Foundation Repair White City
Foundation issues can lead to significant damage to your home if not taken care of. Homeowners in White City, OR, may notice signs like cracks in the floor, bowing walls, or sagging floors, all of which can indicate more serious structural problems. You might also see doors that stick, windows that won’t close properly, or gaps between walls and ceilings. These issues can be warnings that your foundation is shifting due to soil movement, water damage, or the natural wear and tear of age.
At TerraFirma, we specialize in foundation repair right here in White City, offering expert solutions designed to address the root cause of your foundation issues. Our process starts with a detailed inspection to evaluate the extent and source of the problem. Once we have a clear understanding, we recommend one or more of our reliable foundation repair systems tailored to your needs.
Foundation piers
In White City, OR, our push and helical piers are designed to stabilize and lift your foundation by effectively transferring its weight to deeper, more stable soil. Helical piers work best in areas with known soil conditions, while push piers are ideal for locations with uncertain soil stability. Both options 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, ongoing maintenance options, and transferable warranties, ensuring you feel confident and at ease in your White City home.
Basement Waterproofing White City
In White City, a damp basement can cause issues like mold, mildew, structural damage, and poor air quality in your home. Signs of water intrusion may include musty odors, stained walls, pooling water, or a white, powdery residue called efflorescence that appears when water evaporates. Even a tiny crack in your basement wall can become a significant pathway for moisture.
TerraFirma provides top-notch basement waterproofing solutions in White City, ensuring your space stays dry, healthy, and functional—whatever the weather!
Crawl Space Repair White City
Crawl spaces in White City are often overlooked, but they play a vital role in your home’s structure and air quality. If left unattended, a neglected crawl space can become a haven for mold, pests, and standing water. These issues can result in wood rot, unpleasant odors, and even respiratory problems for those living in the home.
We understand the unique crawl space challenges in White City, OR. That’s why TerraFirma offers specialized crawl space repair services tailored to tackle moisture, mold, pests, and sagging floors, featuring complete encapsulation, reliable drainage solutions, 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 White 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 White City
Cracked, damaged, or uneven concrete isn’t just an eyesore—it’s a safety risk. These issues can arise from factors like poor soil compaction, freeze-thaw cycles, erosion, or tree root growth. That’s why homeowners in White City trust us to repair their concrete slabs, sidewalks, patios, and driveways quickly and effectively.
TerraFirma provides quick, clean, and durable concrete leveling and repair services in White City, OR, utilizing state-of-the-art polyurethane foam injection and crack sealing techniques.
PolyLevel® Concrete Lifting
In White City, OR, PolyLevel utilizes expanding polyurethane foam to lift and stabilize concrete slabs. This non-invasive method is perfect for:
- 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 White 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 White City, OR
White City, like much of the Pacific Northwest, is located in an active seismic zone. Homes built before the updated building codes of the 1990s are particularly at risk. Even a minor earthquake can cause significant shifting of foundations or lead to serious structural damage.
TerraFirma’s earthquake retrofitting services help secure your White City home to its foundation and strengthen its ability to withstand seismic events.
“Earthquake retrofitting in White City not only enhances your property’s safety but can also help lower your insurance premiums and deductibles. Plus, you may qualify for coverage options that weren’t available before the upgrade.”
How We Retrofit
Assessment & Planning
In White City, OR, the retrofitting process starts with a thorough assessment of your building’s current condition. A skilled expert—like a structural engineer or trained technician—will inspect your home to pinpoint any vulnerabilities and suggest the best solutions.
This assessment includes a thorough inspection of the foundation, walls, roof, and overall structure. Following this, our engineer will create a detailed retrofitting plan tailored to the findings.
Foundation Bolting
In White City, securing the foundation is the crucial next step. Our technicians professionally install anchor bolts to firmly connect your home to its foundation, ensuring stability and preventing any lateral movement during an earthquake.
In White City, OR, our process includes drilling into the foundation and inserting sturdy steel bolts. Our team tightens these bolts to reinforce the structure, boosting its stability and improving its resistance to seismic activity.
Adding Shear Walls
Shear walls play a vital role in earthquake retrofitting by helping to distribute seismic forces, ensuring that structures in White City can stand strong and safe.
In White City, OR, shear walls are usually made of plywood or other durable materials that are expertly installed in key areas of your home, especially within cripple walls. These essential elements offer added support and stability, significantly lowering the chance of damage during an earthquake.
Bracing & Reinforcing
Next, we fortify essential areas of your White City home with durable steel braces and straps. Our team installs these critical supports to key structural components like the roof, walls, and floors. This vital step enhances the overall stability of your home, providing a robust framework that can better withstand seismic forces.
Securing Applicances
Ensuring your appliances are secure helps create a safer living environment for everyone in White City. It’s important to anchor items like water heaters and refrigerators, and our technicians can also install protective measures for gas meters to minimize 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.
