Bed Joint

Term from Bricklaying industry explained for recruiters

A bed joint is the horizontal layer of mortar between bricks or concrete blocks in construction work. Think of it as the "glue" that holds rows of bricks together. When looking at a brick wall, the bed joint is the flat horizontal line of mortar you see between each row of bricks. The quality of bed joints is crucial because they affect both the strength and appearance of the wall. Similar terms you might hear are "mortar joint" or "horizontal joint." This is a fundamental skill in bricklaying and masonry work that appears frequently in job descriptions and evaluations of craftsperson's work.
