Foundation Repair Specialists

foundation repair SOLUTIONS

Cracked foundations, nasty crawl spaces, and musty basements can be a nuisance for homeowners. The foundation repair specialists at TerraFirma can repair the structural integrity of homes. Our expertise focuses on identifying and resolving various issues caused by shifting soil, water intrusion, or age-related wear. We’ll come to your property, diagnose the problem, and start a repair plan to get your house back in shape.

There are several tactics that our foundation repair specialists will implement based on the assessment and analysis of the foundation. These may include the following:

  • Foundation anchors for extra support
  • Wall stabilization to prevent bowing or leaning walls
  • Vapor barriers to manage humidity levels and impede water damage

We offer free, on-site estimates to assess the damage and offer reliable solutions to stabilize homes in Portland, Seattle, Tacoma, Roseburg, and across the Pacific Northwest.

  • Extends to greater depths than alternative options
  • When soil conditions are unknown, push piers are the preferred solution because they are driven all the way to bedrock or a stable soil layer

Ask us about your pre-construction permanent foundation solutions for challenging builds. Excellent in both residential and commercial installations.

Grouted Micropile Tiebacks

TerraFima’s grouted MicroPile piers are typically used when challenging conditions-such as steep slopes, deep sand, rocky or wet soil, or complex geology-impede the function of other foundation piers.

Foundation Wall Stabilization

Cracks in your basement or foundation walls are a sign of foundation stress. Stabilization of foundation walls helps repair or prevent cracking or bowing walls.

Proactively addressing these problems with our foundation stabilization methods ensures the long-term stability of your home and prevents costly repairs down the line. Each foundation wall repair solution is tailored to meet the specific needs of your home, providing peace of mind for you and your family.

Crawl Space Support Posts

When floors in the home start to sag, this may not be a foundation issue but a possible problem in the crawl space underneath. Homeowners in Oregon and Washington are very familiar with the damage our wet, damp, and expanding soils do to our homes. If left unchecked, these conditions can lead to wood rot, mold growth, and pest infestations, further weakening the structural integrity of the crawl space. Poor ventilation and trapped moisture exacerbate these issues, creating an unhealthy environment that can impact indoor air quality. Proactively addressing these problems with crawl space support posts not only protects your home but also ensures a safer, more comfortable living space.

REVIEWS

Don’t take our word for it – see what our clients have to say.
From Roseburg to Eugene, Portland to Seattle, our Foundation Repair work speaks for itself

I don’t usually do reviews but in this case people should know this is a first class company. Great communications and no selling you on something you don’t need. John was very professional, he spent time with us expanding what issues he did find, measured the level of the floors, inspected under the house and checked wall and foundation cracks. He also placed a blanket down to collect any dirt from entering and exiting the crawl space inside the house. I highly recommend John from the Eugene office and TerraFirma.
We had two companies come and provide evaluations of our foundation repair needs. TerraFirma was by far the most professional and responsive company. In the end we did not go with the lowest bid but we did go with the company that provided the most professional response and gave use the most confidence it would be done right. We were not disappointed 😊
I cannot express enough how grateful I am for the exceptional service provided by Seth and the team at TerraFirma Foundation Systems. We were facing a daunting challenge with standing water underneath our house, and Seth guided us through the entire process with professionalism, expertise, and genuine kindness. From the moment Seth arrived, it was evident that he was not only knowledgeable but also deeply passionate about resolving our issue. His expertise in dealing with water problems beneath homes was evident, and he took the time to thoroughly assess our situation (and got plenty dirty doing it) before presenting us with a comprehensive solution. He patiently answered all of our questions, alleviating any concerns we had along the way. It was clear that he genuinely cared about finding the best possible outcome for us. Consider this company, it'll be worth your time!
Hey Folks, So just over a year ago we were having some issues at the house, I wrote to all of you on how wonderful TerraFirma was to us and I am here to tell you... THEY DID IT AGAIN! I starting noticing some movement in the driveway and inside the garage again. Called up Bree in the office and asked to have someone come take a peek. Edwin came out, what an awesome dude! Edwin spent a short time at the house remeasuring a couple things to compare back at the office with measurements from a few months ago, We heard from Bree that the measurements were still within reason. I let Bree know, something is not sitting well with me and I really would like to chat with the Mgr. So I received a call from Tulane, Again SUPER DUDE! Tulane assured me with my husband present that I am not being in any sorts a pain, I have concerns and he and Sam, who came out in 2024 will come to the house. Well they came, they saw, Oh Boy! I was not wrong, they were here 2.5 hrs and again, the house has had some movement and we need some more work to stabilize. We have some additional C.Y.A's to add to this round, as our neighborhood and home has lots of sand in the soil so we are going to be looking into getting a GEO Engineer out to see what is causing the movement. I give all the back info, because I want you all to know, if you feel something is not right CALL and have your home looked at. TerraFirma is NOT redoing what they already did, this is all new issues, not their fault at all... Tulane and Sam are amazing, they took the time to explain and give us all options. The info they share through experience and knowledge is beyond me and it is so appreciated. If you have any foundation, sinking driveways, walkways, stairs, cracking in your walls, around windows, doors.... Call these guys! I hands down don't always do reviews but I do for these guys because they deserve to have their names out there so you know they are TAKING CARE of their customers the whole way through! 10/10 and then some.... THANK YOU!
Update: Robert and Jacob showed up and fixed my sagging kitchen floor. Punctual, professional, thorough, fast! Highly recommend TerraFirma to anyone needing foundation services. Overall total experience was top notch!! Thank you TF!! Noah arrived punctually and impressed from the get-go! He was here for an estimate visit and began with the explanation of how the appointment would be performed He was very thorough in explaining every detail and options available to me. Although I have not committed, Noah’s professionalism and knowledge were on point and I am definitely going to consider using Terra Firma for my sagging kitchen floor. Stay tuned…
Crew did very fine job stabilizing sinking corner part of my house thanks to Mike and his colleagues.
Adam was here today doing our annual maintenance and inspection. Over the years that we’ve had inspections, Adam did by far the best ever. He did work that no others did, and fix things that needed fixing but never were before. Like the dehumidifier was moved to a much better location. And he cleaned out an area that had a round plastic container sunk deep into the ground that was full of dead mice. He foamed another area in the cement foundation where bugs were getting in. He did a very thorough job that I’m sure will make a big difference in what we call our “White Cave.” We were favorable impressed and ask that he does our annual inspection each year.
I reached out to TerraFirma Foundation Systems to have them come look at my foundation. They were able to get me on the schedule within the week. Seth showed up on time for the appointment and got right to business. He walked me through what he was going to do and what he was looking for. He was very professional and polite. He even took his shoes off outside everytime he had to come in the house. Which is a big deal to me. When he finished the inspection we sat down and went over all my options. The whole experience was easy and I didn't feel taken. I would highly recommend Seth and TerraFirma.
Seth came out to evaluate my foundation and gave me one of the most thorough and honest assessments I've experienced from a contractor. Professional, communicative, and zero pressure — he clearly takes pride in his work. I didn't move forward with the project through Terra Firma, but that has nothing to do with Seth or the quality of his visit. Highly recommend requesting him specifically. 5 stars.
What is can say to home owners is if you see a problem Don't Wait! Call Terra Firma now! The evaluation is free. Walt explained everything that was the cause and what options are available for fixing and managing budget constraints. I will be much safer having the problem addressed and if I had waited things would have been much worse and more expensive. Thank you Terra Firma you saved my home again!
I met with Walt Bateman this week to discuss an issue I have that sounded like TerraFirma was a good place to look for a professional opinion. Walt shared his expertise and extensive knowledge of about 30 years of experience in the Eugene / Springfield area regarding geotechnical and residential construction issues and solutions to foundation and concrete structural issues in our wet environment. We discussed a variety of potential alternatives and he left me a relatively easy and cost effective solution for my project. I was very pleased to meet Walt and happy with his response just one day after contacting TerraFirma. I highly recommend Walt as an honest straight shooting guy and happy to get his opinion for my project. Thanks to Walt and TerraFirma, Steve Z, Springfield, OR.
Work well done and coordinated with HVAC company. Started and ended as promised. Courteous workers who explained what they were doing. Only glitch was that when boring through concrete foundation for sump pump drain, the comcast cable was damaged.
