What is the maximum allowable slope for footings?

The maximum allowable slope for footings is typically determined by structural engineering practices and local building codes, which aim to ensure stability and prevent potential failure due to excessive load or shifting soil. A slope of 10 units horizontal is generally considered a safe incline for footings, as it provides adequate support while reducing the risk of erosion or instability.

Footings are critical components of a structure, transferring its weight to the ground. If the slope is too steep, it can compromise the integrity of the footing by increasing the likelihood of sliding or uneven settling. Thus, maintaining a maximum slope of 10 units horizontal helps ensure that the footing remains sufficiently stable to carry the intended loads safely.
