ENGLISH BOND COMMONLY USED
FLEMISH BOND APPEALING
STRETCHER BOND USED AS PARTITION WALL
HEADER BOND USED WHERE CURVED WALL IS REQUIRED.
RAT TRAP BOND - HAS CAVITY AND ACTS AS THERMAL RESISTANCE TO BUILDING AS WELL AS ECONOMICAL.
4. ENGLISH BOND
The facing bricks are laid in alternate courses of
headers and stretchers.
Queen-closer inserted next to quoin-headers to
produce overlap.
Avoids continuous vertical joints.
DISADVANTAGE:
Penetration of damp through transverse joints.
Appearance not as good as Flemish bond.

7. FLEMISH BOND
Double Flemish bond
Single Flemish bond
The headers and stretchers alternate in
each course.
The lap is produced by placing a queen-
closer next to the quoin-header in every
course.
Flemish bond is weaker than English bond.
8. In Double Flemish Bond, each course presents
the same appearance both in the front and back
elevations.
Every course consists of headers and stretchers
laid alternately.
This type of bond is best suited from
considerations of economy and appearance.
It enables the one brick wall to uniform faces on
both the sides.
9. Single Flemish Bond:
It is a species of bond in which placement of
Flemish bond on the face of the walls.
the rest of the wall is built in English bond.
Used for walls requiring a good appearance and
strength.
Not employed for wall less than 1 and a half
bricks thick.
ADVANTAGES OF FLEMISH BOND:
It is highly economical.
Walls one brick in thickness are easier to
produce a fair face on both sides in Flemish than
in English bond.
The appearance of Flemish bond is more
appealing to eye than that of English bond.

12. HEADER BOND
It is the bond in which all the bricks are laid as
headers on the faces of walls.
There is use of three-quarter bats in each
alternate courses as quoins.
This bond usually suitable in case of curved walls
but is not preferred for straight walls as it does not
have strength in the direction of the wall.

14. STRETCHER BOND
•In this bond all the bricks are laid as stretchers
on the faces of walls.
•This pattern is used only for half brick thick
walls i.e. 9cm, such as partition walls, walls,
division wall.
•This bond is not possible if the thickness of wall
is more.
15. RAT TRAP BOND
•It is made by placing the bricks on their sides
having a cavity of 3″
•Alternate course of stretchers and headers.
•It is still used in India as an economical bond.
16. THE ADVANTAGES OF RAT TRAP BOND:
It is highly economical because:
Can make a wall of one brick thickness with
fewer bricks than a solid bond.
Strength is equal to the standard 9″ (230 mm)
brick wall, but consumes 20% less bricks.
Maintains thermal comfort inside the building
due to air medium.
Bricks aligned on both sides, plastering not
required.
