Easiest way to maintain fall with Impey tray ?

[AllurePTS]

Just about to embark on my first proper wetroom and I'm a bit concerned about how to maintain the fall and angle on the Impey tray :20:

Tray is fitted and floor ply'ed out level with the tray .....it's going to get fully tanked with Impey tilesafe then devimat on top (including the tray former) then to be levelled over with cempolatex slc.

1) should I level the floor out with the slc but keep it out of the tray former area ???

2) Tile the tray former first then go across the rest of the floor ???

3) how do I keep the fall and angles right for the tray .....it's so slight that I imagine I'll lose it with the tilesafe and devimat ???

Any advice please guys

I've not used the Impey tray yet, but if it's anything like the Tilux the fall won't get lost with the tanking products. If they are fitted correctly then I would imagine you'll end up with the same fall as you have when the tray is fitted.

As for tiling. I did the tray first then the rest of the floor.

If you do use slc on the floor, bear in mind that the tray will need to be level with the floor after the SLC has been applied. I don't know about the Devimat but with the Tilux and the concrete screed arrangement I had I was able to build up with a bit more SPF to get the tile to run from the screed onto the former where the former was lower than intended.

We wouldnt recomend the use of UFH over the tray and you should be thinking of a stress membrane over the ply to prevent cracks. Tilesafe isnt your ideal membrane for the wood floor as it is just a tanking membrane, it does high build around the base and wall floor transitions which can be a pain.

Well, I would rather not be doing it this way either ....however - Impey say that Tilesafe is "ideally suited for floors, must be used on the aqua dec, devimat is recommended and is perfectly safe for use in the shower" ..... the customer knows all this and has bought all the gear, so I have no choice but to go about it this way :smash: ..... I've used The Tilesafe before, so I know what the difficulties are - that's why I'm worried about how to maintain the fall and angles properly and getting it all at the correct build up with slc whilst excluding the aqua dec :83:..... what I need to know is - what are the best /easiest ways of going about it with the Impey stuff ???

cheers

Cheers Cornish ....I know the fall won't be "Lost" with the tanking ...I'm just thinking it will be hard to find and follow with the devimat on top of it too ??? :smash: .....The height issue is what I'm thinking about as well .... I'm also wondering how the hell I'm gonna block out the aqua dec (with the devimat on it) so I can do the slc on the rest of the floor !!!:83:

I'm really not looking forward to this one !!!

Can UFH mats be used on Tilesafe membrane? Alarm bells ringing here, check with the helpline.
As for the fall, use a marker pen to draw the fall on the tray and on the wall so you know where it is when you lay down the tile safe. Dry lay the tiles and continue the fall line through the tile (not with your marker pen!) Use your wet cutter and the cut should provide you grout line gap.

Yes but they recomend 100w devi mat.

There are cases on here of Impey installs with tilesafe and devi..........you have a drainage prob and have used ufh you WILL lose the whole room.

Falls.......honestly there is no trick or best way experience and ability figure here go slow and judge as you go m8

What wall & floor tiles are you using and what size m8 ?

Well mate, I guess if he loses the whole room, he's gonna have to speak to Impey about it .....The Customer "knows best" ....guess I'm happy enough with going about it in theory anyway ! .....just nervous about the fall being so slight and like you say ....tilesafe and devimat on the dec :83:

Anybody suggest how I block out the aquadec for the slc when it has tilesafe and devimat on it ??? :83:

Walls are Ceramic Mosaic ...floor is ceramic 300x300 (I know ...I've had the conversation at least a dozen times about this too !) :83:

Tilesafe is the only waterproof membrane specified for wet areas that can be installed by specialists who offer a 10 year insurance-backed guarantee; they also recommend the area is fully flood tested prior to the installation of tiles, can this be done with other products!?

Tilesafe is also specified and installed by some of the largest architects and main contractors in the UK, so they can’t all be wrong.

Oh and also, the Tilesafe does work as an uncoupling membrane… just for your info. wetdec

I'll ask out of couriosity, but do you in some way represent the manufacturer of Tilesafe?

If you do, it's important to put your hand up to it, so that we can understand that someone with a commercial interest is commenting. If not then I would be interested to know how you would back your statement up.

Well, if I don't ask, I'm sure that one of the moderators will.

AllurePTS -

Yes only slc outside of dec area if necessary.

Tile former first then rest of the floor, starting from the gully/grate outwards.

The Tilesafe and Devimat are only 2mm thick so as long as you keep your tile adhesive the same approx. thickness throughout you will not lose your falls.

Cornish - No i don't in any way represent the manufacturer. I work for a wetroom installation compan who have tried and tested nearly all the pre-formed decs & membranes available & we have found the Tilesafe Membrane to be the most effective and failsafe way to waterproof a wetroom. (I'm just knowledgeable )

Not sure I understand this...Tilesafe is 2mm thick and the devi mat cable not including the mat is ~6mm so where do you get 2mm thick from.

This is good to know.........How do you manage to get around the weight restriction put on the Tilesafe by manufacturers when using tile safe on walls, is there a way around the sagging then as Impey themselves are shying away from this area now ??

Tilesafe will acommodate a little movement say to cracking too 2mm but is not an uncoupling membrane, its a tanking membrane and should be treated as such

Welcome...go say hi in the new members forum

Wetdec....

I will go and say hi in the new members bit...should have done that first.

About Tilesafe and Devi, should of made myself clearer, i was more specifically talking about the Tilesafe being 2mm, you're right mate.

We use Mapegum WPS on the walls in conjunction with Tilesafe on the floor (with 75mm wall upstand and all corners done in reinforcing tape and WPS painted on over the top of upstands etc) when the tiles exceed the weight limit - 20kg per sqm (including tile, adhesive & grout) or generally advised as no thicker than 10mm tile including adhesive. WPS is good because it has been tested with Tilesafe and is fully compatible - easiest way we find.

Thanks for the offer Wetdec, will pop you an email shortly
