Tiles making crunching noise. Can't pull them up help!

[Alan M]

i presume you mean you dont want to pull them up.
i would pull out the cooker ,fridge, washing machine ect. and pull up one of the tiles there. that way it wont be seen.
if the tiles are sounding loose then its only a matter of time before you have a total failure and are forced to replace.
the tiler should stand over it

When you fix porcelain tile you always trowel adhesive to the back of the tile. This gives rhe adhesive a good key to stick to. Its also called back skimming. Deano and ajax raise a major point here, what was the screed made from? Was it a cement screed or was it self levelling Anhydrite???

 

[Charlieb]

Self levelling screed.

What type was the self leveling screed.....

My money's on insufficient bed thickness and tiles not back-skimmed.
