Why soaking of bricks is done before construction?

Bricks should be soaked in water before use in any construction works.

Wetting of bricks removes any dirt, sand and dust from them. Soaked bricks prevents suction of water from the wet mortar. If dry bricks are used then it will absorb water from mortar and mortar will become dry and cannot attain any strength.Bricks should be soaked in water for such a time period so that the water penetrates the whole depth of the brick. However bricks should not be soaked for a long period of time.However there are also some disadvantages of it.There will not be proper adhesion between mortar and brick.Brick may slip over the mortar creating difficulty in ensuring plumbness of the wall.
