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?

Have you got any SLC handy?

Otherwise tile adhesive will do for 2mm

Ta. No, no slc here. Does the concrete channel need priming with anything before the tile adhesive gets smeared in?

This bit, my exotic SBR, pea shingle mix was laid April 1 2018. That's yesterday in my book!

I half considered running a couple of lines of Fischer FIS V 360S resin down the channel and levelling off.

Iirc the video shows tile adhesive being used to set the membrane ?

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?

I think it's just a very small trowel size to be able to smooth it so tightly

Ta. 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"?

No and you don't want it to as with a cement based adhesive, the creaminess is from water, cement and air mixing. 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....

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.

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!

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.

B0LL0CKS! :(

 

At around 4.45 in the video there's a stainless steel strip that goes over the drain threshold.

 

I can't find it!

 

I can't see that I've "boarded it in" the walls but...

Let me know if you can’t find it and I’ll see if it’s available as a spare ..

Cheers. Could be a lifesaver! :) Going to have a bloody good look first. Always the option to drill a hole (s) for the snake scope and have a look behind the mitre section.
