Seismic retrofitting is technical work which is also known as earthquake retrofitting. The seismic retrofit methods we use is more than what would be termed as “foundation bolting”. Seismic retrofitting involves foundation anchors (or foundation bolts), shear panels, and framing connectors, each element installed to specific engineered standards.
No house is the same although many share basic and fundamental foundation construction types.
