Foundation Repair Lebanon
Foundation issues can lead to significant damage to your home if not taken care of. Signs like floor cracks, bowing walls, and sagging floors may indicate more serious structural problems. Homeowners in Lebanon, OR may also encounter sticking doors, windows that won’t close properly, or visible gaps between walls and ceilings. These issues can all point to a shifting foundation caused by soil movement, water damage, or the natural wear and tear of age.
At TerraFirma, we specialize in foundation repairs in Lebanon, OR, with expert solutions designed to address the root cause of your foundation issues. Our process starts with a thorough inspection to evaluate the extent and source of the problem. From there, we’ll recommend one or more of our effective foundation repair systems tailored to your needs.
Foundation piers
Our push and helical piers are designed to stabilize and lift your foundation by transferring its weight to deeper, more stable soil. Helical piers work well in known soil conditions, while push piers are ideal for areas with uncertain stability. Both options are minimally invasive and provide lasting solutions for your foundation needs in Lebanon, OR.
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, ensuring you have confidence and peace of mind in your Lebanon home.
Basement Waterproofing Lebanon
Experiencing a wet basement in Lebanon, OR? It can lead to mold, mildew, structural damage, and poor air quality in your home. You might notice signs like musty odors, stained walls, pooling water, or a white, powdery substance known as efflorescence, which appears when water evaporates. Even a tiny crack in your basement wall can become a significant entry point for moisture.
TerraFirma provides top-notch basement waterproofing solutions in Lebanon, ensuring your space stays dry, healthy, and functional—rain or shine.
Crawl Space Repair Lebanon
Crawl spaces may not be top of mind, but they play a vital role in your home’s structure and air quality here in Lebanon, OR. When neglected, these spaces can become a breeding ground for mold, pests, and standing water. This can lead to issues like wood rot, unpleasant odors, and even respiratory problems for those living in your home.
We understand the unique crawl space conditions in Lebanon, OR, and TerraFirma’s crawl space repair services are specifically designed to tackle moisture, mold, pests, and sagging floors. Our solutions include full encapsulation, effective drainage, and reliable structural support.
Encapsulation & Drainage
We begin by sealing the crawl space with our Vapor Barrier, 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.
- Crawl Space 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 Lebanon 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 Basement 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 Lebanon
Unsightly and unsafe, damaged, cracked, or uneven concrete can pose serious risks. Issues like poor soil compaction, freeze-thaw cycles, erosion, or tree root growth can lead to these problems. That’s why homeowners in Lebanon turn to us for fast and effective solutions for their concrete slabs, sidewalks, patios, and driveways.
TerraFirma provides quick, efficient, and durable concrete leveling and repair services for Lebanon, OR, using cutting-edge polyurethane foam injection and crack sealing techniques.

- Driveways – Prevents further cracking and improves curb appeal.

Earthquake Retrofitting Lebanon, OR
Lebanon, OR, is located in a region of the Pacific Northwest that sits within an active seismic zone. Homes constructed prior to the updated building codes of the 1990s are particularly at risk. Even a minor earthquake could lead to your home shifting off its foundation or sustaining significant structural damage.
TerraFirma’s earthquake retrofitting services help secure your Lebanon home to its foundation and strengthen its ability to withstand seismic events.
Upgrading your home with earthquake retrofitting in Lebanon not only enhances safety but can also help lower your insurance premiums and deductibles, making it easier to qualify for coverage that wasn’t available before.
How We Retrofit
Assessment & Planning
In Lebanon, OR, the retrofitting process starts with a thorough assessment of your building’s current condition. An expert, like a structural engineer or a trained technician, will inspect your home to pinpoint any weaknesses and suggest the best solutions.
Our evaluation involves a thorough inspection of the foundation, walls, roof, and overall structure. From there, our engineer creates a detailed retrofitting plan tailored to the findings.
Foundation Bolting
Securing the foundation is a crucial next step in the process here in Lebanon, OR. Our technicians install anchor bolts to firmly connect your home to its foundation, helping to prevent any sideways movement during an earthquake.
Our process starts by drilling holes into your foundation and inserting sturdy steel bolts. Our skilled team then tightens these bolts to reinforce your structure, boosting its stability and improving its resistance to seismic activity here in Lebanon, OR.
Adding Shear Walls
In Lebanon, OR, shear walls play an essential role in earthquake retrofitting by helping to distribute seismic forces and keep structures standing strong during quakes.
Shear walls, often made from plywood or other sturdy materials, are installed in key areas of your home, especially in cripple walls. They add crucial support and stability, helping to minimize the risk of damage during an earthquake.
Bracing & Reinforcing
Next, we strengthen key areas of your Lebanon home with sturdy steel braces and straps. Our team carefully installs these reinforcements to vital structural elements like the roof, walls, and floors. This important step enhances your home’s overall stability, ensuring it has a solid framework that can stand up to seismic forces.
Securing Applicances
By securing your appliances, you can create a safer home in Lebanon, OR. It’s important to anchor items like water heaters and refrigerators. Our technicians can 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.

Lebanon
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 Vapor Barrier 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 Grated Trench 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 Basement Drainage System and Perimeter Drainage System 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.
