In construction, why is it important to manage the grade away from foundation walls?

Managing the grade away from foundation walls is crucial primarily to control water drainage. This practice helps prevent water from pooling around the foundation, which can lead to various issues such as soil erosion, increased hydrostatic pressure on the foundation, and ultimately, water infiltration into the basement or crawl space. Proper grading directs rainwater and snowmelt away, promoting effective drainage and reducing the risk of structural damage caused by water.

While enhanced aesthetics, improved soil health, and landscaping facilitation are beneficial aspects of site grading, they do not directly address the critical structural concern of maintaining the integrity of the foundation. Effective water drainage remains the primary reason for managing the grade, making it essential for the longevity and durability of a building's foundation.
