Foundation Repair Eugene
Foundation issues can lead to significant damage to your home if they’re not taken care of promptly. Symptoms like floor cracks, bowing walls, and sagging floors often indicate more serious structural problems. Homeowners in Eugene, OR might experience sticking doors, windows that won’t close properly, or noticeable gaps between walls and ceilings. These signs could mean that your foundation is shifting due to soil movement, water damage, or the effects of aging.
At TerraFirma, we specialize in foundation repair right here in Eugene, offering expert solutions designed specifically for the unique challenges your home may face. We start with a thorough inspection to understand the extent and cause of your foundation issues. From there, we 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 are great for areas with known soil conditions, while push piers work best in places with uncertain stability. Both options are minimally invasive and provide lasting solutions for your home in Eugene.
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, maintenance options, and transferable warranties—providing you with confidence and peace of mind in your home here in Eugene.
Basement Waterproofing Eugene
Dealing with a wet basement in Eugene? It can lead to problems like mold, mildew, structural damage, and poor air quality in your home. You might notice musty smells, stained walls, pooling water, or efflorescence—a white, powdery residue that appears when water evaporates. Even a tiny crack in your basement wall can turn into a significant gateway for moisture.
TerraFirma provides top-notch basement waterproofing solutions in Eugene, ensuring your space stays dry, healthy, and functional—whatever the weather brings.
Crawl Space Repair Eugene
Crawl spaces are often forgotten, but they play a vital role in your home’s structure and air quality here in Eugene. If neglected, these spaces can become a breeding ground for mold, pests, and standing water. This not only leads to wood rot and unpleasant odors but can also impact the health of everyone living in your home.
We understand the unique crawl space conditions in Eugene, OR, and TerraFirma’s repair services are tailored to tackle moisture, mold, pests, and sagging floors. Our solutions include full encapsulation, effective drainage, and structural support to keep your home safe and dry.

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 Eugene 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 Eugene
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 lead to these problems. Homeowners in Eugene trust us to promptly and effectively restore their concrete slabs, sidewalks, patios, and driveways.
TerraFirma provides quick, reliable, and durable concrete leveling and repair services in Eugene, OR, using innovative 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 residents in Eugene, 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 Eugene, OR for industrial buildings, warehouse floors, roads, runways, and rail lines—using the same high-quality systems we trust for residential properties.
Earthquake Retrofitting Eugene, OR
Much of the Pacific Northwest, including Eugene, sits in an active seismic zone. Homes constructed before the updated building codes were implemented in 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 Eugene home to its foundation and strengthen its ability to withstand seismic events.
Retrofitting your home for earthquakes in Eugene not only strengthens your property, but it can also lead to lower insurance premiums and deductibles, and even help you qualify for coverage options that weren’t available before the upgrade.
How We Retrofit
Assessment & Planning
The retrofitting process starts with a thorough evaluation of your building’s current state. A qualified professional, like a structural engineer or a trained technician, will inspect your home to pinpoint any weaknesses and suggest the best solutions tailored for Eugene.
This assessment involves a thorough inspection of the foundation, walls, roof, and overall structure. From there, our engineer will create a detailed retrofitting plan tailored to the unique needs of your property.
Foundation Bolting
Ensuring your home’s foundation is secure is the next important step. Our technicians install anchor bolts to firmly connect your house to its foundation, providing protection against lateral movement during an earthquake—something we take seriously here in Eugene.
Our process starts with carefully drilling into the foundation and inserting sturdy steel bolts. Our skilled team tightens these bolts to reinforce the structure, boosting its stability and resilience against seismic activity.
Adding Shear Walls
Shear walls play a vital role in earthquake retrofitting by helping to distribute seismic forces and keeping buildings in Eugene safe from collapse.
Shear walls, often made from plywood or other durable materials, are strategically installed throughout homes, especially in areas like cripple walls. They enhance the support and stability of your home, helping to minimize the risk of damage during an earthquake—a crucial consideration for our community here in Eugene.
Bracing & Reinforcing
Next, we enhance the critical areas of your home in Eugene with durable steel braces and straps. Our team carefully installs these reinforcements on essential structural elements like the roof, walls, and floors. This important step boosts your home’s overall stability, giving it a solid framework designed to withstand seismic forces.
Securing Applicances
Securing your appliances is key to creating a safer home for you and your family. Anchoring items like water heaters and refrigerators is essential in preventing accidents. Our technicians will also add protective measures for gas meters to help 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.
