Foundation Repair Centralia
Foundation problems can lead to significant damage to your home if they’re not taken care of. In Centralia, WA, you might see signs like cracks in your floors, walls that bow, or floors that sag—these often indicate deeper structural issues. Homeowners may also notice sticking doors, windows that won’t close, or gaps between walls and ceilings. All of these could be signs that your foundation is shifting due to soil changes, water damage, or simply the aging of your home.
At TerraFirma, we specialize in foundation repairs right here in Centralia, offering expert solutions designed specifically for the unique issues affecting your home. Our process starts with a thorough inspection to identify the extent and source of any foundation problems. From there, we recommend one or more of our trusted foundation repair systems tailored to meet your needs.
Foundation piers
In Centralia, our push and helical piers are specially designed to stabilize and lift your foundation by transferring its weight to deeper, more stable soil. Helical piers are great for areas with familiar soil conditions, while push piers are the best choice for locations with uncertain soil stability. Both systems 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 professional installation, ongoing maintenance options, and transferable warranties, ensuring you feel confident and at ease in your Centralia home.
Basement Waterproofing Centralia
Dealing with a damp basement in Centralia? It can lead to mold, mildew, structural issues, and poor air quality in your home. You might notice 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 transform into a significant entry point for moisture.
TerraFirma provides top-notch basement waterproofing solutions in Centralia, ensuring your home stays dry, healthy, and functional all year round, no matter the weather.
Crawl Space Repair Centralia
Crawl spaces often get the short end of the stick, but they play a vital role in the structure of your home and the quality of air you breathe. If left unattended, a neglected crawl space in Centralia can become a breeding ground for mold, pests, and standing water. These issues can lead to wood rot, unpleasant odors, and even health concerns for you and your family.
At TerraFirma, we understand the unique crawl space challenges in Centralia, WA. Our expert repair services 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 Centralia 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 Centralia
Cracked, damaged, or uneven concrete not only looks unappealing, but it can also pose a safety risk. These issues often arise from factors like poor soil compaction, freeze-thaw cycles, erosion, or tree root growth. Homeowners in Centralia rely on us to efficiently and effectively repair their concrete slabs, sidewalks, patios, and driveways.
TerraFirma provides quick, efficient, and durable concrete leveling and repair services right here in Centralia, WA, utilizing cutting-edge polyurethane foam injection and expert crack sealing.
PolyLevel® Concrete Lifting
PolyLevel uses expanding polyurethane foam to lift and stabilize concrete slabs. This non-invasive method is perfect for residents of Centralia, WA, 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 Centralia, WA for industrial buildings, warehouse floors, roads, runways, and rail lines—using the same high-quality systems we trust for residential properties.
Earthquake Retrofitting Centralia, WA
Here in Centralia, WA, we’re located in a region that sits within an active seismic zone of the Pacific Northwest. Homes built before the updated building codes of the 1990s are particularly at risk. Even a small earthquake can lead to a home shifting off its foundation or suffering significant structural damage.
TerraFirma’s earthquake retrofitting services help secure your Centralia home to its foundation and strengthen its ability to withstand seismic events.
Retrofitting your home for earthquakes in Centralia can help lower your insurance premiums and deductibles, plus it may even make you eligible for coverage options that weren’t available before the upgrade.
How We Retrofit
Assessment & Planning
In Centralia, WA, the retrofitting process starts with a thorough assessment of your building’s current condition. A qualified expert—whether 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. Afterward, the engineer creates a detailed retrofitting plan based on what they discover.
Foundation Bolting
The next step in the process is securing the foundation. Our skilled technicians install anchor bolts to connect your home to its foundation, helping to prevent lateral movement during an earthquake, so you can feel safe and secure in Centralia.
In Centralia, we enhance your building’s stability and resistance to seismic forces by drilling into the foundation and installing steel bolts. Our team carefully tightens these bolts to ensure your structure is securely anchored.
Adding Shear Walls
Shear walls play a vital role in earthquake retrofitting here in Centralia, helping to distribute seismic forces and keep our buildings safe from collapse.
In Centralia, WA, shear walls are usually made from plywood or other sturdy materials, and they’re installed in key areas of your home, especially in cripple walls. These walls offer extra support and stability, helping to minimize the risk of damage during an earthquake.
Bracing & Reinforcing
Next, we’ll be bracing and reinforcing key areas of your home with durable steel braces and straps. Our team installs these essential supports on important structural elements like the roof, walls, and floors. This step significantly enhances your home’s stability, ensuring it has a strong framework that can hold up against seismic forces.
Securing Applicances
Ensuring your appliances are secured helps create a safer living environment in Centralia. It’s important to anchor items like water heaters and refrigerators. Our technicians can also install protection 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.

Centralia
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.
