Large floors

[DemoXpert]

Question for the pros- how large a floor b4 having to add expansion joints?

Maximum bay size of 10m in each direction I believe is British standards.
I've always gone for 8m.

Take it there's none in the substrate? What's the room size? Any UFH? And what are you fixing?

 

[DemoXpert]

Fixing porcelain, no UFH, not certain on the exact size of the room... Will get the size soon. No expansion joints on the substrate. Thanks for your reply AliGage

Doesn't (from the photo) look big enough to worry about expansion joints. Just use ditra.

 

[DemoXpert]

Think you read my mind, as I was about to ask about ditra- under what circumstances would you decide to use it? This being an up and coming bathroom showroom, I don't think the guy will want to part with the dosh, as ditra is not cheap!... Besides I saw the previous showroom and there was no ditra whatsoever, but I could surely suggest! As an uncoupling solution in this case?

 

[AliGage]

Ahhh , so potentially there will be display areas if suites with different flooring?

 

[DemoXpert]

Yup most certainly will!!!

 

[AliGage]

Wouldnt worry too much about expansion joints then. Id presume bays for displays will be set out and tiled independently.
Use chrome threshold "T" bars to finish the display bay tiles with the main walkway flooring. These, effectively will be suitable expansion allowance.

Makes a lot of sense! Thank you very much for the advice!
