Waterproofing cuts and corners on aquapanel?

[curium]

Hi

I'm doing an ensuite shower. I have fixed Wickens aquapanel to the walls where the shower cubicle will be.

I am concerned about openings in the aquapanel for the shower pipes and the corners where the aquapanel boards meet.

There will be some mosaic tiles and a power shower so I'm wondering if I should use some form of tanking product in these vulnerable areas.

Can anybody recommend how to proceed?

I'm planning to use BAL Single Part Flexible adhesive and a BAL grout if that is relevant.

Knauf recommend just taping where the board meets but that strikes me as only dealing with strength rather than water-resistance.

Would be interested in how others have dealt with this.

Cheers!

EDIT:- The shower-tray will have upstands so I'm only really concerned with the gap where the boards meet and where cuts have been made in the board for services.

I have a wet room and where the pipes came through I just sealed with good quality sealent before tiling. The one I used was a product called CT-1....amazing stuff and sets under water if need be.
