8 MUST FOLLOW RULES FOR GOOD BONDING IN BRICKWORK

bonding in brickwork

Bond in brickwork refers to the method of arranging bricks into courses so that individual brick units are bound together and the vertical joints of successive courses are not in the same vertical line.

purpose of brick bonding

  • Gain maximum power while distributing the load it can carry over a wall, column or pier.
  • If the bonds are not arranged properly in brickwork, a continuous vertical joint will result. It is called a non-binding wall with low strength and stability. (see fig. below)

  • To ensure lateral stability and resistance to side thrusts.
  • To make an acceptable appearance.

Bonding Rules in Brickwork

The following rules must be followed to get a good bond.

rule 1

Bricks should be of uniform size. The length of the brick should be twice its width and one joint to obtain a uniform lap. Good binding is not possible if the laps are uneven.

Rule-2

The amount of lap should be at least the length of a brick along the length of the wall and brick length across the wall thickness.

Rule-3

Avoid using bricks unless necessary or necessary in special places.

Rule-4

In elective courses, the midline of the header must coincide with the midline of the stretcher, in the course below or above it.

rule-5

Vertical joints in alternate courses must be along the same vertical axis.

Rule-6

The stretcher should only be used in the facing; They should not be used in the heart. Hearting should be done in the header itself.

Rule-7

It is preferable to provide every sixth course as a header course on both sides of the wall.


Rule-8

The use of rakes and other joints providing horizontal water table should be avoided. Concave and weathering joints should be provided.
