What course is typically run every 16 inches in masonry work?

The correct answer indicates that a mortar joint is typically run every 16 inches in masonry work. In masonry construction, the mortar joint plays a crucial role in binding bricks, blocks, or stones together while also allowing for some flexibility and movement. The 16-inch spacing is commonly referenced as a standard practice for ensuring proper alignment, structural integrity, and aesthetic consistency throughout the masonry assembly.

While the other choices deal with different aspects of masonry or materials used, they do not adhere to the practice of being placed at a specific vertical interval in the way that the mortar joint does. For instance, a brick course refers to a row of bricks laid in a wall, but the mortar joint is the spacing or material that separates and supports those courses. Identifying the importance of mortar joints and their regular spacing is essential for anyone involved in masonry construction or practices.
