What type of construction uses joint reinforcement every second course?

The type of construction that uses joint reinforcement every second course is known as a stack bond wall. In a stack bond wall, the bricks are laid in a vertical alignment, with all joints directly stacked over one another. This method generally requires reinforcements to help maintain structural integrity and provide stability, especially since there is a lack of horizontal interlocking between the courses of bricks. By placing joint reinforcement in every second course, the design helps to ensure that the wall can better resist lateral forces and mitigate potential cracking or failure due to load imbalances.

In comparison, other types of bonds, such as common bond walls, typically feature a pattern that includes both stretchers and headers, allowing for greater stability without needing reinforcement in every second course. A running bond wall also focuses on a pattern where bricks are joined at staggered intervals but does not require reinforcement in the same way as a stack bond wall. Alternate bond is not a standard term recognized in this context and generally would not refer to a specific construction method that involves such reinforcement patterns.
