Tiling in our extension one wrong - any ideas??

If I were your tilier I'd be round straight away, otherwise I'd be prolonging the agonny!
Its every tilers worse nightmare to get a call like that.

i was asked to price a job last week on a floating floor....45m2 trav

i refused to quote even when the customer showed me the hallway that had been tiled 5yrs ago and showing no problems.

this is the problem with floating floors, for every floor thats tiled with out any problems theres another 5 that have failed.

very hit and miss and not worth it imo

He is subcontracted through my builder however is due back on Friday essentially to take a look at a couple of the tiles tak them out and see if they can identify problem...However everything I seem to be hearing is that the whole floor is essentially flawed...in particular extension area perhaps because of inconsistent matching of materials.
Someone did suggest potentially adding some sort of corrugated matting over the boards to try to reduce the movement or else to try fixing the boards to make it less 'floating' as it were...

I dont think a decoupling mat will help in this situation as it wont stop the floor moving

mats work with lateral movement between disimilar substrates by isolating the floor from the sub floor but the sub floor needs to be stable for it to work

Ahh right - I am becoming at expert at this now.... It now appears that architects had actually specified a screed floor for the extn area and not sure why th decision was made to not do this.... what about trying to secure the boards in some way using noggins(?) or something else ( not actually sure what noggins are.....) : - ) then relaying the tiles may this help???

 

[mikethetile]

noggins are the pieces of wood that are fixed between joists to stop them flexing

it makes sense that the architect specified a screed floor for a kitchen extension as the prefered floorcovering in a quality kitchen is tiles or stone

removing the floating floor and laying a screed is the best long term solution but its expensive to remove and refit a kitchen

is there any chance of getting the builder back and ask him 2 questions

why did you lay a floating floor when a screed floor was specified

where did you get the spec for the floating floor if the architect didnt specify one

Hi and welcome..

Firstly..IMO Floating floors should be banned full stop..

Back to your floor, was in over boarded in anyway and if so what with and what thickness.?

The floor could be pulled down tighter by screwing and plugging it to the block beam/screed structure underneath.. but again not a guaranteed fix.

The idea of tiling to wooden substrates is for them to be virtually deflection free before tiling commences.

So a few question like mike mentions need to be answered as well..

 

[orchard]

Thanks I think this is what we are looking at - luckily the area of extension has no kitchen units on just our table so this may not be as disruptive as may first seem...

 

[Bathfix Bob]

Sorry for my question but how can a floating floor be identified?

To my knowledge I've yet to come accross one.

basically Bob, it's like a big stud partition wall laid on the concrete slab without any fixings, or just t&g laid onto kingspan type insulation board.
