What are large, two-hole clay bricks? How do they differ from small, three-hole bricks?
Large 2-hole brick It is a clay brick of a certain size. 5 × 6 × 15 cm. Designed to be a “balance” between construction speed and cost-effectiveness, larger than smaller 2-hole bricks, allowing for faster wall construction, using approximately 25% fewer bricks, and also preserving… 2 holes This allows the mortar to penetrate and form a strong mechanical bond, which is an advantage that solid bricks lack.
Compared to large, three-hole bricks, this model is smaller, lighter, more cost-effective, and significantly shortens construction time. It's ideal for projects requiring a balance between cost, speed, and strength.

Key features: Large, two-hole clay bricks (AY Contento)
Faster construction than smaller blocks (~25%) — saves on labor costs.
Using only 95-100 bricks per square meter, compared to 120-130 smaller bricks, significantly reduces construction time and labor costs without the high price of 3-hole bricks.
Better adhesion to mortar than solid brick — Mechanical Bond
The two holes allow mortar to penetrate and lock the bricks in place, creating a stronger mechanical interlock that is superior to a smooth surface. This results in a durable wall that will not peel or flake in the long run.
Better value than 3-hole models — optimal balance.
The price per block is lower than larger 3-hole bricks, while still offering significantly better construction performance than smaller bricks. It's ideal for projects requiring maximum ROI.
Perfect weight for a craftsman's hand — durable and easy to build.
Weighing 0.55 kg per piece, it's easy to grip for all-day construction work. It's three times lighter than large 3-hole bricks, reducing fatigue for workers during continuous construction projects.

Applications
- Interior partition walls in residential buildings that need to be constructed quickly while staying within budget.
- Typical exterior walls of buildings that require strength and good mortar adhesion.
- The job requires faster processing than smaller projects, but the budget isn't enough for three-hole bricks.
- Fence and wall construction projects that require both speed and durability.
- Commercial buildings and warehouses that require a balance between cost and efficiency.
Transportation
| Vehicle type | Quantity (approximate) | Suitable for |
|---|---|---|
| 6 wheel truck | ~18,000–20,000 pieces | Small-to-medium scale construction projects |
| 10 wheel truck | ~30,000–35,000 pieces | Medium-sized projects |
| 18-wheeler truck (trailer) | ~50,000+ pieces | Large-scale projects |
FAQ
Large blocks (5x6x15 cm) require 95-100 blocks per square meter. They are approximately 25% faster to lay than smaller blocks, reducing labor costs and construction time. Suitable for moderate-sized projects requiring time management. Small blocks are slightly cheaper, ideal for very limited budgets or minor repairs.
2-hole large blocks are smaller (5x6x15), lighter (~0.55 vs ~1.6 kg), and cheaper, but slower to build (95-100 vs 40-45 blocks/sq.m) and don't have a large air gap like 3-hole blocks. If you want very fast construction and a cool house, choose 3-hole large blocks. If you want a balance between cost and speed, choose this option.
For a 6 cm thick wall, approximately 95-100 bricks per square meter are needed, including a ~1.5 cm mortar joint. It is recommended to order extra. (5-7%) Use our brick calculator.
Yes, that's right. Clay bricks are stronger than lightweight blocks. You can drill into them with a rotary drill and use regular plugs; no special plugs are needed.
