Foundation Repair Tigard
Foundation issues can lead to significant damage in your home if not taken care of. In Tigard, OR, you might observe symptoms like cracks in the floor, bowing walls, or sagging floors, all of which indicate potential structural problems. Homeowners here may also notice doors sticking, windows that won’t close correctly, or gaps appearing between walls and ceilings. These issues can signal that your foundation is shifting due to factors like soil movement, water damage, or wear and tear over time.
At TerraFirma, we specialize in foundation repair right here in Tigard with precise, expert solutions designed to address the root cause of your foundation issues. Our process starts with a thorough inspection to evaluate the extent and source of the problem. After that, we’ll 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 in Tigard by transferring its weight to deeper, more stable soil layers. Helical piers are perfect for areas with known soil conditions, while push piers are an excellent choice for locations with uncertain soil stability. Both systems are minimally invasive and provide long-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, ensuring you have confidence and peace of mind in your Tigard home.
Basement Waterproofing Tigard
Having a wet basement in Tigard can result in mold, mildew, structural damage, and poor air quality throughout your home. You might notice signs of water intrusion like musty odors, stained walls, pooling water, or efflorescence—a white, powdery residue that appears when water evaporates. Even a tiny crack in your basement wall can open the door for moisture to seep in.
TerraFirma provides top-notch basement waterproofing solutions in Tigard, ensuring your space stays dry, healthy, and functional, no matter the weather.
Crawl Space Repair Tigard
Crawl spaces in Tigard, OR, often go unnoticed, yet they play a vital role in your home’s structure and air quality. If left unmonitored, 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 unique crawl space conditions in Tigard, OR, and TerraFirma’s crawl space repair services are tailored to tackle moisture, mold, pests, and sagging floors with comprehensive encapsulation, effective drainage solutions, 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 Tigard 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 Tigard
Unsightly damaged, cracked, or uneven concrete can create safety risks. Issues like poor soil compaction, freeze-thaw cycles, erosion, or tree root growth can cause these problems. That’s why homeowners in Tigard trust us to quickly and effectively repair their concrete slabs, sidewalks, patios, and driveways.
TerraFirma provides quick, reliable, and durable concrete leveling and repair services in Tigard, OR, using state-of-the-art polyurethane foam injection and crack sealing techniques.
PolyLevel® Concrete Lifting
PolyLevel utilizes expanding polyurethane foam to lift and stabilize concrete slabs. This non-invasive method is perfect for residents of Tigard, 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
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 Tigard, OR for industrial buildings, warehouse floors, roads, runways, and rail lines—using the same high-quality systems we trust for residential properties.

Earthquake Retrofitting Tigard, OR
Much of the Pacific Northwest, including Tigard, is situated in an active seismic zone. Homes built before the updated building codes from the 1990s may be particularly at risk. Even a minor earthquake could cause your home to shift off its foundation or suffer significant structural damage.
TerraFirma’s earthquake retrofitting services help secure your Tigard home to its foundation and strengthen its ability to withstand seismic events.
Enhancing your home with earthquake retrofitting in Tigard not only strengthens your property but can also lower your insurance premiums and deductibles, while making you eligible for coverage that wasn’t available before the upgrade.
How We Retrofit
Assessment & Planning
In Tigard, OR, the retrofitting process kicks off with a comprehensive assessment of your building’s current condition. A qualified expert, like a structural engineer or skilled technician, will carefully inspect your home to pinpoint any weaknesses and suggest the best solutions for improvement.
This evaluation will look at the foundation, walls, roof, and overall structure of your home in Tigard. After that, our engineer will create a detailed retrofitting plan tailored to the findings.
Foundation Bolting
Securing the foundation is a crucial next step in the process. Our skilled technicians install anchor bolts to seamlessly connect your home to its foundation, ensuring stability and preventing any lateral movement during an earthquake.
Our process includes carefully drilling into the foundation and inserting steel bolts. Our team then tightens these bolts to reinforce the structure, improving its stability and resistance to seismic activity right here in Tigard.
Adding Shear Walls
Shear walls play a vital role in earthquake retrofitting here in Tigard, OR, as they help distribute seismic forces, keeping buildings safe and preventing collapses.
Shear walls, made from sturdy materials like plywood, are strategically placed in homes throughout Tigard, especially in areas known as cripple walls. These installations enhance the support and stability of your walls, helping to minimize the risk of damage during an earthquake.
Bracing & Reinforcing
Next, we enhance the strength of your Tigard home by adding steel braces and straps to vital areas. Our team secures these reinforcements to crucial structural components like the roof, walls, and floors. This step significantly boosts your home’s stability, providing a robust framework designed to withstand seismic activity.
Securing Applicances
By securing your appliances, you can create a safer home for you and your family in Tigard. It’s crucial to anchor items like water heaters and refrigerators. Our technicians are also here to install safety measures for gas meters, helping 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.
