Foundation Repair Junction City
Foundation issues can lead to significant damage to your home if not taken care of. Common signs like cracks in the floor, bowing walls, and sagging floors often indicate more serious structural concerns. Homeowners in Junction City, OR, may experience sticking doors, windows that won’t close properly, or noticeable gaps between walls and ceilings. These can all point to foundation shifts caused by soil movement, water damage, or the effects of aging.
At TerraFirma, we specialize in foundation repair in Junction City with solutions designed specifically for your unique needs. Our process starts with a thorough inspection to identify the root cause of your foundation issues. From there, we’ll suggest 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 shifting its load to deeper, more stable soil. Helical piers work best for known soil conditions, while push piers are excellent for areas with uncertain soil stability. Both systems are minimally invasive and provide lasting solutions for your foundation needs in Junction City.
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, so you can feel confident and at ease in your Junction City home.
Basement Waterproofing Junction City
Don’t let a damp basement in Junction City become a problem. It can lead to mold, mildew, structural damage, and poor air quality in your home. Keep an eye out for musty smells, stained walls, pooling water, or efflorescence—a white, powdery substance that appears when water evaporates. Even a small crack in your basement wall can turn into a major pathway for moisture.
TerraFirma provides top-notch basement waterproofing solutions in Junction City, ensuring your space stays dry, healthy, and functional, no matter what the weather brings.
Crawl Space Repair Junction City
Crawl spaces in Junction City, OR, are often neglected, but they play an essential role in your home’s structure and air quality. If left unattended, these spaces can become a breeding ground for mold, pests, and standing water. This can lead to problems like wood rot, unpleasant odors, and potential respiratory issues for you and your family.
We understand the unique challenges of crawl spaces in Junction City, OR. That’s why TerraFirma offers specialized crawl space repair services tailored to tackle moisture, mold, pests, and sagging floors, using solutions like full encapsulation, effective drainage systems, and robust 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 Junction City 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 Junction City
Cracked, damaged, or uneven concrete isn’t just an eyesore—it’s a safety risk. These issues can arise from poor soil compaction, freeze-thaw cycles, erosion, or even tree roots. In Junction City, homeowners trust us to swiftly and effectively repair their concrete slabs, sidewalks, patios, and driveways.
TerraFirma provides quick, clean, and durable concrete leveling and repair solutions for Junction City, OR, using state-of-the-art polyurethane foam injection and crack sealing techniques.
PolyLevel® Concrete Lifting

- 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 Junction City, OR for industrial buildings, warehouse floors, roads, runways, and rail lines—using the same high-quality systems we trust for residential properties.
Earthquake Retrofitting Junction City, OR
Junction City, like much of the Pacific Northwest, is situated in an active seismic zone. Homes built before the updated building codes of the 1990s are particularly at risk. Even a minor earthquake can lead to homes shifting off their foundations or suffering significant structural damage.
TerraFirma’s earthquake retrofitting services help secure your Junction City home to its foundation and strengthen its ability to withstand seismic events.
Getting your home retrofitted for earthquakes in Junction City can help lower your insurance premiums and deductibles, and may even make you eligible for coverage that wasn’t available before the upgrade.
How We Retrofit
Assessment & Planning
In Junction City, OR, the retrofitting process starts with a thorough evaluation of your building’s current condition. A skilled professional, like a structural engineer or a trained technician, will inspect your home to pinpoint any weaknesses and suggest the best solutions.
This assessment covers a thorough inspection of the foundation, walls, roof, and overall structure. After that, our engineer creates a detailed retrofitting plan tailored to the findings.
Foundation Bolting
In Junction City, OR, securing your home’s foundation is the next crucial step. Our technicians will install anchor bolts to firmly connect your house to its foundation, ensuring stability and preventing any movement during an earthquake.
This process includes drilling into the foundation and inserting steel bolts. Our team then tightens these bolts to secure the structure, boosting its stability and resilience against seismic activity.
Adding Shear Walls
In Junction City, OR, shear walls play a vital role in earthquake retrofitting by distributing seismic forces and helping to prevent structural collapse.
In Junction City, OR, shear walls are made from sturdy materials like plywood, strategically installed in key areas of your home, especially in cripple walls. These walls enhance your home’s support and stability, helping to minimize the risk of damage during an earthquake.
Bracing & Reinforcing
Next, we enhance key areas of your home in Junction City with sturdy steel braces and straps. Our team installs these vital supports on important structural elements like the roof, walls, and floors. This step boosts your home’s overall stability, ensuring it has a robust framework capable of withstanding seismic forces.
Securing Applicances
Ensuring your appliances are securely anchored can help create a safer home for everyone in Junction City, OR. It’s important to properly secure items like water heaters and refrigerators. Our technicians are also here to install protection for gas meters, reducing the risk of potential 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.

Junction City
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.
