Creating a fall in floor tiling

[jimmi-c]

Ive been asked to tile a large floor with a drainage gully at one end. The screed is realitivly flat. Am i right in thinking that the screed should form the fall and i just tile to that? Rather than trying to build up with adhesive.

Also another floor upstairs is plywood with a gully in the middle and this has to be tiled so water runs into the gully . How can this be done?

Any help much appreciated

Thanks

When you say large, how big is it?

When you say large, how big is it?

The screed floor is about 25m2 and the plywood one is about 15m2

What are the areas used for kitchen etc...

Is this in a commercial environment? I can't remember of the top of my head the correct fall ratio but to drain the water quick enough you could be looking at a drop of up to 100mm over a 5 metre run

They are toilets/changing rooms.

To achieve That sort of gradient i assume the screed would have to be sloping down towards the gully?

What about the ply wood floor? Some sort of pre-formed tray perhaps?

If you have to ask how - you shouldn't be doing it!
This type of work isn't DIY and you will not pick up the experience from a forum.
