The mortar joint having a vertical transverse plane is called which joint?

• A. Bed joint
• B. Head joint
• C. Multiwidth head joint
• D. Vertical prison

Answer: (B)

In brickwork and masonry, joints are named by the orientation of their mortar plane. A bed joint is the horizontal mortar layer between rows of bricks, while a head joint is the vertical mortar plane between bricks in the same course. A joint with a vertical transverse plane fits the head joint definition because it runs vertically between adjacent bricks across the face of the wall. The other options don’t fit: a bed joint is horizontal, “multiwidth head joint” isn’t a standard term, and “vertical prison” isn’t a masonry term. So the mortar joint with a vertical plane is the head joint.
