Earthquake Retrofitting

The San Andreas Fault is around 800 miles long and is just one of seven significant faults that cross the greater Bay Area. USGS researchers warn there's a 70% chance of an earthquake of a magnitude of 6.7 or higher along the San Andreas fault zone in the Bay Area before 2030.

Studies show that retrofitted homes have performed well, with little or no structural damage after a major earthquake. Simpson Strong-Tie has a complete line of seismic solutions designed and engineered to strengthen your home and greatly reduce the risk of structural damage during an earthquake.
