Typical Scenarios in UAE & Gulf Projects
A villa project requires 120m of boundary wall at 2.4m height using 400×200×200mm hollow blocks. The calculator estimates 3,600 blocks (12.5 blocks/m²), 4.3m³ mortar, 86 bags cement, and 8.6m³ sand with 5% wastage allowance for cutting and breakage.
An Abu Dhabi office fit-out needs 850m² of partition walls using 400×200×100mm solid blocks. Calculator determines 10,625 blocks, 3.8m³ mortar for the thinner joints, accounting for 15% openings for doors and service penetrations.
