Membrane penetrations

Considering using Schluter wall membrane and the Ditra-Heat mat on the floor.

How anal do you need to be around pipes, cables and screws that penetrate through your waterproofing layer.

I will be fitting the shower shown below with cable and pipe penetrations through the wall. I know there is a 22mm collar that can be fitted for the water pipe. Does this allow you to slide the pipe in and out a bit when you go to connect it up. Similarly what about the electrical cable.
And what about screws that must be fitted to secure the riser rail. Do you seal these when fitting.

With a floor standing toilet bowl there are usually screws either side to secure it on the floor. Obviously you'd have no heating cable placed there but do you worry about screws penetrating the mat.

The @Schlüter-Systems Ltd kerdi pipe seals have a rubber ring so you can move the pipe,.usually the toilet is opposite end of the room from the tray so less chance of water penetration. After drilling the holes fill the hole with some kerdifix then screw down the toilet

The KERDI range has been expanded to include new sizes of pipe collars for pipes from 12 - 140mm in diameter - The range is called KERDI-MV/-PAS and officially launches 1 July.

Any plans to cater for flat electrical cable?
