Foundation Repair Dallas
Foundation problems can lead to significant damage to your home if not taken care of. In Dallas, OR, homeowners may see signs like cracks in the floor, bowing walls, and sagging floors, which could indicate deeper structural issues. You might also notice doors that stick, windows that don’t close properly, or gaps between the walls and ceilings. These issues can be signs of a shifting foundation caused by soil movement, water damage, or simply the aging of the home.
At TerraFirma, we provide specialized foundation repair services in Dallas, OR, designed to address the specific causes of your foundation issues. Our process starts with a thorough inspection to evaluate the extent and source of the problem. From there, we recommend one or more of our trusted foundation repair solutions tailored to your needs.
Foundation piers
Our push and helical piers are expertly designed to stabilize and lift your foundation by shifting its load to deeper, more stable soil. Helical piers are ideal for areas with known soil conditions, while push piers are perfect for locations with uncertain soil stability. Both systems are minimally invasive and provide long-lasting solutions for your foundation needs in Dallas, 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, flexible maintenance options, and transferable warranties, ensuring you feel confident and at ease in your Dallas home.
Basement Waterproofing Dallas
Don’t let a wet basement become a problem for your home in Dallas, OR. Moisture can lead to mold, mildew, structural damage, and poor air quality. Look out for signs 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 allow moisture to seep in, so it’s important to address any issues right away.
TerraFirma provides expert basement waterproofing solutions in Dallas, ensuring your space stays dry, healthy, and functional, no matter the weather.
Crawl Space Repair Dallas
Crawl spaces are often forgotten, but they play a vital role in the structure and air quality of your home in Dallas, OR. If ignored, a neglected crawl space can become a breeding ground for mold, pests, and standing water. These problems can lead to wood rot, unpleasant odors, and even respiratory issues for you and your family.
We understand the unique crawl space conditions in Dallas, OR, and TerraFirma’s crawl space repair services are tailored to combat 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 Dallas 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 Dallas
Damaged, cracked, or uneven concrete can be more than just an eyesore—it poses a safety risk, too. These issues often arise from factors like poor soil compaction, freeze-thaw cycles, erosion, or tree root growth. That’s why homeowners in Dallas turn to us for fast and effective solutions to restore their concrete slabs, sidewalks, patios, and driveways.
TerraFirma provides quick, efficient, and durable concrete leveling and repair services in Dallas, OR, utilizing 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 Dallas, 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 Dallas, OR for industrial buildings, warehouse floors, roads, runways, and rail lines—using the same high-quality systems we trust for residential properties.
Earthquake Retrofitting Dallas, OR
Much of the Pacific Northwest, including Dallas, OR, is located in an active seismic zone. Homes built before the updated building codes from the 1990s are particularly at risk. Even a small earthquake can lead to a house shifting off its foundation or suffering significant structural damage.
TerraFirma’s earthquake retrofitting services help secure your Dallas home to its foundation and strengthen its ability to withstand seismic events.
Earthquake retrofitting in Dallas not only strengthens your home but can also help you save on insurance premiums and deductibles, and may even qualify you for coverage that was previously unavailable.
How We Retrofit
Assessment & Planning
The retrofitting process kicks off with a thorough assessment of your building’s current condition. An expert—like a structural engineer or a trained technician—will inspect your home to pinpoint any weaknesses and suggest the best solutions for improvement.
This evaluation involves a thorough inspection of the foundation, walls, roof, and overall structure. Following this, our engineer will create a detailed retrofitting plan tailored to the findings.
Foundation Bolting
Ensuring a solid foundation is the next important step in the process. Our technicians expertly install anchor bolts to firmly connect your home to its foundation, helping to prevent any lateral movement during an earthquake.
In this process, we drill into the foundation and install sturdy steel bolts. Our team then tightens these bolts to reinforce the structure, improving its stability and making it more resilient against seismic activity.
Adding Shear Walls
Shear walls play a vital role in earthquake retrofitting, helping to distribute seismic forces and keep buildings in Dallas, OR, safe from collapse.
Shear walls are usually made of plywood or other durable materials, and our skilled workers strategically install them throughout homes, especially in areas like cripple walls. These walls add crucial support and stability, helping to lower the risk of damage during an earthquake.
Bracing & Reinforcing
Next, we focus on strengthening key areas of your home in Dallas with sturdy steel braces and straps. Our team installs these reinforcements on essential structural elements like the roof, walls, and floors. This crucial step enhances your home’s stability, ensuring it has a resilient framework designed to withstand seismic forces.
Securing Applicances
By securing your appliances, you can create a safer living environment for everyone in your Dallas, OR home. It’s crucial to anchor items like water heaters and refrigerators. Our technicians will also install protective measures for gas meters to help 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.
