    Foundation Repair Oak Grove

    Foundation issues can lead to significant damage if not taken care of. In Oak Grove, OR, homeowners might notice symptoms like cracks in the floors, bowing walls, or sagging floors, all of which could indicate more serious structural problems. You may find that doors don’t close properly, windows stick, or gaps appear between walls and ceilings. These signs often suggest that your foundation may be shifting due to soil movement, water damage, or simply the wear and tear of time.

    At TerraFirma, we provide expert foundation repair services in Oak Grove, addressing the specific issues affecting your home. Our process starts with a thorough inspection to identify the root cause of your foundation troubles. Based on our findings, we’ll recommend one or more of our trusted repair solutions tailored just for you:

    Foundation piers

    Our push and helical piers are designed to stabilize and lift your foundation by transferring its weight to deeper, more stable soil. Helical piers work best in areas with known soil conditions, while push piers are ideal for locations with uncertain soil stability. Both systems are minimally invasive and provide lasting solutions for your foundation needs in Oak Grove.

    Wall Stabilization Systems

    For cracked, bowing, or leaning walls, we offer a suite of reinforcement products. These include:

    • CarbonArmor®: Made from fiber-reinforced polymers ten times stronger than steel.
    • PowerBrace®: Zinc-plated steel beams that can be tightened over time.
    • GeoLock® Anchors and Helical Tiebacks: These systems halt inward movement and gradually straighten walls over time.
    • EverBrace™: Designed for severely deteriorated walls, this system replaces and reinforces failing foundation walls with steel supports.

    We also offer grouted micropile tiebacks for difficult soil conditions, SmartJack® crawl space support posts for sagging floors, and vapor barriers to manage humidity and prevent further moisture damage.

    Every solution comes with expert installation, ongoing maintenance options, and transferable warranties, ensuring you have confidence and peace of mind in your Oak Grove home.

    Basement Waterproofing Oak Grove

    Living in Oak Grove, OR, you know that a damp basement can cause serious issues like mold, mildew, structural damage, and poor air quality in your home. You might notice signs of water intrusion, such as musty odors, stained walls, pooling water, or efflorescence—a white, powdery residue that appears when water evaporates. Even a tiny crack in your basement wall can become a major pathway for moisture. Don’t let a small problem turn into a big headache!

    TerraFirma brings state-of-the-art basement waterproofing solutions to Oak Grove, ensuring your space stays dry, healthy, and fully functional—regardless of the weather.

    We create tailored drainage systems in Oak Grove that channel water away from your basement and into sump pumps, safeguarding your foundation.

    WaterGuard®: Our most popular system, it’s installed below the floor slab and above the footing to prevent clogging.
    DryTrak®: Ideal for monolithic foundations where jackhammering is not feasible.
    FlowGuard®: A thin-floor drain system used in basements with thin concrete slabs.
    TrenchLock™ Inserts: Block ground air from entering while allowing water to drain.

    We offer several sump pump options tailored to your water exposure:

    TripleSafe™: Three-pump system for maximum protection, including battery backup for power outages.
    UltraSump®: High-capacity battery backup pump that activates when the main pump fails or power goes out.
    SuperSump®: A single-pump system for homes with minor water issues.

    VaporLoc Elite: A heavy-duty wall liner that stops moisture and mold while directing water into drainage systems.
    SaniDry Sedona & XP: Energy-efficient dehumidifiers that remove up to 109 pints of moisture daily, improving air quality and comfort.

    Our SunHouse™ Window Wells and WellDuct® Drains keep your basement bright, dry, and free from debris, while meeting egress codes for safety.

    Waterproofing in Oak Grove, OR not only safeguards your investment but also turns your basement into a safe and functional extension of your home.

    Crawl Space Repair Oak Grove

    Many homeowners in Oak Grove, OR, tend to overlook their crawl spaces, but these areas play a vital role in your home’s structure and air quality.

These issues can lead to wood rot, unpleasant odors, and even respiratory problems for your family.

    We understand the unique crawl space conditions in Oak Grove, OR, and TerraFirma’s repair services are specifically designed to tackle moisture, mold, pests, and sagging floors. Our comprehensive solutions include full encapsulation, effective drainage, and robust structural support.

    Encapsulation & Drainage

    We begin by sealing the crawl space with our VaporLoc Elite liner, a 120-mil thick waterproof barrier that blocks moisture, soil gases, and allergens. To ensure proper drainage:

    • We use drainage matting under the liner to guide water to your perimeter drain or sump pump.
    • Sump pumps remove water quickly and efficiently, even during heavy rain or high water table conditions.

    Earthquake Retrofitting Oak Grove, OR

    Oak Grove, OR, is located in an area of the Pacific Northwest known for its seismic activity. Homes constructed before the updated building codes of the 1990s may be particularly at risk. Even a small earthquake can lead to significant issues, causing a house to shift off its foundation or suffer major structural damage.

    TerraFirma’s earthquake retrofitting services help secure your Oak Grove home to its foundation and strengthen its ability to withstand seismic events.

    Retrofitting your home for earthquakes in Oak Grove not only helps protect your property but can also lower your insurance premiums and deductibles, and may even make you eligible for coverage options that weren’t available before.

    How We Retrofit

    Assessment & Planning

    In Oak Grove, OR, the retrofitting process starts with a thorough evaluation of your building’s current condition. Our skilled experts, including structural engineers and trained technicians, will assess your home to pinpoint any weaknesses and suggest the best solutions.

    This evaluation involves checking the foundation, walls, roof, and overall structure. After that, our engineer creates a detailed retrofitting plan tailored to the findings.

    Foundation Bolting

    Strengthening the foundation is the next step in the process. Our technicians install anchor bolts to securely connect your home to its foundation, helping to prevent any shifting during an earthquake here in Oak Grove.

    In Oak Grove, our process includes drilling into the foundation and securely installing steel bolts. Our skilled workers then tighten these bolts, strengthening the structure and boosting its stability against seismic activity.

    Adding Shear Walls

    Shear walls are essential for earthquake retrofitting in Oak Grove, as they help distribute seismic forces, keeping your home safe from collapse.

    Shear walls in Oak Grove are usually made of sturdy materials like plywood. Our experienced workers expertly install them in key spots around your home, especially in cripple walls. This extra support boosts the stability of your walls and helps minimize the risk of damage during an earthquake.

    Bracing & Reinforcing

    Next, we fortify vital areas of your Oak Grove home with durable steel braces and straps. Our team installs these reinforcements on essential structural components like the roof, walls, and floors. This crucial step enhances your home’s stability, ensuring it has a robust framework ready to withstand any seismic forces.

    Securing Applicances

    By securing your appliances, you can create a safer living environment for everyone in Oak Grove. It’s important to anchor items like water heaters and refrigerators. Our technicians will also install protective measures for gas meters, helping to reduce 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.

    We spent $25,000 to have under our house encapsulated. The mice keep getting in, they came out one time and found a spot that wasn't sealed and said they...
    The guys that came Jorge, Juan, Manuel, Luis, Wesley, Miguel to do the trenching and sump pump install were amazing. Very courteous and hard working. They went over and above to keep things clean and finished the job in a timely matter. Don the sales guy was great as well.
    Giovanny and his team (Diego and Arturo) really did an amazing job! They explained carefully what they were going to do, answering all my questions. The quality of work was first-rate. When they were finished everything was cleaned up to the extent that you couldn’t even tell they were here.
    We have a daylight ranch that was built in the mid 20th century. It became apparent that the patches prior owners had done were not cutting it to mitigate the water problem in our space. After consulting with a number of companies, we found Terra Firma's solution was the only version we felt confident would actually solve the problem. Everyone we interacted with from their sales team to their on-site crew were personable, respectful, and worked with us on every step to confirm we were comfortable with the plan, and changes that came up along the way. They finished their work on time, kept the space clean at the end of each day (a 4 day project), not just at the end of the project. We were impressed with their diligence and support throughout the project. I highly recommend them!
    Great customer service. Worked through complicated scope change.
    This company is the gold standard for those interested in maintaining the health of their home. I tell you, ‘My home will never be the same’: The garage is level; We are earthquake proof; And, the will no longer be mold or mildew in my crawl space.
    The best part was, not just the satisfying outcome of the work done, but meeting & working with Walter. He talked to me so that I understood why parts of my home were on a downhill slope to disrepair. He drew illustrations so I could visualize each point he made: He was upfront & honest in his assessment of my 1972 home built in clay. If Terra Firma is the gold standard- Walter sure is the diamond. Get your free evaluation today & don’t forget to ask for Walt.
    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!
    Their rep came out and gave me an estimate for 2 projects. Elected to only do one. They showed up as scheduled... on a Sunday, no less. Completed the job. Looks great!
    We discovered water in our basement this past April and first called the competitor who had installed a waterproofing system back in 2015 for the previous owners. Unfortunately, their visit wasn’t very helpful -- they didn’t offer a clear solution or give us much confidence that they even wanted to do any work on our 115-year-old house. That’s when we reached out to TerraFirma for a second opinion, and it was the best decision we could have made.

    From the very beginning, Jaden, our System Design Specialist, was outstanding. He was thorough, thoughtful, and really listened to our concerns. He walked us through options, answered all our questions, and came up with a solution that felt right for our home. Scheduling with Sammy was easy and helpful - she worked around our vacation schedule, and we always knew what was happening and when.

    When it came time for the work, Rocky and his team did an excellent job installing our new egress window, while Jorge, Juan, and Scott rebuilt our failed irrigation system from the under-ground up. Both teams were incredibly professional: always on time, tidy, communicative, and respectful of our neighbors (no small feat on our tight street with all the equipment and materials). Rocky went above & beyond with the window - making adjustments to the position and reinforcing our load bearing areas, and Jorge offered alternative and better solutions for our new sump-pump location that would ensure the functionality of our new system for decades to come.

    Every step of the process with TerraFirma exceeded our expectations. We honestly wish we had found them sooner for all our home projects. They turned what started as a stressful basement issue turned into a smooth and positive experience. Highly recommend! Thank you all for your help - we're so happy with how everything turned out!
    Fernando and his crew did an amazing job. They were very mindful of cleaning up after themselves, and Fernando explained and demonstrated everything so I could understand.
