    Foundation Repair Clackamas

    Foundation problems can lead to significant damage to your home if not taken care of. Common signs like cracks in the floor, bowed walls, and sagging floors may indicate more serious structural issues. Homeowners in Clackamas, OR may also experience doors that stick, windows that don’t close properly, or gaps between walls and ceilings. These issues could be symptoms of foundation shifting caused by soil movement, water damage, or the effects of aging.

    At TerraFirma, we specialize in repairing foundations in Clackamas with expert solutions designed to address the specific causes of your foundation issues. Our process starts with a thorough inspection to evaluate the extent and source of the problem. Based on our findings, we’ll recommend one or more of our effective foundation repair systems:

    Foundation piers

    In Clackamas, OR, 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 known soil conditions, while push piers are the go-to option for regions where soil stability is uncertain. Both systems are minimally invasive and provide 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 Clackamas home.

    Basement Waterproofing Clackamas

    Experiencing a wet basement in Clackamas can result in mold, mildew, structural damage, and poor air quality in your home. Look out for signs of water intrusion like musty odors, stained walls, pooling water, or efflorescence—a white, powdery substance that appears when water evaporates. Even a tiny crack in your basement wall can become a significant pathway for moisture.

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

    We design and install personalized drainage systems that efficiently redirect water away from your basement and toward sump pumps, safeguarding your foundation in Clackamas.

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

    Crawl Space Repair Clackamas

    Crawl spaces in Clackamas are often neglected, but they play a vital role in your home’s structure and air quality. If left unchecked, a poorly maintained crawl space can become a breeding ground for mold, pests, and standing water. These issues can result in wood rot, unpleasant odors, and even respiratory problems for those living in your home.

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

    Chipped, cracked, or uneven concrete can be more than just an eyesore—it poses a safety risk too. These issues often arise from factors like inadequate soil compaction, freeze-thaw cycles, erosion, or even tree roots. That’s why homeowners in Clackamas turn to us for prompt and effective repairs on their concrete slabs, sidewalks, patios, and driveways.

    TerraFirma provides quick, efficient, and durable concrete leveling and repair services in Clackamas, OR, utilizing advanced polyurethane foam injection and expert crack sealing.

    PolyLevel® Concrete Lifting

    PolyLevel uses expanding polyurethane foam to lift and stabilize concrete slabs. This non-invasive method is perfect for residents of Clackamas, OR, looking to:

    • Sidewalks – Eliminates tripping hazards and restores smooth walkways.
    • Driveways – Prevents further cracking and improves curb appeal.
    • Patios, Porches, and Pool Decks – Ensures proper drainage and surface stability.

    NexusPro™ Crack & Joint Sealant

    To prevent water intrusion that can lead to further sinking, we apply NexusPro, a UV-resistant silicone-based joint sealant that:

    • Cures in just 60 minutes.
    • Withstands extreme weather and heavy use.
    • Includes color-matched sand for a clean, polished look.

    SealantPro™ Concrete Protection

    After sealing and lifting your concrete, SealantPro provides a long-term barrier against moisture, chemicals, and seasonal temperature changes. It penetrates deep into concrete to resist stains, flaking, and surface erosion.

    We also provide commercial concrete repair in Clackamas, OR for industrial buildings, warehouse floors, roads, runways, and rail lines—using the same high-quality systems we trust for residential properties.

    Earthquake Retrofitting Clackamas, OR

    In Clackamas, OR, we’re situated in an active seismic zone of the Pacific Northwest. Homes built before the updated building codes from the 1990s may be particularly at risk. Even a minor earthquake can lead to a house shifting off its foundation or suffering serious structural damage.

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

    Earthquake retrofitting in Clackamas not only enhances your home’s safety but can also lower your insurance premiums and deductibles, plus help you qualify for coverage that wasn’t available before the upgrade.

    How We Retrofit

    Assessment & Planning

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

    This evaluation involves inspecting the foundation, walls, roof, and overall structure. Based on the findings, the engineer will create a thorough retrofitting plan tailored for your needs.

    Foundation Bolting

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

    Our process includes drilling holes into the foundation and inserting steel bolts, which our team then tightens to strengthen the structure. This not only boosts stability but also improves resistance to seismic forces, ensuring your home in Clackamas is well-protected.

    Adding Shear Walls

    Shear walls play a vital role in earthquake retrofitting in Clackamas, helping to distribute seismic forces and ensuring that buildings remain safe and secure.

    Shear walls are usually made from plywood or other durable materials and are installed in key areas of your home, especially in cripple walls. They add extra support and stability to the walls, helping to minimize the risk of damage during an earthquake, which is especially important for residents in Clackamas.

    Bracing & Reinforcing

    Next, we’ll strengthen vital areas of your home in Clackamas with durable steel braces and straps. Our skilled team installs these reinforcements on essential structural components like the roof, walls, and floors. This important step enhances your home’s overall stability, providing a robust framework that can endure seismic activity.

    Securing Applicances

    Securing your appliances is key to creating a safer home in Clackamas. Anchoring items like water heaters and refrigerators is essential, and our technicians can also install safety measures for gas meters to help 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.

    Jaden was prompt, professional and courteous. I would recommend him to anyone who requires his services.
    Both crew's were on time. The crawlspace crew put down plastic from the front door to the crawlspace entrance in a bedroom. Work was completed on time, our closet doors reattached and the areas they worked in or went through left clean and tidy. The sidewalk crew completed their work in a day and even patched a crack we had forgotten to mention to the estimator. If TerraFirma also did crawlspace insulation, that would have been great, but I had to find another company for the insulation.
    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!
    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.
    We had an excellent installation on a fantastic crawl space waterproofing job. We are on the northern Oregon coast and a few feet from the sand so we get a lot of moisture under our 1940s home. We decided to invest in the TerraFirma product after a great meeting last summer with Don as we were taking on a major house renovation and decided we would do what is best all at once. We are very happy we did as the product is a game changer for the health of our home and our next generation. We pick up some great additional waterproofed storage space too in the end. The install process was efficient, and we had three outstanding guys working our job. Antonio, Jesse and Cameron deserve a big shout out. They spent time each day we dropped by to educate us on what they did that day, show us every aspect of the job and took great care to be hospital-like clean. Sometimes not-so -ice people do very good work, and sometimes really nice people do shabby work but in our case with TerraFirma, we received an excellent service from very nice guys. So glad we found Terra Firma!
    We were very happy with the work performed by the Terra Firma crew assigned to our crawlspace drainage problem. There was a project foreman assigned to the product (Luis,) and George and Christian were the other two workers. They were prompt, extremely hard-working, very clean and careful with the materials they used. We are very happy with the work of the Terra Firma crew and highly recommend them.
    We had a concrete driveway that was sinking on one side, large chunks of the pavement were completely detached. TerraFirma was quick to schedule an estimate. The estimate was thorough and a fair price. They were flexible with scheduling for the job itself. They arrived at the scheduled time, did an awesome job of cleaning the cracks, leveling everything, and sealing the cracks. The material to seal the cracks needed to be avoided by our dog for half a day to be safe just to prevent her nails from digging into it while it finished curing, but otherwise we were able to immediately walk on the driveway. It looks fantastic. If you're looking to give your exterior a visual improvement as well as prevent erosion of your driveway/foundation, this is such a great solution. The warranty is great too. Well worth the price. We feel comfortable moving on to additional projects that the driveway impacts, knowing it is sturdy.
