Foundation Repair Newberg
Foundation issues can lead to significant damage to your home if not addressed promptly. Signs like cracked floors, bowing walls, and sagging floors may indicate more serious structural concerns. Residents of Newberg, OR may also experience sticking doors, windows that don’t close properly, or noticeable gaps between walls and ceilings. These symptoms could point to foundation shifting due to soil movement, water damage, or simply the aging of your home.
At TerraFirma, we specialize in foundation repairs in Newberg, offering expert solutions designed specifically for the root cause of your foundation issues. We start with a thorough inspection to evaluate the extent and source of the problem. 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 load to deeper, more reliable soil. Helical piers are a great choice for areas with known soil conditions, while push piers work well in places where soil stability is uncertain. Both systems are minimally invasive and provide lasting solutions to your foundation issues right here in Newberg.
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 professional installation, reliable maintenance options, and transferable warranties, ensuring you feel confident and at ease in your Newberg home.
Basement Waterproofing Newberg
Dealing with a damp basement in Newberg can lead to mold, mildew, structural issues, and decreased air quality in your home. You might notice signs like musty odors, stained walls, standing water, or even white, powdery residue left after water evaporates. Remember, even a tiny crack in your basement wall can create a significant pathway for moisture.
TerraFirma provides top-notch basement waterproofing solutions in Newberg, ensuring your space stays dry, healthy, and functional—come rain or shine.
Crawl Space Repair Newberg
Crawl spaces in Newberg may often be forgotten, but they play a vital role in your home’s structure and air quality. When neglected, these spaces can become a breeding ground for mold, pests, and standing water. This can result in wood rot, unpleasant odors, and respiratory problems for you and your family.
We understand the crawl space conditions in Newberg, OR, and TerraFirma’s repair services are tailored to tackle moisture, mold, pests, and sagging floors with comprehensive solutions like 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 Newberg 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 Newberg
Cracked, uneven, or damaged concrete isn’t just an eyesore—it can also pose a safety risk. These issues often arise from factors like poor soil compaction, freeze-thaw cycles, erosion, or tree roots. Homeowners in Newberg trust us to promptly and effectively repair their concrete slabs, sidewalks, patios, and driveways.
TerraFirma provides quick, efficient, and durable concrete leveling and repair services right here in Newberg, OR, using cutting-edge polyurethane foam injection and expert crack sealing.

- 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.

Earthquake Retrofitting Newberg, OR
Newberg, OR, is located in an area of the Pacific Northwest that is prone to earthquakes. Homes constructed before the 1990s, when updated building codes were put in place, are particularly at risk. Even a minor quake can lead to shifts in a home’s foundation or result in significant structural damage.
TerraFirma’s earthquake retrofitting services help secure your Newberg home to its foundation and strengthen its ability to withstand seismic events.
Retrofitting your home in Newberg not only enhances earthquake safety but can also help lower your insurance premiums and deductibles, plus may qualify you for coverage options that weren’t available before the upgrade.
How We Retrofit
Assessment & Planning
In Newberg, OR, the retrofitting process starts with a thorough evaluation of your building’s current condition. A qualified expert, like a structural engineer or skilled technician, will inspect your home to pinpoint any weaknesses and suggest the right solutions.
This assessment covers the foundation, walls, roof, and overall structure of your home. Based on the findings, our engineer will create a detailed retrofitting plan tailored to your needs.
Foundation Bolting
Securing the foundation is the next step in the process. Our technicians will install anchor bolts that connect your home to its foundation, ensuring it stays steady and secure during an earthquake.
Our team will carefully drill holes into your foundation and install sturdy steel bolts. By tightening these bolts, we’ll secure your structure, boosting its stability and resilience against seismic activity.
Adding Shear Walls
Shear walls play a vital role in earthquake retrofitting by managing seismic forces and helping to keep buildings in Newberg safe from collapse.
Shear walls, usually made of plywood or other sturdy materials, are placed in key spots around your home, especially in cripple walls. They offer extra support and stability, helping to lower the risk of damage during an earthquake.
Bracing & Reinforcing
Next, we focus on strengthening important areas of your home using steel braces and straps. Our team expertly installs these to crucial structural components like the roof, walls, and floors. This step boosts your home’s stability, creating a solid framework designed to endure seismic activity, especially important here in Newberg.
Securing Applicances
“Securing your appliances helps create a safer home for everyone in Newberg. Anchoring essential items like water heaters and refrigerators is crucial. Our skilled technicians will also provide protection for gas meters to minimize 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.
