Foundation Repair Amity
Foundation issues can lead to significant damage to your home if not taken care of. Signs like floor cracks, bowing walls, and sagging floors often indicate more serious structural concerns. Homeowners in Amity, OR may also notice doors that stick, windows that don’t close properly, or visible gaps between walls and ceilings. These can all point to foundation shifts caused by soil movement, water damage, or the natural aging of your home.
At TerraFirma, we provide expert foundation repair services right here in Amity. Our tailored solutions are designed to address the specific causes of your foundation issues. We start with a detailed inspection to determine the extent and origin of the problem, and then we recommend one or more of our effective 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 where soil stability is uncertain. Both options are minimally invasive and provide long-lasting solutions for your home in Amity, OR.”
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, providing you with confidence and peace of mind in your Amity home.
Basement Waterproofing Amity
Living in Amity, OR, you might encounter challenges like a wet basement, which can pave the way for mold, mildew, and even structural damage. Signs of water intrusion can include musty odors, stained walls, standing water, or even a white, powdery residue left behind as water evaporates. Remember, even a small crack in your basement wall can turn into a significant entry point for moisture.
TerraFirma provides top-notch basement waterproofing solutions in Amity, ensuring your space stays dry, healthy, and functional—come rain or shine.
Crawl Space Repair Amity
Crawl spaces in Amity, OR, are often overlooked, but they play a vital role in your home’s structure and air quality. If neglected, these areas can become breeding grounds for mold, pests, and standing water. This can lead to wood rot, unpleasant odors, and potential respiratory issues for you and your family.
We understand the crawl space conditions in Amity, OR, and TerraFirma’s repair services are tailored to tackle moisture, mold, pests, and sagging floors. Our solutions include full encapsulation, effective drainage, 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 Amity 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 Amity
Damaged, cracked, or uneven concrete isn’t just an eyesore—it can also be a safety issue. These problems often arise from factors like poor soil compaction, freeze-thaw cycles, erosion, or tree root growth. Residents of Amity turn to us for fast and effective solutions to repair their concrete slabs, sidewalks, patios, and driveways.
At TerraFirma in Amity, we provide quick, clean, and durable concrete leveling and repair solutions using state-of-the-art polyurethane foam injection and crack sealing techniques.
PolyLevel® Concrete Lifting
PolyLevel uses expanding polyurethane foam to lift and stabilize concrete slabs. This non-invasive solution is perfect for the residents of Amity, 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

- Cures in just 60 minutes.
- Withstands extreme weather and heavy use.
- Includes color-matched sand for a clean, polished look.
SealantPro™ Concrete Protection

We also provide commercial concrete repair in Amity, OR for industrial buildings, warehouse floors, roads, runways, and rail lines—using the same high-quality systems we trust for residential properties.
Earthquake Retrofitting Amity, OR
Here in Amity, OR, we’re located in an area that’s part of the Pacific Northwest’s seismic zone. Homes built before the safety codes were updated in the 1990s are at greater risk. Even a small earthquake could cause a home to shift off its foundation or suffer significant structural damage.
TerraFirma’s earthquake retrofitting services help secure your Amity home to its foundation and strengthen its ability to withstand seismic events.
Retrofitting your home for earthquake safety in Amity can help lower your insurance premiums and deductibles, plus it may qualify you for coverage options that weren’t available before the upgrade.
How We Retrofit
Assessment & Planning
In Amity, OR, the retrofitting process kicks off with a thorough evaluation of your building’s current state. A qualified expert, like a structural engineer or skilled technician, will inspect your home to pinpoint any weaknesses and suggest the best solutions.
This evaluation involves checking the foundation, walls, roof, and overall structure. After that, our engineer will create a detailed retrofitting plan tailored to the findings.
Foundation Bolting
Next up for your home in Amity is securing the foundation. Our technicians will install anchor bolts to firmly connect your house to its foundation, helping to prevent any sideways movement during an earthquake.
In Amity, our process involves drilling into the foundation and inserting sturdy steel bolts. Our team then tightens these bolts to reinforce the structure, boosting its stability and ability to withstand seismic forces.
Adding Shear Walls
In Amity, OR, shear walls play a vital role in earthquake retrofitting by helping to distribute seismic forces, which protects our buildings from collapsing in the event of an earthquake.
In Amity, OR, shear walls are commonly made from plywood or other durable materials, carefully placed in key areas of your home, especially in cripple walls. These walls add crucial support and stability, helping to minimize the risk of damage during an earthquake.
Bracing & Reinforcing
Next, we fortify important areas of your home in Amity with steel braces and straps. Our team carefully installs these on essential structural elements like the roof, walls, and floors. This crucial step enhances your home’s stability, creating a sturdy framework designed to withstand seismic forces.
Securing Applicances
Ensuring your appliances are secured can create a safer home for everyone in Amity, OR. It’s important to anchor items like water heaters and refrigerators, and our technicians can also install 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.
