Bathroom Floor Screed Fall

This is more likely to happen if the screed is too thin.

Bathroom floor screed fall.

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. This is more likely to happen if the screed is too thick. Then using a flat trowel spread the screed across the entire shower base to cover the glue and wedges. 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.

The fall to the drain appears minimal and the shower drain itself sits slightly proud of the floor. 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. 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. For bathroom floors the recommended minimum fall to the waste shall be 1 100 10mm per 1m.

Bonded screeds should therefore be thin normally less than 50mm. 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. Scrape the screed back to the level of the wedges with a flat piece of wood. Wet room solid floor gradients.

Bathrooms need fall as any water issues there won t go on to flooding the rest of the house. It s important to get each section flat you can do this by transferring screed from one section to another. 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.

This will form the wet room gradient. This will create the natural run off for the shower base. 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.
