BAL Waterproofing

[Sanke]

Doing a shower cubicle. Put up hardie backer today & sealed all joints with scrim & rapid set. Tomorrow I was going to apply tanking then possibly install shower tray on legs soliconing in between. Looking at a few vids for tanking they show bringing waterproof mat to top of tray. I was going to take to floor. Which is the right or best way ?

Your shower tray should be fitted first and then Hardie next...

Ideally yes but I am having to match what was there originally

If you run the tanking to the floor then you are defeating the purpose of the tanking as its designed so as if water gets behind the tiles it will run down the tanking & back into your shower tray.

Thanks Stef
i will install & seal tray then bring tanking to tray

Don't forget to overlap the tape onto the tray to provide a watertight seal between wall and tray
