- Before using the bricks in construction it should be checked for its physical properties (such as strength, dimension, water absorption etc).
- Bricks must conform to the designer’s specification.
- Prior to use bricks in construction, it should be soaked in water for sufficient time so that the water penetrates the whole depth of brick.
- After completion of the soaking period, bricks should be removed from water and allowed to become surface dry, before use in construction.
- Always laid the bricks having its frog facing upward.
- The mortar should completely cover the bed and sides of the bricks.
- During laying bricks on mortar bed, it should be slightly pressed into the mortar bed to ensure good bonding and uniform joint thickness.
- During laying bricks should also be pressed sideways, to have uniform thickness of vertical joints.
- All the joints in brick masonry should be so filled with mortar that no cavity is left in between.
- Brick work construction should be started from its end or corners and it should be carried out perfectly in line.
- The brick work should be perfectly in level.

- At plinth, window sill, floor level, roof level and at the top of the parapet wall, the brick course should be laid with bricks on edge.
- Iron fixtures such as hold fasts for doors & windows etc, should be embedded in cement mortar or cement concrete.
- In case the wall face is to be plastered, all joints should be raked to a minimum depth of 10 to 15 mm. this raking is done when the mortar is in green condition.
- If no plaster has to be done on wall surface, then joints in the wall surface should not be raked at all.
- At every 30 m to 45 m length of wall, provide expansion joints of about 18 mm to 25 mm
- After construction of brick masonry, it should be cured properly for a period of 1 to 2 week.
