Foundation Repair Gervais
Foundation issues can lead to significant damage to your home if ignored. Homeowners in Gervais, OR might notice signs like cracked floors, bowed walls, and sagging floors, which can indicate deeper structural problems. You might also experience sticky doors, windows that won’t close properly, or gaps appearing between your walls and ceilings. These signs often point to foundation shifts caused by soil movement, water damage, or the natural aging of your home.
At TerraFirma, we provide expert foundation repair solutions right here in Gervais, tailored specifically to address the unique issues affecting your home’s foundation. Our process starts with a thorough inspection to determine the root cause and severity of the problem. After that, we’ll recommend one or more of our trusted foundation repair systems to restore your peace of mind.
Foundation piers
Our push and helical piers are expertly designed to stabilize and lift foundations by transferring weight to deeper, more stable soil layers. Helical piers are great for areas with known soil conditions, while push piers are a reliable choice for spots with uncertain soil stability. Both systems are minimally invasive and provide lasting solutions for your home in Gervais.
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 feel confident and at ease in your Gervais home.
Basement Waterproofing Gervais
Experiencing a wet basement in Gervais can cause mold, mildew, structural damage, and compromise the air quality in your home. You might notice musty odors, stained walls, standing water, or white, powdery substances called efflorescence, which appear when moisture evaporates. Even a tiny crack in your basement wall can turn into a significant source of water intrusion.
TerraFirma provides top-notch basement waterproofing solutions in Gervais to ensure your space stays dry, healthy, and functional, whatever the weather brings.
Crawl Space Repair Gervais
Crawl spaces in Gervais are often overlooked, but they play a vital role in your home’s structure and air quality. When neglected, these areas can become a breeding ground for mold, pests, and standing water. This can lead to wood rot, unpleasant odors, and even respiratory problems for you and your family.
We understand the unique crawl space challenges in Gervais, OR, and TerraFirma’s crawl space repair services are tailored to tackle moisture, mold, pests, and sagging floors. Our approach includes 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 Gervais 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.

Earthquake Retrofitting Gervais, OR
Gervais, OR, is located in an area of the Pacific Northwest that’s prone to seismic activity. Homes constructed before the updated building codes from the 1990s may be particularly at risk. Even a minor earthquake can lead to a house shifting off its foundation or suffering significant structural damage.
TerraFirma’s earthquake retrofitting services help secure your Gervais home to its foundation and strengthen its ability to withstand seismic events.
Upgrading your home with earthquake retrofitting in Gervais can help lower your insurance premiums and deductibles, plus you might qualify for coverage that wasn’t available before the upgrade.
How We Retrofit
Assessment & Planning
In Gervais, the retrofitting process starts with a thorough assessment of your building’s current condition. A qualified professional, like a structural engineer or trained technician, will inspect your home to pinpoint any weaknesses and suggest the best solutions.
This assessment involves inspecting the foundation, walls, roof, and overall structure of your property. Following this, our engineer will create a detailed retrofitting plan tailored to the findings.
Foundation Bolting
Stabilizing the foundation is the next crucial step. Our technicians expertly install anchor bolts that connect your home to its foundation, ensuring it stays secure and reducing the risk of lateral movement in the event of an earthquake.
Our process includes drilling holes into the foundation and installing steel bolts. Our team then tightens these bolts to reinforce the structure, boosting its stability and making it more resilient against seismic events.
Adding Shear Walls
In Gervais, OR, shear walls play a vital role in earthquake retrofitting by helping to distribute seismic forces and keeping structures safe from collapse.
In Gervais, OR, shear walls are usually made from durable plywood or similar materials, and our skilled workers strategically install them in key locations throughout your home, especially in areas like cripple walls. This added support enhances the stability of your walls, helping to minimize the risk of damage during an earthquake.
Bracing & Reinforcing
Next, we strengthen the essential parts of your home in Gervais with robust steel braces and straps. Our team expertly installs these reinforcements on key structural elements like the roof, walls, and floors, enhancing your home’s overall stability. This vital step ensures your home has a solid framework that can effectively withstand seismic forces.
Securing Applicances
By securing your appliances, you can create a safer living space in Gervais, OR. Anchoring items like water heaters and refrigerators is important for your peace of mind. Our technicians will also install protective measures for gas meters, helping 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.
