The spiral Bricklay pattern is used in conjunction with which bricklay pattern?

• A. One-two
• B. Even-odd
• C. Block-layout
• D. Circular

Answer: (A)

A spiral effect in bricklaying needs a repeating, small offset that you can carry from one course to the next without creating long, continuous joints. The one-two bricklay pattern provides that simple, predictable rhythm, so each course advances the wall with a consistent offset. That steady, incremental shift lets the line of bricks gradually twist, producing the spiral while keeping joints staggered and the structure stable. The other patterns don’t support this smooth, cumulative rotation: block-layout rests on a rigid grid, circular focuses on curvature rather than a gradual twist, and even-odd follows a different joint alignment that doesn’t yield the same spiral progression. So, the spiral bricklay pattern is used with the one-two bricklay pattern.
