In typical wall construction, which bond ties the wall together with headers in some courses?

• A. Running bond
• B. Stack bond
• C. Common bond
• D. Flemish bond

Answer: (C)

In brick masonry, the way bricks are arranged to interlock across the wall and tie its different parts together is called the bond. When headers are included in some courses to lock the wall across its thickness, that pattern is common bond. The main idea is to mix a few courses of stretchers to form the body of the wall and insert header courses at intervals to connect the outer and inner wythes, providing structural cohesion and resisting separation. This approach uses headers only some of the time, which is why it’s described this way. Running bond uses only stretchers with no headers, so it lacks that cross-wall tying. Stack bond keeps bricks aligned in vertical lines, offering less interlock and stability for typical walls. Flemish bond has headers in every course, alternating with stretchers within each course, so it doesn’t match the notion of headers appearing only in certain courses.
