Lesson 11 : Bonds In Brick Work

Facing Bond

This Bond is used where bricks of different thickness are to be used in the facing and backing of the wall. In this bond, a header course is provided after several stretcher courses. Since the thickness of bricks are different in the facing and backing, the vertical distance between the successive header course is kept equal to the least common multiple of the thickness of backing and facing bricks. Thus, if the nominal thickness of facing bricks is 10 cm and that of backing bricks is 9cm, the header course is provided at a vertical interval of 90 cm. This type of bond is not structurally good and load distribution is not uniform
