A slab foundation is just a slab of concrete that a house is built upon. A slab foundation generally sits upon a footing that has been built below the frost line. The concrete piece is usually 4 to 8 inches in density with embedded steel rods called “rebar” to prevent breaking and faulting. The house structure is constructed straight on the soil without any basement or crawlspace. All water lines and midsections are set up prior to the concrete being poured.
One of the main reasons slab structures are popular is the cost factor. Slab foundations are the least costly and the quickest to set up. Slab structures minimize the cost of the whole building simply due to the fact that the house is constructed directly on the piece. That saves the expense of flooring joists that would typically support the building. Slab foundation houses are easier to heat since there is no airspace under the house impacting the interior temperatures.
Because there’s no basement or crawlspace all ventilation duct-work should be channeled through the attic and through spaces in the walls. There is no extra space for utilities and no storage, the whole home is generally sitting on a large platform of solid concrete. Although slab foundations are the least expensive house foundations to construct, they’re the most expensive to fix. All the plumbing for the house is basically under the concrete piece making it impossible to repair without tearing up concrete flooring which is now part of the interior of your house. Leaks are tough to identify due to the fact that they’re under the slab and in many cases go undetected for years. An uncommonly high water bill is the first sign that you may have an underground leak.
Disadvantages of Basement Home FoundationsThe main disadvantage of the basement is that since a large part of it is below ground level they are vulnerable to leaking and mold development. In locations with a high water table is sub pump might be set up to combat flooding. Basement home foundations are the most costly to construct due to all the additional product required and time to construct it. This additional expense throughout building and construction will make your home simpler to keep. A home with a complete basement usually has a higher resale worth than either of the previous types of house structures discussed.Read More
