Opening your workspace…
Enter the block size and wall thickness, then deduct the openings. The result rounds the net wall up to whole blocks.
Follow the method, check the example and review the assumptions.
Net wall area ÷ effective block face area including joints gives the count; the wall volume provides the labour basis.
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.Not yet. Use the block count as the basis and follow the adhesive manufacturer’s coverage for the chosen block size.
Blocks are purchased as whole units, so the allowed count rounds up.
