Introduction of Types of Brick Bond
Brick masonry is one of the oldest and most useful building materials used in the world. Brick masonry is widely used in building elements as a durable form of construction.
The building masonry is constructed by placing several bricks in a proper sequence on the mortar. Through which the resistance of the imposed load can be safely transferred.
Bonding is important in brick masonry. The method of arranging bricks in mortar in masonry construction is known as brick bonding.
What Is Types of Brick Bond?
In brick masonry bricks are laid in a pattern. Thus, the arrangement of bricks in the construction of brick masonry is called a brick bond. In brick masonry, various brick patterns are made in their own appearance, installation difficulties, and structural structure in the case of walls.
Brick masonry work uses bricks of the same size in most all bonds. Or at least a matching size brick is used. In brick masonry, this is done using the appropriate pattern of brick on the bed of mortar. Evidence of various patterns of brick masonry can be found in all the ancient and historical buildings.
The strength of brick masonry depends on the type of brick bond and the type of material. Brick Bond plays an important role in providing strength, stability, and durability of brick masonry.
Types of brick bonds in brick masonry The different type is provided depending on the style of placing bricks in the walls and the binding style. Brick masonry is developed by filling mortar in layers and joints using a brick bond. In which the bricks in the wall are laid side by side and in layers.
Type of Brick Bond
- Header Bond
- Stretcher Bond
- English Bond
- English Garden Wall Bond
- Flemish Bond
- American Bond & Scottish Bond
- Raking Bond
1. Header Bond
The short square face of the brick in the header type of brick bond is 9cm x 9cm. Header bonds are known as heading bonds. In header bonds, all the bricks in each layer in masonry are placed as headers on the face of the walls.
This type of brick bond allows better alignment for curved walls. In the header bonds, the thickness of the brick becomes 18cm thick.
2. Stretcher Bond
Stretcher bond in brick is the simplest brick pattern. But stretcher bonds cannot effectively bond in 18-inch brick masonry. This type of stretcher bond is used especially in partition walls.
Stretcher bonds are commonly referred to as running bonds. In this type of stretcher bond, only the length of the brick is laid. This type of bricklayer pattern overlaps the bricks below and above.
Brick masonry using stretcher bonds does not have enough stability to stand alone in case of long span and height. Thus, a supporting structure like brick masonry or column is needed to support the brick masonry made in the stretcher bond.
Stretcher bonds are commonly used as an exterior face in reinforced concrete framed structures of high-rise buildings. This type of stretcher bond is also used as the outer face of boundary walls, gardens.
3. English Bond
The English bond of brick masonry is made using a layer of the stretcher and a layer of the header above it. Thus, this type of brick pattern has a repetition of stretcher and header.
To break the alignment of verticle joints, brick masonry is constructed using the first header and lastly the Queen Closer. Quinn Close is a form of a brick cut in two lengths. It is used in the corners of brick walls.
4. English Garden Wall Bond
The pattern of bricks in the English garden wall is similar to the English bond. In this type of brick bond, the heading course is inserted only after every 3 layers. And stretchers brick pattern is used in 3 layers. In short, this type of brick bond brick masonry uses one course of headers and three courses of the stretcher.
The vertical joint is arranged in the header coarse using the queen closer.
5. Flemish Bond
Flemish bonds are also known as Dutch bonds. The flemish bond brick pattern is made by placing headers and stretchers in a single layer course.
Flemish bond brick pattern, the header rests in the middle of the stretcher in the course below. In Flemish Bond brick masonry, the course of each layer starts with a header in the corner.
Flemish bond thickness is usually at least one full brick. Flemish bonds are difficult to use as brick masonry. Flemish bond requires more skill in arranging bricks. All vertical mortar joints need to be aligned for the best effects of the Flemish bond pattern.
Flemish bonds can be divided into two types:
5.1. Single Flemish Bond
In single Flemish bond, English bond and Flemish bond are used in brick masonry. This brick pattern has a Flemish bond as the face of the wall. And English bond support in the baking course.
A single flemish bond cannot be used in a brick masonry less than one or half a brick in thickness. Single Flemish Bond is used in brickwork to ensure full strength and to give an attractive appearance of Flemish Bond.
5.2. Double Flemish Bond
In double Flemish bond, each course represents the same brick pattern in both front and back elevation in brick masonry. In each course, the headers and stretchers are arranged on a mortar. This type of brick masonry bond is used keeping in mind the economy and appearance. The bond in this type of brick bond is usually weaker than the English bond.

6. American Bond & Scottish Bond
In the Scottish Bond, the stretchers course is used 5 times consequentially under the header course. While in American Bond the header coarse is followed by 7 times consequently brick masonry in the coarse.
The arrangement of bricks is laid in brick masonry at any angle except zero or ninety degrees. This brick pattern helps to increase the stability of the thick walls formed in the English bond. This brick bond is arranged at certain intervals along with the wall height of the brick masonry.
The brick masonry of the racking bond is represented in three brick patterns.
7.1. Herring-Bone Bond
This type of brick bond is suitable for very thick walls in brick masonry. In this type of bond, the brick pattern is the laying of bricks in a 45-degree course in two directions from the center. This type of brick bond is mostly used for brick paving.
7.2. Diagonal Bond
This type of brick bond is suitable for walls of two to four brick thicknesses. Diagonal bonds with wall height are usually represented every fifth or seven-course. This types of bond is arranged with a stretcher face.
7.3. Zig Zag Brick Bond
In the case of brick masonry in a zig-zag bond, the bricks are laid in a zig-zag pattern. This type of brick bond is especially used in brick flooring.
