The grade away from foundation walls must be a minimum of?

The correct response indicates that the grade away from foundation walls must be a minimum of 6 inches in the first 10 feet. This specification is crucial for proper drainage and preventing water from pooling around the foundation, which can lead to structural damage over time. By ensuring that the ground slopes away from the foundation, it helps direct rainfall and surface water away, thus reducing the risk of water infiltration into the basement or foundation area.

Maintaining this gradient is an essential practice in construction and landscaping because it contributes to the durability of the structure. If the slope is insufficient, it can lead to issues such as mold growth, foundation settling, and increased maintenance costs associated with moisture-related problems. This requirement is guided by best practices in building regulations and is essential for safeguarding residential and commercial properties alike.
