What bond consists of ALL stretchers and is mainly used in cavity wall and veneer wall construction?

The bond that consists of all stretchers and is primarily utilized in cavity wall and veneer wall construction is the running bond. In this bricklaying pattern, every row of bricks is offset from the row below it, which ensures a smooth appearance and effective load distribution. This alignment helps in the thermal and moisture control of the veneer walls, making it an ideal choice for these specific types of construction.

The running bond's continuous horizontal alignment allows for efficient brick placement and can enhance the structural integrity of the walls. It is less labor-intensive compared to other bonds and provides a uniform look that is aesthetically pleasing.

In contrast, the other options present variations in brick layout. The stacked bond consists of bricks stacked directly on top of each other in perfect alignment, lacking the staggered effect of the running bond. English bond alternates rows of stretchers and headers, which gives it different load-bearing characteristics and is not exclusively made up of stretchers. Flemish bond requires alternating stretchers and headers in each row, which creates a complex pattern that is not suited for cavity wall applications in the same way as the running bond. Thus, the running bond fits the specific needs of cavity wall and veneer wall construction more effectively.
