Another suspended floor topic

[SiBee]

Hi members,

couldn’t find my answer in previous topics so asking for some pro guidance.

Bathroom refurb due to a flood. 
I’ve taken a big camber out of the floor so all boards now can sit flat but the area is not level. The bubble is just touching on the line. I don’t want to remove anymore from the timber beams so what’s the best way to achieve a suitable level?

we have a low profile 1800 x 900 stone tray to go in which is flat underneath and the rest of the rm will be tiled with loose lay wire heating bedded into the tile adhesive for comfort and not rm heating.

 

Should I use self level compound for the whole area and then continue or, level the tray in the adhesive of choice something like ct power grab and then tackle the remaining floor area  I.e take out imperfections with adhesive > 6mm insulation boards> decoupling layer > tile adhesive with heating wire > floor tile.

Tray manufacturer recommends a smooth flat surface to bed down on with a suitable silicone adhesive. The tray is very heavy so don’t want to be relifting once in place😀

Input appreciated as always

ps could only upload two pics, size is inside allowance?

Ah mate, compared to some new builds with heavy furniture on the chipboard and joists, that's perfect!

 

You're building a house, not a rocket ship.... As long as the bubble is between the two lines, focus your energy elsewhere.

 

 

FWIW took us 2 years to realise our cemfloor corridor floor was on the piss, after wife used a tripod laser level to measure a line for a 50% up the wall painting job. Each doorway varied by a cm or two due to the cemfloor seemingly not being level.
