    Foundation Repair Roy

    Foundation issues can lead to significant damage to your home if not addressed promptly. In Roy, WA, you might find signs like floor cracks, bowing walls, and sagging floors, which often indicate deeper structural problems. Homeowners may also notice sticking doors, windows that don’t close quite right, or gaps between the walls and ceilings. These issues can all point to shifting foundations caused by soil movement, water damage, or the natural aging process of your home.

    At TerraFirma, we specialize in foundation repairs right here in Roy, offering targeted solutions designed to address the specific issues affecting your home. Our process starts with a thorough inspection to identify the extent and source of the problem. After that, we recommend one or more of our trusted foundation repair systems tailored to your needs:

    Foundation piers

    In Roy, WA, our push and helical piers are designed to stabilize and lift your foundation by transferring its weight to deeper, more reliable soil. Helical piers work best in areas with known soil conditions, while push piers are perfect for locations where soil stability may be uncertain. 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 professional installation, ongoing maintenance options, and transferable warranties, so you can feel confident and relaxed in your Roy home.

    Basement Waterproofing Roy

    Dealing with a wet basement in Roy, WA? It can lead to serious issues like mold, mildew, structural damage, and poor air quality in your home. You might notice musty odors, stained walls, standing water, or a white powdery residue called efflorescence that forms when water evaporates. Even a tiny crack in your basement wall can become a gateway for moisture to enter, so it’s important to address any issues early on!

    TerraFirma provides state-of-the-art basement waterproofing solutions in Roy, ensuring your home stays dry, healthy, and functional—regardless of the weather.

    In Roy, WA, we design and install custom drainage systems that effectively redirect 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 your basement in Roy, WA not only safeguards your investment but also turns it into a safe and usable space for 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:

    Earthquake Retrofitting Roy, WA

    Roy, WA, is located in an active seismic zone, making it crucial for homeowners to be aware of their property’s safety. Homes built before the updated building codes of the 1990s may be especially at risk. Even a small earthquake can cause significant issues, like shifting off foundations or experiencing serious structural damage.

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

    Earthquake retrofitting in Roy not only strengthens your home but can also help lower your insurance premiums and deductibles, making you eligible for coverage options you may not have had before.

    How We Retrofit

    Assessment & Planning

    In Roy, WA, the retrofitting process starts with a thorough assessment 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.

    Our evaluation covers the foundation, walls, roof, and overall structure of your home here in Roy, WA. After our thorough assessment, our engineer will create a detailed retrofitting plan tailored to your specific needs.

    Foundation Bolting

    In Roy, WA, the next crucial step is securing your home’s foundation. Our technicians carefully install anchor bolts to tie the house to its foundation, keeping it stable and safe from lateral movement during an earthquake.

    In this process, we drill into the foundation and insert sturdy steel bolts. Our team then tightens these bolts to reinforce the structure, improving its stability and helping it withstand seismic activity.

    Adding Shear Walls

    In Roy, WA, shear walls play a vital role in earthquake retrofitting by helping to distribute seismic forces, ensuring your home remains standing strong during an earthquake.

    Shear walls are usually made from sturdy materials like plywood, and are installed in key areas of your home, especially in cripple walls. They give your walls extra support and stability, helping to minimize the risk of damage during an earthquake.

    Bracing & Reinforcing

    Next, we focus on strengthening essential parts of your home in Roy with durable steel braces and straps. Our team installs these reinforcements on key structural elements like the roof, walls, and floors. This crucial step enhances your home’s overall stability, creating a robust framework that can better withstand seismic forces.

    Securing Applicances

    Securing your appliances is key to creating a safer home in Roy, WA. It’s important to anchor essential items like water heaters and refrigerators. Our technicians also provide 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.
