What is the role of a slab in foundation design?

A slab is a vital component of the foundation design. It is a flat, horizontal concrete structure that serves as the base on which the building sits. The main function of a slab is to distribute the weight of the building evenly across the soil, providing a stable and level base for the structure. It also helps to protect the building from moisture intrusion and provides significant resistance against horizontal forces like wind, earthquakes, and soil pressure. A well-designed slab is crucial to the structural integrity and long-term performance of the building.
