How We Calculate Brick Requirements
Step 1: Wall Area & Volume
We calculate the wall area (Length × Height) and volume considering the thickness. Current wall: 10' × 10' × 4.5" = 100 sq ft
Wall Area = 10 × 10 = 100 sq ft
Step 2: Brick Count Calculation
Using Standard (9"×4.5"×3") bricks with 0.5" mortar joints. For 4.5" walls, we use single layer.
Brick + Mortar Area = (9 + 0.5) × (4.5 + 0.5) sq inches
Step 3: Mortar Requirements
Mortar volume = Wall volume - Brick volume. Using 1:6 cement:sand ratio for mortar.
- Mortar Volume: 6.98 cubic feet
- Cement: 1 part = 2 bags (50kg each)
- Sand: 6 parts = 8 cubic feet
Key Assumptions
- • Standard brick: 9" × 4.5" × 3"
- • Modular brick: 7.5" × 3.5" × 2.5"
- • 9" wall uses double layer of bricks
- • Mortar ratio: 1:6 (cement:sand)
- • Dry volume factor: 1.33 for mortar
- • Cement density: 1440 kg/m³
Pro Tips
Brick Selection:
- • Standard bricks for load-bearing walls
- • Modular bricks for lightweight construction
- • Check local brick availability and sizes
- • Consider brick quality and water absorption
Construction Tips:
- • Maintain consistent mortar thickness
- • Soak bricks before laying
- • Check wall alignment regularly
- • Allow proper curing time
