Foundation Repair Florence
Foundation issues can lead to significant damage to your home if not taken care of. In Florence, OR, homeowners may notice signs such as floor cracks, bowed walls, or sagging floors, which often indicate deeper structural problems. You might also experience stubborn doors, windows that won’t close properly, or visible gaps between your walls and ceilings. These issues can all point to a shifting foundation caused by soil movement, water damage, or the natural aging of your home.
At TerraFirma, we specialize in foundation repairs in Florence, offering targeted, expert solutions designed to address the specific issues affecting your foundation. Our process starts with a thorough inspection to identify the extent and source of the problem. From there, we recommend one or more of our effective foundation repair systems:
Foundation piers
In Florence, OR, our push and helical piers are expertly designed to stabilize and elevate your foundation by directing its weight to deeper, more stable soil. Helical piers are great for areas with known soil conditions, while push piers excel in places where soil 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, flexible maintenance options, and transferable warranties, so you can feel confident and at ease in your home in Florence.
Basement Waterproofing Florence
Living in Florence, OR, you know how important it is to keep your home safe from the elements. A damp basement can lead to mold, mildew, structural issues, and poor air quality throughout your entire home. You might notice signs of water intrusion such as musty odors, stained walls, pooling water, or even efflorescence—a white, powdery substance that appears when moisture evaporates. Remember, even a tiny crack in your basement wall can allow moisture to seep in and become a bigger problem.
TerraFirma provides top-notch basement waterproofing solutions in Florence that ensure your space stays dry, healthy, and functional—come rain or shine.
Crawl Space Repair Florence
Crawl spaces in Florence are often neglected, but they play a vital role in your home’s structure and air quality. If left unattended, these spaces can become breeding grounds for mold, pests, and standing water. This neglect can result in wood rot, unpleasant odors, and even respiratory problems for those living in the home.
We understand the unique crawl space conditions in Florence, OR, and TerraFirma’s crawl space repair services are tailored to tackle moisture, mold, pests, and sagging floors with comprehensive 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 Florence 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 Florence
Damaged, cracked, or uneven concrete can be more than just an eyesore—it poses a safety risk, too. These issues often arise from poor soil compaction, freeze-thaw cycles, erosion, or tree root growth. Homeowners in Florence count on us for fast and effective solutions to repair their concrete slabs, sidewalks, patios, and driveways.
TerraFirma provides quick, clean, and durable concrete leveling and repair solutions in Florence, OR, utilizing cutting-edge polyurethane foam injection and effective crack sealing methods.
PolyLevel® Concrete Lifting
PolyLevel utilizes expanding polyurethane foam to lift and stabilize concrete slabs. This non-invasive method is perfect for residents of Florence, OR, looking to enhance their driveways, patios, and walkways.
- 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 Florence, OR for industrial buildings, warehouse floors, roads, runways, and rail lines—using the same high-quality systems we trust for residential properties.
Earthquake Retrofitting Florence, OR
Florence, OR, is situated in an active seismic zone, making it important for homeowners to be aware of the potential risks. Homes built before the updated building codes of the 1990s are particularly at risk, as even a minor earthquake can lead to significant foundation shifts or serious structural damage.
TerraFirma’s earthquake retrofitting services help secure your Florence home to its foundation and strengthen its ability to withstand seismic events.
Upgrading your home with earthquake retrofitting in Florence not only enhances safety but can also lower your insurance premiums and deductibles, and may even make you eligible for coverage that wasn’t available before the upgrade.
How We Retrofit
Assessment & Planning
In Florence, the retrofitting process starts with a thorough assessment of your building’s current condition. A qualified expert, like a structural engineer or certified technician, will evaluate your home to pinpoint any weaknesses and suggest the best solutions.
This assessment covers the foundation, walls, roof, and overall structure. After that, our engineer will create a detailed retrofitting plan tailored to the findings.
Foundation Bolting
To ensure your home is well-prepared, securing the foundation is the next important step. Our technicians install anchor bolts that firmly connect your house to its foundation, helping to prevent any lateral movement during an earthquake.
Our process includes carefully drilling holes into the foundation and installing sturdy steel bolts. Our team then tightens these bolts to reinforce the structure, improving its stability and ability to withstand seismic activity.
Adding Shear Walls
Shear walls play a vital role in earthquake retrofitting by helping to distribute seismic forces, ensuring that your home stays safe and sturdy in Florence.
Shear walls, often made from plywood or other durable materials, are strategically placed throughout homes, especially in vulnerable areas like cripple walls. In Florence, OR, these walls enhance your home’s support and stability, helping to minimize the risk of damage during an earthquake.
Bracing & Reinforcing
Next, we enhance the key areas of your home in Florence with sturdy steel braces and straps. Our team carefully installs these to important structural components like the roof, walls, and floors. This step significantly boosts your home’s stability, creating a strong framework designed to withstand seismic forces.
Securing Applicances
By securing your appliances, you can create a safer living environment for everyone in your home. It’s important to anchor essential items like water heaters and refrigerators. Our technicians can also install safety 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.
