Question: 1 / 400

Which bond pattern alternates rows of headers and stretchers in a 3:1 ratio?

English Bond

The pattern that alternates rows of headers and stretchers in a 3:1 ratio is known as the English Bond. This masonry bond consists of alternating rows, where three stretcher bricks are followed by one header brick. This creates a strong, visually distinct pattern that is useful for structural integrity and aesthetic appeal.

In contrast, other bonding patterns such as Common Bond typically use a 5:1 ratio of stretchers to headers, alternating coursing, while Flemish Bond features headers and stretchers in each course, but with each header alternating with a stretcher. American Bond combines elements of both, also primarily focusing on stretchers but usually reserving headers for specific courses. Understanding these patterns is vital for construction practices, as they influence the strength and stability of brick walls.
