Hollow porcelain tiles.

[UnhappyCustomer]

Yeah sorry, should have read a bit more before posting. What made me ask that question is, is it block and beam? Solid floor but, often sounds hollow.

Please explain a bit more. When the floor was drilled to relocate the stop **** it was rock solid and in no way sounded hollow. There are also hollow spots on the solid floor (concete floor over solid insulation). I'm just wondering why the hollow Spots appear random and the broken tile has cracked. Would this not be an indication that the tile was not bonded?

Lift a tile, take a pic then let us have a look

Sorry, I would love to do this but we are in dispute with the supplier who subcontracted this work out.

Without a picture we are really just guessing. You say the tiles where not dabbed? A sketchy guess from me is adhesive has started skinning and tiles not back buttered but as I say, it's just a guess.

Is the new part where the problem is and could It be a calcium sulphate screed that has been laid.

Ok, place the palm of your hand on the floor and chap the tiles with your other hand, can you feel a small vibration? If so then it sounds to me like the tiles have not bonded to the floor. In this case I'd start some exploratory work and get a tile lifted to see what's going on.

On a hollow part there is a slight vibration nothing on the solid parts.

No no most is on the existing floor.

I understand, but how would you suggest I address it with the supplier?

I take it I am correct in not paying while there appears to be such issues.

Is there any expansion joints ? , could purely be stress debonding .. Or commonly known as tenting.

solid bed will look like this and dot and dab will look like this

 

[Martyn Leeds]

I think a full story would be appropriate

Obviously you're not wanting to pay someone. But an explanation of the full story might help gather proper opinion.

IMO !

 

[charlie1]

Can you tell us the following,

1:adhesive used
2:was floor primed
3:fixing method, you said notched trowel, yes?

something is certainly not right

I really can't advise you on that mate, I'm just trying to find out if your floor is failing which I think it is

What would that look like?

There doesn't appear to be any breaks in the pattern. Which is random with no straight lines indicating an expansion joint.

What's the dimensions of the tiled area?

Your questions can't really be answered without lifting a tile to find out what's going on. It's a bit unfair to try and get one of the guys to commit to saying you shouldn't pay as nobody really knows what's happened, only you can decide that one. i would say a tile needs to come up, until then your doing the preverbal into the wind.
