Foundation Series: Should I Build on a Concrete Slab?

Are you considering building a new home and you are not sure which foundation is best for you? Or, are you buying a home that is already built and you’re wondering which one is better to purchase?

In this series, we will discuss these foundation options:

  • Concrete Slab
  • Crawl Space

What is a Concrete Slab Foundation?

This slab foundation is made of concrete. They are often laid over soil-based areas by pouring the slab foundation mixture over the area and leaving it to harden.

A concrete foundation is better in a wet but not flood-prone climate where moisture might accumulate within a crawl space. The vapor barrier that lies beneath the slab will prevent mold growth from entering the home.

Concrete Slab Pros

There are multiple benefits of using a concrete slab as your foundation:

  • Better for moist climates
  • Prevents mold growth in the home
  • Steps are not necessary
  • Less expensive
  • Faster to construct
  • Less subject to pests and vermin
  • More energy efficient
  • Stronger and more durable

Concrete Slab Cons

Here are some of the cons of using a concrete slab as your foundation:

  • Cracks easily with shifting soil
  • Floods more easily
  • Ductwork and plumbing are less accessible
  • Can be damaged by tree roots
  • Repairs are more expensive

Back before the 1970s, homes were built with a crawl space structure or a full basement. Since then, however, concrete slab, foundations have become more popular.


A slap can help insulate a home by eliminating the free-flowing air under the floor that is present with a crawl space. This can save on heating and cooling bills. Even a well-insulated floor cannot help a crawl space match the energy savings of a slab foundation since outside air still circulates beneath the subfloor causing temperature fluctuations in the home.


A concrete slap makes for a hard surface  to stand and walk on. Even the best floor coverings will not make the floor as forgiving as a floor built over a crawl space. These floors, or at least the subfloors are usually wood. This makes them more comfortable walking surfaces.
