Foundation Repair Wasco
Foundation problems can lead to significant damage to your home if not taken care of. In Wasco, OR, homeowners may notice signs like cracks in the flooring, bowing walls, or sagging floors. You might also find that doors are sticking, windows won’t close properly, or there are visible gaps between the walls and ceilings. These issues could indicate that your foundation is shifting due to soil movement, water damage, or simply the passage of time.
At TerraFirma, we specialize in foundation repairs right here in Wasco. Our expert team provides tailored solutions that address the unique causes of your foundation issues. We start with a thorough inspection to determine the extent and source of the problem, and then we recommend one or more of our effective foundation repair systems:
Foundation piers
Our push and helical piers are designed to stabilize and lift your foundation by transferring its weight to deeper, more stable soil. Helical piers work best in areas with known soil conditions, while push piers are perfect for spots where soil stability is uncertain. Both options are minimally invasive and provide lasting solutions for your home in Wasco.
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, ongoing maintenance options, and transferable warranties, ensuring you feel confident and at ease in your Wasco home.
Basement Waterproofing Wasco
Dealing with a wet basement in Wasco, OR can bring on a range of issues like mold, mildew, structural damage, and poor air quality in your home. Look out for warning signs such as musty odors, stained walls, standing water, or efflorescence—a white powdery residue that appears when water evaporates. Even a tiny crack in your basement wall can quickly turn into a significant pathway for moisture.
TerraFirma provides top-notch basement waterproofing solutions right here in Wasco, ensuring your space stays dry, healthy, and usable no matter the weather.
Crawl Space Repair Wasco
Crawl spaces in Wasco, OR, are often forgotten, but they play a vital role in your home’s structure and air quality. If left unaddressed, a neglected crawl space can become a haven for mold, pests, and standing water. These issues can result in wood rot, unpleasant smells, and even respiratory problems for your family.
We understand the unique crawl space conditions in Wasco, OR, and TerraFirma’s crawl space repair services are tailored to tackle issues like moisture, mold, pests, and sagging floors with effective solutions such as 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 Wasco 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 Wasco
Damaged, cracked, or uneven concrete can not only be an eyesore but also a safety risk. These issues often arise from factors like poor soil compaction, freeze-thaw cycles, erosion, or tree root expansion. Homeowners in Wasco trust us to quickly and effectively repair their concrete slabs, sidewalks, patios, and driveways.
TerraFirma provides quick, efficient, and durable concrete leveling and repair services for the residents of Wasco, OR, using cutting-edge polyurethane foam injection and expert crack sealing techniques.
PolyLevel® Concrete Lifting
PolyLevel employs expanding polyurethane foam to lift and stabilize concrete slabs. This non-invasive method is perfect for residents of Wasco, 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

- 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.

Earthquake Retrofitting Wasco, OR
In Wasco, Oregon, like many areas in the Pacific Northwest, we live in an active seismic zone. Homes constructed before the updated building codes in the 1990s can be particularly at risk. Even a minor earthquake could potentially shift a home off its foundation or lead to serious structural damage.
TerraFirma’s earthquake retrofitting services help secure your Wasco home to its foundation and strengthen its ability to withstand seismic events.
Retrofitting your home against earthquakes in Wasco can help you lower your insurance premiums and deductibles, and it may even make you eligible for coverage options that were previously unavailable.
How We Retrofit
Assessment & Planning
In Wasco, OR, the retrofitting process starts with a thorough assessment of your building’s condition. A qualified expert, like a structural engineer or trained technician, will inspect your home to pinpoint any weaknesses and suggest the best solutions.
This assessment looks at the foundation, walls, roof, and overall structure. From there, our engineer crafts a detailed retrofitting plan tailored to the findings.
Foundation Bolting
Securing the foundation is the next important step. Our technicians will install anchor bolts to firmly connect your home to its foundation, helping to prevent any shifting during an earthquake.
Our process includes drilling into the foundation and placing steel bolts. Our team then tightens these bolts to strengthen the structure, boosting its stability and resilience against earthquakes.
Adding Shear Walls
Shear walls play a vital role in earthquake retrofitting by helping to distribute seismic forces, ensuring that your building remains safe and stable during an earthquake in Wasco, OR.
Shear walls are usually made from plywood or other sturdy materials, and our skilled team installs them in key areas of your home, especially in cripple walls. This added support enhances stability and helps minimize the risk of damage during an earthquake.
Bracing & Reinforcing
Next, we strengthen the essential areas of your home in Wasco with durable steel braces and straps. Our team expertly installs these reinforcements on key structural elements like the roof, walls, and floors. This vital step enhances your home’s overall stability, creating a robust framework designed to withstand seismic forces.
Securing Applicances
By securing your appliances, you can create a safer living space in Wasco, OR. It’s important to anchor items like water heaters and refrigerators. Our technicians will also install protection 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.

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.
