How far above grade must parge extend?

Parging is a finishing coat applied to masonry surfaces, and in construction, it serves as an important element for protection and aesthetics. The requirement for how far above grade the parge must extend is primarily aimed at preventing moisture infiltration and damage to the underlying masonry.

When parge extends 6 inches above grade, it provides a sufficient barrier against water splashing and accumulation that could otherwise deteriorate the masonry walls. This height is generally recognized in building codes and best practices to ensure that the parging effectively shields the wall from potential water exposure and helps direct moisture away from the foundation.

While other heights such as 2 inches or 4 inches can provide some degree of protection, they may not be sufficient against typical conditions where water might splash against the walls or accumulate around the foundation. Extending the parge to 6 inches above ground level ensures compliance with safety standards and longevity of the structure’s components.
