The termite-proof base, 12 years old, as long as the chemical barriers remain intact. A concrete slab foundation poured with a block base can last 100 years or more, more than one service life, if properly designed.

Quarterly pest control and annual termite inspection will help you stay aware of this potential problem.

The foundations on which your home is built can have a big impact on the structural integrity of your home. A slab base is made of concrete that usually has a thickness of 4 to 6 in the center. The concrete slab is often placed on a layer of sand for drainage or to act as a cushion. A slab base is a large, thick concrete slab that is used as the substructural base of a house, which is the lowest part of a load-bearing building and extends below ground level. Since its design is simple, there is not much that can go wrong.

Therefore, if built correctly (which is usually the case), concrete slabs will last at least 50 years and probably much longer. Meanwhile, homeowners don't have to do much, other than occasional inspections to make sure there are no cracks present. Both a concrete slab and a crawl space base will be durable if professionally built with quality materials in a properly prepared lot. A concrete base is expected to last about 50 years or more, barring any changes in the earth below the intrusion of concrete or tree root. A crawl space has approximately the same life expectancy, except for any violent flooding or insect infestation.

When the concrete around your building starts to deform, it can jeopardize the structural integrity of the foundation. A concrete slab base is usually installed on a property that, as it should be, has been graduated. A concrete slab base is better in a humid climate, but not prone to flooding, where moisture can accumulate inside a crawl space. However, the most important factors in resale value are how the foundation fits in with the foundations typical of the surrounding area and how well it is built.
