Concrete floor-ufh-porcelain tiles

[dziqs]

Hi
In my bathroom I have a concrete floor, on the top of it is coming ufh (uniprom/unipipe) and porcelain tiles. Question is what should be used betwen ufh and porcelain tiles?? only flexible adhesive or maybe some leveling compound and than adhesive?

How thick are the pipes on top of the screed floor

 

[dziqs]

I think around 10mm. why? for what do you need it?

Not one I've come across on top of the screed, 10mm,s quite a thickness

 

[dziqs]

? what do you mean

 

[nybor62]

surely it should be laid on top of insulation boards first then screed over

I would sugest to use UFH electic 1 if it's only in the bathroom, you floor will come really high if you fit uniprom pipes

Hi dziqs.

I see you intend to lay underfloor water heating pipes on top of concrete? I think that such pipes should normally be laid as part of a new screed floor, with a floating insulation layer, then pipes and screed covering the pipes. Then tile on top.

If you are not replacing the floor electric ufh is the best solution, it still needs to be laid on an insulation layer (usually 6mm boards e.g. Marmox boards) then best course is to cover the cables with self levelling compound, then tiles on top.

Have you had anyone with prior experience of ufh come and assess your needs? I strongly recommend that you do so before you part with any cash and definitely before anything is laid and set in concrete or adhesive!

the thing is that I have that ufh in whole flat (1 bed) in the hallway and lounge is intalled laminate flooring but in bathrooms will go porcelain tiles.Builder who didn't finish the job fixed a thin plywood on the top of ufh but it doesn't make a sense does it?

Thin ply on ufh don't sound right, how thick was the ply

 

[dziqs]

I think 9mm

so they put the heating down then ply over the top is that all
