    Foundation Repair Burien

    Foundation problems can lead to significant damage to your home if not taken care of promptly. Homeowners in Burien, WA, may notice signs like cracks in the floors, bowing walls, or sagging floors, which could indicate more serious structural issues. You might find that doors are sticking, windows won’t close right, or there are visible gaps between walls and ceilings—all of which can be indicators of a shifting foundation due to soil movement, water damage, or simply the wear and tear of time.

    At TerraFirma, we specialize in foundation repairs right here in Burien, delivering expert solutions that address the specific cause of your foundation issues. Our process starts with a thorough inspection to identify the extent and source of the problem, after which we’ll recommend one or more of our trusted foundation repair systems.

    Foundation piers

    In Burien, WA, our push and helical piers are designed to effectively stabilize and lift your foundation by transferring its load to deeper, more stable soil. Helical piers are perfect for areas with known soil conditions, while push piers are ideal for regions with uncertain soil stability. 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, flexible maintenance options, and transferable warranties, ensuring you feel confident and at peace in your Burien home.

    Basement Waterproofing Burien

    Dealing with a damp basement in Burien, WA? It can cause mold, mildew, structural issues, and even poor air quality in your home. Look out for signs like musty odors, stained walls, pooling water, or efflorescence—a white, powdery residue that appears when water evaporates. Remember, even a tiny crack in your basement wall could turn into a significant source of moisture.

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

    We design and install custom drainage systems in Burien that effectively divert 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 Burien, WA not only safeguards your investment but also turns your basement into a safe and functional extension of your home.

    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.

    Earthquake Retrofitting Burien, WA

    Burien, like much of the Pacific Northwest, is located in an active seismic zone. Homes constructed before the updated building codes of the 1990s may be particularly at risk. Even a small earthquake can lead to a house shifting off its foundation or suffering significant structural damage.

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

    Earthquake retrofitting in Burien not only strengthens your home, but it can also help lower your insurance premiums and deductibles, while qualifying you for coverage that may not have been available before the upgrade.

    How We Retrofit

    Assessment & Planning

    In Burien, WA, the retrofitting process starts with a thorough assessment of your building’s current condition. Our skilled professionals, including structural engineers and trained technicians, will inspect your home to pinpoint any weaknesses and suggest the most effective solutions.

    Our thorough evaluation covers everything from the foundation and walls to the roof and overall structure. After that, our engineer will create a detailed retrofitting plan tailored to the specific needs identified during the assessment.

    Foundation Bolting

    Next, we’ll secure the foundation to ensure your home in Burien is ready for anything. Our technicians install anchor bolts that connect your house to its foundation, providing stability and preventing any shifting during earthquakes.

    Our process involves drilling into the foundation and installing sturdy steel bolts. Our team then tightens these bolts to strengthen the structure, improving its stability and ability to withstand seismic activity.

    Adding Shear Walls

    Shear walls play a vital role in earthquake retrofitting by helping to distribute seismic forces and keeping buildings in Burien safe from collapse.

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

    Bracing & Reinforcing

    Next, we strengthen key areas of your Burien home with durable steel braces and straps. Our team expertly installs these reinforcements on essential structural elements like the roof, walls, and floors. This crucial step enhances your home’s stability, ensuring it has a robust framework that can withstand seismic forces.

    Securing Applicances

    Ensuring your appliances are securely anchored can greatly enhance the safety of your home in Burien, WA. It’s vital to anchor items like water heaters and refrigerators. Our technicians also offer installation of protective measures for gas meters, helping to 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.
