Hi, my first post.
First just to say hello and that I think this site is really good. I have been looking at it and it seems to be full of really helpful knowledge and advice. I am a customer not a tiler. This is my story so far.........!
We have been renovating an old house and have run into a big problem that maybe one of you maybe able to give some advice as to how we progress from here.
We subcontracted the tiling out to a local company that had done a superb job on a friends kitchen floor, which had underfloor heating too. The work was to lay about 40 sq meters of 80x80 SaloniVisual Crema tiles. The floor would already be prepared as follows;
100 thick concrete over site to BS8500
80 mm thick insulation board, (Celotex was used)
Separating layer of sheet polythene min 125 microns or 500 gauge
Underfloor heating coils for water based system secured in position with proprietary fixing clips. The installation of the coils were laid in strict accordance with the heating engineer's and manufacturer's recommendations and instructions
75 mm thick sand cement screed finish
The floor was left for about a month until the heating was turned on for testing. Then off about 2 days before the tiler arrived. The tiler found that the tiles were really difficult to cut but seemed to do a good job and laid them in about 3 days. He used flexible adhesive. This was about 3 weeks till Christmas. We asked (twice)the tiler and supplier if we could turn the heating on on Christmas day and both said yes, no problem. We started at 16 degs c increasing 1 deg each day until 20 degs max.
After 2 days or so we noticed hairline cracks on about 5 tiles, that had been cut ( the tiler had left an expansion gap) and also upon further investigation about 70% of the tiles appeared to be ’blown’, mostly in the corners of the tiles. Later when we lifted a tile we noticed that the adhesive had stuck to half the tile and half the screed.
We are at a real loss at what to do now. We have arranged a meeting with the tiler and a rep from the adhesive company to try and find a solution, but not being a tiler I don’t want to be bullied into accepting something that isn’t up to the standard that you would except of a £4000 job!
If anyone could give any suggestions I would be really grateful.
Regards AJ47
