Onoff Posted June 12, 2018 Author Share Posted June 12, 2018 The Geberit wall drain... Falls are good but I'd like to make good a shallow "channel" where the angle former sat. Maybe 2mm deep. The blue membrane folds out and gets stuck down to the concrete. It's worked out good tbh. Would a smear of tile adhesive suffice? Link to comment Share on other sites More sharing options...
bassanclan Posted June 12, 2018 Share Posted June 12, 2018 Have you got any SLC handy? Otherwise tile adhesive will do for 2mm Link to comment Share on other sites More sharing options...

Does the concrete channel need priming with anything before the tile adhesive gets smeared in? Link to comment Share on other sites More sharing options...

Onoff Posted June 12, 2018 Author Share Posted June 12, 2018 I half considered running a couple of lines of Fischer FIS V 360S resin down the channel and levelling off. Link to comment Share on other sites More sharing options...

Nickfromwales Posted June 12, 2018 Share Posted June 12, 2018 Iirc the video shows tile adhesive being used to set the membrane ? Dampen the slab with a wet sponge first. Link to comment Share on other sites More sharing options...

Dampen the slab with a wet sponge first. So I'm at about the 3m 50s stage in the video. Feels to me that whatever they're trowelling on is more of a sticky, plaster like "creamy" product than the Mapei tile adhesive I've just used?

When I used the tile adhesive to fill the Aqua Panel joints I just poured some water in a bucket and mixed by hand with a trowel. Seemed to go OK. Would "whisking" it with the paddle mixer make it go "creamier"? Link to comment Share on other sites More sharing options...

Trapping air in any cement based product that you want to be strong is not a good idea. As @Nickfromwales said - wet the concrete with a sponge and then slap the adhesive on.... 1 Link to comment Share on other sites More sharing options...
Onoff Posted June 13, 2018 Author Share Posted June 13, 2018 That seemed to work and goes on the same colour as in the Geberit video! Seemed "smeary" enough too. Holding the membrane up with a bit of duct tape to keep it out of the way. Maybe a mm over but I can live with that. So in theory, once dry, the membrane folds out and gets similarly "smeared" over/on. Link to comment Share on other sites More sharing options...

Onoff Posted June 14, 2018 Author Share Posted June 14, 2018 (edited) The Geberit wall drain, it's one thing watching the CGI video! So the membrane is sort of rolled up tight. It's Sellotaped which you remove: It appears completely waterproof: Guessing I need to make damn sure there's no sharp edges here: I'll have to watch the video again! Seems the tile (mosaic shown as example) sits like this: There's a bit of very thin st/st sits between the membrane and tile at the threshold to the drain: I've also ordered the st/st front plate to cover/finish it at just over £70!

PeterW Posted June 14, 2018 Share Posted June 14, 2018 Once it’s bonded between layers of adhesive and tile it’s going nowhere ..! Looks like the same stuff they make the plaster-in frame sealing membrane from. 1 Link to comment Share on other sites More sharing options...

Onoff Posted July 14, 2018 Author Share Posted July 14, 2018 I'd clean forgotten about the floor / back of the laundry cupboard. SWMBO wants to put the dirty lien basket in here. Plan ORIGINALLY was to bring the back wall of the cupboard forward hence not caring about the rough, high slab edge. In the cold light of day I felt I needed to level it off with the rest of the floor. The old incoming mains water can be cut off now at/below floor level and that new copper used to down feed the cistern (pipe poking out from the right. DPM coming up in blue, I cut that off 2" above the corrugated / EPS slab perimeter strip.: And then hacked off the raised edge: Figure I'll fill that void with some concrete, level off and tile all the way in. I can figure the back of the wall / boxing in later. Link to comment Share on other sites More sharing options...
