Compound walls around factories, godowns and plots are one of the most common jobs in Tiruppur. They are long, exposed to weather and need to go up quickly — which is why solid concrete blocks have become the usual choice.
Blocks or bricks?
| 6" solid blocks | 9" fly ash brick wall | |
|---|---|---|
| Speed of laying | Fast — large units | Slower — many more units |
| Mortar | Less per m² | More per m² |
| Strength | High — suits long walls | Good |
| Units per m² | ≈ 12 blocks | ≈ 98 bricks |
| Best for | Factories, godowns, plots | Homes wanting a brick finish |
Quantity per running metre (6" blocks, 15" × 8")
| Wall height | Area per running metre | Blocks per running metre |
|---|---|---|
| 5 ft (1.5 m) | 1.5 m² | ≈ 18 |
| 6 ft (1.8 m) | 1.8 m² | ≈ 22 |
| 7 ft (2.1 m) | 2.1 m² | ≈ 25 |
Based on about 12 blocks per m² with a 10 mm joint. Add 5% for breakage, and deduct gate openings.
Worked example
A 60 m factory boundary, 6 ft high: 60 × 22 = 1,320 blocks. Add 5% → about 1,390 blocks.
Good practice for long compound walls
- Provide piers or columns at regular intervals as your engineer specifies.
- Use a plinth beam or proper foundation along the full length.
- Leave expansion gaps in very long walls.
- Cure the mortar joints for several days.
