Foundations provide support for structures, transferring their load to layers of soil or rock that have sufficient bearing capacity and suitable settlement characteristics.

Strip foundations (or strip footings) are a type of shallow foundation that are used to provide a continuous, level (or sometimes stepped) strip of support to a linear structure such as a wall or closely-spaced rows of columns built centrally above them.

The natural surface of ground may be sloped, with the most economical solution being a stepped foundation. This helps to minimise the amount of excavation and below-ground wall construction that would otherwise be required. The foundation takes the form of a series of concrete horizontal steps following the slope of the ground. Stepped foundations can also be used to transition deep to shallow foundations, and at corners and intersections.

Each step of the foundation should be no higher than the thickness of the concrete foundation. The foundation at the higher level should also overlap the lower foundation by at least 300 mm.

The drainage must be carefully designed to catch water from the upper side of the embankment and to channel it safely under or through the embankment, therefore eliminating any danger of instability due to water pressure.

On sloping sites the stepping of straight runs of foundations is necessary to cater for the changing depth of the foundation and to avoid abrupt and excessive steps in the foundation that could cause a weakness and result in movement. Similarly abrupt and excessive changes in foundation depths should be avoided at corners and intersections by the introduction of a stepped detail.
