    Foundation Repair Tigard

    Foundation issues can lead to significant damage in your home if not taken care of. In Tigard, OR, you might observe symptoms like cracks in the floor, bowing walls, or sagging floors, all of which indicate potential structural problems. Homeowners here may also notice doors sticking, windows that won’t close correctly, or gaps appearing between walls and ceilings. These issues can signal that your foundation is shifting due to factors like soil movement, water damage, or wear and tear over time.

    At TerraFirma, we specialize in foundation repair right here in Tigard with precise, expert solutions designed to address the root cause of your foundation issues. Our process starts with a thorough inspection to evaluate the extent and source of the problem. After that, we’ll recommend one or more of our reliable foundation repair systems:

    Foundation piers

    Our push and helical piers are designed to stabilize and lift your foundation in Tigard by transferring its weight to deeper, more stable soil layers. Helical piers are perfect for areas with known soil conditions, while push piers are an excellent choice for locations with uncertain soil stability. Both systems are minimally invasive and provide long-lasting solutions for your foundation needs.

    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 Tigard home.

    Basement Waterproofing Tigard

    Having a wet basement in Tigard can result in mold, mildew, structural damage, and poor air quality throughout your home. You might notice signs of water intrusion like 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 open the door for moisture to seep in.

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

    We create custom drainage systems that effectively redirect water away from your basement and into sump pumps, helping to protect your foundation in Tigard, OR.

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

    Crawl Space Repair Tigard

    Crawl spaces in Tigard, OR, often go unnoticed, yet they play a vital role in your home’s structure and air quality. If left unmonitored, 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 Tigard, OR, and TerraFirma’s crawl space repair services are tailored to tackle moisture, mold, pests, and sagging floors with comprehensive 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.

    Hey Tigard,

    Your home survives – even thrives – on coffee and rain, just like you. And like you, it’s probably overdue for a checkup.

    Our simple 5-Step Structural Health Checklist will help you do a simple annual home checkup, and catch small problems before they become big ones. And we’ll show you what not to worry about!

    Earthquake Retrofitting Tigard, OR

    Much of the Pacific Northwest, including Tigard, is situated in an active seismic zone. Homes built before the updated building codes from the 1990s may be particularly at risk. Even a minor earthquake could cause your home to shift off its foundation or suffer significant structural damage.

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

    Enhancing your home with earthquake retrofitting in Tigard not only strengthens your property but can also lower your insurance premiums and deductibles, while making you eligible for coverage that wasn’t available before the upgrade.

    How We Retrofit

    Assessment & Planning

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

    This evaluation will look at the foundation, walls, roof, and overall structure of your home in Tigard. After that, our engineer will create a detailed retrofitting plan tailored to the findings.

    Foundation Bolting

    Securing the foundation is a crucial next step in the process. Our skilled technicians install anchor bolts to seamlessly connect your home to its foundation, ensuring stability and preventing any lateral movement during an earthquake.

    Our process includes carefully drilling into the foundation and inserting steel bolts. Our team then tightens these bolts to reinforce the structure, improving its stability and resistance to seismic activity right here in Tigard.

    Adding Shear Walls

    Shear walls play a vital role in earthquake retrofitting here in Tigard, OR, as they help distribute seismic forces, keeping buildings safe and preventing collapses.

    Shear walls, made from sturdy materials like plywood, are strategically placed in homes throughout Tigard, especially in areas known as cripple walls. These installations enhance the support and stability of your walls, helping to minimize the risk of damage during an earthquake.

    Bracing & Reinforcing

    Next, we enhance the strength of your Tigard home by adding steel braces and straps to vital areas. Our team secures these reinforcements to crucial structural components like the roof, walls, and floors. This step significantly boosts your home’s stability, providing a robust framework designed to withstand seismic activity.

    Securing Applicances

    By securing your appliances, you can create a safer home for you and your family in Tigard. It’s crucial to anchor items like water heaters and refrigerators. Our technicians are also here to install safety measures for gas meters, helping to minimize 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.

    The foreman was very detailed oriented, gave good consideration to the job, and was very easy to work with. The work done was excellent and the crew left the work site in better condition than what they started with.

    Schyler did a fantastic job. He answered all the questions while here, he was knowledgeable and efficient. It was a pleasure having him do the work. Ron
    Thank you Andrew K for doing an excellent job smoothing out our sidewalk. There were extra challenges because of tree roots but Andrew thoughtfully came up with effective solutions and minimal grinding. He was on time, efficient, and very helpful. A job well done!
    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!
    Fourth project completed by Terrafirma for our property and while not everything always goes according to plan, they make good and stand behind quality customer service. Today we had three amazing employees- Jorge, Juan, Alencio solve some tricky problems with a smile and positive attitude! So appreciate another solution!
    Andrew, Zach, and Brent arrived and completed the job on time. They worked with our old house’s existing flooring.
    Terra Firma is a wonderful company to work with. The scheduling and prompt arrival of the team to my house was exemplary. They were careful and knowledgeable and thorough with all of their work.
    Giovanni and his crew were very professional. They showed up on time both days and got the job done on schedule. Giovanni carefully reviewed with us the work to be done before starting. At the completion on the job he reviewed what they had done. Giovanni was great to work with. He was very personable and had excellent communication skills.
    Great company. They have done several projects over the years. Always good work ethic! Hard work! Cleaned up, put things back, all good
    My home is situated on a hillside that slopes south to north and east to west. My foundation stem walls along with my concrete floor were sinking and my floor was out of level. Terra Firma came and sunk several tubes down fifty-seven feet to stabalize my stem wall footings and they injected foam in several areas of my concrete floor to make it level again. They did a fantastic job and they were thourough and left my home in the same condition before they began the work. The only complaint I have is that the estimator indicated that many of the cracks in the concrete floor would close up with the foam and they did not.
