Concrete slab foundations are the most popular type found in the United States as well as in most other regions of the world. It is inexpensive, easy to install and maintain and provides the home with a considerable amount of protection from the elements. Concrete is made from gravel, water and cement, a mix that creates a very hard substance that is effective at maintaining the stability of a home.
Stability and Shifting
Concrete slabs are extremely stable, providing the home with increased support and firmness. It is cheaper than most foundation types to install due to its commonness and it gives the home a durable base. Shifting naturally occurs in most foundation types due to the movements of the earth and soil, but concrete does not shift as much, remaining in position beneath the house.
Protects Interior Furnishings
Concrete slabs are more water resistant than other types of foundations, providing protection from rising water tables. They are also fire resistant, which provides some protection for the upper levels of the house in case of exterior fire. In cases of interior fire sources, the concrete helps to contain the flames somewhat, providing the homeowner with an opportunity to evacuate the home in time.
This type of foundation provides excellent thermal conduction, storing the heat of the day and releasing it gradually at night when it is cooler. This explains why concrete floors always seem to be really cold to the touch, because they send the heat out into the room. This built-in feature will help prevent over-use of space heaters and furnaces, plus, concrete lasts much longer than other foundation types and is simple to maintain, providing it has been installed correctly.
