Types of Most Popular Bonds used in Bricks Masonry Work

In this article, you will learn the different types of Bond used in Brick Masonry Work. Brick Bonds increase the strength and durability of masonry. It also enhances the outer visual appearance. In order to install a different type of bond requires skilled manpower. Bricks masonry is made with bricks and bonded together with the help of a mixture of cement, sand, and water. Let’s have a look at some of the popular bricks bond used to construct Masonry Walls.

Types of Popular Bonds in Brick Masonry Wall

Stretcher Bonds in Brick Masonry

  • The longer face of bricks seen in elevation is known as stretcher face. The brick size of 190 mm x 90 mm is the stretcher’s face.
  • In this type of bond, bricks shall be arranged in a stretcher course.
  • While laying the brick masonry with this type of bond, the vertical joint of each stretcher course should not be in the same line.
  • In order to break the vertical joint, we have to provide half brickbat at end of each alternate course starting from course second.
  •  If the vertical joints are in the same line, overturning of brick masonry may occur when it is subjected to lateral forces. Hence this type of wall is not used for structural purposes.
  • This type of bond is generally used to construct the half brick thick partition wall.

Header Bond

  • The shorter face of bricks seen in elevation is known as header face. The brick size of 90 mm x 90 mm is the header face.
  • In this type of bond, bricks shall be arranged in the header courses.
  • This type of bond is used to construct brick thick walls.
  • This type of bond is used to construct an external wall, curved wall, foundation, etc.
  • While laying the brick masonry with this type of bond, the vertical joint of each header courses should not be in the same line.
  • In order to break the vertical joint, we have to provide two 3/4th bats at the junction in the first course and then we start placing the header along the length. In course 2, 3/4th brickbat shall be provided at the junction in header face and then header face brick shall be placed continuously along the length.
  • The wall having this type of bond is not good for load-bearing structure.

English Bond

  • In this bond, the bricks are laid in alternate courses of headers and stretchers.
  • This type of bond is stronger than the Stretcher and header bond.
  • The wall having this type of bond is good for load-bearing structure.
  • With this English bond, one brick thick wall and half brick thick walls are constructed.
  • In order to break the continuity of vertical joints, brick is cut in lengthwise into two halves and used at the beginning and the second last brick at the end of wall of header course. This type of brick is known as queen closer.
  • To construct one brick thick wall, In First Courses two stretchers are placed in the beginning and continued up to required length of the wall. In the Second courses, we place header first and queen closer in the beginning and in end in order to break the vertical joint with the adjacent course.

Flemish Bond in Brick Masonry

  • In this bond, the bricks are laid in alternate headers and stretchers in each course.  Courses should start with a stretcher and header.
  • In order to break the vertical joints, the queen closer is required, if a course starts with a header.
  • There are two types of Flemish bond i.e. Double Flemish bond and single Flemish Bond.
  • In Single Flemish Bond, the outer face of walls has a Flemish look i.e. alternate stretcher and header in each course whereas inner face of walls has an English bond.
  • In Double Flemish bond, both face i.e. inner or outer face of wall has alternate header and stretcher in each course.
  • This type of bond is used for aesthetic view. It required good skill manpower to construct a Flemish bond.

Rat Trap Bond

  • In this type of bond, bricks are laid in vertical position hence cavity is created inside the wall of one brick thickness.
  • The arrangement pattern of the Rat trap Bond is similar to the English and Flemish bond.
  • The main difference is that in English and Flemish bonds, Bricks are placed in a horizontal position whereas in rat-trap bond bricks are placed in a vertical manner.
  • Due to the cavity inside the walls reduces the cost of construction, material requirement and enhances the thermal efficiency without compromising the strength of the wall.
  • Arrangement of rat trap bond resembles with Double Flemish bond in one brick thickness.
  • Due to the vertical positioning of bricks, the height of the wall is automatically increasing hence required fewer bricks.
