Which masonry bond is made primarily of alternate courses of headers and stretchers?

The masonry bond that is characterized by alternate courses of headers and stretchers is known as the English bond. In this bond, each course consists of alternating rows: one row of headers and the next row of stretchers. This configuration provides a strong structural integrity while also achieving aesthetic appeal. The headers, which are laid flat, help bind the structure together, while the stretchers run along the length of the wall, offering more surface for mortar adhesion.

This technique is particularly effective in ensuring that the load is distributed evenly across the wall, making it a preferred choice in both structural and decorative masonry applications. The combination of headers and stretchers also contributes to the overall resilience of the wall, allowing it to withstand lateral forces and other stresses that may be imposed on it.
