Concrete blocks vs bricks: which costs less per wall?
Concrete blocks or clay bricks for your walls in Pakistan? Compare cost per square foot of wall, speed, strength, weight, insulation and quality checks.
Published 4 min read
The short answer
Concrete blocks and clay bricks can both build good walls. Blocks are larger, so a wall needs fewer units and less mortar and goes up faster; bricks are traditional, widely available in Punjab and easy to work with. The only fair comparison is the cost per square foot of finished wall — units, mortar, plaster and labour — for the same wall thickness, using well-made materials from reliable suppliers.
Key takeaways
- Compare cost per square foot of finished wall, not the price per block or per brick.
- A wall needs about one 8×16-inch block per square foot, versus about 4.5 bricks for a half-brick wall.
- Blocks lay faster and use less mortar; bricks are easier to cut and fix into.
- Block quality varies widely — check curing, edges and size.
- Follow your engineer on wall type and thickness, especially for load-bearing walls.

The basic difference
| Clay bricks | Concrete blocks | |
|---|---|---|
| Size | About 9 × 4.5 × 3 inches | Often 16 × 8 inches on the face, 4 to 8 inches thick |
| Units per sq ft of wall | About 4.5 (half-brick wall), 9 (one-brick wall) | About 1 (16 × 8 face) |
| Weight | Heavy per wall area | Hollow blocks are lighter per wall area |
| Mortar | More joints, more mortar | Fewer joints, less mortar |
| Speed | Slower | Faster to lay |
| Where common | Punjab, KP and most of the north | Karachi and parts of Sindh; growing elsewhere |
Compare the cost of a finished wall
A block costs more than a brick, but you need far fewer. The fair comparison is the cost of one square foot of finished wall:
- Units: bricks or blocks per sq ft, plus breakage.
- Mortar: cement and sand for the joints.
- Plaster: uneven brick walls often need thicker plaster than true, even blocks.
- Labour: blocks are usually quicker to lay per square foot.
Ask your contractor or supplier to price a square foot of each wall type at the same thickness, then check the material rates. See brick rates and cement rates.
Strength and safety
Both can be strong when well made and properly laid. In most modern houses, the RCC frame — columns, beams and slabs — carries the load, and walls fill between them. Where walls are load-bearing, the engineer’s design decides the material and thickness. In earthquake-prone areas, how walls are tied to the frame matters as much as what they’re made of. Don’t switch materials without your engineer’s approval.
Quality checks for blocks
Block quality varies more than brick quality, because blocks are made in many small yards:
- Curing: well-cured blocks are hard; poorly cured ones crumble at the edges and corners.
- Size: blocks should be uniform; uneven blocks waste mortar and plaster.
- Tap test: a clear sound is good; a dull, powdery one suggests a weak mix.
- Drop test: a good block dropped from a low height onto soft ground shouldn’t break.
- Ask for test results from larger manufacturers for load-bearing work.

Heat and comfort
Clay bricks have good thermal mass: thick brick walls soak up heat in the day and release it slowly. Hollow blocks trap air in their cores, which slows heat flow. In practice, wall thickness, plaster, roof insulation and shading matter more than the choice between the two. Lightweight AAC (autoclaved aerated concrete) blocks, available from a few manufacturers, insulate better but cost more per unit and need suitable mortar or adhesive.
Practical points
- Fixing heavy items: hollow blocks need suitable anchors for cabinets and water heaters.
- Cutting: bricks are easier to cut for services; blocks may need a grinder.
- Wiring and plumbing: chase with care in hollow blocks to avoid breaking through.
- Availability: use what local suppliers make well — a good local brick beats a poor block, and vice versa.
Checking prices fairly
In DAAM, block prices are tied to size, type (solid or hollow) and city; brick prices to class, the per-1,000 unit and city. Ask for both in your city, then work out the cost per square foot of wall. See our city guides for Karachi and Lahore.
Frequently asked questions
Are concrete blocks cheaper than bricks?
Per unit, no — but a wall needs far fewer blocks and less mortar. Compare the cost per square foot of finished wall, including plaster and labour, for the same thickness.
How many blocks are needed per square foot?
About one block per square foot of wall for a standard 16 × 8-inch block face, plus a little for breakage. Clay bricks need about 4.5 per square foot for a half-brick wall.
Are block walls strong enough for houses?
Well-made, properly cured blocks laid correctly can build strong walls. In most houses the RCC frame carries the load; follow your engineer’s design for any load-bearing walls.
What are AAC blocks?
Autoclaved aerated concrete blocks are lightweight and insulate well. They cost more per unit and need suitable mortar or adhesive, and are available from a few manufacturers in Pakistan.
