Seismic Fastening for Critical Infrastructure: Lessons from Recent Earthquakes

Seismic Fastening for Critical Infrastructure: Lessons from Recent Earthquakes

Critical infrastructure owners, such as bridges and power plants, know the importance of having their buildings withstand seismic activity. In a world where earthquakes can cause significant destruction and devastation in a matter of seconds, these structures must be prepared for shaking ground. Recent earthquakes around the globe and here in Kent, WA, have highlighted the need to ensure proper earthquake and seismic fastening techniques are used when constructing and installing critical components within structural frameworks.

In this blog post, we talk about what we’ve learned from recent earthquakes and why using the proper seismic fastening is so important when building or fixing important infrastructure.

The Importance of Seismic Fastening for Critical Infrastructure

Seismic fastening may not be the most glamorous subject, but it is certainly one of the most important. Critical infrastructure, such as hospitals, airports, and power plants, must be designed and constructed to withstand the force of an earthquake.

Without proper seismic fastening, these structures are at risk of experiencing severe damage or even collapse during a seismic event. The consequences of such damage can be catastrophic, leading to injuries, loss of life, and massive disruption of essential services. The importance of seismic fastening for critical infrastructure cannot be overstated; it is essential for ensuring the safety and resilience of our communities in earthquake-prone areas.

Best Practices for Seismic Fastening in Critical Infrastructure

These practices ensure that the infrastructure can withstand the vibrations and shaking caused by earthquakes. Utilizing advanced technologies, such as base isolation and energy dissipation systems, can help prevent damage and keep people safe.

Engineers must consider factors like soil type, building shape, and materials used when designing seismic fastening systems. It’s important to invest in high-quality materials and testing procedures to ensure the best possible protection for critical infrastructure.

Protecting Seattle’s Historic Homes from Earthquakes with Seismic Retrofitting

Protecting Seattle’s Historic Homes from Earthquakes with Seismic Retrofitting

Seattle is no stranger to earthquakes, and its historic homes are particularly vulnerable to seismic activity. Fortunately, seismic foundation retrofitting can help protect these structures from the worst of a major quake. This blog post will discuss the basics of seismic retrofitting and how it can help preserve the city’s history. 

What is Seismic Foundation Retrofitting? 

Seismic foundation retrofitting is a process in which structural elements are added or reinforced to make a building more resistant to shaking caused by an earthquake. This type of retrofitting typically involves reinforcing the foundation or walls of a structure and strengthening any parts of the building that may be weak or prone to collapse. It is important to note that not all buildings require seismic retrofitting; however, those located in areas prone to earthquakes should consider it. 

The Benefits for Historic Homes 

Seismic retrofitting has many benefits for historic homes in Seattle. Since these buildings were constructed before modern building codes, they may not have been designed with earthquakes in mind. As such, they are more likely to suffer significant damage during an earthquake than newer structures. 

By strengthening them with seismic retrofits, these homes can better withstand major quakes and remain standing even after the worst has passed. Additionally, seismic retrofits can help reduce damage caused by minor tremors regularly occurring in Seattle and other quake-prone areas. 

In addition to providing physical protection against earthquakes, seismic retrofits also offer financial benefits for homeowners in Seattle’s historic neighborhoods. 

Since these buildings have been around for decades, their value has increased significantly over time—but this value could be lost if they were destroyed during an earthquake and had to be replaced with new construction. By protecting them with seismic retrofits, homeowners can ensure that their investments remain safe from potential disasters and continue to appreciate over time.  

Evergreen Seismic Is Keeping Seattle Safe

Evergreen Seismic is proud to be protecting Seattle’s historic homes from the dangers associated with potential seismic activity. Our seismic foundation retrofitting provides additional reinforcement against earthquakes, helping keep these treasured buildings safe for generations.

Earthquake and Seismic Fastening For HVAC Ductwork

Earthquake and Seismic Fastening For HVAC Ductwork

If you live in an area prone to earthquakes like Kenmore, it’s crucial to ensure your HVAC system is securely fastened in place. Not only can adequately installed and secured HVAC systems help protect the safety of your home during an earthquake, but they can also reduce damage to the system itself. So what’s involved in earthquake and seismic fastening for HVAC ductwork? Let’s take a look.

Earthquake and Seismic Fastening For HVAC: The Basics

Earthquake and seismic fastening involve securely attaching HVAC systems to walls or ceilings using a variety of specialized hardware.

This helps keep the system in place if there is an earthquake, reducing the risk of the system becoming damaged or dislodged. It also helps keep the system from becoming a hazard—if it falls during an earthquake, it could cause injury or further damage.

The type of hardware used for seismic fastening depends on the material being attached (e.g., wood, drywall, concrete) and the weight of the object being attached.

For example, heavier objects such as air conditioning units may require more secure installations than lighter objects such as vents or ductwork. In most cases, it’s best to consult a professional to determine which type of hardware will best suit your particular situation.

Why Should I Secure My HVAC System?

In addition to helping protect your home against earthquakes and other natural disasters, properly installed and secured HVAC systems can also help reduce energy costs.

If a system isn’t firmly attached, air leaks can occur around loose joints or gaps, leading to higher energy bills due to lost air—air that needs to be replaced by running fans longer than necessary or running extra cycles on your furnace or air conditioner.

The cost savings from having a properly secured system are significant enough that many homeowners install seismic-rated anchors even if they don’t live in areas known for earthquakes or other natural disasters.

Newest Advances in Earthquake and Seismic Fastening For Your Home or Business

Newest Advances in Earthquake and Seismic Fastening For Your Home or Business

Earthquakes can tremendously damage Seattle homes and businesses while also causing life-threatening situations. That’s why homeowners, business owners, and contractors must stay updated on the newest advances in earthquake and seismic fastening systems. Let’s look at some of the latest advances available for improving seismic protection in your home or business. 

Earthquake Resistant Bolts 

Installing earthquake-resistant bolts is one of the most widely used methods for strengthening a structure during an earthquake. These bolts are designed to absorb shocks from seismic waves and keep your building intact. 

They are made up of two parts—the head, a thick metal plate attached to the wall, and the body, which consists of two plates connected with large nuts and washers. Earthquake-resistant bolts come in various sizes and can be customized to fit any application. 

Seismic Isolation Systems 

Seismic isolation systems are another way of providing additional protection against earthquakes. These systems work by isolating a structure from ground movements during an earthquake. 

This isolation reduces the amount of energy transmitted through the structure during a seismic event, thus reducing damage and potential loss of life due to the collapse or destruction of the building’s foundation system. Seismic isolation systems can be installed either before or after construction has begun on a building, depending on its location and design needs.

Base Isolation System 

The base isolation system is one type of seismic isolation system that has gained popularity due to its ability to provide more effective protection against earthquakes than other methods, such as structural braces or friction pendulums. 

The base isolation system works by separating a structure’s main support columns from its foundations using flexible bearings that allow vertical movement but restrict horizontal movement between them during an earthquake.

This reduces strain on both the foundation and main support columns while still allowing them to move independently during an earthquake without compromising structural integrity or stability. 

Earthquake and seismic fastening systems are essential for protecting your Seattle home or business from potential damage caused by seismic activity. By staying informed about the latest technological advances, you can ensure that your home or business will be protected against even the strongest earthquakes imaginable!

How to Stay Safe During an Earthquake and Shut Off Your Gas Main

How to Stay Safe During an Earthquake and Shut Off Your Gas Main

Earthquakes are major natural disasters that can cause considerable damage if unprepared. It is important to understand the appropriate safety precautions for earthquake preparedness, especially for those living near Shoreline. These include creating an emergency kit and knowing how to shut off your earthquake and seismic gas shut-off valves.

Here are some tips on staying safe during an earthquake:

Creating an Emergency Kit 

The first step in preparing for an earthquake is having an emergency kit. This should include items like food, water, a flashlight with extra batteries, any necessary medications, a first aid kit, and other items that you may need in an emergency.

It’s also important to have copies of all essential documents like birth certificates, insurance policies, and other personal items in case they get damaged or lost due to the earthquake. Every household should have a designated safe place where everyone can go until the shaking stops. Once the shaking subsides, it is then safe to evacuate the area if needed. 

Shutting off Your Gas Main 

In addition to having an emergency kit ready, it is also necessary to know how to shut off your gas main in case of a natural disaster like an earthquake. Shutting off your gas main will depend on whether you have manual or automatic valves installed in your home or business. If you have manual valves installed (often referred to as “gate valves”), these must be turned by hand using either a flathead screwdriver or an adjustable wrench. 

To turn them off completely, turn the valve clockwise until it stops turning; this ensures that no more gas will flow into your home or business from the main line outside your property. If you have installed automatic valves (often called “ball valves”), they can be turned off remotely from inside your home or business by pressing a button or switch near the valve. 

Earthquakes can cause significant destruction if you are not adequately prepared beforehand. Taking steps such as creating an emergency kit and learning how to shut off your earthquake and seismic gas shut-off valves can help ensure that you stay safe during a disastrous event.

How Seismic Retrofitting Specialists Build Better Before the Next Disaster

How Seismic Retrofitting Specialists Build Better Before the Next Disaster

In light of recent events in Seattle, the importance of seismic retrofitting specialists has come into focus for most residents. Seismic retrofitting is the process of strengthening a building or structure to withstand an earthquake better.

This is done by assessing the vulnerability of the building and making changes to the foundation, framing, and/or walls to make the structure more stable and less likely to collapse.

Seismic retrofitting is an important consideration for any business or homeowner in an earthquake-prone area. Though the upfront cost of retrofitting can be significant, it is nothing compared to rebuilding after a disaster. 

In addition to the financial considerations, there is also a very real human cost to consider. A collapsed building can result in serious injuries or even loss of life. By retrofitting your building now, you can help protect your employees, customers, and family in the event of an earthquake.

How Seismic Retrofitting Is Done

There are several ways to retrofit a building, depending on the structure’s specific needs. The most common methods include the following:

    Foundation bolting: This involves attaching the home’s frame to its foundation with large bolts or steel plates. This helps to prevent the frame from shifting during an earthquake and collapsing. 

    Bracing cripple walls: Cripple walls are short walls that run along the perimeter of a home between the foundation and the first-floor framing. These walls can be strengthened by adding plywood or sheathing along their length. This helps to prevent them from buckling during an earthquake. 

    Adding sway bracing: Sway bracing helps to stabilize a building by connecting the roof rafters to the wall studs. This provides additional support that helps keep the building from swaying during an earthquake. 

    Reinforcing attic and garage doors: Attic and garage doors are often overlooked when it comes to seismic retrofitting, but they can be one of the weakest points in a building’s structure.

By reinforcing these doors with additional bracing, you can help prevent them from flying open during an earthquake and causing damage to the rest of the building.

We Love Our Customers!

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.


They did a wonderful job on the seismic retrofitting. Our 1926 house is noticeably more stable. The workers were very pleasant to have in our home, and they cleaned up shockingly well when they were done. If we could hire them for the rest of our home improvement job we would.


It’s a matter of time, experts say, before the Northwest shudders under another massive tectonic plate earthquake or the Puget Sound region succumbs to a big quake from one of its faults. Wood frame homes generally survive the earth shaking. But there’s a risk of them sliding off the foundation. Split-level homes also may crumble along the pony wall, sometimes called a cripple wall, that supports the upper level. Quake risks were not that well known when my home was built in Bothell in 1975. In the summer of 2022, Evergreen Seismic upgraded the house with a retrofit. This included installing anchor bolts and hold-downs into the foundation and bracing the walls in places with ¾-inch CDX plywood. Owner Matt Robinson and his crew worked in a tight crawlspace. They also removed some outside siding to brace the pony wall, upgrading the insulation before replacing the siding. Matt handled all the required engineering plans, permits and inspections. Matt showed he is skilled in retrofitting. He communicated clearly about scope of the work and scheduling. The site was cleaned after each day and neatly finished at the conclusion. The retrofit improved the safety of my home. I have documentation that I believe adds to its value. Of various people we’ve had in our home from time to time for repairs or remodeling, Matt Robinson is one of the best. I recommend Evergreen Seismic for its quality of work and service. Doug in Bothell


If you need to earthquake your home for seismic activity, then you can definitely trust these guys. Matt and his team at Evergreen Seismic are very knowledgeable and do a great job.


I loved Evergreen Seismic so much that I hardly know where to start this review. I got three bids to retrofit our 1962 home, which has a finished walkout basement and required structural engineering. All three companies were very professional and gave me comparable recommendations. Here’s why I’m so happy that I went with Matt: Quality and attention to detail: Notably, a respected competitor described Matt as “the best retrofitter I know.” During the bid process, Matt answered my extensive questions with sound, thorough information. On site, he was happy to show me the in-progress guts of the work, explaining the rationale and placement of all the hardware, additional framing, and shear panels. He also pointed out places where people sometimes cut corners and educated me on how to recognize correct, up-to-code work. Matt and Nick used high-quality materials, high-quality tools, and every element they added to our home was carefully and precisely placed. Their work passed all inspections without a hitch. Matt even paid thoughtful attention to aesthetic details, like staggering their cuts into our siding for a pleasing end result, and purchasing a color of caulk that would blend into our paint. In all matters of quality, Matt ran a tight ship. I feel safe and secure in our home, having witnessed his expertise and skill. Professionalism: Others have said it, and I’ll say it again: Matt is the consummate professional. He was easy to communicate with and responded quickly. He set clear expectations for any minor distress the siding of the house might incur during the project. He cheerfully dealt with tight spaces and a maddening tangle of defunct cables attached to the side of the house. He and Nick kept a tidy jobsite, cleaning up beautifully at the end of each day and truly leaving the interior cleaner than they found it at the end of the job. They appeared to even be packing out tiny pieces of trash like paper towels from washing their hands, rather than using the trash cans I placed out for them. Matt had to cut an old landline cable that we hadn’t planned to use, and he pointed it out right away and offered to pay to have it reconnected - a high-integrity move. Finally, he spoke very highly of his competitors without exception, which says a lot. Kindness and care: Matt is just a wonderful human to be around. He’s easygoing, straightforward, considerate, thoughtful, warm, and generous with his time. When I met Matt in the fall, I was experiencing a period of high anxiety, and I came to him with a long list of bothersome questions as I was deciding who to hire. Even though he was busy, he went far out of his way to write detailed answers, send me safety data sheets, and chat on the phone with me multiple times. Some of my questions and worries were probably ridiculous, but he treated them as if they were completely reasonable and even welcome. He never made me feel like an annoyance, and his willingness to meet me where I was at, with so much empathy and humanity, meant a lot. Oh - and he and Nick treated my five-year-old as a person worthy of as much attention and respect as an adult, which is rare! With all of that put together, we were so happy we went with Matt and honestly feel kind of bummed that we probably won’t ever get to hire him for anything else. A few final details: Matt’s bid was in the middle of the three we received, but it was within $40 of its closest neighbor, so basically identical. Contracts and payment were all quick and easy. And for anyone exercising extra caution during the pandemic, Evergreen Seismic was extremely covid-conscious. The team was fully-vaccinated and wore high-quality masks for the entire duration of the job. I don’t even know what their faces look like. Even though they were working outdoors in the fresh air with no one else around, they always had a mask around their neck to be pulled up within a moment’s notice when I popped over to greet them. A+!


Evergreen Seismic recently completed an earthquake retrofit on our home. We chose the company in part because of great online reviews and we were not disappointed. Matt clearly explained the entire process and patiently responded to all of our questions. The work went smoothly and efficiently, was completed ahead of schedule, and the daily cleanup was amazing. Most importantly (for us anyway), the person who sold us on the job (Matt) was also part of the working crew. I wholeheartedly recommend Evergreen Seismic for earthquake retrofitting. From start to finish, this was by far the smoothest construction job we have experienced during the twenty years that we have lived in our home.


We used Evergreen Seismic to do an earthquake retrofit on our 1979 build home in Kent, WA based upon great customer reviews. We were not disappointed! Matt and his crew were very professional and showed up as promised. We were promptly informed when on one occasion they were a bit late due to traffic congestion. The work was performed to our satisfaction. The daily cleanup was impeccable. Matt was able to answer all questions that the inspector asked to his satisfaction. The Company actually went over and above what the structural analysis indicated was needed (additional bracing was installed). The majority of the retrofit was done on the exterior of the house in pouring rain! However, to our amazement, this did not in any way slow down the crew! A truly professional Company. We can recommend Evergreen Seismic without any hesitation.
