In which bond pattern are CMU walls almost always laid?

CMU (Concrete Masonry Unit) walls are almost always laid in a running bond pattern due to the structural advantages it provides. In a running bond, each course of blocks is staggered, meaning that the vertical joints of adjacent courses do not align. This configuration enhances the overall stability and strength of the wall, reducing the risk of cracking and increasing resistance to lateral forces.

The running bond also allows for better load distribution across the wall, as the overlapping of the blocks creates a more unified structure. This pattern is not only functional but also efficient for builders, as it is simpler and faster to lay out, helping to speed up the construction process. This makes it the preferred method for constructing CMU walls in both residential and commercial applications.
