Construction Methods for a House Foundation

Post and Beam Foundation

• Older homes were constructed with a pier and beam -- or post and beam -- foundation; this was primarily used in pre-1960s homes. The foundation was a framework of wooden beams supported by wooden posts. This is not a very durable foundation and does not hold up well in areas where hurricanes and earthquakes are prevalent. If this method is used today, it is in wooden cabins in areas with stable ground.

Concrete Slab Foundation

• A concrete slab foundation is a single layer of concrete that is several inches thick. The slab is thicker along the edges to form a solid foundation and often rests on gravel. This type of foundation is often used in areas where the ground will not freeze and the climate does reach below freezing temperatures often. This is one of the easiest foundations to install, and the site will require minimal preparation.

Basement Foundation

• A basement foundation features poured concrete walls and flooring, and the walls support the foundation's perimeter. This space is large enough for individuals to stand upright, and the basement foundation can double as a family room or garage. This type of foundation is often found in colder climates and may add additional value to a home.

Concrete Pier Foundation

• A concrete pier foundation is made up of multiple piers located beneath the home. The advantage of using this type of foundation is that less time is spent on excavation, and it requires the use of less concrete. The concrete piers are installed anywhere from 12 to 20 feet into the ground, and reinforced steel bars tie the piers together. Once the piers are hardened, they are lifted and used as the base of the foundation. This construction method for a foundation is sometimes referred to as a crawl space foundation.
