Foundation Repair Days Creek
Foundation issues can lead to significant damage to your home if not taken care of promptly. Signs like floor cracks, bowing walls, and sagging floors may indicate more serious structural problems. Residents of Days Creek, OR, might find that doors are sticking, windows are difficult to close, or there are noticeable gaps between the walls and ceilings. These could all be signs that your foundation is shifting due to soil movement, water damage, or age-related wear and tear.
At TerraFirma, we provide expert foundation repair solutions right here in Days Creek. Our approach starts with a thorough inspection to identify the cause and extent of your foundation issues. Based on our findings, we’ll recommend the most effective 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. In Days Creek, OR, helical piers work best for areas with known soil conditions, while push piers are ideal for places where soil stability is uncertain. 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 expert installation, ongoing maintenance options, and transferable warranties, ensuring your confidence and peace of mind right here in your Days Creek home.
Basement Waterproofing Days Creek
Don’t let a wet basement in Days Creek lead to problems like mold, mildew, 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 powdery substance called efflorescence, which appears when water evaporates. Remember, even a small crack in your basement wall can turn into a significant entry point for moisture.
TerraFirma provides top-notch basement waterproofing solutions in Days Creek that ensure your space stays dry, healthy, and functional, come rain or shine.
Crawl Space Repair Days Creek
Crawl spaces in Days Creek are often forgotten, but they play a vital role in your home’s structure and air quality. If ignored, these areas can collect moisture, harbor pests, and even develop mold. Such problems can lead to wood rot, unpleasant odors, and respiratory issues for you and your family.
We understand the unique conditions of crawl spaces in Days Creek, OR, and our TerraFirma crawl space repair services are tailored to tackle moisture, mold, pests, and sagging floors with comprehensive solutions like full encapsulation, effective drainage, and reliable 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 Days Creek 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 Days Creek
Cracked, damaged, or uneven concrete isn’t just an eyesore—it can also pose a safety risk. These issues can arise from factors like poor soil compaction, freeze-thaw cycles, erosion, or tree root growth. That’s why homeowners in Days Creek count on us to swiftly and effectively repair their concrete slabs, sidewalks, patios, and driveways.
TerraFirma provides quick, reliable, and durable concrete leveling and repair services right here in Days Creek, OR, utilizing cutting-edge polyurethane foam injection and expert crack sealing techniques.
PolyLevel® Concrete Lifting
PolyLevel uses expanding polyurethane foam to lift and stabilize concrete slabs. This non-invasive method is perfect for residents of Days Creek, 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

Earthquake Retrofitting Days Creek, OR
Days Creek, OR, is located in an active seismic area of the Pacific Northwest. Homes built before the updated building codes of the 1990s may be at higher risk. Even a small earthquake can lead to significant structural issues or shift a home off its foundation.
TerraFirma’s earthquake retrofitting services help secure your Days Creek home to its foundation and strengthen its ability to withstand seismic events.
Upgrading your home with earthquake retrofitting in Days Creek can not only enhance your safety but also help lower your insurance premiums and deductibles, and may even make you eligible for coverage options that weren’t available before.
How We Retrofit
Assessment & Planning
In Days Creek, OR, the retrofitting process starts with a thorough assessment of your building’s current condition. An expert—like a structural engineer or trained technician—will inspect your home, pinpoint any weaknesses, and suggest the best solutions to enhance its strength and safety.
This evaluation looks at the foundation, walls, roof, and overall structure of your property here in Days Creek. After that, our engineer will create a detailed retrofitting plan tailored to the findings.
Foundation Bolting
Securing the foundation is the next crucial step. Our local technicians in Days Creek install anchor bolts to firmly connect your home to its foundation, helping to prevent any sideways movement during an earthquake.
In Days Creek, OR, we enhance the stability of your home by drilling holes into the foundation and inserting steel bolts. Our team then tightens the bolts to secure the structure, improving its resistance to seismic forces.
Adding Shear Walls
Shear walls play a vital role in earthquake retrofitting in Days Creek, OR, helping to distribute seismic forces and keep buildings safe from collapse.
In Days Creek, OR, shear walls are often made from plywood or other sturdy materials, strategically placed in key areas of homes, especially in cripple walls. These walls offer added support and stability, helping to reduce the risk of damage during an earthquake.
Bracing & Reinforcing
Next, we reinforce the important areas of your home in Days Creek with durable steel braces and straps. Our team installs these on vital structural elements like the roof, walls, and floors. This crucial step enhances your home’s stability, ensuring it has a strong framework capable of withstanding seismic forces.
Securing Applicances
Securing appliances can help create a safer living environment for everyone in Days Creek, OR. It’s important to anchor items like water heaters and refrigerators, and our technicians can also install protective measures for gas meters to 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.
