Salem Wet basements and Crawl Spaces Repaired

Throughout the year, rain showers in Salem
contribute to the lush landscapes and vibrant ecosystems that
define the Willamette Valley. This environment makes homes
particularly prone to moisture problems, commonly found in
basements and crawl spaces.

Foundation issues and earthquake risks in Salem

Nearby cities like Keizer and Corvallis also sit in an area
where soils can expand significantly (expansive soils) when they
absorb water and contract when they dry out. This cycle of
expansion and contraction can put pressure on foundations,
leading to cracks and structural damage over time.

Oregon is part of the seismically active Pacific Ring of Fire, and
earthquakes can occur throughout the state. This makes cities
as far as McMinnville and Bend also at risk. Making sure your
home is earthquake retrofitted and up to the current code will give
you the peace of mind to fully enjoy this region’s lush greenery
and vibrant ecosystems.

How do you Protect my home froM earthquake vulnerabilities?

TerraFirma has been protecting homes in Oregon and Washington preparation for seismic events for over 20 years. Here’s what we do:

Assessment & Planning

The retrofitting process begins with a detailed assessment of the building’s current condition. An expert, such as a structural engineer or trained technician, inspects the home to identify weaknesses and recommend appropriate solutions.

This evaluation includes examining the foundation, walls, roof, and overall framework. Then, the engineer develops a comprehensive retrofitting plan based on the findings.

Foundation Bolting

Securing the foundation is the next step in this process. Technicians install anchor bolts to connect the house to its foundation, preventing lateral movement during an earthquake.

This process involves drilling holes into the foundation and inserting steel bolts. The workers then tighten the bolts to secure the structure, enhancing its stability and resistance to seismic forces.

Adding Shear Walls

Shear walls are another critical component of earthquake retrofitting as they distribute seismic forces and prevent the structure from collapsing.

Shear walls typically consist of plywood or other strong materials, and workers install them in strategic locations throughout the home particularly in cripple walls. They provide the walls with additional support and stability, reducing the risk of failure during an earthquake.

Bracing & Reinforcing

Next comes bracing and reinforcing critical areas of the home with steel braces and straps. Workers install these to key structural elements such as the roof, walls, and floors. This step increases the home’s overall stability, so it has a tough framework that can withstand seismic forces.

Securing Applicances

Securing appliances will create a safer living environment for occupants. Anchoring items such as water heaters and refrigerators are essential. Technicians will also install protection for gas meters to limit the risk of gas leaks.

Reparing Foundations

During retrofitting, technicians may notice substantial foundation damage that needs immediate repair. Adding crawl space support posts and foundation piers, and stabilizing the walls are some of the ways TerraFirma can reinforce your foundation.

From Roseburg to Salem, Portland to Seattle, our Foundation Repair work speaks for itself

Skylar did an outstanding job. Very knowledgeable. Very pleased with the results. Joe Henslee
The crew that did the work were great and did a GREAT JOB.
Quinten, the service technician, did an amazing job of servicing the pumps and the dehumidifier, he thoroughly inspected the encapsulation system as well.
He is very knowledgeable about the whole system and answered my questions.
He gave some options for 'shipshape' warning system as well as 'Aspen Air 'purifier' both of which I intend to move forward with.
Your company is fortunate to have hired this quality of personnel.
I am equally satisfied with the original encapsulation crew.
Very good experience from day 1. They ended up not needing one of the permits or a window brace like originally planned, of which both items were credited back to me. The installation crew was professional, efficient, and more than tolerant explaining all the little details of what they were doing while I watched the process. I really like that they live streamed their engineers the entire time for QC, and even had a third party review inspection. I chose TerraFirma over 3 other companies for the warranty terms and for them being a long established Oregon local business, and I am very happy with their work and crew. I hope to not have any future structural repairs done but if I do, I will 1000% hire them again. Thanks!
The estimator, Tyler, and the applicator, Skyler, were very knowledgeable, efficient and friendly. Both explained what they were doing and how the process would help our deterioration under our garage floor. The process leveled out our garage floor. I believe it will also help stop the cracks that have increased in size over the years. I believe this process works!
A fantastic company,staff and did excellent job on my house.
Andrew and his crew completed our work project installing a sump pump, installed drain tile inside the crawl space under the house and finished with a vapor barrier. In addition they also removed all junk under the house. The crew was very efficient, the work space was kept very clean, when they were through you would hardly know they were there. They were very helpful and answered any questions we had and explained what was going on. We highly recommend this crew.
Travis and the crew did an excellent job with our crawlspace project. They were always on time even though they were coming from Roseburg to Bend, and great with giving updates as they went. We love our new crawlspace now and grateful for cleaner air, better temperature regulation in the home as well as the added benefit of extra storage. Thanks TerraFirma!
The crew did a great job fixing our sinking foundation! Two days and they came in and dug everything up then set the anchors and then backfilled! Great Job!
Excellent! Schyler was here right on time. He was friendly, courteous, cleaned up the work area well. Explained things and even helped me move my table back. Highly recommend.

I'd been putting off fixing our sunken garage for a few years. With the flooding seasons getting more and more distinct, it was time. i called a few...
Matthew was very professional my wife and I felt comfortable with his professional approach to our needs . I would recommend this company to those in need.
Thanks
Terra Firma has done a very nice job! The work was professionally completed. They were thorough and communicative. They walked me through all the details as they went and cleaned up well when they were completed. Very nice work!
I am very pleased with Terra Firma! I have gotten a quote and I'm pleased with what they quoted me. They were on time and very professional.
Once the job is...
Jaden came out and reassured us that our foundation was good but our garage floor is settling.
We look forward to working with Jaden and Terrafirma in early summer to fix the problem.(Too difficult to move everything off garage floor this time of year)
Thanks again Jaden for your professionalism.
Just had our annual inspection/maintenance check on our sump system, and the tech Steve-o did a great job. Unlike the tech the previous year, who barely even glanced at the system before charging $180 bucks for the service, Steve-o inspected every part of the system, removing and doing a full inspection/cleaning of each pump. He gave us thorough explanations of what he was doing and any issues he found, and gave us several options for continued maintenance going forward. Huge improvement over the previous year.

Update (12/17/2025): During this morning's crazy wind storm we lost power at 2am, and unfortunately our battery backup sump pump was at the end of its life and the motor died. We scrambled to get our generator running in time to avoid disaster, but in the meantime we were without a battery backup with more storms on the way this week and holiday travel where we were planning to be away.

I left an urgent message at probably 3am for TerraFirma, and got a call back from Lucinda at maybe 7:30. She managed to find a tech to come out this afternoon, who apparently came up from Roseburg to help with today's issues. The tech Jason was able to get a new backup, a new battery, and new controller box. Huge peace of mind for the coming weeks.

No one loves an unexpected bill before the holidays, but I'm grateful to Lucinda for making it happen and Jason for getting the work done quickly for us. TerraFirma continues to do us solid. Thanks!
I live in a home that was built in 1968. The slabs that made up my back patio were dangerously uneven. The side walkway was another roller coaster! Terra Firma’s workman, Dorian, did a wonderful job! The patio and sidewalk were both leveled and sanded to make it safe for everyone to walk on without tripping hazards. I have been really impressed by the employees of TF whom I have met – Matt and Dorian. They were so helpful and explained what to expect – what could and couldn’t be done and they lived up to their promises. They left my patio and walkway, spotless and safe to use. Thank you!
Schylar Powers showed up to fix our garage floor and was very professional the whole while he was working. He explained to us what he was going to do and showed us step by step as he went along. It is beautiful and we really appreciate the service. Thank you.
My mother-in-law’s house was built in 1962 and has had basement water issues for more than 40 years. We’ve spent so much money trying to fix it over the years, but TerraFirma Foundation Systems completely transformed the situation—it feels like magic.

Thank you to the team: Casey from sales and the crew members Antonio, Jessi, and Casey. The three musketeers worked efficiently and truly operated as a team. Thank you for bringing such an incredible change to my mother-in-law’s home!

One suggestion for management: please focus on bringing happiness to your customers rather than worrying too much about potential lawsuits.
This is our 2nd time to use Terra Firma and we can't recommend them highly enough. They had lifted our sunken front porch and driveway a few years ago. So,...
