Nah definitely not. Thats the 1st thing I checked when I saw it.

Ok so its back to the drawing board. I've just spoken to the architect and apparently it is a floating floor. He said the joists are 200mm apart. What are my options?

Is there much movement in it?
Consensous is not to touch them but I have tiled to floaters as they have been quite rigid without problem.

It certainly felt solid when I walked on it. Customer said it wasn't floating but architect confirmed it was.

If it's floating it won't have joist just chipboard over kingspan.

Hi Dave. Check for deflection if really bad walk away there are some horrors of floaters up here. If you must do it the way I did one a while back was 10 mm marmox glued and screwed heated then screeded then ditra tiled with a decent 2 part. I was back at this property to do there bathrooms and all was good but it's a gamble. I only did it after stressing if ther was a failure I would not be held responsible. The garuntee only lasted till I walked down there path and into the van.

I'm confused now. Architect definitely said the joists were 200mm apart. Is a suspended floor the same as floating floor? This pricing malarky is harder than I expected haha.

No different

I looked again & noticed that you said the joists were 200mm apart, strange make up even if it's a suspended floor, normally 400mm apart even if they are trying to strengthen the floor knowing its to get tiled.
