Liquid membrane over formed tray

[Impey Showers]

We'd love to see the final wetroom. :>

personally I have been fitting Impey trays for years, mainly for vinyl floors for councils but I have also done some tiled wetrooms with the Impey tanking kits and trays and I can highly recommend them. Doing a tiled wetroom at the moment using this kit, I will put some pics up soon

Do share your photos of before, during & after. It will be interesting to see what your interpretation of 'tanking' is with the @Impey Showers waterguard membrane....... whether you only lap the joint tape up the wall 75mm and claim to the customer that it is now fully waterproof or whether you do what must of us conscientious tilers do and fully waterproof the wet area? An interesting debate had recently with Impey!!!

I sort out many failed wetrooms. I'd say 9/10 are Impey poorly installed with inadequate (if any) waterproofing. The other 1/10 is Wedi - easily available for installation by the inept.

I've yet to come across a failed Schluter tray, but that's probably as they are STILL hard to purchase!

Most Wetroom/shower tray failures happen where the grout cracks, usually corners, so I always make sure that tanking covers the complete shower area including up the walls.

But corners and perimeter joints should be siliconed, not grouted

the tanking kit comes with a semi curing silicone which I apply to all the joins before any tiling is done, horrible stuff. I do grout my corners, then clear silicone over once dry

That's still not right your corner joint should be clear of grout and adhesive then it should be siliconed to allow for movement

Agreed ^^

What tanking are you using?

Most failures I see are due to water sitting beneath the tiles and degrading the (usually spot-fixed) adhesive. That, and silicone around the drain which prevents sub-surface drainage.
Not a problem which is even possible with Schluter drains.
