From measurements to materials
Net wall area ÷ effective block face area including joints gives the count; the wall volume provides the labour basis.
Put the numbers in context
A 12 m² net wall using a 600 × 200 mm block with 10 mm joints is divided by the effective face module, then rounded up after wastage.
This illustrates the method; your inputs determine your result.Assumptions to check
- The selected block thickness matches the wall thickness.
- Each wall and its openings are measured independently.
- One joint thickness is applied to block length and height.
Limits of this calculation
- Lintels, bond beams, reinforced cells, adhesive coverage and special blocks are not inferred.
Common questions
Will this calculate AAC adhesive too?
Not yet. Use the block count as the basis and follow the adhesive manufacturer’s coverage for the chosen block size.
Why does the final count round up?
Blocks are purchased as whole units, so the allowed count rounds up.
