Bond with vertical alignment?

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

Answer: (C)

Vertical alignment in brickwork happens when every brick sits directly on the one below, so the vertical mortar joints line up in straight columns along the wall. That pattern is known as stack bond. It creates a clean, uniform look and is quick to lay, but it provides less interlock and shear resistance than bonds that stagger joints, so it’s typically used for non-structural walls or decorative veneer rather than load-bearing walls. Other bonds intentionally offset joints—running bond shifts each brick over the one below to form continuous horizontal courses, while Flemish and English bonds mix headers and stretchers to build stronger interlock—so their joints do not align in a single vertical plane.
