    Foundation Repair Coos Bay

    Foundation issues can lead to significant damage to your home if they aren’t taken care of. Homeowners in Coos Bay, OR, may experience symptoms like cracks in the floors, bowing walls, and sagging floors, all of which could indicate more serious structural problems. You might notice doors sticking, windows that won’t close properly, or visible gaps between your walls and ceilings. These issues could be signs that your foundation is shifting due to soil movement, water damage, or the natural aging of your home.

    At TerraFirma, we specialize in foundation repair in Coos Bay, offering expert solutions that address the specific causes of your foundation issues. We start with a thorough inspection to evaluate the extent and source of the problem, followed by personalized recommendations for our reliable foundation repair systems.

    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 are great for areas with known soil conditions, while push piers work best in locations with uncertain stability. Both options are minimally invasive and provide lasting solutions for your foundation needs in Coos Bay.

    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 professional installation, ongoing maintenance options, and transferable warranties, giving you confidence and peace of mind in your home in Coos Bay.

    Basement Waterproofing Coos Bay

    A damp basement can create serious problems for your home in Coos Bay, such as mold, mildew, structural damage, and decreased air quality. You might notice signs of water intrusion like musty odors, discolored walls, pooling water, or efflorescence, which is a white, powdery residue left when water evaporates. Even a tiny crack in your basement wall can be a major route for moisture to enter.

    TerraFirma provides state-of-the-art basement waterproofing solutions in Coos Bay, ensuring your space stays dry, healthy, and functional—regardless of the weather.

    We design and install custom drainage systems in Coos Bay that effectively redirect 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 Coos Bay, OR not only safeguards your investment, but it also turns your basement into a safe and functional extension of your home.

    Crawl Space Repair Coos Bay

    Crawl spaces in Coos Bay are often forgotten, but they’re essential for your home’s integrity and air quality. If left unattended, a neglected crawl space can become a breeding ground for mold, pests, and standing water. These problems can lead to wood rot, unpleasant odors, and even health issues for you and your family.

    We understand the unique crawl space conditions in Coos Bay, OR, and TerraFirma’s crawl space repair services are tailored to tackle moisture, mold, pests, and sagging floors with comprehensive solutions like full encapsulation, drainage, and 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 Coos Bay

    Damaged, cracked, or uneven concrete isn’t just an eyesore—it can also pose safety risks. Issues like poor soil compaction, freeze-thaw cycles, erosion, and tree root growth can all contribute to these problems. That’s why homeowners in Coos Bay trust us to quickly and effectively repair their concrete slabs, sidewalks, patios, and driveways.

    At TerraFirma in Coos Bay, we provide quick, efficient, and durable concrete leveling and repair services using cutting-edge polyurethane foam injection and expert crack sealing.

    • Sidewalks – Eliminates tripping hazards and restores smooth walkways.

    • Patios, Porches, and Pool Decks – Ensures proper drainage and surface stability.

    Earthquake Retrofitting Coos Bay, OR

    Coos Bay, OR, is located in a region that’s known for its seismic activity. Homes constructed before the updated building codes of the 1990s are particularly at risk. Even a minor earthquake can lead to shifting off foundations or significant structural damage.

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

    Retrofitting your home for earthquakes in Coos Bay can help lower your insurance premiums and deductibles, plus you may qualify for coverage that wasn’t available before the upgrade.

    How We Retrofit

    Assessment & Planning

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

    This assessment looks at the foundation, walls, roof, and overall structure of your property. From there, our engineer will create a detailed retrofitting plan tailored to the findings.

    Foundation Bolting

    Securing the foundation is the next step in ensuring your home’s stability. Our skilled technicians will install anchor bolts to firmly connect your house to its foundation, providing protection against lateral movement during an earthquake—keeping your Coos Bay home safe and sound.

    This process involves drilling into the foundation and inserting steel bolts. Our team then tightens these bolts to reinforce the structure, improving its stability and resilience against seismic activity.

    Adding Shear Walls

    Shear walls play a vital role in earthquake retrofitting by helping to distribute seismic forces, ensuring that buildings in Coos Bay stay safe and secure during seismic events.

    Shear walls, made from strong materials like plywood, are strategically placed throughout homes, especially in areas known as cripple walls. This added support helps ensure your walls remain stable, reducing the risk of damage during an earthquake—a valuable consideration for homeowners in Coos Bay.

    Bracing & Reinforcing

    “Next, we enhance the vital areas of your Coos Bay home with sturdy steel braces and straps. Our team installs these reinforcements on key structural elements like the roof, walls, and floors. This crucial step boosts your home’s overall stability, ensuring it has the strength to withstand seismic forces.”

    Securing Applicances

    Ensuring that your appliances are secured can create a safer living environment for everyone in Coos Bay. It’s essential to anchor items like water heaters and refrigerators. Our technicians will also install protective measures for gas meters to help 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.

    Very nice very knowledgeable and the most efficient and quick job I've ever seen
    My wife and I recently bought a house and after removing carpet in the addition, we found fairly large cracks in the slab. Not sure of the severity we called terrafirma. They sent Dan out. Super cool dude and very informative. He was able to give us a solution to our problem. They were also able to fit us into their schedule quickly which was nice considering we had bare floors that needed to be finished. I would highly recommend terrafirma and co!
    We have had their water proofing system in our crawl space for 5 years and it has worked perfectly. They come out every year to check the system to make sure it is operating properly. It is with great pleasure working with Lucinda at their Roseburg office. And working with the service agent Jason. He is a real professional and checks everything on the system. We have great confidence in Jason and TerraFirma and highly recommend them for your water issue problems. They do it right the first time. Best, John Moeckel, Bend Oregon.
    TerraFirma was a pleasure to work with. There was a small hiccup in the job but they handled it timely and professionally. I highly recommend them for your foundation needs
    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!
    Great job. The two foremen were helpful and very good reps for the company.
    Mike, Steve and their crew from Terra Firma were outstanding. They were professional, on time and did some amazing work. I was very impressed with how they answered my questions and their quality of work. I would highly recommend Terra Firma for any of your foundation needs.
    So far, all looks good. It has only been a week since it was done. Hoping it stays this good 12 months from now and beyond. The crew was very professional.
    Everyone at TerraFirma has been great. From the initial bid to finishing the job, they are a top notch company with top notch people.
    Professional service from permitting to onsite work performance. Congenial personnel all around. Actual cost came in significantly under the initial bid after work start reevaluation. I’m very satisfied with the result of using push piers to stabilize the foundation and poly foam to further stabilize the floor and fill in gaps and voids. TerraFirma was quick and efficient and made a significant effort to work with my job schedule. I would use them again and won’t hesitate to recommend to others.
    Very happy with the entire process. Someone was available to give us a bid, complete the job, and follow-up in a timely and professional manner. Very impressed!
    We got to work with John and he was incredibly thorough, professional and handled everything perfectly. The crew that did the work were awesome. Very respectful and very helpful. Thank you, M. Tippey
