What is Earthquake Fastening?

We can start by closely examining the various earthquake fastening techniques. Each one has its place and purpose, ensuring homes are reinforced in the most effective way possible.

Foundation Bolting: This is often the first line of defense. The idea behind foundation bolting is pretty straightforward – securely attaching the home to its foundation. This technique typically involves drilling into the home’s existing foundation and installing bolts that link the home to its base. It’s essential in preventing the house from sliding or toppling off its foundation during an earthquake.

Cripple Wall Bracing: Next up, we have cripple wall bracing. This technique is specifically designed for homes with a crawlspace between the home’s first floor and its foundation. These “cripple walls” can collapse during an earthquake if they’re not properly reinforced. To prevent this, plywood is typically used to brace these walls, creating a sturdier structure that can better withstand the shaking during an earthquake.

Installing Shear Walls: Lastly, we’ve got the installation of shear walls. These are specific types of walls designed to resist lateral forces, like the ones produced by an earthquake. They’re typically made of stiff panels, like plywood, and are fastened to the framing of the house. Shear walls provide additional strength and stiffness to the structure, helping it to resist the forces that earthquakes generate.

The Crucial Role of Retrofitting in Vintage Homes

Choosing the right technique, or combination of techniques, depends on a variety of factors. The style and age of the home, its existing structure, and the nature of the seismic risk in the area all play into this decision. It’s always best to work with an experienced professional who understands both the intricacies of your home and the seismic realities of your region.

Unveiling Damping Systems: An Integral Part of Seismic Retrofitting

Damping systems are technologies designed to absorb and dissipate the energy generated by seismic activities, reducing the extent of oscillations a building might experience during an earthquake. By doing so, these systems help prevent or lessen structural damage, enhancing the overall resilience of the building.

Types of Damping Systems in Seismic Retrofitting

Damping systems used in seismic retrofitting can be broadly classified into the following categories:

  • Viscous Damping Systems: These systems employ fluid-filled devices to absorb the energy generated by an earthquake, similar to how shock absorbers work in a car.
  • Friction Damping Systems: These systems use mechanical friction between surfaces to reduce seismic energy.
  • Metallic Yielding Damping Systems: These systems use specially designed metallic components that yield under seismic loads, absorbing energy.
  • Elastomeric Damping Systems: These systems use rubber-like materials to absorb and dissipate seismic energy.

How Do Damping Systems Work in Seismic Retrofitting?

Regardless of their type, all damping systems work by converting the seismic energy into another form, primarily heat, and dissipating it, thereby preventing the energy from being transferred to the building’s structure.

The Benefits of Using Damping Systems in Seismic Retrofitting

There are numerous benefits to incorporating damping systems into your seismic retrofitting strategy:

  • Improved Building Safety: By reducing the energy transferred to the building during an earthquake, damping systems can prevent structural collapse, significantly enhancing the safety of the building’s occupants.

When you think of Seattle, WA, the Space Needle, Pike Place Market, or its famous coffee culture might spring to mind. However, for seismic retrofitting specialists, Seattle’s dense urban landscape of multi-story buildings also presents a critical challenge. 

Understanding Soft-Story Buildings

Before walking through the retrofitting techniques, it’s important to understand soft-story buildings. Soft-story buildings are multi-story structures, typically residential, where the ground floor is significantly weaker than the upper floors due to large openings such as doors, windows, or garages. While aesthetically pleasing and functional, this design is highly vulnerable to seismic activities.

Common Seismic Retrofitting Techniques

Now that we’ve established the importance of seismic retrofitting let’s discuss some of the common techniques employed by professionals in Seattle:

1. Shear Walls

Shear walls are a popular retrofitting technique. These are solid wall segments installed on the weak ground floor to increase the lateral stiffness of the building, thereby reducing the chances of collapse during an earthquake.

2. Steel Frames

Another common approach is installing steel frames. Steel is extremely resilient, and when strategically placed, these frames can provide excellent support and increase a building’s resistance to seismic forces.

3. Cantilevered Columns

Cantilevered columns involve the addition of reinforced concrete or steel columns to existing weak columns. This method is often employed when other retrofitting techniques are not feasible due to architectural or space constraints.

4. Moment Frames

Moment frames are hinged connections that allow for rotation and bending during a quake. These frames help distribute the seismic forces more evenly, reducing the impact on the weaker lower stories.

5. Seismic Dampers

A more technologically advanced solution is the use of seismic dampers. They work similarly to shock absorbers in cars, reducing the magnitude of vibrations and, thus, the overall damage.

6. Base Isolation

Base isolation is a technique that involves installing flexible bearings or pads between a building’s foundation and structure. In an earthquake, the building moves with the ground, reducing the seismic energy transferred to the structure.

We Love Our Customers!

We would definitely hire this company again. They had good communication; were prompt; respectful of our property; and completed the work in less time than expected. In general, they did a great job.


Evergreen Seismic came up in a Google search when I was questioning whether my earthquake insurance was really necessary, so I called and owner Matt came out for a free inspection. It turned out that our house did have some risk factors and Matt explained what he recommended and how they would do the job. After some research, I decided to proceed. They just finished after less than a week and Matt and his crew were thoroughly professional and friendly. I especially appreciated Matt's willingness to take extra time explaining things and he even offered some free advice on a couple of unrelated areas where some foundation repair was needed. A residential seismic retrofit isn't cheap and like any insurance, you hope you won't need it. I'm happy with the quality of the work performed and the price. I would recommend Matt and Evergreen Seismic to anyone thinking about making their home more earthquake tolerant.


We worked with Evergreen Seismic in the Summer of 2023 to retrofit our Seattle home. From the very first meeting, we knew that Matt was the right person to trust this project to. He is very knowledgeable and competent, and our communication was always transparent and smooth. Evergreen Seismic coordinated the process of getting the proper permit from the city (which took some time since we were using the standard set of plans) and provided us with all the documentation. When the time came for the retrofit itself, it was performed quickly and efficiently, in just one day for our one-story, 3-br. home. The city inspector was happy with the job as well! We confidently recommend Evergreen Seismic and Matt to anyone planning a seismic retrofit work in the Seattle area.


Evergreen Seismic was amazing to work with. Matt was quick to respond to our initial query, and took the time to walk us through the process and answer questions when he came out to look at the house. His bid was very clear and thorough. He's also a great communicator and made the whole process extremely smooth once we decided to go forward. We really appreciated that nothing felt rushed or unexpected. The crew here doing the work was considerate, patient with any questions we had, and kept us updated every day about what was going on. They did a really great job retrofitting our basement and crawl space and took care of some necessary repairs as well. We were lucky enough to have Evergreen recommended to us, so passing on the recommendation now! We would hire them again with zero reservations.


Evergreen Seismic and Matt were such blessings to us during our seismic retrofit on a Bellevue home we just bought! Matt and his crew, Phil and Nick, were all equally tremendous and beyond helpful to us and my inlaws! We were hell bent on seismically retrofitting by removing drywall interiorally vs sidings exteriorally. And Matt was accommodating to our request. As a hedge though, we knew we wanted a contractor who knows how to retrofit by both methods should a need arises during the retrofit peocess! And Matt fits the bill with his extensive knowledge and years working in earthquake retrofitting. They say never open up drywall if you don't want to find out what deep dark secrets lie underneath. And boy, did we unearthed a structurally problematic framing job on most all the studs holding up an exterior wall of the house, which threw my husband and I in a loop thinking of the scope creep. But Matt stuck with us, helped to sister in all new 2x4s on the compromised studs, and best yet didnt charge us an arm and a leg to fix the framing issue because he truly cares about doing the best job at the most economical rate. The framing job along with the seismic retrofit all easily passed various round of inspections. What started as out as contractor/client relationship became friendship based on what transpired with our house framing issue. We can only hope to find contractors as knowledgeable and honest as Matt and crew!


I would hire Matt again in a heartbeat. Not only do he and his crew perform good work (in my case, seismic retrofit) at a fair price, he combines his core competencies with great people skills and clear, timely, winsome communication. I am especially grateful to Matt because he was ever so patient with me when I suffered long COVID a few weeks after signing the contract, prompting me to delay the project a few months while I recovered. Matt turned what I expected to be a stressful experience into a very good experience. I encourage anyone considering a seismic retrofit to invite Matt to visit you and give you an estimate. I expect that you, too, will be highly satisfied with the result.


Matt did a fantastic job on the earthquake retrofit for our home. Our garage had never been so clean as it was after he was done with his work. Matt had the utmost professionalism through every step of the project. The contract clearly explained everything he was going to do, and he completed every step exactly as described. He thoroughly answered each of my questions during his initial visit in a way where he not only answered the question I asked, but gave background information to educate me on the topic of seismic retrofit. It's great to have the peace of mind that not only is my home now better able to withstand the "big one" that will eventually come to the PNW, but also that the work was done by a great company.


Matt is knowledgeable and competent, and he communicates clearly before and during the job. He made sure that we knew what our options were, and that we understood them. Matt is a friendly, likable person and obviously cares about doing a professional job. He wants his customers to be happy. It was soon clear that we could count on Matt and his team to show up on time and also to clean the site each day before they left. They worked all day each day until the project was finished. I would certainly recommend Evergreen Seismic to anyone who wishes to retrofit their home. I have confidence now that my 1901 home is in much better shape to withstand a significant earthquake without coming off the foundation.


Matt came out to see if our house needs a retrofit and I was absolutely blown away by his honesty, knowledge and professionalism. He advised against retrofitting our house due to the newer age of the home but did provide me with a tonne of useful information that I did not come across during my research and while speaking with other retrofit companies.


I was extremely pleased with the seismic retrofitting job Matt and his team completed for me. The entire experience was seamless. Matt was extremely informative during the bidding process and everything was completed on time and to a high standard. The work site was cleaned everyday and work plans and schedules were clearly communicated. It's obvious that Matt and his team really care about performing quality work. To echo another review, if I could hire them for all my home renovations, I would.
