How do you determine the thickness of a mortar joint?

The determination of the thickness of a mortar joint is pivotal in bricklaying, not only for structural integrity but also for aesthetic appeal. The standard thickness for mortar joints tends to vary according to the type of masonry being done, but typically, a thickness between 10 to 12 mm is widely accepted in the industry, particularly for standard brickwork.

This range helps to ensure the proper bonding and distribution of the mortar, allowing for effective load transfer and providing suitable space for the mortar to fill the gaps between bricks, accommodating slight irregularities in the brick dimensions. It also accounts for any shrinkage that may occur as the mortar sets and dries, contributing to a durable finish.

This knowledge is crucial for a bricklayer, as it influences not just the appearance of the final structure but also its overall performance. Maintaining the correct joint thickness as per the standard practices can help prevent issues such as cracking or failure in the masonry over time.
