Foundation Repair Medina
Foundation issues can lead to significant damage to your home if not addressed promptly. In Medina, WA, homeowners may spot signs like cracks in the floor, bowing walls, or uneven floors, which often point to deeper structural concerns. You might also notice sticky doors, windows that won’t close properly, or gaps between walls and ceilings. These could all indicate that your foundation is shifting due to soil movement, water damage, or the natural aging process of your home.
At TerraFirma, we specialize in foundation repairs right here in Medina, offering expert solutions that address the specific causes of your foundation issues. Our process starts with a thorough inspection to determine the extent and source of the problem. After that, we’ll recommend one or more of our reliable foundation repair systems:
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 for known soil conditions, while push piers are the ideal choice for areas with uncertain soil stability. Both solutions are minimally invasive and provide lasting results for your home in Medina.
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, ensuring you feel confident and at ease in your Medina home.
Basement Waterproofing Medina
Having a wet basement in Medina can cause serious issues like mold, mildew, structural damage, and compromised air quality in your home. You might notice signs of water intrusion such as musty odors, stained walls, puddles, or that white, powdery residue known as efflorescence left behind when water evaporates. Even a tiny crack in your basement wall could become a gateway for moisture to enter.
TerraFirma provides cutting-edge basement waterproofing solutions in Medina, ensuring your home stays dry, healthy, and functional—whatever the weather brings.
Crawl Space Repair Medina
Don’t let your crawl space go unnoticed! Here in Medina, WA, it plays an essential role in your home’s structure and air quality. If neglected, your crawl space can become a breeding ground for mold, pests, and standing water, potentially leading to wood rot, unpleasant odors, and even respiratory problems for your family. Keep your home healthy by giving your crawl space the attention it deserves!
We understand the unique crawl space conditions in Medina, WA, and TerraFirma’s repair services are tailored to tackle issues like moisture, mold, pests, and sagging floors with comprehensive encapsulation, effective drainage, and sturdy 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.
Crawl Space Entry & Vent Solutions
- EverLast™ Doors & Access Wells: Waterproof, durable entry systems that keep out pests and moisture.
- Turtl™ Access Well: An attractive, lockable access solution in several colors.
- Vent Covers: Sealing crawl space vents prevent outdoor air, moisture, and insects from entering.
Crawlspace repair in Medina is crucial to maintaining your home’s overall health and energy efficiency.
Structural Repairs
To support sagging or weak floor joists, our SmartJack® Support Posts offer adjustable, galvanized steel columns that restore floor stability. These are fast to install and offer permanent results.
Dehumidifiers & Monitoring
Install a SaniDry Sedona dehumidifier to maintain healthy humidity levels year-round. For added security, our ShipShape™ System offers 24/7 performance monitoring, proactive maintenance alerts, and remote control of your crawl space systems.
Concrete Repair Medina
Cracked, damaged, 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 roots. Residents of Medina trust us to swiftly and effectively repair their concrete slabs, sidewalks, patios, and driveways.
TerraFirma provides quick, efficient, and durable concrete leveling and repair solutions right here in Medina, WA, using state-of-the-art polyurethane foam injection and crack sealing techniques.
PolyLevel® Concrete Lifting
PolyLevel uses expanding polyurethane foam to lift and stabilize concrete slabs. This non-invasive method is perfect for residents of Medina, WA, looking to address:
- 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 Medina, WA for industrial buildings, warehouse floors, roads, runways, and rail lines—using the same high-quality systems we trust for residential properties.
Earthquake Retrofitting Medina, WA
Much of the Pacific Northwest, including Medina, is situated in an active seismic zone. Homes built before the updated building codes were introduced in the 1990s may be particularly at risk. Even a minor earthquake can cause homes to shift off their foundations or suffer significant structural damage.
TerraFirma’s earthquake retrofitting services help secure your Medina home to its foundation and strengthen its ability to withstand seismic events.
Earthquake retrofitting in Medina not only enhances your home’s safety but can also lower your insurance premiums and deductibles, while helping you qualify for coverage that wasn’t available before the upgrade.
How We Retrofit
Assessment & Planning
In Medina, WA, the retrofitting process starts with a thorough evaluation 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 best solutions to enhance its safety and stability.
This assessment looks at the foundation, walls, roof, and overall structure of your property. Our engineer then creates a detailed retrofitting plan tailored to the findings.
Foundation Bolting
Securing the foundation is the crucial next step. Our technicians install anchor bolts that firmly connect your home to its foundation, ensuring stability and preventing lateral movement during an earthquake right here in Medina, WA.
This process involves drilling into the foundation and installing steel bolts to secure the structure. Our team then tightens these bolts, boosting stability and improving resistance to seismic activity right here in Medina.
Adding Shear Walls
Shear walls play an essential role in earthquake retrofitting in Medina, as they help distribute seismic forces and keep buildings from collapsing.
In Medina, WA, shear walls are often made from plywood or other durable materials. Our experienced team installs them in key areas of your home, especially in cripple walls. This added support enhances the stability of your home, minimizing the risk of damage during an earthquake.
Bracing & Reinforcing
Next, we bolster essential areas of your Medina home with steel braces and straps. Our team expertly installs these to key structural elements, including the roof, walls, and floors. This vital step enhances your home’s stability, providing a solid framework designed to withstand seismic forces.
Securing Applicances
Ensuring your appliances are securely anchored can help create a safer home for everyone in Medina, WA. It’s important to stabilize items like water heaters and refrigerators. Our technicians also provide protection for gas meters 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.

Homeowners Frequently Asked Questions
How does rain put my home at risk ?
SeaTac soils are impacted by heavy rains causing hydrostatic pressure. This leads to cracks in foundations and basements and may cause your foundation to settle or sink. Engineered support structures and comprehensive drainage systems are key to keeping your home dry, safe, and stable.
What’s the best way to repair concrete?
The NexusPro solution is a commercial grade joint sealant that offers several advantages over traditional concrete crack repairs. Its fast cure time (60 minutes) and performance under extreme temperatures makes it a perfect match for concrete repairs.
What types of cracks in my foundation or basement should I be concerned with?
Houses are susceptible to cracks in basements due to heavy rains and wet soils. Watch out for horizontal or stair step cracking along the foundation wall, diagonal cracks in the corners, crumbling walls and inward bulges.
How to fix a leaking basement floor?
If you have water coming through the floor or windows to your basement, the first step is installing a perimeter drain system. We can also install a direct drainage channel, which will help direct any water that comes through the crack into the drain and your sump pump.
Are you noticing damp drywall and carpet in your basement?
Musty smells, walls that feel damp to the touch, and ground-level leaks are all indicators that your basement may need to be waterproofed. Don’t wait until the next heavy rain to protect your home from water damage.
Which vapor barrier is best for weeping walls?
The VaporLoc Elite Wall System is better for weeping walls than other commonly used vapor barriers. The VLE system has double sealed seams, waterproof material (not water-resistant), and is much thicker than vapor barriers available at retail stores.
Can I turn my crawl space into storage?
TerraFirma offers comprehensive encapsulation solutions to keep your crawl space clean, dry, and secure from outside threats. Our industry-leading vapor barrier system keeps out destructive moisture while greatly improving your indoor air quality. In most homes, TerraFirma can even encapsulate your crawl space, giving you a clean, dry area suitable for storage.
How to repair damaged concrete?
While you could seal concrete with urethane caulk found at your local big-box DIY store, that is a solution that is prone to cracking, bubbling and drying out over time. The local experts at TerraFirma are here to help with long lasting solutions to level seal your unprotected joints and cracked concrete.
What is that bad smell coming up from my drain?
Unwanted air and gasses are coming up through your home’s drain system. A great fix is our TrenchLock™ drain insert that can be installed in an existing trench drain to allow water down without allowing air to come up. The system comes with balls that fit over the drainage holes, which create an airtight seal when there is no water.
What is the difference between helical piers and push piers?
Helical piers and push piers are both types of foundation repair methods, but they differ in their design and installation process. The choice between helical piers and push piers depends on factors such as soil conditions and structural requirements. Helical piers are often preferred in areas with weak or unstable soil conditions.
How long does basement waterproofing last?
TerraFirma-installed waterproofing systems are expected to last decades with regular care & maintenance. We also warranty our installations, our WaterGuard and DryTrak drainage systems come with a transferrable lifetime warranty. Terms apply, view the details here. We stand by our work and the quality of the systems we install.
