Basements are popular in Northern States, but not as popular in the West and here in the South. In fact, the overall popularity of basement foundations has been dropping over the past 20 years. In this video, we’re going to look at how basements are constructed, different types of basements, and their pros and cons and the reason for their downtrend.

Basements serve the same purposes as other foundation types; they distribute a building’s weight evenly, they secure it into the ground and they keep moisture out.

A full basement matches the perimeter of the house above. Full basements can be insulated and installed with drywall and flooring, providing living and storage space. They are the most expensive foundation and they are susceptible to mold, mildew and moisture. Daylight or walkout basements are built when the building rests on a slope: One side of the basement is fully submerged, while the other is aboveground. As the name suggests, daylight basements can have large windows and doors to bring in natural light. They aren’t as susceptible to mold, mildew or moisture. Crawl spaces are a type of basement with limited use. Crawl spaces are the least expensive type of basement foundation since they don’t require as much excavation. Lastly, a cellar is a room underground that is often used to store canned goods, fruits, vegetables, wine or general storage.

Now let’s look at the general advantages of basements. The first and probably the most important is access to utilities like plumbing, electrical wires and even under floor ventilation systems. T Finished full basements can boost home values by increasing the usable footprint. They are naturally insulated by the earth so they need less energy to heat or cool rooms. Basements also provide shelter incase of a tornado or hurricane so you find yourself in this situation.

Even with all these advantages, there are many drawbacks to basements which is causing a downtrend in their popularity. The first and most obvious is the cost of building basements. Soils play a big role in the feasibility of building basements. There are large areas in the US with clayey soils. Because of the small size of its particles, clay is good at holding water. It also dramatically expands and contracts as it takes on water. This puts immense lateral pressure on basement walls, which would lead to water in the basement even if there was no rain. Another disadvantage of basement construction is dealing with the climate, in particular, the frost line. When you build a home, the foundations need to be below the depth of the frost line.

Another very important factor leading to the downtrend of basement construction is the risk of leaks, mold and mildew. Basements are often exposed to more water than standard foundations. There’s one more reason why basements are declining in popularity. Since 2008, the homeownership rate has stayed below 65%. More people rent houses or apartments in complexes. In conclusion, the rising cost of materials and waterproofing issues are two of the main reasons why basements are no longer popular. It costs more to build than the value it will add to the property.
