Enter the screeding work
Calculate from room dimensions or enter the measured floor area directly.
Average thickness matters: floors are not always perfectly level, so the actual screed thickness can vary across the room. The starting 40 mm thickness, 1:4 mix, dry-volume factor and densities are editable planning assumptions, not universal specifications.

It does not automatically include concrete substrate, reinforcement/mesh, fibres, waterproofing, bonding agents, additives, insulation, tiles, floor finishes or labour. Screed type, strength, thickness, joints and curing should follow the project specification.
How the estimate works
Net floor area is multiplied by average screed thickness to obtain wet screed volume. The editable dry-volume factor converts this to an estimated dry ingredient volume. The selected cement:sand ratio divides the volume into cement and sand. Cement volume is converted to mass and whole bags; sand is shown in cubic metres and approximate tonnes. The selected wastage allowance is included in both material quantities.
