Why should I retrofit?
Reduce Housing Loss
Seismic retrofit of older buildings is the best tool for reducing housing losses. A recent study found that for every $1 spent on mitigation, you can save $3 in earthquake losses. Retrofit also protects investments, keeps residents in their homes, and keep communities intact.
Small Investment Yields Protection
Retrofitting of anchorage is a high priority because it provides a very large earthquake bracing improvement at a very small cost. Dwellings that slide off of their foundations due to lack of anchorage to the foundation have been very commonly seen in moderate to major earthquakes. Many older buildings were constructed without anchor bolts, or have too few or inadequately installed bolts. On the west coast anchor bolts became common in approximately the 1950’s
