Foundation Repair Yachats
Foundation problems can lead to significant damage to your home if not taken care of. In Yachats, OR, homeowners might notice signs like floor cracks, bowing walls, and sagging floors, which can indicate deeper structural issues. You may find that doors are sticking, windows aren’t closing properly, or there are visible gaps between walls and ceilings. These can all be indicators that your foundation is shifting due to soil movement, water damage, or the natural wear and tear that comes with age.
At TerraFirma, we specialize in foundation repairs right here in Yachats. Our targeted and expert solutions are designed to address the specific causes of your foundation issues. We start with a thorough inspection to determine the extent and source of the problem, then we recommend the best proven repair systems to meet your needs:
Foundation piers
In Yachats, our push and helical piers are designed to stabilize and elevate your foundation by shifting its load to deeper, more stable soil layers. Helical piers work best in areas with known soil conditions, while push piers are a great choice when 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, so you can feel confident and secure in your Yachats home.
Basement Waterproofing Yachats
In Yachats, a damp basement can cause serious problems like mold, mildew, structural issues, and poor air quality in your home. You might notice signs of water intrusion such as musty odors, discolored walls, standing water, or a white, powdery residue called efflorescence that appears when water evaporates. Even a tiny crack in your basement wall can turn into a significant pathway for moisture.
TerraFirma provides top-notch basement waterproofing solutions in Yachats, ensuring your space stays dry, healthy, and functional—come rain or shine.
Crawl Space Repair Yachats
Don’t let your crawl space go unnoticed! In Yachats, OR, these often-forgotten areas are vital to your home’s structure and air quality. If left unaddressed, a neglected crawl space can become a breeding ground for mold, pests, and standing water, which can lead to wood rot, unpleasant odors, and even health risks for you and your family.
We understand the unique crawl space conditions in Yachats, OR, and TerraFirma’s crawl space repair services are tailored to tackle moisture, mold, pests, and sagging floors with complete encapsulation, effective drainage solutions, 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 Yachats 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 Yachats
Damaged, cracked, or uneven concrete can be more than just an eyesore—it can pose a real safety risk. These issues can arise from factors like poor soil compaction, freeze-thaw cycles, erosion, or tree root growth. Residents of Yachats trust us to promptly and effectively repair their concrete slabs, sidewalks, patios, and driveways.
At TerraFirma, we provide quick, efficient, and durable concrete leveling and repair solutions for Yachats, OR, utilizing advanced 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 the unique needs of Yachats, OR, including:
- 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 Yachats, OR for industrial buildings, warehouse floors, roads, runways, and rail lines—using the same high-quality systems we trust for residential properties.
Earthquake Retrofitting Yachats, OR
Yachats, OR, is part of an active seismic region in the Pacific Northwest. Homes constructed before the updated building codes of the 1990s may be particularly at risk. Even a small earthquake can lead to shifts in a home’s foundation or serious structural damage.
TerraFirma’s earthquake retrofitting services help secure your Yachats home to its foundation and strengthen its ability to withstand seismic events.
Enhancing your home with earthquake retrofitting in Yachats not only boosts safety but can also lower your insurance premiums and deductibles, and may even open up coverage options that weren’t accessible before the upgrade.
How We Retrofit
Assessment & Planning
In Yachats, the retrofitting process starts with a thorough assessment of your home’s current condition. A qualified expert, like a structural engineer or trained technician, will examine your property 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. After that, our engineer will create a detailed retrofitting plan based on what they discover.
Foundation Bolting
In Yachats, securing your home’s foundation is a crucial step. Our technicians will install anchor bolts to firmly connect your house to its foundation, helping to prevent any lateral movement during an earthquake.
Our process includes drilling into the foundation and carefully inserting steel bolts. Our skilled team then tightens these bolts, reinforcing the structure to improve its stability and better withstand seismic activity.
Adding Shear Walls
Shear walls play a vital role in earthquake retrofitting, helping to distribute seismic forces and keep buildings in Yachats safe from collapse.
Shear walls, often made of plywood or other durable materials, are strategically placed in homes, especially in areas like cripple walls. This added support boosts the stability of your walls, helping to minimize the risk of damage during an earthquake.
Bracing & Reinforcing
Next, we strengthen and protect key areas of your Yachats home with durable steel braces and straps. Our team expertly installs these reinforcements to critical structural elements like the roof, walls, and floors. This process enhances your home’s overall stability, ensuring it has a resilient framework ready to withstand the forces of nature.
Securing Applicances
Securing your appliances can enhance safety for everyone in your Yachats home. It’s important to anchor items like water heaters and refrigerators. Our technicians also provide 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.
