Why slab on grade foundation

The advantages of slab foundations are listed below. Slab foundations also have some disadvantages that should be considered. The disadvantages of slab foundation includes the followings.

Some benefits of the slab-on-grade foundation technique are that it is quite sturdy while also being relatively inexpensive. Moreover, slab-on-grade foundations are considered less vulnerable to infestation from termites and other pests because there is no hollow space between the ground and the bottom of the structure.

For more robust construction projects like that of a residence , concrete grade beams are integrated into the foundation. A stem wall foundation is poured in sections. The outside edge about 12 inches wide and just deeper than the frost line is poured first. Once the stem wall has cured, a inch slab of concrete is poured on top of it to complete the slab foundation.

The second foundation type is a pier and beam style foundation. A pier and beam foundation is made up of piers, or short columns, and beams which span the distance between the piers. In addition, since there is no crawlspace under them, utility bills associated with air conditioning and heating are lowered. The slab itself is poured in a single day. Of course, there is preparation work in advance.

The entire process can often be accomplished in four days from start to finish, assuming weather is not a problem.

Since there is no crawlspace or airspace under them, utility bills associated with air conditioning and heating are lowered. Mold and mildew are not an issue, nor or rodents or insects. They allow for a wider range of flooring options, including stained or scored concrete. Disadvantages Of Slab Foundations: The fact that they lack a crawlspace beneath them means that there is no space under the concrete slab that can be used for storage or for placing and concealing utility equipment.

As a result, all ventilation, as well as all duct work, must be installed inside walls or up in the attic area. Because the plumbing for the house is located below the concrete slab foundation, plumbing leaks require that any repairs be made by jack hammering the slab in order to fix the leak. This can create a large mess, and is also expensive to have done.
