What is stepped footing foundation?
The stepped footing is also known as a Stepped foundation. The stepped footing is a simple type of isolated footing which is provided over soil having less bearing capacity. Because of low soil capacity load need to be transferred on the larger area. Stepped footing are stepped upon one another.
What is a step down foundation?
Foundations provide support for structures, transferring their load to layers of soil or rock that have sufficient bearing capacity and suitable settlement characteristics.

What is isolated stepped footing?
An isolated footing is one of the most used types of foundation to support single-columns when they are arranged at a long distance. An isolated footing must be designed to avoid exceeding its bearing capacity and provide safety against overturning or sliding while preventing the ground from settling.

10-percent slope
Footings shall be stepped where it is necessary to change the elevation of the top surface of the footing or where the surface of the ground slopes more than one unit vertical in 10 units horizontal (10-percent slope).
