How far must masonry walls extend above finished grade?

The requirement for masonry walls to extend above finished grade is important for ensuring proper drainage and preventing moisture intrusion into the structure. Extending the masonry walls at least 6 inches above the finished grade helps to keep water from pooling around the base of the wall, which can lead to deterioration over time. It creates a barrier that diverts water away from the structure, protecting against issues such as rot, mold, and structural weakening.

This specification is grounded in building codes and best practices that prioritize durability and the longevity of construction. By adhering to the 6-inch requirement, contractors help ensure that their buildings remain safe and stable throughout their lifespan. Going beyond 6 inches may not be necessary in most cases and could be seen as unnecessary expense, while less than 6 inches would be insufficient for effective water management.
