A building’s foundation is the structure upon which it rests. The foundation keeps the building stable even when there is a slight shift in the land. A concrete slab foundation is sometimes called a mono slab or monolithic foundation. They are a cost-effective and affordable type of foundation. This type of foundation is built by creating a concrete slab placed on the ground. The house is then built on this slab. Wooden foundations became popular in the 1960s. Builders make use of wood that is not susceptible to decay. It is important to note that wooden foundations do not last as long as concrete foundations. However, most people use wooden foundations because they do not require intensive labor. A basement foundation is a type of foundation dug about eight feet deep. This type of foundation creates space for underground space. Most people prefer a basement foundation because it provides extra space.
