Bricks can be stacked in a variety of ways, but typically there are only two common options when it comes to installing bricks: The running bond and the stack bond.
The running bond is the most common type of brick pattern, one seen in walls and buildings all over the globe. It’s simple and straightforward even if it isn’t fancy. Structurally it offers plenty of strength to the wall. Since the courses alternate, with centers alternating from course to course, the pressure works down to offer stability. The running bond is common because it’s easy to execute and does exactly what it’s supposed to do, even if it doesn’t look especially dramatic.
In a stack bond the bricks are literally stacked on top of each other and held by mortar. It can look effective, but there’s no strength in the wall. If a stand bond wall is going to stand it will need to be secured to a metal plate at the back or be supported in some other way. That’s its great drawback. If just used for decoration it can look excellent and act as a focal point for the eye. For construction, however, the running bond wins.
