What type of bond is used when all units are laid in a single direction?

The type of bond used when all units are laid in a single direction is known as the running bond. Running bond is characterized by a straightforward and uniform alignment of individual bricks or blocks, where each unit is laid with one end on the center of the unit below it. This method creates a simple pattern where all the bricks are staggered in just one direction, contributing to both structural stability and aesthetic appeal.

In contrast, other bonding types introduce variations in patterns, such as the English bond, which alternates courses of headers and stretchers, or the Flemish bond, which features alternating headers and stretchers within the same course. Stacked bond, while similar in appearance to running bond, typically lacks any horizontal staggering, leading to vertical joints aligning directly above one another, which can compromise structural integrity. Each of these bonds serves distinct purposes and effects in masonry construction, making running bond the straightforward choice for uniform alignment.
