are that it will ultimately fail, but you know how it goes
"I've been using hardboard on my floors for 20 years, never had a problem!"
Sometimes that's true, sometimes it's not.

It's not been down very long Paul and aluminium is still visible in places, and everything we've read would suggest that it will continue to react until either the aluminium or cement has been removed.

This reaction is actually used in a controlled way in certain circumstances.
Heavy machinery supports for example, when the support legs are concreted in they use a grout made up of cement and aluminium powder.
When the elements react and the expansion takes place, it fills any voids remaining in the concrete.
