When you look into any building structure, walls play a major part. Every wall has its unique Brick masonry technique, which will play the main role in the stability of the structure. But you know what Brick masonry is?
It’s the basic construction technique that has evolved over time. From traditional methods to modern innovations, brick masonry continues to be a cornerstone in construction projects across the world.
Keep on reading this blog to learn more about Brick masonry’s types, importance, and construction guide.
What is Brick Masonry?
Brick masonry is a procedure of setting bricks in an organized way in the mortar. It is a long-lasting and proficient method in construction. Various types of mortars and bricks, with different applications and characteristics, compose a brick wall that withstands external loads.
Here, the bond that binds the bricks together results from filling suitable mortar in the joints between the bricks. The placement and mixing of mortar need special focus in brick masonry as they are central to the longevity and functionality of the structure.
Significance of Brick Masonry
Brick masonry carries significant importance in construction for many reasons:
Energy Efficiency
Brick masonry reduces the heat transfer through masonry brick walls. Irrespective of the hot and sunny outside, the bricks take a long time to absorb that heat and transfer it to the interiors completely. Also, it maintains the heat inside the home remains trapped for a longer duration during the cold months. So it is energy efficient.
Better Longevity
Brick masonry is a good choice for enduring and economical construction Because it neither fades nor needs continuous maintenance like drywall.
Fire Protection
One of the major advantages of brick masonry is its inherent fire safety. It does not fuel fires or emit toxic gases, even in the case of fire. This makes it a natural fire barrier, ensuring the safety of your buildings and the people within them.
Reduction of Noise
The mass of brick masonry also prevents the noise outside from pervading the interiors, and the thickness of the walls decreases sound transmission in the interiors.
Some Basics for Brick Masonry
Understanding the basics of brickwork, including types of bricks (like clay and concrete) and bonds (such as stretcher and header), is crucial for ensuring structural stability and aesthetic appeal. Knowledge of these fundamentals helps to choose the right materials and techniques for better masonry construction.
Types of Bricks Used in Brick Masonry
Following are the general types of bricks used in brick masonry
Common Clay Bricks
These bricks are made by baking wet clay in an oven at high heat. They’re strong and tough, so they’re used a lot in building houses, especially where there’s plenty of clay around.
Engineering Bricks
These bricks are super tough and made with the best clay. They’re heated at high temperatures to make them strong and resistant to chemicals and water. They’re used in buildings where strength is crucial.
Fly Ash Bricks
These bricks are a smart way to recycle materials from coal power plants. They mix the leftovers from burning coal with other materials and convert them into bricks. They’re strong and good for the environment.
Concrete Bricks
These bricks are made from sand, cement, water, and big bits of stone. They’re convenient because you can make them right where you need them and change their size to fit different jobs. They’re used for lots of different building projects.

Types of Bond in Brick Masonry
There are numerous types of bonds used in brick masonry. The major types are:
Stretcher Bond
When you lay bricks so only the long sides show, halfway covering the ones above and below, that’s a stretcher bond. It’s the simplest brick pattern.
Header Bond
In this type of bond, each row of bricks is placed with the short end facing out, which is called a header. You can also call it a heading bond.
English Bond
The bricks are laid with a mix of long and short sides. Some rows have the short end facing out (header), while others have the long side showing (stretcher). Sometimes, special bricks are placed at the corners to break up the straight lines.
Flemish Bond
This is a unique and eye-catching pattern where each row has a mix of long and short sides showing, like an English bond. But in Flemish bond, each row alternates between headers and stretchers, creating a captivating checkerboard effect that’s sure to impress.

Brick Masonry Types
The brick masonry types can be divided into mud brickwork and cement brickwork.
Brick Masonry with Mud
Mud/clayey soil has been used as a building material for ages. In mud brick masonry, mud serves as the mortar. Bricks are bonded through a mud mixture, which is more flexible than cement mortar. This particular type of brick masonry offers different benefits, including cost-effectiveness due to its usage of local materials, good insulation against heat, ease of work with and repair, and buildings with natural shine.
Mud brickwork is the cheapest way to build with bricks, but it has some drawbacks. Instead of cement mortar, builders use mud to fill the gaps between the bricks. These mud gaps can only be 12 millimetres wide. Mud brickwork works best for buildings that are no taller than four meters.
Cement Brickwork
As the name suggests, bricks are laid in cement mortar in this case. Cement brickwork can be further subdivided into three categories: first class, second class, and third class.
Brick masonry with cement is the most commonly used type in modern construction. It uses cement mortar as the binding agent to create robust and long-lasting structures. Bricks are arranged in various patterns, like stretcher or header bond, based on the design needs. This brick masonry type provides strong, stable, and durable buildings.
This brick masonry type offers benefits such as high structural strength and durability, resistance to moisture, fire and pests, a wide range of design possibilities, and a modern and clean aesthetic.
Construction Procedure for Brick Masonry
- First, mix the mortar with water until it’s smooth and easy to work with.
- Then, spread the smooth mortar evenly along the base-line using a wide tool called a trowel.
- Next, place the first row of bricks in the mortar. Put mortar on the end of each brick and firmly press it into place so the mortar squeezes out from the sides.
- Use a level to make sure the row is straight.
- Add another layer of mortar on top of the first row to start the second row.
- Start the second row with half bricks to make sure the rows are staggered for stability.
- Continue adding bricks, making sure to keep them straight and using a level to check at each step.
- Continue doing this process for every row until you reach the desired height.

How to Improve the Quality of Brick Masonry?
Following are some tips to make your brickwork better:
- Make sure walls are at a perfect 90-degree angle and avoid gaps between rows of bricks.
- Fill every vertical joint with mortar during the pointing in construction to keep moisture out and make the structure strong.
- You must know before plastering that scrape the brick surface 12 mm deep for a smoother finish.
- Spray a bit of water on the surface before laying new bricks.
- Keep mortar joints less than 12 mm thick.
- Build brick structures at a pace of one meter per day.
- Wait at least seven days for the mortar to fully set before using the brickwork.
- Over time, brick masonry has improved, making it even more valuable in construction.
Conclusion
Brick masonry is a major element in construction, acting as the backbone of numerous structures worldwide. By understanding its types, bonds, and construction procedures, one can get its potential to create robust and visually appealing buildings. With attention to detail and keeping the best practices, brick masonry continues to be refined and perfected, ensuring both longevity and a better outlook in construction projects. As we aim for excellence in brickwork, we honour its legacy while embracing the innovations that move it forward, increasing its indispensable role in the built environment.
