Seismic Retrofit Methods & Services
Seismic Retrofit Methods
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. There are five basic construction types that are found in Portland and the seismic retrofit method for upgrading each will vary. Select your foundation style to learn more about the custom seismic retrofit method that would be used to bolt your home to the foundation.
- Concrete Wall (Full Height & Crawlspace)
- Cripple Wall (Full Height & Crawlspace)
- Slab on Grade
- Unreinforced Masonry
- Post & Pier
It is not uncommon for homes to have two to three types of foundation construction. For example 1960’s & 1970’s ranch split style houses can have both full height, cripple wall, and slab on grade styles of foundation construction. We specialize in Custom Seismic Retrofits for each and everyone of them.
In addition to foundations the following areas of your home should be considered for earthquake proofing:
- Hot Water Tank Seismic Strapping
- Chimney Seismic Retrofit
- Garage Seismic Retrofit
- Gas Earthquake Shut Off Valve Installation
