Foundation Repair Aumsville
Foundation problems can lead to significant damage to your home if not taken care of promptly. Signs like cracks in the floor, bowing walls, and sagging floors might indicate more serious issues beneath the surface. In Aumsville, OR, homeowners may also observe doors that stick, windows that don’t open or close easily, or noticeable gaps between walls and ceilings. These could all be indications that your foundation is shifting due to soil movement, water damage, or natural wear and tear over time.
At TerraFirma, we provide foundation repairs in Aumsville with expert solutions designed specifically for the unique challenges your home may face. Our process starts with a thorough inspection to identify the root cause and extent of your foundation issues. From there, we recommend one or more of our trusted repair systems to restore your home’s stability.
Foundation piers
Our push and helical piers are designed to stabilize and lift foundations by transferring their weight to deeper, more stable soil. Helical piers work best in areas with known soil conditions, while push piers are great for spots where soil stability is uncertain. Both systems are minimally invasive and provide lasting solutions for Aumsville homes.
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 confidence and peace of mind in your Aumsville home.
Basement Waterproofing Aumsville
Don’t let a damp basement turn into a bigger problem for your home in Aumsville. Excess moisture can lead to mold, mildew, and even structural damage, not to mention negatively impacting your air quality. Look out for musty odors, stained walls, standing water, or efflorescence—a white, powdery residue that appears when water evaporates. Even a tiny crack in your basement wall can invite unwanted moisture in.
TerraFirma provides top-notch basement waterproofing solutions in Aumsville, ensuring your space stays dry, healthy, and functional—rain or shine.
Crawl Space Repair Aumsville
Crawl spaces in Aumsville are often forgotten, but they play a vital role in your home’s structure and air quality. If not properly maintained, a neglected crawl space can attract mold, pests, and standing water. This can result in wood rot, unpleasant odors, and even respiratory problems for you and your family.
We understand the unique crawl space conditions in Aumsville, OR, and TerraFirma’s repair services are tailored to tackle moisture, mold, pests, and sagging floors with complete encapsulation, drainage solutions, and 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 Aumsville 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 Aumsville
Damaged, cracked, or uneven concrete isn’t just a visual eyesore—it can also pose safety risks. Issues like poor soil compaction, freeze-thaw cycles, erosion, or tree roots can lead to these problems. That’s why homeowners in Aumsville trust us for prompt and effective repairs on their concrete slabs, sidewalks, patios, and driveways.
TerraFirma provides quick, efficient, and durable concrete leveling and repair services right here in Aumsville, OR, utilizing cutting-edge polyurethane foam injection and effective crack sealing.
PolyLevel® Concrete Lifting
PolyLevel utilizes expanding polyurethane foam to elevate and stabilize concrete slabs. This non-invasive method is perfect for the residents of Aumsville, OR, looking to address:
- 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 Aumsville, OR for industrial buildings, warehouse floors, roads, runways, and rail lines—using the same high-quality systems we trust for residential properties.
Earthquake Retrofitting Aumsville, OR
Aumsville, like much of the Pacific Northwest, is situated in an area with active seismic activity. Homes built before the updated building codes of the 1990s are particularly at risk. Even a small earthquake could lead to your home shifting off its foundation or suffering significant structural damage.
TerraFirma’s earthquake retrofitting services help secure your Aumsville home to its foundation and strengthen its ability to withstand seismic events.
Retrofitting your home for earthquakes in Aumsville not only enhances safety but can also lead to lower insurance premiums and deductibles, plus eligibility for coverage options that may not have been available before the upgrade.
How We Retrofit
Assessment & Planning
In Aumsville, the retrofitting process starts with a thorough evaluation of your building’s condition. A qualified professional, like a structural engineer or a trained technician, will inspect your home to pinpoint any weaknesses and suggest the best solutions.
This evaluation involves inspecting the foundation, walls, roof, and overall structure. Afterward, the engineer creates a detailed retrofitting plan tailored to the findings.
Foundation Bolting
Securing the foundation is the crucial next step in our process. Our technicians expertly install anchor bolts to firmly connect your home to its foundation, ensuring it remains stable and secure during an earthquake.
Our process includes carefully drilling into the foundation and adding sturdy steel bolts. Our skilled team then tightens these bolts to reinforce the structure, boosting its stability and resilience against seismic activity.
Adding Shear Walls
In Aumsville, shear walls play a vital role in earthquake retrofitting by helping to distribute seismic forces, ensuring that buildings remain sturdy and safe during quakes.
In Aumsville, shear walls are commonly made from plywood or other sturdy materials, carefully placed in key areas of your home, especially within cripple walls. This added support enhances your walls’ stability, helping to lower the risk of damage during an earthquake.
Bracing & Reinforcing
Next, we strengthen key areas of your home in Aumsville with steel braces and straps. Our team carefully installs these reinforcements on critical structural elements like the roof, walls, and floors. This step enhances the overall stability of your home, ensuring it has a robust framework that can withstand seismic forces.
Securing Applicances
Securing your appliances is key to creating a safer home in Aumsville. Anchoring important items like water heaters and refrigerators is essential. Our technicians can also install protection for gas meters 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.
