The purpose of a pier and beam foundation primarily includes allowing airflow underneath the house. This type of foundation consists of piers that elevate the structure above the ground, creating a crawl space. The space underneath the home facilitates ventilation, which is crucial in preventing moisture buildup and the growth of mold or mildew. Proper airflow helps maintain the integrity of the wooden beams and flooring and aids in climate control within the home by allowing cooler air to circulate during warm months.

While solid ground support is also essential, pier and beam foundations specifically focus on creating elevated space and ventilation, distinguishing them from other types of foundations that are designed primarily for stability and load-bearing purposes. Thus, improving air movement underneath the structure is a prominent function of this foundation type.
