In masonry, what is the term for a brick course that projects beyond the face of the previous course?

• A. laying to bond
• B. corbelling
• C. backing up
• D. battering

Answer: (B)

Corbelling is a masonry technique where each successive brick course is laid slightly forward of the one below, producing a stepped projection from the wall face. This matches a brick course that projects beyond the face of the previous course, a feature often used for decorative cornices, arches, or cantilevered ledges. Laying to bond describes how bricks are arranged in a wall for a particular bond pattern, not a single outward projection. Backing up refers to providing support behind a finished surface, and battering means the wall slopes inward as it rises. So corbelling best describes a brick course that sticks out beyond the previous course.
