Concrete Crawl Space

A crawl space with a concrete floor either with or without foundation vents

This type of crawl space is not as common but has its advantages. For one, this type of construction is more energy efficient than an open crawl space if constructed without foundation vents.


The concrete crawl space uses mainly two different types of ventilation:

  1. Foundation Vents


  1. Ventilation using the forced air (furnace) system of the home

Durable storage option

Although most crawl spaces are too short for this option after the home is built, it offers a lasting means for durable storage.

A bit more costly

Gaining the durable storage does come with a price, usually adding several thousand dollars to the construction costs.

A cap on the odor

A crawl space with a concrete floor has far fewer odor problems than an open crawl space.

The Cons-

  1. Some are constructed with foundation vents
  2. Most are poured as a “mud pad”. A mud pad is a rough poured concrete slab that’s sole purpose is to cap the earth under it- usually without a vapor barrier between the concrete and the earth. Therefore, there is little to no protection for the crawl space against moisture penetration through the (non vapor barrier) floor and the walls.
  3. If conditions change and a water problem shows up it can be very expensive to install a drain system in an existing concrete floor crawl space due to the height.
  4. When installing a concrete floor in a crawl space after the home is built will cause very high moisture in the crawl space due to the drying and curing process. This will go away, but will need to me managed to prevent any new issues.
  5. Not a DIY Project

What is crawl space encapsulation?

Crawl space encapsulation is a generic term used to describe a crawl space that is protected from moisture by using a crawl space vapor barrier on the floor and walls. There are different ways to accomplish this, as well as different results, depending on the "system" you purchase. If you hire a company or franchise to finish your crawl space make sure you get the most for your money. Crawl space encapsulation alone will help reduce moisture and improve the environment of the crawl space, but there are other components to consider like; the quality of the crawl space vapor barrier, how to close the foundation vents permanently, crawl space insulation, sealing the crawl space vapor barrier to the foundation wall, conditioning the crawl space, crawl space moisture control and lowering the homes energy costs.
