We have recently completed an extension to our existing house and opted to go for 60x60 polished porcelain tiles in part of the old and all of the new House.
They were installed in October last year and underneath is a piped UFH system. The UFH system was commissioned about 6 weeks after the tiles were laid.
An incident happened where I turned the thermostat off after the floor had cooled about 10 degrees and just turned it back on without thinking yet would affect the flooring.
Slowly the tiles have started to pop/burst/move slightly. Whilst on holiday we asked the tiler to look at what was going on with the flooring, he states that he pulled some of the tiles up and the adhesive wasn’t stuck to them, not only was it not stuck to the tiles it wasn’t stuck to the chipboard either.
Can anyone advise why this is?? The make up of the floor is as follows:
Joists 300mm apart
100mm Kingspan between joists
Plated pipe UFH system
22mm chipboard
Primed with PVA/water mix
Ultra tile fibre fix fx powder mid adhesive
Porcelain tiles
Any help would be appreciated.
Thanks
Gemma
