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 what type of foundation you have – and what you need to know about it.


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


Typically built with cinder block and brick facing, crawlspace 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.

Crawlspace foundations last up to 50 years, and they are more vulnerable to mold and fungi.


A basement foundation consists of an 8-foot-deep hole with a concrete slab at the bottom. The walls are typically made of cinderblocks, and the process of pouring the foundation makes it waterproof.

With a lifespan of up to 100 years, basement foundations are preferred because of their durability and resistance to fire and extreme weather. They also add square footage to the home and provide extra storage space.

Pier and Beam

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.

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

It is recommended that this foundation type only be built in areas not prone to hurricane-strength winds or earthquakes.
