How much should brick stacks taper back for every foot of height above the 4' level?

The correct answer indicates that brick stacks should taper back by 2 inches for every foot of height above the 4-foot level. This tapering is a crucial aspect of masonry construction, as it helps to ensure stability and structural integrity as the height of the brickwork increases. Tapering is implemented to distribute the weight of the bricks more evenly and to prevent excessive lateral pressure that could lead to buckling or failure of the stack.

The practice of tapering back brick layers helps in creating a better bond and can improve the aesthetic appearance of the structure. Understanding this tapering requirement is essential for builders and contractors to follow best practices in construction and to comply with local building codes which may stipulate specific tapering standards for safety and durability.
