Level On Top Of Water Proof - TilersForums.com

[james hailwood]

Hello, just got to a wet room job and the tray Is fitted and water proofed but the floor is way out at the entrance of the room. 17mm out. They're having 60x60 rec porc. My issue is whether I can Chuck some self leveller on to of the waterproof to build the floor up. But this would make the falls in to the tray even steeper as it has to meet flush with the drain. The builder says the customer is a pretentious nightmare lol

Who installed the former? This should have been addressed at time of installation not now when ready to tile.

Builders installed it, this is my first job for him.

To answer your question, yes you can level over tanking.

Your can, however 17mm worth of SLC at the edge of the former will act like a sponge for water

So the builder knows there picky and still didn't bother to check the floor for level in a wetroom what a twit I'm my experience if the first job for a builder is a scre up they all will be lol I've bin there and got the T shirt lol

You either stick to tiles on and get paid or turn it down.

common problem.they dont give a s... about the tiler.call him back and fix it. if there is floor heating in the outer area,you can gain back 6-7 mm.i had this problem before,now i build the tray myself.

You could self level it round to the edge of the tray & try & feather it just onto the tray & then tank the floor again with Mapei Aquadefence.
