    Foundation Repair Hammond

    Foundation issues can lead to significant damage in your home if not taken care of. Homeowners in Hammond, OR may notice signs like cracks in the floors, bowing walls, or sagging floors, all of which can point to deeper structural concerns. You might find that doors start to stick, windows refuse to close correctly, or gaps appear between the walls and ceilings. These issues can indicate that your foundation is shifting due to soil movement, water damage, or the natural aging process.

    At TerraFirma, we specialize in foundation repairs in Hammond, offering targeted, expert solutions designed to address the root causes of your foundation issues. Our process starts with a thorough inspection to determine the extent and source of the problem. From there, we recommend one or more of our trusted foundation repair systems:

    Foundation piers

    Our push and helical piers are designed to stabilize and lift your foundation by shifting its weight to deeper, more stable soil. Helical piers work best in areas with known soil conditions, while push piers are ideal for locations where soil stability is uncertain. Both solutions are minimally invasive and provide lasting support for your home in Hammond.

    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, flexible maintenance options, and transferable warranties, so you can feel confident and at ease in your Hammond home.

    Basement Waterproofing Hammond

    Experiencing a wet basement in Hammond can lead to mold, mildew, structural issues, and poor air quality in your home. You might notice signs of water intrusion such as musty odors, stained walls, standing water, or efflorescence—a white, powdery residue that appears when water evaporates. Even a tiny crack in your basement wall can turn into a significant gateway for moisture.

    TerraFirma provides top-notch basement waterproofing solutions in Hammond, ensuring your space stays dry, healthy, and functional no matter the weather.

    We install custom drainage systems in Hammond, OR, designed to redirect water away from your basement and into sump pumps, helping to protect 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 Hammond, OR not only safeguards your investment but also turns your basement into a safe and functional extension of your home.

    Crawl Space Repair Hammond

    Crawl spaces in Hammond are often forgotten, but they play a vital role in your home’s structure and air quality. If left unattended, a neglected crawl space can become a breeding ground for mold, pests, and standing water. These issues can lead to wood rot, unpleasant odors, and even respiratory problems for you and your family.

    We understand the unique crawl space conditions in Hammond, OR, and TerraFirma’s repair services are tailored to tackle moisture, mold, pests, and sagging floors with complete encapsulation, effective drainage solutions, 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.

    Concrete Repair Hammond

    Damaged, cracked, or uneven concrete isn’t just an eyesore—it’s a safety risk as well.

    TerraFirma provides quick, reliable, and durable concrete leveling and repair services in Hammond, OR, using cutting-edge polyurethane foam injection and effective crack sealing.

    Earthquake Retrofitting Hammond, OR

    Hammond, OR, sits in an active seismic zone of the Pacific Northwest. Homes constructed before the updated building codes of the 1990s may be particularly at risk. Even a minor earthquake could cause a home to shift from its foundation or sustain significant structural damage.

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

    Upgrading your home with earthquake retrofitting in Hammond not only strengthens your property but can also help lower your insurance premiums and deductibles, plus you might qualify for coverage options that weren’t available before.

    How We Retrofit

    Assessment & Planning

    In Hammond, OR, the retrofitting process kicks off with a thorough assessment of your building’s current condition. A qualified expert, like a structural engineer or skilled technician, will inspect your home to pinpoint any weaknesses and suggest the best solutions.

    This assessment covers the foundation, walls, roof, and overall structure of your home. Following the evaluation, our engineer will create a detailed retrofitting plan tailored to the specific findings.

    Foundation Bolting

    Securing the foundation is the next important step for homes in Hammond, OR. Our technicians install anchor bolts to firmly connect your house to its foundation, helping to prevent any lateral movement during an earthquake.

    Our process begins by drilling holes into the foundation and inserting sturdy steel bolts. Our team then tightens the bolts to ensure the structure is secure, boosting its stability and resilience against seismic activity.

    Adding Shear Walls

    Shear walls play a vital role in earthquake retrofitting here in Hammond, OR, as they help distribute seismic forces and keep buildings from collapsing.

    Shear walls are usually made from plywood or other sturdy materials, and are strategically installed throughout homes, especially in cripple walls. They enhance the support and stability of your walls, helping to reduce the risk of damage during an earthquake—a crucial consideration for homeowners in Hammond, OR.

    Bracing & Reinforcing

    Next, we fortify key areas of your Hammond home with steel braces and straps. Our team installs these on vital structural elements like the roof, walls, and floors. This crucial step enhances your home’s stability, providing a robust framework designed to withstand seismic activity.

    Securing Applicances

    By securing your appliances, you can help create a safer home for everyone in Hammond. It’s important to anchor items like water heaters and refrigerators, and our technicians can also install protection for gas meters to reduce the risk of 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.

    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...
    Everyone, from the job estimator and office staff to that guys that repaired my foundation/driveway and installed the earthquake mitigation system, were very professional and courteous. Very happy with the final result!
    Jaden was prompt, professional and courteous. I would recommend him to anyone who requires his services.
    The crew showed up right as scheduled. The foundation work itself was completed in two days. Inspection and clean up occurred on the morning of the third day. I highly recommend Terra Firma.

    The company did good work. This is the second time we have used these services. Price has almost doubled in five years. Getting expensive!
    Edit: Jan ‘26 Unfortunately this sump pump did not solve the problem after all, as water again came in after several days of hard rain. To be fair, TF did not guarantee a solution. I still think it is a good company but sadly my problem persists. Previous review from Nov 25 - Terra Firma installed a sump pump in my home that has solved my water incursion issues. This had been a problem for months. I had several different companies and professionals out to evaluate and try to solve the problem, from plumbers to leak detection companies and a few more. Most scratched their heads and said "this is a mystery." Terra Firma came up with this solution and it is working. I wanted to wait until we had significant rain to write this review - and after the past few days of pretty good rain, and no water coming in - I feel confident that the problem was solved. They were helpful, considerate and creative. They didn't try to sell me more than was needed. I recommend Terra Firma.
    We had a complete encapsulation of our crawl space and sump pump and humidifier system installed. The young men who did the work were very professional. Antonio was the project manager and he was fantastic. Answered questions, explained the process, and made sure we were ok with what they were doing. They showed up at the time designated and called if they would be late. Communication was very good. Shout out to his helpers, Daniel, Jesse, and Kameron. At the end of the project they cleaned up the workspace and made sure things were left like it was before project. Thanks guys.
    Five Star to the Aris's team who worked on site! My project was stuck and the boys drive all the way from Vancouver up to Seattle to rescue. When I met them for the first time, I was deeply worried because those boys look so young! However, I was quickly impressed because the young boys really rock! They are super friendly and polite, they are energized and work so hard, I can tell they are proud of their craftsmanship and really care about your property. Kudos to Brad, Aris, Jose and Rudy! For the overall experience, there was a huge gap between sales team and production team, be prepared that you may not get any material/product like what the sales person showed to you, I did a lot of research on their product and that was the main reason I selected them, however, I did not get any of the product with specification that were promised, so this is quite disappointing - but I understand this is not really sales or field technician's fault...
    We had a really great experience with TerraFirma Foundation Systems from start to finish. Danny was our first point of contact and handled our bid, and he set the tone right away - knowledgeable, straightforward, and easy to talk to. From there, everything stayed consistent. Jorge Valencia led the crew with professionalism and clear communication along with Juan B. and Alencio who all did excellent work on site. You could tell this was a team that knew what they were doing and took pride in it. It was incredibly muddy under our house, and not an easy job by any stretch, but the crew didn’t complain once. They just got in there and got it done. What really impressed me was that when they finished, there wasn’t a single speck of mud left behind. That level of care and respect for someone’s home says a lot. The work itself was done efficiently and with attention to detail, and they kept us informed throughout the process. No surprises, no confusion, just solid, reliable work. What stood out the most, though, was something more personal. I have a young son with Down syndrome who is very curious. I was honestly worried he might be in the way, but the crew handled it in such a thoughtful, human way. They took the time to acknowledge him, talk with him, and make him feel included. It was incredibly heartwarming. He felt seen and heard, and that meant a lot to us. It’s rare to find a company that delivers both high-quality work and genuine kindness, but this team did both. I would absolutely recommend TerraFirma.
