Natural Stone Flooring Advice - kitchen problem

[doug boardley]

it sounds like a dreaded floating floor.....if this is the case, not a good idea at all to tile onto

Sounds like a floating floor to me. Not generally considered good for tiling to. Certainly not a good idea with natural stone. The pro tilers might be able to give better advice here. Do you have any flexibility in terms of floor height. if so you could take out the caberboard and put a screed in its place.

Doug clearly types faster than me......

If that's the case I guess the only solution would be to replace the floating floor with a decent floor capable of taking tiles? Any idea how big a job this is? It's odd that Hopkins Homes put in floating floors and then allowed us all to spec tiled floors when we purchased them (nearly all of us in the development have them and I haven't heard about any problems). Sounds like they cut a few corners? Wouldn't surprise me judging by some of the other (non floor related) problems I've had.

I'm completely flexible on floor height - especially as I'm doing the whole of the ground floor. Would putting a screed in be a huge task? I'm afraid I've no idea what one is!

it doesn't surprise me at all, builders are always saying floating floors are okay to tile onto (that's because they know no different), very few tilers with a decent knowledge of the trade would tile a floater.

putting in a screed would be a fairly straight forward job but it would put your program back a bit. The thinnest screed available to you at a reasonable cost would be a flowing calcium sulphate screed which you could put in at 35mm depth in that scenario. Alternatively you could go for a cement based screed (traditional type) which would need to be 65mm. You could look at things like underfloor heating as well if you wanted. There is a system called the Max4 Therm system which allows a 25mm screed but I am not sure if this is suitable to go on insulation. I can look into it for you if you wanted.

I can give you contacts for either option if you want them.

Hi and welcome..

To determine if you deffo have a floating floor, is there any fixings in the boards at the joints aprrox 400mm apart.?..i,e nails or screws.

The caberboard is 22mm thick so a 35mm screed wouldn't make a huge difference the floor height. I'm not sure about the underfloor heating - I'd love it but it all depends on whether it can sit directly on the insulation (which I presume a screed can?). How much total depth would the screed and underfloor heating add? I just wish (a) the kitchen firm had spotted this earlier (the old tiles were up when they measured up in late August) rather than three days before they're due to start and (b) I'd discovered this forum earlier. I'm tempted to tell the kitchen firm to sort the whole thing out or I'll pull the order (I've paid a large deposit though) - it was avoiding things like this that made me go to them in the first place.

Worst case scenario any suggestions on a ceramic or porcelain opus that would look similar to marble (although sadly it was the texture that drew me to it)? Although I'm guessing you'll say don't tile on the floating floor at all!
