Jerboa Tiles - New Floor Hollow but no tiles cracked -

[jinx4645]

A qualified tiler fitted the tiles. HE also did 7 bathrooms very well for us. He came recommended and also he has over 20 years experience. He suggested that buttering in his opinion was not required. I have also taken other tiler references who concluded the same. Seems that the tiler is partly to blame as the tile / floor may have worked against him. The issue now is how to resolve a mess not of our making to ensure that as a consumer we get what we paid for.......

I agree with the TTA report, tiles should have been back skimmed for full contact...

Just a quick question, did you re-heat the floor as you did when first commissioning the screed, as heating the adhesive too quickly could shock the tiled installation.

You have to commission the adhesive bed as well..just a thought.

 

[jinx4645]

Yes we commissioned the floor post tiling very slowly.......but again had no guidance from anyone but we were sensible in our approach

We also have a control area where no UFH was applied and this has some 80% of tiles sounding hollow. Not sure it has anything to do with the UFH as the control area gives us the clear proof.......

I'am not sure if you would have any recourse with the supplier as to any installation procedure and I'd assume a tiler with that amount of experience would know that tiles of that size should be fixed with a solid bed method.
Again I'd ask - were the surface of the tiles sealed before/during/after installation and were you aware that the tiles you purchased were from China.

 

[jinx4645]

No we thought they were from Italy! Also nothing was selaed before or after.......

So the title is Jerboa tiles - I've not heard of them, but how do you know you bought the tiles you saw on display at £x for an Italian 600x600mm porcelain and were supplied Chinese 600x600mm porcelain at £y which could have been about one fifth of the price. There are threads on the forum with reference to large format porcelain from the large DIY sheds with 1000's of comments!
This reply is more about the surface discolouration problem and the fact that the Retail DIY outlets insist on instructing customers to seal their porcelain tiles.

All thanks for responding - as with all of these things therecould be a number of contributing factors and my research is inconclusive as is outlined in this thread. If anyone reads this who is a consumer. Be careful your investment in the floor is a major one - supply companies generally supply tiles but not installation information. Its like buying a car without a manual. Certainly the Jerboa tiles we purchased are sub-standard on one level (the discolouration) and the installation issues add further insult to injury. Please only post if you have any pearls of wisdom but at this stage we will take our gripe off line and see if we can reach some sort of agreement to resolve the nightmare.

when you lift the tiles is there any moisture on the backs of the tiles or are they dry? also do you know if the new screed was primed before tiling commenced the tiles ,you call jerboa are also called Molise and are distributed by several comanys they have holes on their surface and look like a travertine tile, the discoluration can be cleaned off with professional cleaning but it is difficult, the kwik flex is walls and floors own brand of adhesive it is manufactured by Palace chemiacls I believe,do you have the batch numbers for the bags used?

Each tile came supplied boxed and ready to fit (according to the supplier). There is a dust residue left on each tile, apparently linked to the kiln process, which is quite usual - apparently. This was not cleaned on each tile and is still present on the lifted delaminated tiles and does appear on the dry adhesive still on the floor.

Is this dust loose or stuck to the tile.

Could also be tat the adhesive has started to set or skin before the tiles were placed. Was the screed primed at all?

I have a pearl of wisdom. Speak to your home insurers about sticking in a claim. You can foward them the TTA report and everything else you have gathered. Let them pay for it to be replaced OR, if they believe the tiler was at fault, or the seller of the tielrs, or the pourer of the floor screed, then THEY can take it up with the insurers of those parties and you won't have to do all this running around and detective work.
