What Type of Foundation Do I Have?

June 12, 2020 Baird Foundation Repair

The foundation is the first and most important part of building a house, and knowing about it is an important part of maintaining your home.

There are several different home foundation types, and each has varying characteristics. Here’s a list to help you figure out which type you have – and what you need to know about it.

Slab-on-grade foundation

A slab-on-grade is one of the most common foundation types. It consists of a flat pad of concrete on which the house is built. Steel reinforcing bars (rebars) and wire mesh run through the concrete. The concrete is about two feet deep around the perimeter and six inches deep everywhere else.

A quality slab-on-grade foundation lifespan is around 100 years. Slabs don’t work well in cold climates, as the concrete could shift in freezing temperatures. However, slab-on-grade is the recommended form of foundation in warmer climates, and installation is simple.

Crawl space foundation

Typically built with cinder block and brick facing, crawl space foundations raise the house about two feet off the ground. They are popular in moist climates because the house is lifted off the ground. This stays safe from damage caused by water that accumulates.

Crawl spaces last up to 50 years, but they are more vulnerable to mold and fungi.

Pier and Beam foundation

Pier and beam foundations are made from wooden or concrete beams set deep in the ground. They bear the weight of the building which is typically held 18 inches off the ground. Utility units are installed in the resulting crawl space.

Pier and beam is popular because it is easier and less costly to build. This system should be used for smaller buildings. Its lifespan highly varies, depending on the material used and the surface it is built on.

Pier and beam is recommended to only be built in areas that are not prone to hurricane-strength winds or earthquakes.
