A common type of foundation utilizes vertical concrete walls, typically short, which elevate a structure above the ground. These walls sit atop a footing, which is a wider base that distributes the building’s weight over a larger area of soil. For example, in residential construction, these walls often form the perimeter of a crawl space or basement, providing a solid base for the house’s framing.
This type of foundation offers several advantages. It can protect structures from moisture damage by raising the building above ground level, reducing the risk of flooding and pest infestation. Furthermore, this foundation provides a level building surface on sloping lots, simplifying construction and potentially reducing excavation costs. Historically, these raised foundations have been employed in regions prone to flooding or where soil conditions are unstable.
