    Foundation Repair Damascus

    Foundation issues can lead to significant damage to your home if not taken care of. Common signs to watch for include cracks in the floors, bowing walls, and sagging floors, which often indicate deeper structural concerns. Homeowners in Damascus, OR may notice doors that stick, windows that are difficult to close, or gaps appearing between the walls and ceilings. These issues might suggest that your foundation is shifting due to soil movement, water damage, or simply age.

    At TerraFirma, we specialize in foundation repairs in Damascus, offering expert solutions designed specifically for the unique issues affecting your home. Our process starts with a thorough inspection to identify the root cause and extent of your foundation concerns. From there, we’ll recommend one or more of our trusted foundation repair systems:

    Foundation piers

    Our push and helical piers are designed to stabilize and elevate your foundation by shifting its weight to deeper, more stable soil. Helical piers work best in areas with predictable soil conditions, while push piers are great for locations where soil stability is less certain. Both options are minimally invasive and provide lasting solutions for your foundation needs in Damascus.

    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, convenient maintenance options, and transferable warranties, ensuring you feel confident and at ease in your Damascus home.

    Basement Waterproofing Damascus

    Dealing with a wet basement in Damascus, OR? It can lead to mold, mildew, structural issues, and poor air quality in your home. You might notice musty odors, stained walls, puddles of water, or a white, powdery substance called efflorescence that appears as water evaporates. Remember, even a tiny crack in your basement wall can turn into a significant gateway for moisture.

    TerraFirma provides top-notch basement waterproofing solutions in Damascus to ensure your space stays dry, healthy, and functional—regardless of the weather.

    In Damascus, OR, we design and install custom drainage systems that efficiently channel water away from your basement and into sump pumps, ensuring your foundation stays protected.

    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.

    Concrete Repair Damascus

    Damaged, cracked, or uneven concrete isn’t just an eyesore—it’s a safety risk. These issues can arise from poor soil compaction, freeze-thaw cycles, erosion, or tree roots. Residents of Damascus trust us to swiftly and effectively repair their concrete slabs, sidewalks, patios, and driveways.

    Earthquake Retrofitting Damascus, OR

    Much of the Pacific Northwest, including Damascus, OR, is located in an active seismic zone. Homes built before the updated building codes from the 1990s are particularly at risk. Even a minor earthquake can lead to damage that shifts a home off its foundation or causes significant structural issues.

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

    Upgrading your home with earthquake retrofitting in Damascus not only enhances safety but can also lower your insurance premiums and deductibles. Plus, you might qualify for coverage options that weren’t available before the upgrade!

    How We Retrofit

    Assessment & Planning

    The retrofitting process starts with a thorough evaluation of your building’s current condition. A qualified expert, like a structural engineer or a trained technician, will inspect your home to pinpoint any weaknesses and suggest the best solutions for improvement.

    This assessment includes a thorough inspection of the foundation, walls, roof, and overall structure. Following this, our engineer will create a detailed retrofitting plan tailored to the results.

    Foundation Bolting

    Strengthening the foundation is the next step in this process. Our technicians install anchor bolts to secure your home to its foundation, helping to prevent lateral movement during an earthquake.

    Our process in Damascus involves drilling into the foundation and inserting robust steel bolts. The team then tightens these bolts to strengthen your structure, boosting its stability and resistance to seismic forces.

    Adding Shear Walls

    In Damascus, OR, shear walls play a crucial role in earthquake retrofitting by helping to distribute seismic forces and protect buildings from collapsing.

    Shear walls are often made from plywood or other sturdy materials, strategically installed in key areas of your home, especially in cripple walls. These walls enhance support and stability, helping to minimize the risk of damage during an earthquake in Damascus.

    Bracing & Reinforcing

    Next, we strengthen essential areas of your home in Damascus with durable steel braces and straps. Our team carefully installs these reinforcements on key structural components like the roof, walls, and floors. This crucial step enhances your home’s overall stability, providing a solid framework designed to withstand seismic forces.

    Securing Applicances

    By securing appliances, you can create a safer home for everyone in Damascus. It’s important to anchor items like water heaters and refrigerators. Our technicians will also install safeguards 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.

    TerraFirma took care of the issues under warranty. I appreciated the good service recovery.
    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!

    Our house is built in the SW hills of Portland originally in 1938, with a 2003 addition. TerraFirma waterproofing product has been a significant update to a...
    This may not have been Terrafirma's biggest project but it was big to us. From the very beginning of diagnosis, estimates/proposals, the project management and communications, hand digging and cleanup, the entire crew made this stressful and expensive project very easy and seamless. Thank you Patrick, Brent, Mechelle and on site laborers(sorry I didn't get their names) for all of your amazing help.
    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.
    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.
    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...
    If you hire this company to put sump pumps in your basement, make sure you know exactly where they are going to put them and where the pipes that will pump the water outside will be coming out of your house. Even though one guy gives you a diagram ahead of time, that doesn’t mean the guy actually doing the work follows it. One sump pump was put in our basement just as we expected. The second one was not. We provided new electrical outlets dedicated for use to the sump pumps. The second pump now has cords hanging in mid air barely reaching the new plugs because that pump was not put where they told us it would be. Also, the pipes that take the water away from the house, we expected those to go through the foundation, not through the expensive cedar siding and be exposed on the front of our house! I was horrified to see those holes and said so. My husband redirected them to drill through the foundation so the pipes could not be seen once the work was done. They did that, but now we are left with holes to repair. They did not offer to repair them. The young men who did the work were kind and respectful and did what they thought were expected of them, but if you hire this company, make sure you know exactly where they are going to put everything and not assume anything even if you have a diagram!
    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!
