The construction industry in Bangladesh is evolving rapidly. With growing urbanization and large
infrastructure projects, the demand for high-quality, environmentally friendly bricks has
increased significantly. Traditional clay bricks are gradually being replaced by
auto bricks, manufactured by smart companies like NB Auto Bricks Ltd.,
using modern automated technology.
Auto bricks are known for their
uniform size, higher strength, better durability, and lower environmental impact compared
to conventional bricks. Many construction companies, developers, and government projects now prefer these
bricks because they meet modern engineering standards.
This blog will discuss the most popular types of auto bricks in Bangladesh, their features, benefits, and
common uses.
Over the past ten years, Bangladesh's construction industry has undergone significant change. Although many
builders still use conventional clay bricks, auto bricks are becoming more and more popular. These five
well-known bricks are made in automated brick factories with state-of-the-art equipment and regulated
procedures, producing higher quality and more uniform solid clay auto bricks compared to traditional
methods.
1
Solid clay auto bricks
Solid clay auto bricks are commonly used in Bangladesh & remain a familiar choice in many construction
projects. These bricks are produced from natural clay and burned in automated kilns at very high
temperatures. Because of their durability and dependable strength, many builders still rely on solid clay
bricks for different types of building work.
Key features of solid clay auto bricks
Manufactured using automated production lines
Uniform shape and size
High compressive strength
Fired at controlled temperatures for durability
Advantages of solid clay auto bricks
Strong and durable construction material
Consistent dimensions reduce mortar usage
Reliable load-bearing capacity
Typical applications of solid clay auto bricks
Residential building walls
Multi-storey construction projects
Boundary walls
Structural masonry work
2
Perforated auto bricks
Perforated bricks have a lot of holes all over their bodies. These holes reduce weight while maintaining
structural strength. Perforated bricks are increasingly used in modern urban projects because they reduce
overall structural weight.
Key features of perforated auto bricks
Vertical holes inside the brick structure
Lighter than solid bricks
Better bonding with the mortar
Advantages of perforated auto bricks
Reduced building weight
Improved thermal insulation
Efficient mortar bonding
Easier handling during construction
Typical applications of perforated auto bricks
High-rise buildings
Partition walls
Residential apartment construction
Energy-efficient building structures
3
Hollow auto bricks
Hollow auto bricks have larger cavities inside when compared with perforated bricks. These spaces reduce the
weight of the brick and also improve insulation. Because of this, many builders use hollow bricks to lower
construction costs while still maintaining good structural performance.
Key features of hollow auto bricks
Large internal hollow spaces
Lightweight design
Manufactured with automated molding machines
Advantages of hollow auto bricks
Lower structural load on foundations
Good sound and heat insulation
Faster construction process
Reduced transportation costs due to lower weight
Typical applications of hollow auto bricks
Partition walls
Non-load-bearing structures
Commercial building interiors
Apartment construction projects
4
Engineering auto bricks
Engineering bricks are specially manufactured bricks designed for high strength and low water absorption.
They are often used where structural durability is critical. These bricks are often used for projects where
strength and moisture resistance are essential.
Key features of engineering auto bricks
High compressive strength
Low water absorption
Dense structure
Produced under strict quality control
Advantages of engineering auto bricks
Excellent durability
Suitable for heavy structural loads
Resistant to moisture penetration
Long service life
Typical applications of engineering auto bricks
Foundations
Load-bearing walls
Drainage systems
Infrastructure construction
5
Fly ash auto bricks
Fly ash is a fine powder left behind after coal is burned in power plants. Many brick factories use this
material to produce fly ash auto bricks. Since it reuses industrial waste and reduces the need for clay
soil, these bricks are generally considered a more environmentally responsible option than traditional clay
bricks. These bricks have become more popular in Bangladesh as a more environmentally friendly building
material in recent years.
Key features of fly ash auto bricks
Made from fly ash, cement, and sand
Produced through automated hydraulic pressing
Uniform shape and smooth surface
Advantages of fly ash auto bricks
Eco-friendly construction material
Lower water absorption
Smooth finish that reduces plaster requirements
High-dimensional accuracy
Typical applications of fly ash auto bricks
Residential housing projects
Government infrastructure projects
Commercial building construction

People who plan to build a house or start a construction project in Bangladesh often have questions about
auto bricks. Builders, engineers, & homeowners want to understand which type of brick is suitable for their
structure and why these bricks are becoming more common. Below are some common questions that people usually
ask when learning about the different types of auto bricks used in Bangladesh’s construction industry.
Auto bricks are machine-made bricks produced in automated brick factories. The machines control the
shaping as well as the burning process. So the bricks come out more uniform than traditional kiln
bricks. Builders often select them because the quality stays consistent from batch to batch.
Many builders now prefer auto bricks because they are stronger and more uniform in size. These bricks
also reduce construction waste and as well as improve wall alignment. As modern building projects
increase in Bangladesh, the demand for auto bricks is growing quickly.
The most common types are solid auto bricks, perforated bricks, hollow bricks, engineering bricks, &
fly ash bricks. Each type serves a different purpose in construction. Builders usually choose based on
the structure, load requirements, and project design.
Yes. Auto bricks are produced under controlled conditions, which helps maintain consistent strength.
Traditional kiln bricks vary based on quality, while machine-made bricks are usually more reliable for
structural work.
Auto bricks are commonly used in residential buildings, apartment projects, and commercial structures.
They are also common in boundary walls, partition walls, and infrastructure development.
Solid bricks are fully dense and usually used where strong load-bearing walls are needed. Perforated
bricks contain small holes inside the structure. These holes reduce weight as well as help improve
bonding with mortar during construction.
Yes, of course. Fly ash bricks are gradually becoming more common. They are made using fly ash, sand,
and cement. Many builders choose them as a more environmentally responsible option compared to
traditional clay bricks.
Yes. Because auto bricks have uniform shapes and sizes, masons can place them more quickly. This
reduces adjustment work during construction & helps speed up the overall building process.
Yes. Some types, especially fly ash bricks, are considered more environmentally responsible. Modern
brick factories also make bricks with improved energy efficiency compared to older manual kilns.
Most auto bricks in Bangladesh strictly follow a standard size set by brick manufacturers and
construction practices. Although measurements may vary slightly between factories, the goal is to keep
the bricks uniform so that wall construction becomes easier and more accurate.
Yes, of course, many residential buildings in Bangladesh now use auto bricks. Their consistent size
helps create straight and stable walls, which makes construction easier for masons.
