Which type of footing is commonly used for foundation walls?

Strip footings are commonly used for foundation walls because they are designed to support load-bearing walls and distribute the weight evenly across a larger area. This type of footing entails a continuous strip that runs along the length of the wall, providing stability and preventing settlement.

In addition to this, strip footings are particularly advantageous for buildings with long, continuous walls, such as residential structures, as they allow for an efficient use of materials and are straightforward to construct. They ensure that the loads from the walls are effectively transferred into the ground, minimizing the risk of movement or failure in the foundation system.

Other footing types, such as pier footings and pile footings, serve specific purposes in different scenarios, such as supporting isolated columns or being used in deep foundations where soil conditions are poor. However, for standard foundation walls, the strip footing remains the preferred choice due to its versatility and effectiveness in distributing loads.
