What should be done to ensure stretchers are aligned in a half lap pattern?

To ensure that stretchers are aligned in a half lap pattern, cutting units at the end walls is the most effective approach. This method allows for the precise adjustment of the brick or masonry units at the edges, ensuring that they fit together seamlessly in the desired half lap configuration. By making these cuts, the installer can maintain an even, aligned appearance across the installation, which is critical in achieving both structural integrity and aesthetic appeal.

This method also accommodates the pattern's specific requirements by ensuring that the ends of the bricks at the wall matches up correctly, promoting a visually pleasing and structurally sound setup. The other options may not address the specific alignment needed for this pattern. For instance, using a larger brick might not fit within the constraints of the design, and changing the bonding style could alter the structural properties of the wall. Lastly, increasing the thickness of the mortar may result in misalignment or an undesirable appearance, rather than solving the alignment issue.
