Foundation Repair Beaverton
Foundation issues can lead to significant damage to your home if not taken care of. Homeowners in Beaverton, OR, may notice signs like cracks in the floors, bowing walls, and sagging floors, which often indicate more serious structural problems. You might find that doors stick, windows don’t close properly, or there are visible gaps between the walls and ceilings. These issues can all point to foundation movement caused by soil shifts, water damage, or natural wear over time.
At TerraFirma, we’re dedicated to repairing foundations right here in Beaverton with tailored solutions that address the root cause of your foundation issues. Our process starts with a thorough inspection to evaluate the extent and source of the problem, allowing us to recommend the best of our proven foundation repair systems for your needs.
Foundation piers
At our Beaverton location, 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 great in areas with known soil conditions, while push piers are the best choice for places where soil stability is uncertain. Both options 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, ongoing maintenance options, and transferable warranties, so you can feel confident and at ease in your Beaverton home.
Basement Waterproofing Beaverton
When you have a wet basement in Beaverton, it can lead to mold, mildew, structural damage, and poor air quality in your home. Signs of water intrusion may include musty odors, stained walls, standing water, or efflorescence—a white, powdery substance that forms when water evaporates. Even a small crack in your basement wall can become a significant entry point for moisture.
TerraFirma provides top-notch basement waterproofing solutions in Beaverton, ensuring your space stays dry, healthy, and functional—come rain or shine.
Crawl Space Repair Beaverton
Crawl spaces are often forgotten, but they play a vital role in your home’s structure and air quality right here in Beaverton. If left unattended, a neglected crawl space can become a breeding ground for mold, pests, and standing water. These issues can lead to wood rot, unpleasant odors, and even respiratory problems for you and your family.
We understand the crawl space conditions in Beaverton, OR, and TerraFirma’s crawl space repair services are tailored to tackle moisture, mold, pests, and sagging floors with complete 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 Beaverton 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 Beaverton
Cracked, damaged, or uneven concrete isn’t just an 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 Beaverton trust us to swiftly and effectively restore their concrete slabs, sidewalks, patios, and driveways.
TerraFirma provides quick, reliable, and durable concrete leveling and repair services in Beaverton, OR, using state-of-the-art polyurethane foam injection and crack sealing techniques.

- 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.

- Cures in just 60 minutes.

We also provide commercial concrete repair in Beaverton, OR for industrial buildings, warehouse floors, roads, runways, and rail lines—using the same high-quality systems we trust for residential properties.
Earthquake Retrofitting Beaverton, OR
Beaverton and much of the Pacific Northwest are situated in an active seismic zone. Homes built before the updated building codes of the 1990s are particularly at risk. Even a minor earthquake can result in a house shifting off its foundation or facing significant structural damage.
TerraFirma’s earthquake retrofitting services help secure your Beaverton home to its foundation and strengthen its ability to withstand seismic events.
Retrofitting your home for earthquakes in Beaverton can help lower your insurance premiums and deductibles, and may even make you eligible for coverage options that weren’t available before the upgrade.
How We Retrofit
Assessment & Planning
In Beaverton, OR, the retrofitting process starts with a thorough assessment of your building’s current condition. A qualified expert, like a structural engineer or trained technician, will inspect your home to identify any weaknesses and suggest the best solutions.
This evaluation involves a thorough assessment of the foundation, walls, roof, and overall structure. After that, our engineer creates a detailed retrofitting plan tailored to the findings.
Foundation Bolting
Securing the foundation is the next step in the process here in Beaverton. Our technicians will install anchor bolts to firmly connect your home to its foundation, helping to prevent lateral movement in the event of an earthquake.
Our team will drill into your foundation and insert sturdy steel bolts, which are then tightened to reinforce the structure. This process boosts stability and helps protect your home against seismic activity, ensuring peace of mind in Beaverton, OR.
Adding Shear Walls
Shear walls play a vital role in earthquake retrofitting by helping to distribute seismic forces, ensuring that buildings in Beaverton remain secure and stable during an earthquake.
Shear walls, made from sturdy materials like plywood, are strategically installed in key areas of homes, especially in cripple walls. They reinforce the walls, providing extra support and stability to help protect your home during an earthquake.
Bracing & Reinforcing
Next, we’ll strengthen key areas of your Beaverton home with steel braces and straps. Our team installs these sturdy reinforcements on essential structural components like the roof, walls, and floors. This crucial step enhances your home’s stability, creating a robust framework designed to withstand seismic events.
Securing Applicances
Securing your appliances helps create a safer living space for everyone in Beaverton. It’s important to anchor items like water heaters and refrigerators, and our technicians can also install safeguards 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.
