A foundation is... Well, by general definition, it is the basis upon which something stands or is supported. In this case, a structure. Most of us would like to believe that a foundation will last forever, or nearly. Unfortunately, while a foundation will last a good long time, it will not be eternal. Some older concrete foundations are crumbling and in poor condition. Unwashed sand, excessive water used in the mix, and inadequate amounts of cement can all contribute to the premature failure of a foundation. Another consideration would be seismic resistance. Homes constructed in the last 20 years are much more able to withstand an earthquake than homes constructed prior to the Loma Prieta and Northridge earthquakes. If your home was constructed prior to the mid 1990s, consideration should be given to retrofit your home with seismic upgrades. A licensed structural engineer can design upgrades that will help to preserve your investment from seismic damage. With a huge amount of structural information, a great place to start is the Simpson Strong-Tie website.
