Porcelain floor tiles coming loose

[Gul]

The tiler has come round to take a look. Interestingly the bulk of the tile appears to be firm, just the corners on a few and a few abutting corners. Looks like to adhesive has set firm to the concrete floor but not too well to the tile. The tile I have looked at is pretty clean, so we're a bit puzzled.

My tiler suggests that we clean out the grout of the loose coner and force adhesive or grout down as a first option, to see if we can secure the loose corner.

Anything has got to be worth a try. MY worry is whether the secured tiles eventually come loose.

Do you think that if they are stuck now, there's no reason to think they will come loose later ?

what's a decoupling mat ?

Adhesive was combed on with a serated trowel. The tiler has used expansion joints using a mastic, every 3 metres.

Is the adhesive still in a combed effect on the floor or totally flat under the tiles.?

This is the decoupling mat i use and this is a quote from their tech.



PCI Pecilastic is a separation layer suitable for use under ceramic and natural stone tiles. It is suitable for indoor and outdoor use on all sound and cracked substrates and for use with underfloor heating systems. The PCI Pecilastic layer enables the substrate beneath to move laterally which means the tile above is protected from the detrimental affects, which sub floor movement, can cause. A solid bed can also be achieved due to the flat nature of the membrane eliminating the problems associated with point loading as long as the appropriate tile is selected.

How long once the tiles were laid did the ufh get turned on

bet those expansion joints dont go through the screed....or have the rules been changed?

I know this thread is quite old now but i would say this has the hallmarks of the tiles not being back buttered when they were fixed onto the floor. The tiler should have spread the adhesive onto the floor with the correct trowel depth and also back buttered every tile to ensure 100 percent contact. UFH has nothing to do with this otherwise the tiles would have decoupled or be hollow all over the floor area and not just in the corners of the tiles.

I hate it when people join the forum to ask a question, get info from the guys and then just leave the thread hanging without an update or a thankyou.

I had the same problem with loose tiles in my kitchen, There is a product I used called FixaFloor which is specifically for this problem. You drill holes in the grout around the tile then fill the void with the special Fix a Floor bonding solution which solidifies over 24 hours. once done you just put a little bit of grout into the holes you drilled and no one will ever see that you did anything to your floor!! It solved my problem and now my Kitchen tiles don't move any more! : ) Have a look at the videos on http://www.fixafloor.co.uk they show you how this works
