quarts floor tiles warping

[trustiling]

This happened to us on a job about 4/5 years ago with wet underfloor heating in a new build, few months later tiles all curled like quavers.
Lucky for us it was in a builders own house that we do plenty of work for and we weren't out of pocket.
I won't lay 600 x 600 quartz now full stop.

Which adhesive was used ?

as a builder we carried out all the prosses correctly up to our tiler laying the tiles when the engineer came out to inspect he noticed there was a couple of areas where the tiler had dot and dabbed a few tiles even though the problem is all over he blamed ourselves for the way the floor was tiled if this was the case it should only have happened where the tiles where incorrectly fitted ie dot and dabbed I know these tiles should be on a full bed of adhesive but this method is sometimes used to level out discrepancy's by tillers
the tile supplier has confirmed the adhesive and slc where compatible ?

None of the tiles should have been dot and dabbed. Like you say, this has happened to tiles laid with a notched trowel too. Your tiler should have known to back butter floor tiles! This still would not have stopped the warping, but the bad installation gas given the supplier a get out of jail free card!

Not our usual stuff now I think back, it was what was recommended by the supplier can't remember brand unfortunately but it was enough to make me walk away from anyone who wants then laid or talk then into something different.

Doesn't inspire confidence in your record keeping if you cannot confirm the adhesive used. To present a case you need such basic information.

Hold your hands up to the dot and dab.

Get confirmation, in writing, from the tile supplier that the correct adhesive was used for this installation ( quartz resin tiles on a heated screed)

Then surely, by stating this, they are also confirming that the tiles were ok for this installation. Otherwise NO adhesive would be correct!

If the tiles are curling up, I can think of no other element that would cause this other than the tile/ufh combination. Even if the tiles were poorly fixed the tiles would simply de bond, not warp.

I have laid 100's if not 1000's of sq/m of quartz resin (a fair amount was probably the cheapest the customer could find) on heated screeds and electric ufh , and never had a problem.

Could it be a dodgy batch?

Never had a issue selling Gulfstone Quartz......

There maybe a reason they are a bit more expensive......

Also use an S2 adhesive (such as TileMasters Ulitmate) = no comebacks
