Foundation Repair Grants Pass
Foundation problems can lead to significant damage to your home if not taken care of. If you’re in Grants Pass, OR, you might see signs like cracks in your floors, walls that are bowing, or floors that are sagging. Homeowners here often notice doors that stick, windows that don’t close right, or gaps forming between walls and ceilings. These issues can indicate that your foundation is shifting, possibly due to soil movement, water damage, or simply the effects of time.
At TerraFirma, we specialize in foundation repair right here in Grants Pass, offering expert solutions designed to address the specific issues affecting your foundation. Our process starts with a thorough inspection to identify the root cause of the problem. After that, we’ll recommend one or more of our trusted foundation repair systems to get your home back on solid ground.
Foundation piers
Our push and helical piers are designed to stabilize and elevate your foundation by shifting its weight to deeper, more reliable soil. Helical piers work great for known soil conditions in Grants Pass, while push piers are ideal for areas with unpredictable soil stability. Both solutions are minimally invasive and provide lasting support.
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, flexible maintenance options, and transferable warranties, ensuring that you have confidence and peace of mind in your home in Grants Pass.
Basement Waterproofing Grants Pass
Don’t let a damp basement become a problem in Grants Pass! It can cause mold, mildew, structural damage, and affect the air quality in your home. Look out for signs like musty odors, stained walls, pooling water, or efflorescence—a white, powdery substance that appears when water evaporates. Even a tiny crack in your basement wall can turn into a major pathway for moisture. Stay ahead of the issue and protect your home!
TerraFirma provides top-notch basement waterproofing solutions in Grants Pass to ensure your space stays dry, healthy, and functional—whatever the weather brings.
Crawl Space Repair Grants Pass
Crawl spaces might not get much attention, but they play a vital role in your home’s structure and air quality here in Grants Pass. When neglected, they can become a breeding ground for mold, pests, and standing water. These problems can lead to wood rot, unpleasant odors, and even respiratory issues for those living in your home.
We understand the unique crawl space conditions in Grants Pass, OR, and TerraFirma’s crawl space repair services are tailored to tackle moisture, mold, pests, and sagging floors with our comprehensive solutions, including full encapsulation, drainage, and 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 Grants Pass 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 Grants Pass
Cracked, damaged, or uneven concrete isn’t just an eyesore—it can also pose a safety risk. These issues often arise from factors like soil compaction, freeze-thaw cycles, erosion, or tree roots. That’s why homeowners in Grants Pass trust us to restore their concrete slabs, sidewalks, patios, and driveways efficiently and effectively.
At TerraFirma in Grants Pass, we provide quick, reliable, and durable concrete leveling and repair services using state-of-the-art polyurethane foam injection and crack sealing.
PolyLevel® Concrete Lifting
PolyLevel utilizes expanding polyurethane foam to lift and stabilize concrete slabs right here in Grants Pass, OR. This non-invasive method is perfect for:
- 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 Grants Pass, OR for industrial buildings, warehouse floors, roads, runways, and rail lines—using the same high-quality systems we trust for residential properties.
Earthquake Retrofitting Grants Pass, OR
Grants Pass is located in an area of the Pacific Northwest that experiences seismic activity. Homes built before the updated building codes of the 1990s are particularly at risk. Even a small earthquake could potentially shift a house off its foundation or lead to significant structural damage.
TerraFirma’s earthquake retrofitting services help secure your Grants Pass home to its foundation and strengthen its ability to withstand seismic events.
Earthquake retrofitting in Grants Pass can help lower your insurance premiums and deductibles, plus it may qualify you for coverage options that weren’t available before the upgrade.
How We Retrofit
Assessment & Planning
In Grants Pass, the retrofitting process kicks off with a thorough evaluation of your building’s current condition. An experienced professional, like a structural engineer or qualified technician, will inspect your home to pinpoint any weaknesses and suggest the best solutions.
This evaluation involves a thorough examination of the foundation, walls, roof, and overall structure of your home. Based on the findings, our engineer will create a tailored retrofitting plan to ensure your property is safe and strong.
Foundation Bolting
Securing the foundation is the next crucial step in our process. Our experienced technicians install anchor bolts to firmly connect your house to its foundation, ensuring stability and preventing lateral movement during an earthquake – a vital safeguard for Grants Pass homes.
Our process includes drilling into the foundation and inserting steel bolts. Once installed, our team tightens these bolts to reinforce the structure, boosting its stability and making it more resistant to seismic activity.
Adding Shear Walls
Shear walls play a vital role in earthquake retrofitting by redistributing seismic forces, helping to protect structures in Grants Pass from collapse.
Shear walls are usually made from plywood or other sturdy materials, and they’re carefully placed in key areas of your home, especially in cripple walls. These walls offer extra support and stability, helping to minimize the risk of damage during an earthquake—important for our community here in Grants Pass, OR.
Bracing & Reinforcing
Next, we enhance key areas of your home in Grants Pass with durable steel braces and straps. Our team carefully installs these to important structural parts like the roof, walls, and floors. This step boosts your home’s stability, providing a strong framework designed to withstand seismic forces.
Securing Applicances
Securing your appliances can make your home safer for everyone in Grants Pass. Anchoring essential items like water heaters and refrigerators is key to preventing accidents. Our technicians will also install safeguards 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.

Grants Pass
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.
