Wetroom with UFH - preparation and tanking

[AliGage]

I got confused on a post recently where Ash (Mr TeaBag) asked some questions over tanking with a spread on gum waterproofing.

I'm in the middle of a wetroom install at the moment so thought I'd share my pictures.

This job was originally prep'd by someone else, consequently very poorly. So, SLC, UFH, durabase, puddles of adhesive, offcuts of OSB, and rotten floorboards were all removed to reveal rotten joists.

Joists were repaired, support for new wet tray created, some plumbing altered and 18mm WBP marine ply screwed to new timbers.

Marmox boards installed. Glued and screwed with washers.
UFH cable and probe installed.

I used some off cuts of marmox boards to make a "flood barrier" for the SLC. Once set they are removed and the wet tray gets covered and shaped for falls.

Then it was on to the tanking. For this install I used BALs WP1 and Orby jointing tape and corner profiles.

Once dry we can start our tiling!

Nice to see a small rubi. Thought I was the only one who has the star cutter.

 

[AliGage]

Always a handy, compact cutter for little ceramic jobs.

Ali, when you say "tray gets covered and shaped for falls" , have you made your own falling tray in there? Or have you added some form of screed/addy in there following the falls in order to bring the edges upto rest of floor height?

 

[AliGage]

The later mate. But the floor was quite out of level as it ran toward the door. So in an attempt to bring it right the wet area became quite deep. Yep there is a marmox former in the bottom. But when covering the cables the nearside was built up 20mm where as the back corner was less than half that.

I used a thicker mix of fibre reinforced SLC and effectively rendered the wet area following the falls in the former. If that makes sense?

 

[STEVO]

yep, gotcha. thought thats what you were getting at.
