Foundation Repair Napavine
Foundation problems can lead to significant damage to your home if not taken care of promptly. If you’re in Napavine, WA, you may start to notice signs like cracks in your floors, bowed walls, or sagging floors—all of which can indicate more serious structural issues. Homeowners here might also experience sticking doors, windows that won’t shut properly, or gaps between walls and ceilings. These could be warning signs that your foundation is shifting, potentially due to soil movement, water damage, or the age of your home.
At TerraFirma, we specialize in foundation repairs right here in Napavine. Our expert solutions are designed specifically for the unique issues affecting your foundation. We start with a thorough inspection to identify the root cause of the problem, and then we recommend one or more of our trusted foundation repair systems tailored to your needs.
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 are perfect for areas with known soil conditions, while push piers work best in places with uncertain soil stability. Both systems are minimally invasive and provide lasting solutions for your home in Napavine.
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 Napavine home.
Basement Waterproofing Napavine
Having a wet basement in Napavine can cause a host of problems, from mold and mildew to structural damage and poor air quality in your home. You might notice signs of water intrusion like musty odors, stained walls, pooling water, or a white powdery residue known as efflorescence that appears when water evaporates. Even a tiny crack in your basement wall can turn into a significant entryway for moisture.
TerraFirma provides cutting-edge basement waterproofing solutions in Napavine, ensuring your space stays dry, healthy, and functional—come rain or shine.
Crawl Space Repair Napavine
Crawl spaces in Napavine may not always be top of mind, but they play a vital role in your home’s structure and air quality. When left neglected, these spaces can become a breeding ground for mold, pests, and standing water. Ignoring them may lead to problems like wood rot, unpleasant odors, and even respiratory issues for your family.
At TerraFirma, we understand the unique crawl space conditions in Napavine, WA. Our specialized crawl space repair services effectively tackle issues like moisture, mold, pests, and sagging floors with comprehensive solutions, including 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 Napavine 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 Napavine
Cracked, damaged, or uneven concrete isn’t just an eyesore—it can also be a safety concern. Issues like poor soil compaction, freeze-thaw cycles, erosion, and tree root growth can lead to these problems. That’s why homeowners in Napavine 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 in Napavine, WA, 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 Napavine, 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 Napavine, WA for industrial buildings, warehouse floors, roads, runways, and rail lines—using the same high-quality systems we trust for residential properties.
Earthquake Retrofitting Napavine, WA
Napavine, WA is located in a region of the Pacific Northwest that is prone to seismic activity. Homes built before the updated building codes of the 1990s may be particularly at risk. Even a small earthquake can lead to homes shifting off their foundations or suffering significant structural damage.
TerraFirma’s earthquake retrofitting services help secure your Napavine home to its foundation and strengthen its ability to withstand seismic events.
Upgrading your home with earthquake retrofitting in Napavine 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
The retrofitting journey starts with a thorough assessment of your building’s current condition. An expert, like a structural engineer or trained technician, will inspect your home in Napavine to pinpoint any weaknesses and suggest the best solutions.
This evaluation looks closely at the foundation, walls, roof, and overall structure. Based on the findings, our engineer will create a detailed retrofitting plan tailored to your needs.
Foundation Bolting
Strengthening the foundation is the next crucial step. Our technicians securely install anchor bolts to connect your home to its foundation, helping to prevent any shifting during an earthquake.
In Napavine, we enhance the stability of your home by drilling holes into the foundation and inserting steel bolts. Our team then tightens these bolts to secure the structure, helping it withstand seismic forces.
Adding Shear Walls
Shear walls play a vital role in earthquake retrofitting by helping to distribute seismic forces, ensuring that buildings in Napavine, WA, remain safe and stable during tremors.
Shear walls are usually made from plywood or other durable materials, and they’re strategically placed throughout homes, especially in areas like cripple walls. This added support enhances the stability of your home, helping to minimize the risk of damage during an earthquake.
Bracing & Reinforcing
Next, we strengthen key areas of your home in Napavine with durable steel braces and straps. Our team carefully installs these reinforcements on essential structural elements like the roof, walls, and floors. This crucial step enhances your home’s overall stability, giving it a robust framework designed to withstand seismic activity.
Securing Applicances
Ensuring your appliances are properly secured helps create a safer living environment in Napavine. Anchoring essential items like water heaters and refrigerators is crucial. Our technicians can also install safety measures 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.
