Oregon Seismic retrofits are completed to the highest technical standards and comply with Federal Emergency Management Agency, 2012 International Existing Building code (IEBC) and City of Portland prescriptive guidelines for residential structures.

Each retrofit is designed based on the technical needs of your home, and may include:

Installation of Simpson Strong-Tie structural anchoring systems to engineered standards.

Reinforcement of the connection between the sill plate and flooring system.

Installing post caps to ensure an adequate connection between beams and posts.

Reinforcement of cripple walls to improve shear strength.

Concrete foundation crack repair.

Installation of earthquake-activated gas line shut-off valves.

Water heater strapping.

We secure permits for all work performed.

So happy to have worked with Oregon Seismic on our earthquake retrofit. The bid was the lowest one we received, they were very professional and well-organized, and the city inspector said that the retrofit was perfectly done. Thanks!
