What is the main purpose of footings under foundation walls?

Provide an initial water stop to prevent water from entering the cellar or basement
Provide a level surface for erection of forms
Provide added strength to foundation walls
Reduce bearing load on soil

The correct answer is: Reduce bearing load on soil

The primary purpose of footings under foundation walls is to effectively distribute the weight of the building across a larger area of soil, thereby reducing the bearing load on the soil. Footings are designed to extend below the frost line and provide stability to the structure by preventing settling or shifting due to soil movement. This is crucial for maintaining the integrity of the foundation and the overall structure. While footings do contribute to the overall strength of the foundation walls and can provide a level surface for formwork during the construction process, their primary function is to manage how weight from the structure is transmitted to the ground. This distribution helps to prevent issues such as cracking, settling, or heaving that can occur when insufficient support is provided for heavy loads. Thus, ensuring the footing's proper design and installation is essential for the longevity and safety of the building.
