Foundation Repair Hillsboro
Foundation issues can lead to significant damage to your home if not addressed in time. In Hillsboro, OR, homeowners may notice signs like cracks in the floor, bowing walls, or sagging floors, which often point to more serious structural concerns. You might also see doors that stick, windows that won’t close properly, or noticeable gaps between walls and ceilings. These could indicate that your foundation is shifting due to soil movement, water damage, or natural aging.
At TerraFirma, we provide expert foundation repair services right here in Hillsboro, tailored to address the specific causes of your foundation issues. We start with a thorough inspection to evaluate the extent and source of the problem, and then we recommend one or more of our trusted foundation repair solutions:
Foundation piers
In Hillsboro, OR, our push and helical piers are expertly designed to stabilize and elevate your foundation by shifting its load to deeper, more stable soil. Helical piers are great for areas with known soil conditions, while push piers are perfect if you’re unsure about the soil stability. Both solutions are minimally invasive and provide lasting results.
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, providing you with confidence and peace of mind in your Hillsboro home.
Basement Waterproofing Hillsboro
Living in Hillsboro, OR, you know how important it is to keep your home dry and comfortable. A wet basement can create problems like mold, mildew, structural damage, and even affect the air quality in your home. Look out for signs of water intrusion such as musty odors, stained walls, pooling water, or efflorescence—the white, powdery residue left behind when water evaporates. Remember, even the smallest crack in your basement wall can become a major gateway for moisture!
TerraFirma provides top-notch basement waterproofing solutions in Hillsboro, ensuring your space stays dry, healthy, and functional—come rain or shine.
Crawl Space Repair Hillsboro
Crawl spaces in Hillsboro often go unnoticed, but they play a vital role in your home’s structure and air quality. If not properly maintained, a neglected crawl space can become a breeding ground for mold, pests, and standing water. These issues can lead to wood rot, unpleasant odors, and even respiratory problems for you and your family.
We understand the crawl space conditions in Hillsboro, OR, and TerraFirma’s repair services are tailored to combat moisture, mold, pests, and sagging floors. Our comprehensive solutions include full encapsulation, drainage, and structural support to keep your home safe and sound.
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 Hillsboro 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 Hillsboro
Damaged, cracked, or uneven concrete can be more than just an eyesore—it poses a safety risk as well. Issues like poor soil compaction, freeze-thaw cycles, erosion, or tree root growth can lead to these problems. That’s why homeowners in Hillsboro trust us to quickly and effectively repair their concrete slabs, sidewalks, patios, and driveways.
TerraFirma provides quick, efficient, and durable concrete leveling and repair services in Hillsboro, OR, using cutting-edge polyurethane foam injection and expert crack sealing.
PolyLevel® Concrete Lifting
PolyLevel uses expanding polyurethane foam to lift and stabilize concrete slabs. This non-invasive method is perfect for Hillsboro homeowners 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 Hillsboro, OR for industrial buildings, warehouse floors, roads, runways, and rail lines—using the same high-quality systems we trust for residential properties.
Earthquake Retrofitting Hillsboro, OR
Hillsboro, like much of the Pacific Northwest, is situated in an active seismic zone. Homes built prior to the updated codes implemented in the 1990s are particularly at risk. Even a small earthquake can lead to homes shifting off their foundations or suffering significant structural damage.
TerraFirma’s earthquake retrofitting services help secure your Hillsboro home to its foundation and strengthen its ability to withstand seismic events.
Upgrading your home with earthquake retrofitting in Hillsboro can help lower your insurance premiums and deductibles, and may even make you eligible for coverage that wasn’t available before.
How We Retrofit
Assessment & Planning
The retrofitting process starts with a thorough inspection of your building’s current condition here in Hillsboro. A qualified expert, like a structural engineer or a trained technician, will assess your home to spot any weaknesses and suggest the best solutions.
This evaluation involves inspecting the foundation, walls, roof, and overall structure. Afterward, our engineer creates a detailed retrofitting plan tailored to the findings.
Foundation Bolting
Securing the foundation is the next step in ensuring your home in Hillsboro is protected. Our technicians install anchor bolts that connect your house to its foundation, helping to prevent any sideways movement during an earthquake.
This process includes drilling into the foundation and installing steel bolts. Our team then tightens these bolts to reinforce the structure, improving its stability and making it more resilient against seismic activity.
Adding Shear Walls
Shear walls play a vital role in earthquake retrofitting by helping to spread seismic forces, ensuring structures in Hillsboro remain safe and secure during an earthquake.
Shear walls are usually made from plywood or other durable materials, and they’re installed in key areas of your home, especially in cripple walls. These walls add extra support and stability, helping to lower the risk of damage during an earthquake here in Hillsboro.
Bracing & Reinforcing
Next, our team will strengthen key areas of your home in Hillsboro, OR, using steel braces and straps. These are carefully installed on essential structural elements like the roof, walls, and floors. This important step enhances your home’s overall stability, providing a robust framework that can endure seismic forces.
Securing Applicances
By securing your appliances, you can create a safer living environment for your home in Hillsboro, OR. Anchoring essential items like water heaters and refrigerators is crucial. Our technicians also install protective measures for gas meters to help 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.

Hillsboro
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.
