Frequently Asked Questions
Seismic retrofitting strengthens existing structures to withstand earthquake forces. It typically involves reinforcing foundations, walls, and connections to improve a building's resistance to seismic activity. This process reduces the risk of collapse or significant damage during an earthquake, protecting lives and property.
Los Angeles is located in an active seismic zone, making it prone to earthquakes. Seismic retrofitting is crucial for older buildings that were not built to current seismic standards. Retrofitting helps minimize damage and ensures the safety of occupants during an earthquake, reducing the risk of injuries and fatalities.
