This is an interesting thread which has similarities to problems i am having.
I mostly work for major housebuilders and have had these problems on wooden floors.
I would be interested to know if,when you lift a tile you find that its fixed well to the matting and you are left with just the fleece from the back of the matting stuck to the adhesive which is stuck soundly to the screed,in other words the matting itself has separated.This seems to cause the crunchy sounds.
We have multiple failures and can only conclude that the problem is either the matting itself has failed,or excessive movement has caused the matting to fail.
Dural do have a system to solve the problem if separation has occured between the fleece and the plastic upper.
Hope this helps.

This is correct Dural are coming to look and hopefully fix my problem but it does put a little bit of doubt on using this product again ? It has happened twice to me now

thanks for the update just wondering who made the call to rip it up

We did - the whole floor is now affected, and the only way we can sort is by starting to take it up. I have a tiler blaming the screeder and a screeder blaming the tiler, so both will be here. We think the dural has uncoupled from the screed, but we don't know why. Until we do, we won't know what we can do to fix it. Hopefully, we'll get some answers.

Have you contacted Dural ? I can see an ongoing argument between screeder and tiler and no one will ever find the true answer.

If the tiles and the dural come up clean away from the screed leaving the screed completly intact I would suggest tiler error.

If when the dural comes up you get lumps of screed attached to it then I would be screeder error.

I have only seen Dural delaminate on a couple of occasions, once where the screed was simply too dirty for the adhesive to stick to it and once where the adhesive failed to set (dispersion type used)

Installation issues with the screed could include Lack of compaction, lack of cement, mix too dry, mix too wet, Mix over-retarded, screed not cured properly. All of these will manifest them selves similarly with a weak friable screed.

will leave the tilers to comment on potential issues with the Dural installation.

What if the primer used was PVA, would it sweat underneath causing it to become 'live' again?
