Foundation bolting "house bolting" is a process of attaching a house to its concrete foundation.
The up-and-down and side-to-side motion of an earthquake can result in an unbolted house to move right off its foundation.
(Residential & Multi-family dwelling)
Seismic retrofitting is the modification of existing structures to make them more resistant to seismic activity, ground motion, or soil failure due to earthquakes.
