What is the minimum grade fall away from foundation walls?

The minimum grade fall away from foundation walls is essential for ensuring proper drainage and preventing water from accumulating around the foundation, which can lead to structural problems over time. A fall of 6 inches within the first 10 feet is the standard requirement that promotes effective drainage away from the foundation, thereby protecting the integrity of the building.

This gradient helps direct surface water away from the foundation, reducing the risk of water intrusion into basements or crawl spaces and minimizing potential damage due to hydrostatic pressure. A gradual slope is essential for effective drainage systems and is explicitly outlined in building codes and regulations to ensure safety and longevity for structures. Understanding this requirement contributes to the overall skill set needed for effective construction and building management.
