Foundation Repair Cathlamet
Foundation problems can lead to significant damage to your home if not taken care of. In Cathlamet, WA, homeowners may spot signs like cracks in the floor, walls that bow, or floors that sag—indicators of more serious structural issues. You might also notice doors that stick, windows that don’t close correctly, or gaps between your walls and ceilings. These issues can often point to a shifting foundation caused by soil movement, water damage, or the natural aging of your home.
At TerraFirma, we provide expert foundation repair services right here in Cathlamet. Our team focuses on tailored solutions that address the specific causes of your foundation issues. We start with a thorough inspection to evaluate the extent and source of the problem, and then recommend the best foundation repair systems to meet your needs.
Foundation piers
Our push and helical piers are designed to stabilize and elevate your foundation by transferring its weight to deeper, more stable soil. Helical piers work best in known soil conditions, while push piers are great for areas where soil stability is uncertain. Both systems are minimally invasive and provide lasting solutions for your home in Cathlamet.
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 feel confident and at ease in your Cathlamet home.
Basement Waterproofing Cathlamet
In Cathlamet, WA, a wet basement can cause serious issues like mold, mildew, structural damage, and decreased air quality in your home. Look out for signs of water intrusion, such as musty odors, stained walls, puddles, or efflorescence—a white, powdery residue that appears when water evaporates. Even a small crack in your basement wall can turn into a major pathway for moisture.
TerraFirma provides top-notch basement waterproofing solutions in Cathlamet, ensuring your space stays dry, healthy, and functional no matter the weather.
Crawl Space Repair Cathlamet
Crawl spaces in Cathlamet are often forgotten, but they play a vital role in the structure and air quality of your home. If left unchecked, these hidden areas can become breeding grounds for mold, pests, and standing water. This can lead to wood rot, unpleasant odors, and even health issues for you and your family.
We understand the unique crawl space conditions in Cathlamet, WA. That’s why TerraFirma offers tailored crawl space repair services to tackle moisture, mold, pests, and sagging floors, using 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 Cathlamet 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 Cathlamet
Damaged, cracked, or uneven concrete isn’t just an eyesore—it can also pose a safety risk. These issues often arise from poor soil compaction, freeze-thaw cycles, erosion, or tree roots. Homeowners in Cathlamet count on us to repair their concrete slabs, sidewalks, patios, and driveways quickly and efficiently.
TerraFirma provides quick, efficient, and durable concrete leveling and repair solutions in Cathlamet, WA, using cutting-edge polyurethane foam injection and crack sealing technology.
PolyLevel® Concrete Lifting
PolyLevel utilizes expanding polyurethane foam to lift and stabilize concrete slabs. This non-invasive solution is perfect for residents of Cathlamet, 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 Cathlamet, WA for industrial buildings, warehouse floors, roads, runways, and rail lines—using the same high-quality systems we trust for residential properties.
Earthquake Retrofitting Cathlamet, WA
Living in Cathlamet, WA means being in an area known for its seismic activity. Homes built before the 1990s, when updated building codes were introduced, are particularly at risk. Even a small earthquake can lead to your home shifting off its foundation or suffering serious structural issues.
TerraFirma’s earthquake retrofitting services help secure your Cathlamet home to its foundation and strengthen its ability to withstand seismic events.
Upgrading your home with earthquake retrofitting in Cathlamet not only enhances safety but can also help lower your insurance premiums and deductibles, and may even open the door to coverage options that weren’t available before the upgrade.
How We Retrofit
Assessment & Planning
In Cathlamet, the retrofitting process starts with a thorough assessment of your building’s current condition. A qualified expert, like a structural engineer or skilled technician, will inspect your home to pinpoint any weaknesses and suggest the best solutions.
This evaluation involves checking the foundation, walls, roof, and overall structure. From there, the engineer creates a detailed retrofitting plan tailored to the findings.
Foundation Bolting
Next up is securing the foundation! Our technicians will install anchor bolts to firmly connect your home to its foundation, helping to prevent any shifting during an earthquake.
This process includes drilling into the foundation and installing steel bolts. The team then secures the bolts, boosting the structure’s stability and making it more resistant to seismic activity.
Adding Shear Walls
Shear walls play an essential role in earthquake retrofitting in Cathlamet, WA, helping to distribute seismic forces and keep structures safe from collapse.
Shear walls, often made from plywood or other sturdy materials, are strategically installed throughout homes in Cathlamet, especially in cripple walls. These walls enhance support and stability, helping to minimize the risk of damage during an earthquake.
Bracing & Reinforcing
Next, we strengthen key areas of your home in Cathlamet with sturdy 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, ensuring it’s built to withstand seismic forces.
Securing Applicances
Installing secure appliances is key to creating a safer living space in Cathlamet. Anchoring essential items like water heaters and refrigerators is crucial, and our technicians will also ensure your gas meters are protected to help reduce the risk of 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.
