Which Foundation Type Is Best for Your New Build?

What kind of foundation is right for your newly constructed building? It’s a question many homeowners or business owners ask when building a dream home or commercial building.

Essentially, there are three types of foundations: pier and beam, slab, and crawlspace. Each has its pros and cons. Here are some of the benefits and drawbacks of each foundation type so you can choose the right one for you.

Pier and Beam Foundation

This is a common type of foundation. To construct a building, concrete piers are installed in the ground, followed by beams attached to them. The price of this type of foundation is generally higher than that of a slab foundation, but it offers a few advantages.

It offers better drainage, for one thing. This can help prevent cracks and settlements caused by hydrostatic pressure. These foundations also make it easier to access your home’s interior. In the future, if you need repairs or inspections, this can be helpful.

Slab Foundation

The most common type of foundation is a slab foundation. It is made by pouring concrete into a mold and leveling it off. Steel or mesh can be used to reinforce slabs, which are typically four to six inches thick. You can easily build slab foundations, and they provide a solid base for your home.

These foundations are prone to cracking and settling, though. If you live in an area with a high-water table, your slab foundation may crack due to hydrostatic pressure. A slab repair requires a considerable amount of professional skill if it cracks.

Crawlspace Foundation

This is the least common type of foundation. They are constructed by digging a hole in the ground and then building a frame around it. Typically, the frame is made of wood or steel and covered with a vapor barrier. Generally, crawlspace foundations are more expensive to build than slab or pier-and-beam foundations.

Still, they have some advantages. A crawlspace foundation provides better ventilation around the house. This can help prevent mold and mildew from forming. A crawlspace foundation also makes it easier to access the plumbing and electrical systems of your home. You can use this information if you need to do repairs or inspections in the future.


Choosing the right foundation for your upcoming building depends on a few factors. For example, if you are concerned about hydrostatic pressure, you may want to consider a pier-and-beam foundation. If mold and mildew are a concern, select a crawlspace foundation. In the end, the decision depends on your budget and personal preference. Whatever foundation you choose, make sure you have it inspected by a professional before you move into your new build.
