    Foundation Repair Ontario

    Foundation issues can lead to significant damage to your home if not addressed promptly. In Ontario, OR, homeowners may notice signs like floor cracks, bowing walls, and sagging floors, all of which could indicate deeper structural problems. You might experience doors that stick, windows that won’t close properly, or gaps between your walls and ceilings. These symptoms can signal that your foundation is shifting due to soil movement, water damage, or natural aging. Don’t wait—take action to protect your home!

    At TerraFirma, we specialize in foundation repairs right here in Ontario, OR, offering expert solutions designed specifically for the unique issues affecting your home. Our process starts with a thorough inspection to accurately assess the problem’s extent and source. From there, we’ll recommend one or more of our trusted foundation repair systems to get your home back on solid ground.

    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 work best in areas with known soil conditions, while push piers are ideal for locations where soil stability is uncertain. Both systems are minimally invasive and provide permanent 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, providing you with confidence and peace of mind in your Ontario home.

    Basement Waterproofing Ontario

    A wet basement can cause a host of issues in your Ontario home, from mold and mildew to structural damage and poor air quality. 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 turn into a significant entry point for moisture.

    TerraFirma provides advanced basement waterproofing solutions in Ontario, OR, ensuring your space stays dry, healthy, and functional, whatever the weather brings.

    We create custom drainage systems that direct water away from your basement and into sump pumps, safeguarding your foundation.

    Basement Drainage System: Our most popular system, it’s installed below the floor slab and above the footing to prevent clogging.
    Perimeter Drainage System: Ideal for monolithic foundations where jackhammering is not feasible.
    Thin-floor Drainage System: A thin-floor drain system used in basements with thin concrete slabs.
    Grated Trench Drain: Block ground air from entering while allowing water to drain.

    We offer several sump pump options tailored to your water exposure:

    Multi-pump Sump System: Three-pump system for maximum protection, including battery backup for power outages.
    Battery Backup Sump Pump: High-capacity battery backup pump that activates when the main pump fails or power goes out.
    Basement Sump Pump System: A single-pump system for homes with minor water issues.

    Vapor Barrier Elite: A heavy-duty wall liner that stops moisture and mold while directing water into drainage systems.
    Basement Dehumidifier Sedona & XP: Energy-efficient dehumidifiers that remove up to 109 pints of moisture daily, improving air quality and comfort.

    Our Basement Window Well Enclosure and Window Well Drainage System keep your basement bright, dry, and free from debris, while meeting egress codes for safety.

    Waterproofing in Ontario, OR not only safeguards your investment but also transforms your basement into a safe and usable extension of your home.

    Encapsulation & Drainage

    We begin by sealing the crawl space with our Vapor Barrier, 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.

    Damaged, cracked, or uneven concrete isn’t just an eyesore; it can also pose safety risks. These issues often arise from poor soil compaction, freeze-thaw cycles, erosion, or tree root growth.

    Earthquake Retrofitting Ontario, OR

    Ontario, OR, is situated in an active seismic zone that’s a part of the Pacific Northwest. Homes constructed before the updated building codes of the 1990s may be particularly at risk. Even a minor earthquake can lead to significant structural damage or cause a home to shift off its foundation.

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

    By retrofitting your home in Ontario for earthquakes, you can also enjoy lower insurance premiums, reduced deductibles, and even access to coverage options that weren’t available before the upgrade.

    How We Retrofit

    Assessment & Planning

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

    Our evaluation looks closely at the foundation, walls, roof, and overall structure. From these findings, our engineer creates a detailed retrofitting plan tailored to your needs.

    Foundation Bolting

    Securing the foundation is the next crucial step in this process. Our technicians install anchor bolts to firmly connect your home to its foundation, helping to prevent any shifting during an earthquake.

    This process includes drilling into the foundation and placing steel bolts. The crew then tightens the bolts to reinforce the structure, boosting its stability and improving resistance to seismic activity.

    Adding Shear Walls

    Shear walls play a vital role in earthquake retrofitting by helping to distribute seismic forces and ensuring the stability of buildings in Ontario, OR.

    Shear walls, usually made of plywood or other sturdy materials, are strategically placed throughout homes in Ontario, OR, especially in areas like cripple walls. These walls add crucial support and stability, helping to lower the risk of damage during an earthquake.

    Bracing & Reinforcing

    Next, we strengthen key areas of your home in Ontario, OR, by adding steel braces and straps. Our team installs these essential reinforcements to critical structural elements like the roof, walls, and floors. This important step boosts your home’s stability, giving it a solid framework designed to withstand seismic forces.

    Securing Applicances

    Ensuring your appliances are securely anchored makes for a safer living environment in Ontario, OR. It’s vital to stabilize items like water heaters and refrigerators. Our technicians can also install protection 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.

    this company is first class. from the initial estimate to the technician that did the actual work. they even saved me 50% of the initial estimate once they were onsite and saw that the work did not need to be as extensive as initially thought. I'll always call this company for future work!
    We have a lot of exposed aggregate concrete with many of the pieces that had become off level after 40 years. Terra Firma was the most cost effective option available to level out the existing concrete. I met with their representative and walked through the project. On the scheduled date they showed up on time and spent most the day working to level and adjust the concrete which worked on 98% of the pieces; I knew there may be some pieces that may not be able to be corrected and I accepted that premise going in. The crew worked diligently and did a great job overall! Total material used (foam) was more than had been contracted but Terra Firma agreed to split the difference with me to reduce that extra cost which I thought was a generous offer. I highly recommend Terra Firma for concrete leveling services!
    TerraFirma did a very professional job on my sidewalk. I would recommend them to my friends. I give them 5 star.
    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!
    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
    Very efficient and professional!
    The whole process was explained very well. The crew that came out was amazing, clean and knowledgeable. Would definitely recommend Terra Firma!
    We had a Great experience with TerraFirma, the guys Tony, Alex, Sebastien and Harley were professional, respectful, and always on time. Tony gave daily update with pictures and Always asked if we had any questions. We are very happy we chose TerraFirma with our foundation/crawl space project. Would highly recommend them!
    We were in the process of selling our house when the buyer's inspector thought our entire front porch concrete area and a supporting post needed to be replaced due to some minor settling of the concrete. I asked TerraFirma if they would send someone to come and inspect the area and get their opinion. Within a few days of my request, Walt Bateman, a System Design Specialist, came and did an inspection. After spending a lot of time measuring and inspecting the front porch area, Walt spend considerable time explaining to me that the buyer's inspector's recommendation was not warranted and he offered a reasonable and easier solution. I was very impressed with Walt's knowledge and his very simple and reasonable explanation of what he found. Walt was very easy to talk to and extremely personable. My experience with Walt and TerraFirma was extremely positive and I would highly recommend them for the services that they offer.
    We are very pleased with the job TerraFirma completed on our front walk-up. It wasn't a huge job, but their representative, Jeremy was first rate. Very professional and very pleasant demeanor.
