Foundation Repair Tualatin
Foundation issues can lead to significant damage to your home if not addressed promptly. In Tualatin, OR, homeowners may notice warning signs like cracks in the flooring, bowing walls, and sagging floors—indicators of deeper structural concerns. You might find doors that stick, windows that don’t close correctly, or gaps appearing between walls and ceilings. These could all be signs of a shifting foundation caused by soil movement, water damage, or the natural aging of your home.
At TerraFirma, we specialize in foundation repair right here in Tualatin. Our expert team offers tailored solutions designed to address the specific causes of your foundation issues. We start with a thorough inspection to pinpoint the extent and source of the problem, and then we recommend the best foundation repair systems to meet your needs.
Foundation piers
In Tualatin, our push and helical piers are specially designed to stabilize and lift your foundation by channeling its weight to deeper, more stable soil. Helical piers work best in areas with known soil conditions, while push piers are ideal for situations where soil stability is uncertain. Both methods 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 professional installation, flexible maintenance options, and transferable warranties, providing you with confidence and peace of mind in your Tualatin home.
Basement Waterproofing Tualatin
Having a damp basement in Tualatin can result in mold, mildew, structural damage, and even impact the air quality in your home. You might notice signs of water intrusion like musty odors, discolored walls, pooling water, or efflorescence—a white, powdery residue that forms when water evaporates. Remember, even a small crack in your basement wall can allow moisture to seep in.
TerraFirma provides top-notch basement waterproofing solutions in Tualatin, ensuring your space remains dry, healthy, and functional—rain or shine.
Crawl Space Repair Tualatin
Crawl spaces are frequently forgotten, but they play a vital role in your home’s structure and air quality here in Tualatin. If not properly maintained, a neglected crawl space can become a breeding ground for mold, pests, and stagnant water. This can result in wood rot, unpleasant odors, and even health problems for those living in your home.
We understand the unique crawl space conditions in Tualatin, OR, and TerraFirma’s repair services are here to tackle issues like moisture, mold, pests, and sagging floors with comprehensive solutions including full encapsulation, effective drainage, and 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 Tualatin 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 Tualatin
Cracked, damaged, or uneven concrete isn’t just an eyesore; it can also pose safety risks. Issues like poor soil compaction, freeze-thaw cycles, erosion, or tree roots can cause these problems. That’s why homeowners in Tualatin trust us to quickly and effectively repair their concrete slabs, sidewalks, patios, and driveways.
TerraFirma provides quick, reliable, and durable concrete leveling and repair services for Tualatin residents, utilizing cutting-edge polyurethane foam injection and expert crack sealing.
PolyLevel® Concrete Lifting
PolyLevel utilizes expanding polyurethane foam to lift and stabilize concrete slabs. This non-invasive solution is perfect for residents of Tualatin, 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 Tualatin, OR for industrial buildings, warehouse floors, roads, runways, and rail lines—using the same high-quality systems we trust for residential properties.
Earthquake Retrofitting Tualatin, OR
Located in an active seismic zone, much of the Pacific Northwest—including Tualatin—faces unique challenges when it comes to earthquake safety. Homes built prior to the updated building codes introduced in the 1990s are particularly at risk. Even a minor earthquake can lead to significant issues, like a home shifting off its foundation or suffering serious structural damage.
TerraFirma’s earthquake retrofitting services help secure your Tualatin home to its foundation and strengthen its ability to withstand seismic events.
Enhancing your home with earthquake retrofitting in Tualatin not only strengthens its safety but can also lower your insurance premiums and deductibles, and may even open up coverage options that were unavailable before the upgrade.
How We Retrofit
Assessment & Planning
In Tualatin, OR, the retrofitting process starts with a thorough assessment of your building’s current condition. A skilled professional, like a structural engineer or trained technician, will inspect your home to pinpoint any weaknesses and suggest the best solutions.
This assessment involves a thorough inspection of the foundation, walls, roof, and overall structure. Following this, the engineer creates a detailed retrofitting plan tailored to the results.
Foundation Bolting
Next, we focus on securing your foundation. Our skilled technicians will install anchor bolts to firmly connect your home to its foundation, helping to prevent any movement during an earthquake.
This process includes drilling into the foundation and installing steel bolts. Our team then tightens these bolts to strengthen the structure, improving its stability and resistance to seismic activity.
Adding Shear Walls
In Tualatin, OR, shear walls play a vital role in earthquake retrofitting by helping to distribute seismic forces, ensuring your building stays safe and secure.
Shear walls, made from strong materials like plywood, are strategically placed throughout homes in Tualatin, especially in areas like cripple walls. These additions offer crucial support and stability, helping to minimize the risk of damage during an earthquake.
Bracing & Reinforcing
Next, we enhance the key structural elements of your home in Tualatin by strategically adding steel braces and straps. Our skilled team installs these reinforcements to vital areas like the roof, walls, and floors, significantly boosting your home’s stability. This ensures a strong framework capable of withstanding seismic forces.
Securing Applicances
By securing your appliances, you can create a safer living environment in Tualatin. Anchoring items like water heaters and refrigerators is essential for your peace of mind. Our technicians also install 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.

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.
