Are you budgeting for a new build or renovation? Understanding the cost differences between hollow concrete blocks and traditional clay bricks can significantly impact your bottom line. Here’s a breakdown of which option offers the best value.
1. Material & Mortar Costs
Bricks (Stretcher bond)
48 bricks/m² at $0.10 + 2 cement bags
Total: $58.40Bricks (Header bond)
65 bricks/m² at $0.10 + 4 cement bags
Total: $92.00Hollow Blocks
11 blocks/m² at $0.67 + 1 cement bag
Total: $68.96
2. Labour Costs
Bricks (Stretcher): $3.00/m² → $24.00 for 8 m²
Bricks (Header): $3.80/m² → $30.40
Hollow Blocks: $1.30/m² → $10.40
3. Total Cost Comparison for 8 m² Wall
Bricks (Stretcher):
Material + Mortar: $58.40
Labour: $24.00
Total: $82.40Bricks (Header):
Material + Mortar: $92.00
Labour: $30.40
Total: $122.40Hollow Blocks:
Material + Mortar: $68.96
Labour: $10.40
Total: $79.36
4. Why Hollow Blocks Are More Efficient
Larger size = fewer units
Less mortar needed
Faster to install, reducing labour cost
Less breakage means reduced waste
5. When Bricks Are Better
Ideal for foundations and load-bearing walls
Higher compressive strength
Better resistance to erosion and moisture
Final Word
If you’re building on a tight budget, hollow blocks offer real savings—in both materials and labour. They’re best for non-load-bearing walls, while bricks or solid blocks should be used where strength is critical. A smart combination ensures you build strong and save more.
