Seismic Retrofitting

Seismic Retrofitting in Portland, Vancouver & Nearby OR Areas

The possibility of an earthquake is a reality for many Greater Portland and Oregon residents. That’s why it’s important to make sure your home is properly reinforced to resist seismic forces. Homes built before 1985 are especially vulnerable to earthquake damage. But buildings of all ages and styles can benefit from reinforcement with approved structural connectors and other structural reinforcement.

Without the proper protection, your home is at risk for major damage and is also ineligible for earthquake insurance. Find out how John's Waterproofing can help make your home safe - call us or click below to request your free seismic retrofitting inspection and estimate today!

What is seismic retrofitting?

The seismic retrofitting process involves the installation of engineered metal connectors and other reinforcement materials at key stress points throughout your home’s structure. The specially designed hardware includes hold downs, anchors & anchor bolts, strap ties, and framing angles. Wood blocking and structural sheathing may also be incorporated into many retrofitting packages.

The goal of the retrofitting process is to counteract three main earthquake-induced forces that can cause major damage to a building: racking, sliding, and overturning. In engineer-speak, the retrofitting process transforms a building with loosely connected parts into a unified structure with a “continuous load path” that extends from the building foundation up through the walls and all the way to the roof framing. Our experienced crew will utilize an impressive arsenal of seismic connectors to keep your house structure together in spite of seismic forces that can easily tear an un-reinforced house apart.


Seismic retrofitting is smart because…

  • Your home and your family will have a better chance of surviving an earthquake.
  • Proper installation of seismic hardware will help minimize earthquake damage, reducing home repair costs following a seismic event.
  • Professional retrofitting has the potential to reduce home insurance premiums.
  • A comprehensive home seismic retrofit “package” can typically be installed in just 1-2 days.
