The most common type of foundation in any given area varies widely depending on region. In the Kentuckiana region, we see a number of both poured concrete and masonry block foundations, so it’s best to give a quick overview of what to expect in either kind of home.
Concrete foundations are poured into a frame and formed all at once. The main benefit of concrete is that it can take any shape, drying relatively quickly and remaining strong for many years after its initial construction, if poured properly. The most appropriate framing methods can depend on the weight of the load they must bear, or on the topography, soil profile, and slope of the area. Each of the load-bearing forms are held in place by tie rods rather than mortar or other substances.
Poured walls that are damaged or cracked often require more costly repairs. Some kinds of water problems are exclusive to poured foundations—these include honeycombing and form tie leaks.
Masonry foundations, on the other hand, are assembled block by block and held together with a mortar mix. Constructed properly, they can bear just as much overhead weight as the average concrete wall; however, they are not as resistant to side pressure and may be more sensitive to underground hydrostatic changes. These foundations are sometimes favored for their smaller price tag, but often require more time and effort to build.
Generally, water-related damage to masonry foundations is easier to fix; often only a few bricks need replacing rather than an entire poured wall. For homeowners with masonry block foundations, mortar joint leakage is the problem to be on the lookout for.
