A wall that looks straight from a distance can still be out of plumb, and the difference shows up months later as cracked plaster or doors that will not close. Good masonry starts before the first brick is laid: bricks must be soaked in water for a few hours until air bubbles stop rising, because a dry brick will suck moisture straight out of the mortar and weaken the joint. Every brick is laid frog up, so the mortar fills the frog and locks the brick in place, and joints are kept a uniform 10 to 12 mm, never thick and never squeezed to almost nothing.
Bond pattern matters as much as the mortar. English bond, alternating courses of headers and stretchers, gives strong, straight walls and is the most common choice for load-bearing brickwork in Indian houses, while Flemish bond alternates header and stretcher within the same course and is often chosen for appearance. Blockwork with AAC or concrete blocks follows the same discipline of level, plumb and uniform joints, though joint thickness and mortar mix can differ slightly from brick practice, so always check the block manufacturer's guidance.
The mason's basic tools, line and pins, spirit level, and plumb bob, are checked after every course, not just at the end of the day, and it is disciplined site practice to limit masonry height to about 1 metre per day so the fresh work below does not squeeze out under the weight of new courses. Where one section of wall must stop and a new one continue later, proper toothing, leaving a stepped edge, is preferred over simple racking wherever the design allows, since a properly toothed joint bonds far better than a butt joint filled in afterward.
Mortar joint thickness
10-12 mm
Max masonry height per day
~1 m
Remember on site
- Soak bricks fully, lay frog up, and keep joints uniform at 10-12 mm
- Use English bond for strength or Flemish for appearance; check level, line and plumb every course
- Limit masonry to about 1 m height per day and prefer toothing over simple racking at stop-ends
