Foundation Repair Gearhart
Foundation issues can lead to significant damage to your home if not addressed in time. Residents of Gearhart, OR may notice warning signs like floor cracks, bowing walls, or sagging floors—each of which could indicate deeper structural problems. You might also experience doors that stick, windows that struggle to close, or visible gaps between your walls and ceilings. These symptoms can all point to a shifting foundation caused by soil movement, water damage, or natural aging.
At TerraFirma, we provide specialized foundation repair services in Gearhart, tailored to address the specific issues affecting your home. Our process starts with a thorough inspection to identify the root cause of your foundation problems. From there, we recommend one or more of our effective foundation repair solutions designed to restore your peace of mind:
Foundation piers
In Gearhart, OR, our push and helical piers are expertly designed to stabilize and elevate your foundation by redistributing its weight to deeper, more reliable soil. Helical piers are great for areas with established soil conditions, while push piers are suited for locations where ground stability is uncertain. Both options 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 have confidence and peace of mind in your Gearhart home.
Basement Waterproofing Gearhart
Experiencing a wet basement in Gearhart, OR? Don’t let it turn into a bigger problem! Excess moisture can lead to mold, mildew, structural issues, and poor air quality in your home. Look for signs like musty odors, stained walls, standing water, or even efflorescence—the white, powdery residue that appears when water evaporates. Remember, even a tiny crack in your basement wall can become a gateway for unwanted moisture.
TerraFirma provides top-notch basement waterproofing solutions in Gearhart, ensuring your space stays dry, healthy, and functional, regardless of the weather.
Crawl Space Repair Gearhart
Crawl spaces may not be top of mind, but they play an essential role in your home’s structure and air quality here in Gearhart. If left unattended, these often-overlooked areas can trap mold, attract pests, and collect standing water. This can lead to wood rot, unpleasant odors, and even respiratory problems for those living in your home.
We understand the unique crawl space conditions in Gearhart, OR, and TerraFirma’s repair services are specifically designed to tackle moisture, mold, pests, and sagging floors. Our solutions include complete encapsulation, efficient 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 Gearhart 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 Gearhart
Cracked, damaged, or uneven concrete isn’t just an eyesore—it’s a safety concern. Issues can arise from factors like poor soil compaction, freeze-thaw cycles, erosion, or tree root growth. Residents of Gearhart trust us to promptly and effectively repair their concrete slabs, sidewalks, patios, and driveways.
In Gearhart, OR, TerraFirma provides quick, efficient, and durable concrete leveling and repair with our state-of-the-art polyurethane foam injection and crack sealing techniques.

- 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.

- 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 Gearhart, OR for industrial buildings, warehouse floors, roads, runways, and rail lines—using the same high-quality systems we trust for residential properties.
Earthquake Retrofitting Gearhart, OR
Gearhart, OR, like much of the Pacific Northwest, is located in an active seismic zone. Homes built before the updated building codes introduced in the 1990s may be 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 Gearhart home to its foundation and strengthen its ability to withstand seismic events.
Earthquake retrofitting in Gearhart not only helps protect your home but can also lower your insurance premiums and deductibles, and may even make you eligible for coverage options that weren’t available before the upgrade.
How We Retrofit
Assessment & Planning
In Gearhart, OR, the retrofitting process starts with a thorough evaluation of your home’s current condition. Our experienced professionals, including structural engineers and trained technicians, will assess your property to pinpoint any weaknesses and suggest the best solutions.
This assessment looks closely at the foundation, walls, roof, and overall structure. Based on the findings, the engineer will create a detailed retrofitting plan tailored to your needs.
Foundation Bolting
Taking the next step in this process involves securing the foundation. Our technicians install anchor bolts to safely connect your home to its foundation, helping to prevent any lateral movement during an earthquake here in Gearhart.
Our process involves drilling into the foundation and inserting steel bolts. Our team tightens these bolts to reinforce the structure, boosting its stability and resistance to seismic activity right here in Gearhart.
Adding Shear Walls
Shear walls play a vital role in earthquake retrofitting by helping to distribute seismic forces and safeguard structures from collapsing, making them an essential feature in Gearhart, OR.
In Gearhart, OR, shear walls are usually made from plywood or other sturdy materials, thoughtfully placed in key areas of your home, especially in cripple walls. These installations offer extra support and stability, helping to minimize the risk of damage during an earthquake.
Bracing & Reinforcing
Next, we’ll fortify your home by adding steel braces and straps to essential areas. Our team installs these to key structural components like the roof, walls, and floors. This step enhances your home’s overall stability, providing a strong framework designed to withstand seismic forces—perfect for Gearhart’s unique coastal environment.
Securing Applicances
Ensuring that your appliances are securely anchored can make your home in Gearhart safer for everyone. It’s essential to stabilize items like water heaters and refrigerators. Our technicians can also install protective measures 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.
