I'm hoping for some professional advice on what to do with my new Limstone tiled floor - I'm at my wits end!!
I had a job carried out in my house by local a tiler which completed 1 month ago - Sept '12; details as follows:
- New build house that we've lived in for 4 yrs since new.
- 40 sq mtrs across 3 adjoining rooms - utility, kitchen, family room.
- Exisiting floor is a floating subfloor on a concrete slab - no joists, rigid board insulation, 18/22mm chipboard and 5mm ply
- Vinyl was lifted, existing 5mm ply left down, 9mm WBP far eastern hardwood ply on top, screwed with 30mm screws at 6 in centres by experienced joiner - floor felt very solid after this work..
- Floor sealed and prepared - rolled on acrylic floor primer.
- 21sq mtrs of electric underfloor heating mats laid and installed by qualified electrician - work fine.
- 16 bags of BAL rapidset flex adhesive and 4 x BAL flexible grout.
- Tiles are limestone 400 x 600 x 12 good quality.
- Tiles were quite wet going down - moisture meter read 30-40%. Tiles have been grouted and sealed.
Even over the weekend cracks appeared in a number of places mostly around corners but some along long edge even across adjoining tiles. UFH had not been turned on at all at that stage and was not for 2 wks. Some tiles are visibly bouncing when stepping on edges by 1mm sometimes - looks like the bond is not good. Tiler is well regarded and experienced but stumped. Is looking to put it right thankfully but now 1 month on and no sign so very concerned.
No tiles lifted yet. UFH has been turned on now and is not materially worse for it.We are facing a rip-up and redo. Tiler says his insurance won't cover it.
Not sure what to do - tiler blaming substrate, joiner believes this to be fine, afraid of damaging UFH - not sure about how a repair will go. I've paid for all materials circa £3K - I am withholding labour payment until job put right.
Thanks All at tilersforums,
