Bathroom Floor Screed Fall

This will form the wet room gradient.

Bathroom floor screed fall.

It s important to get each section flat you can do this by transferring screed from one section to another. It is also possible to remove the screed within the shower area to allow the drainage outlet to be fitted selflevelling latex to be poured and a floor former installed on top. This is more likely to happen if the screed is too thin. It is particularly important for bathrooms as an incorrectly levelled floor will cause water runoff to pool on the floor rather than run into the installed drainage point.

Then using a flat trowel spread the screed across the entire shower base to cover the glue and wedges. Bathrooms need fall as any water issues there won t go on to flooding the rest of the house. Cutting and grinding slab wouldn t be such a problem if it was a ground floor but upstairs you will be weakening the slab and if the reinforcing mesh has been put in correctly then very close to exposing that. Bonded screeds should therefore be thin normally less than 50mm.

Scrape the screed back to the level of the wedges with a flat piece of wood. An unbonded screed is separated from the slab or substrate below and the main way that an unbonded screed fails is to lift or curl. This is more likely to happen if the screed is too thick. For bathroom floors the recommended minimum fall to the waste shall be 1 100 10mm per 1m.

Wet room solid floor gradients. Water sits for over 24 hrs or longer until it eventually evaporates. Not many people realise that before you tile a floor it is important to lay a bed of screed to ensure your finished floor is levelled correctly. For shower areas with a vertical separation between the shower area and the wet area such as a shower screen hob set down or water stop the fall to the waste shall be 1 100.

During our recent 6 month post completion maintenance inspection the builder stated that as the shower was not leaking they would not fix the fall or drain. The fall to the drain appears minimal and the shower drain itself sits slightly proud of the floor. So this is how i make my floor screed a 4 to 1 mix with little water mixing the floor screed slow and not over mixing the sand and cement will keep it at a.
