What the best way to...

Create fall on a concrete floor towards a shower former? Former wil be chased in and finished floor surface will be the vinyl wet room flooring. Its to be used for disabled access. Have done plenty of wet rooms all have been installed on timber floors so concrete Is new to me. Don't want water to pool anywhere. Thanks ollie.

Is just falling in one direction or is it falling in several directions towards a centre drain?

The shower former will be installed in the corner of the room so there needs to be slight fall towards the former i don't want the water to pool anywhere and was worried if there wasn't any fall to the former that would happen.

You would be best to use a semi dry screed rather than a concrete (subtle difference is simply that the concrete has gravel in it)

if you are really unsure I could put you in touch of some good screed installers...

however, you could set up a shutter system (screed rails) to guide the screed level. Then simply fill the former with screed, compact it and scrape it off to the tops of the screed rails. Remove the screed rails whilst the screed is still plastic and carefully infill the gaps that are left. Alternatively you can buy formers which can be left in place.

All you need is falls from either walls to fall to wards the former to prevent pooling.. this can be done with latex slc mixed slightly thicker than standard , the slc must be capable of finishing to feather edge.. once set, finish ridges with a smoothing stone... on timber floors you can ply the outer edges and then latex slc back to former at feather edge.

I work on one of these Altro type wetrooms every week all yr round..and have seen the floor layer use many trade tricks to get floors to fall in loads of directions with latex slc.
