Floor Screeding, quantities & volumes calculator.
Enter your dimensions in the panel
provided to calculate the estimated quantities required for your floor
screed. (some assumptions have had to be made to keep
this form simple).
for info on the differing types of floor screeds.
The calculations will be completed when you leave the last input field.
This can only ever be a rough approximation due to differing geographical material and labour costs.
Screed prices for this calculator are averaged out between 25mm and 75mm thicknesses, which will give a slight bias either side of the mean price.
Ready-Mixed sand & cement
are an in-situ flooring of cement mortar laid to an accurate flat surface by screeding,
or by self-levelling. Common types are -
floor screeds are an ideal screed for flooring applications.
It can be used as ground floor slabs (floating foundations),
used on suspended floors, as a topping to lightweight screeds
based on perlite or other lightweight aggregates and can also be
used as a floating construction over insulation to give acoustic
or thermal properties.
Retarded in order to remain workable for 8-12 hours
Consistent quality is guaranteed
Better cement dispersion gives greater and more uniform compressive
strength throughout the floor area.
Pre-mixed provides consistent quality materials and accurate
have been developed to meet the increasing demand for factory-mixed sand & cement screeds incorporating an even dispersal of polypropylene fibres. Suitable fibres introduced in the mix can provide cohesion and help control cracking caused by stress.
Self levelling screeds
Minimum early shrinkage or cracking
Improved strength and flexural fatigue resistance
Can eliminate the use for wire mesh
Easy to place, compact and overcomes many practical problems when used as an
alternative to steel crack controls
Better impact and abrasion resistance
based on alpha hemihydrate calcium sulphate are ready to use and have advantages over
semi-dry floor screeds, however they are not for the DIY market. They are less labour
intensive and up to ten times the area can be laid with one gang compared with traditional
semi-dry screeds. Also
shrinkage and curling is very unlikely to occur. They can also be laid
thinner than conventional semi-dry floor screeds.
May be lightly trafficked after 1 to 2 days, depending on drying conditions.
Care should be taken to avoid excessive water loss in the first 24 hours.
If windows or external doors are not installed, temporary
provision must be made with polythene or similar. Direct sun
must also be avoided during early life.
Abrasion & impact resistance are good when compared with
traditional sand & cement floor screeds. However, screeds
should not be treated as wearing surfaces and care should be
taken to protect against excessive impact.
