Foundation Repair Cottage Grove
Foundation issues can lead to significant damage to your home if not taken care of. In Cottage Grove, OR, you might see signs like cracks in your floors, bowing walls, or sagging floors, all of which could indicate deeper structural problems. Homeowners may also notice issues such as sticking doors, windows that won’t shut properly, or gaps appearing between walls and ceilings. These symptoms are often a sign that your foundation is shifting due to soil movement, water damage, or simply the passage of time.
At TerraFirma, we specialize in repairing foundations right here in Cottage Grove. Our expert team delivers targeted solutions that address the root cause of your foundation issues. We start with a thorough inspection to determine the extent and source of the problem, and then we recommend one or more of our reliable foundation repair systems.
Foundation piers
Our push and helical piers are expertly designed to stabilize and elevate your foundation by transferring its weight to deeper, more stable soil. Helical piers work well in areas with known soil conditions, while push piers are great for spots where soil stability is less certain. Both options are minimally invasive and provide lasting solutions for your home in Cottage Grove.
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, ensuring you have the confidence and peace of mind you need for your home in Cottage Grove.
Basement Waterproofing Cottage Grove
Living in Cottage Grove means you’re no stranger to rainy days, but a wet basement can lead to serious problems like mold, mildew, structural damage, and poor air quality in your home. If you notice musty odors, stained walls, pooling water, or efflorescence—a powdery residue left by evaporating water—it’s time to take action. Even a small crack in your basement wall can become a major gateway for moisture.
TerraFirma provides top-notch basement waterproofing solutions in Cottage Grove, ensuring your home stays dry, healthy, and functional—regardless of the weather.
Crawl Space Repair Cottage Grove
Crawl spaces are often easy to forget about, but they play a vital role in the structure of your home and the quality of the air you breathe. If left unattended, a neglected crawl space can invite mold, pests, and standing water. These problems can result in wood rot, unpleasant odors, and even respiratory issues for you and your family in Cottage Grove.
We understand the unique crawl space challenges in Cottage Grove, OR. That’s why TerraFirma offers tailored crawl space repair services to tackle moisture, mold, pests, and sagging floors through complete encapsulation, effective drainage, and reliable 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 Cottage Grove 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 Cottage Grove
Cracked, uneven, or damaged concrete is more than just an eyesore—it can also pose a safety risk. Issues like poor soil compaction, freeze-thaw cycles, erosion, or tree root growth can lead to these problems. Residents of Cottage Grove trust us to promptly and effectively repair their concrete slabs, sidewalks, patios, and driveways.
In Cottage Grove, OR, TerraFirma provides quick, efficient, and durable concrete leveling and repair services with 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 solution is perfect for Cottage Grove residents 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 Cottage Grove, OR for industrial buildings, warehouse floors, roads, runways, and rail lines—using the same high-quality systems we trust for residential properties.
Earthquake Retrofitting Cottage Grove, OR
Cottage Grove, like much of the Pacific Northwest, is situated in an active seismic zone. Homes constructed before the updated building codes from the 1990s may be particularly at risk. Even a small earthquake can lead to significant issues, such as shifting off its foundation or sustaining serious structural damage.
TerraFirma’s earthquake retrofitting services help secure your Cottage Grove home to its foundation and strengthen its ability to withstand seismic events.
Earthquake retrofitting in Cottage Grove not only enhances your home’s safety but can also lower your insurance premiums and deductibles, plus help you qualify for coverage that wasn’t available before the upgrade.
How We Retrofit
Assessment & Planning
In Cottage Grove, the retrofitting process starts with a thorough evaluation of your building’s current condition. A knowledgeable expert, like a structural engineer or trained technician, will inspect your home to pinpoint any weaknesses and suggest the best solutions for improvement.
“This evaluation involves inspecting the foundation, walls, roof, and overall structure. After that, our engineer creates a detailed retrofitting plan tailored to the findings.”
Foundation Bolting
Ensuring your home’s foundation is secure is the next important step. Our technicians will install anchor bolts to connect your house to its foundation, keeping it stable and preventing movement during an earthquake – a must for peace of mind here in Cottage Grove.
In Cottage Grove, our process starts with carefully drilling holes into your foundation and inserting sturdy steel bolts. Our team then tightens these bolts, ensuring the structure’s stability and improving its ability to withstand seismic activity.
Adding Shear Walls
In Cottage Grove, OR, shear walls play a vital role in earthquake retrofitting by effectively distributing seismic forces, helping to keep your home safe and sound during an earthquake.
Shear walls are usually made from plywood or other sturdy materials, expertly installed in key areas of your home, especially in cripple walls. They add crucial support and stability to your walls, helping to lower the risk of damage during an earthquake here in Cottage Grove.
Bracing & Reinforcing
Next, we strengthen key areas of your home in Cottage Grove by installing steel braces and straps. Our team carefully attaches these reinforcements to essential structural elements like the roof, walls, and floors. This step enhances your home’s overall stability, creating a robust framework designed to endure seismic forces.
Securing Applicances
Securing your appliances is key to creating a safer living environment in Cottage Grove, OR. Anchoring your water heaters and refrigerators is essential for peace of mind. Our technicians can 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.
