Post and pier foundations are built on wooden posts or concrete piers set into the ground to bear the weight of the house.
This foundation is made up of a series of support piers spaced at regular intervals around the perimeter of the home, topped with beams or posts, which support the structure’s weight. It’s often used for homes which are built on sloping areas or in regions with expansive soils that can shift or settle over time. They elevate the structure, creating a crawl space between the ground and the home. This design allows for better adaptability to the shifting soil and high moisture levels.
A post and pier foundations is easier to build and less costly than the more common perimeter concrete foundations but is not appropriate for all buildings. It works best for building sites with a low likelihood of experiencing earthquake or hurricane-force winds, as these posts sit more shallow in the ground. These easy-to-build old-style foundations are more resilient than ever before, due to the advent of modern materials such as pressure-treated wood, and performed metal brackets & straps.
This is especially beneficial in the wet, rainy climate of the Puget Sound region, including areas like Seattle, Everett, Bellevue, and Tacoma.
