In masonry work, what is the purpose of a raked joint?

A raked joint is primarily designed to create a recessed look for aesthetic purposes. This type of joint involves intentionally leaving the mortar joint uneven or recessed, which can enhance the visual appeal of a masonry wall. The raking of the joint allows for more light and shadow to play on the surface, giving the wall a textured appearance. This technique is often employed in decorative masonry work to elevate the overall design and complement architectural styles.

In addition to aesthetics, raked joints can also have some functional benefits, like potentially helping with water drainage, although this is not their primary purpose. The enhanced appearance often becomes a significant consideration, especially in high-visibility projects where the attractiveness of the masonry work is paramount.
