What is the minimum slope percentage for ground directly adjacent to the foundation?

The correct answer is: 2%

The minimum slope percentage for ground directly adjacent to a foundation is 2%. This requirement is set to ensure proper drainage away from the foundation, which is crucial for preventing water accumulation that can lead to structural issues such as cracking, settling, and moisture intrusion. A slope of 2% means that for every 100 units of horizontal distance, there should be a 2-unit drop in elevation. This gentle slope effectively directs rainwater and surface runoff away from the foundation, mitigating the risks associated with water erosion and foundation damage. Recognizing the importance of maintaining this slope can significantly contribute to the longevity and integrity of a building. While steeper slopes may provide better drainage, they can also pose challenges in certain landscaping and construction scenarios. A slope percentage less than 2% would not be sufficient to ensure that water drains away effectively, potentially leading to problems over time.
