Foundation Repair North Plains
Foundation issues can lead to significant damage if not taken care of. Common signs like cracks in the floor, bowing walls, and sagging floors may indicate more serious structural problems. Homeowners in North Plains, OR, might find that doors stick, windows don’t close properly, or there are noticeable gaps between walls and ceilings. These could all mean that the foundation is shifting, often due to soil movement, water damage, or the natural aging of your home.
At TerraFirma, we specialize in repairing foundations right here in North Plains. We provide expert solutions tailored to the specific issues affecting your foundation. Our process starts with a thorough inspection to identify the root cause and extent of the problem. From there, we recommend one or more of our trusted foundation repair systems:
Foundation piers
In North Plains, OR, our push and helical piers are expertly designed to stabilize and lift your foundation by transferring its weight to deeper, more stable soil. Helical piers work best in known soil conditions, while push piers are the go-to solution for areas with unpredictable soil stability. Both systems are minimally invasive and provide lasting solutions for your foundation needs.
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, flexible maintenance options, and transferable warranties, ensuring you have confidence and peace of mind in your North Plains home.
Basement Waterproofing North Plains
Dealing with a wet basement in North Plains, OR? It can lead to mold, mildew, structural issues, and poor air quality in your home. Look out for musty odors, stained walls, pooling water, or efflorescence— that white powdery residue left behind when water evaporates. Even a tiny crack in your basement wall can turn into a serious pathway for moisture.
TerraFirma provides top-notch basement waterproofing solutions right here in North Plains, ensuring your space stays dry, healthy, and functional—rain or shine.
Crawl Space Repair North Plains
Crawl spaces in North Plains are often forgotten, but they play an essential 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 result in wood rot, unpleasant odors, and even health problems for you and your family.
At TerraFirma, we understand the unique crawl space challenges in North Plains, OR. Our expert crawl space repair services are tailored to tackle moisture, mold, pests, and sagging floors with comprehensive solutions that include full encapsulation, drainage, 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 North Plains 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 North Plains
Damaged, cracked, or uneven concrete isn’t just an eyesore; it can also pose a safety risk. Issues like poor soil compaction, freeze-thaw cycles, erosion, and tree root growth can lead to these problems. That’s why homeowners in North Plains trust us to quickly and effectively repair their concrete slabs, sidewalks, patios, and driveways.
TerraFirma proudly provides fast, efficient, and durable concrete leveling and repair solutions right here in North Plains, OR, utilizing advanced polyurethane foam injection and expert crack sealing.
PolyLevel® Concrete Lifting
At PolyLevel, we use expanding polyurethane foam to lift and stabilize concrete slabs. This non-invasive method is perfect for residents of North Plains, OR, who need:
- 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 North Plains, OR for industrial buildings, warehouse floors, roads, runways, and rail lines—using the same high-quality systems we trust for residential properties.
Earthquake Retrofitting North Plains, OR
North Plains, OR, is situated in an area of the Pacific Northwest that’s prone to seismic activity. Homes built before the updated building codes of the 1990s may be particularly at risk. Even a minor earthquake can lead to a house shifting off its foundation or suffering significant structural damage.
TerraFirma’s earthquake retrofitting services help secure your North Plains home to its foundation and strengthen its ability to withstand seismic events.
Enhancing your home in North Plains with earthquake retrofitting not only boosts safety but can also lower your insurance premiums and deductibles, and may help you qualify for coverage that was previously unavailable.
How We Retrofit
Assessment & Planning
The retrofitting process starts with a thorough evaluation of your building’s current condition. A professional, like a structural engineer or a qualified technician, will inspect your home to pinpoint any weaknesses and suggest the best solutions tailored for North Plains.
This evaluation involves a thorough inspection of the foundation, walls, roof, and overall structure. Based on the findings, our engineer will create a detailed retrofitting plan tailored to your needs.
Foundation Bolting
Securing the foundation is an essential next step. Our technicians will install anchor bolts to connect your home to its foundation, ensuring stability and preventing any lateral movement during an earthquake.
Our process includes drilling into your foundation and installing sturdy steel bolts. Our team then tightens these bolts to reinforce the structure, boosting its stability and helping it withstand seismic forces.
Adding Shear Walls
In North Plains, OR, shear walls play a vital role in earthquake retrofitting by effectively distributing seismic forces and helping to keep buildings safe from collapse.
In North Plains, OR, shear walls are typically made from plywood or other sturdy materials and are strategically installed throughout homes, especially in areas with cripple walls. These shear walls enhance the support and stability of your walls, helping to minimize the risk of damage in the event of an earthquake.
Bracing & Reinforcing
Next, we reinforce essential areas of your North Plains home using sturdy steel braces and straps. Our team carefully installs these materials on key structural elements like the roof, walls, and floors. This vital step enhances the overall stability of your home, ensuring it has a strong framework that can withstand seismic forces.
Securing Applicances
Securing your appliances is key to creating a safer home for everyone in North Plains. It’s important to anchor items like water heaters and refrigerators. Our technicians will also install safety features 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.

North Plains
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.
