Foundation Repair Leaburg
Foundation issues can lead to significant damage to your home if not taken care of. Homeowners in Leaburg, OR, might see signs like cracks in the floors, bowing walls, or sagging floors, which could indicate more serious structural problems. You may also notice doors sticking, windows not closing properly, or gaps appearing between walls and ceilings. These issues can all point to foundation shifts caused by soil movement, water damage, or age-related wear and tear.
At TerraFirma, we specialize in repairing foundations in Leaburg with expert solutions designed to address the root causes of your foundation issues. Our process starts with a thorough inspection to determine the extent and source of the problem. From there, we recommend one or more of our effective foundation repair systems:
Foundation piers
Our push and helical piers are designed to stabilize and lift your foundation by shifting its weight to deeper, more reliable soil. Helical piers work best in areas with known soil conditions, while push piers are the go-to choice for unpredictable soil. Both options are minimally invasive and provide lasting solutions right here in Leaburg.
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 feel confident and at ease in your Leaburg home.
Basement Waterproofing Leaburg
In Leaburg, a wet basement can lead to mold, mildew, structural damage, and poor air quality in your home. Look out for musty odors, stained walls, pooling water, or that white, powdery residue known as efflorescence, which appears when water evaporates. Even a tiny crack in your basement wall can open the door for moisture to seep in.
TerraFirma provides top-notch basement waterproofing solutions in Leaburg to ensure your space stays dry, healthy, and functional—whatever the weather brings.
Crawl Space Repair Leaburg
Crawl spaces might not be at the top of your mind, but they play a vital role in your home’s structure and air quality here in Leaburg. If neglected, these areas can become a haven for mold, pests, and standing water, leading to serious issues like wood rot, unpleasant odors, and even respiratory problems for you and your family.
We understand the unique crawl space conditions in Leaburg, OR, and TerraFirma’s repair services are tailored to tackle issues like moisture, mold, pests, and sagging floors with our comprehensive solutions that include 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 Leaburg 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 Leaburg
Damaged, cracked, or uneven concrete can pose safety risks and detract from the beauty of your property. Factors like poor soil compaction, freeze-thaw cycles, erosion, and tree root growth can lead to these issues. Homeowners in Leaburg trust us to quickly and effectively restore their concrete slabs, sidewalks, patios, and driveways.
TerraFirma provides quick, efficient, and durable concrete leveling and repair services in Leaburg, OR, utilizing advanced 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.

Earthquake Retrofitting Leaburg, OR
Leaburg, located in the heart of the Pacific Northwest, sits in an active seismic zone. Homes constructed before the updated building codes of the 1990s may be particularly at risk. Even a small earthquake can lead to significant issues, such as shifting a home off its foundation or causing severe structural damage.
TerraFirma’s earthquake retrofitting services help secure your Leaburg home to its foundation and strengthen its ability to withstand seismic events.
Retrofitting your home for earthquakes in Leaburg not only strengthens your property but can also help lower your insurance premiums and deductibles, plus give you access to coverage options that weren’t available before the upgrade.
How We Retrofit
Assessment & Planning
In Leaburg, OR, the retrofitting process kicks off with a thorough assessment of your building’s current condition. Our experts, including structural engineers and trained technicians, will inspect your home to pinpoint any weaknesses and suggest the best solutions.
This evaluation involves a thorough inspection of the foundation, walls, roof, and overall structure. Afterward, our engineer will create a detailed retrofitting plan tailored to the findings.
Foundation Bolting
Next, we ensure the foundation is secure. Our technicians will install anchor bolts to firmly connect your home to its foundation, keeping it stable and preventing any side-to-side movement during an earthquake.
In Leaburg, our process strengthens your home’s foundation by drilling holes and inserting steel bolts. Our skilled team tightens these bolts to secure the structure, boosting its stability and resistance to seismic activity.
Adding Shear Walls
Shear walls play a vital role in earthquake retrofitting by helping to spread out seismic forces and keeping your home safe from potential collapse.
In Leaburg, OR, shear walls are usually made from plywood or other durable materials. Our skilled workers strategically place them throughout your home, especially in cripple walls, to enhance support and stability. This added reinforcement significantly lowers the risk of damage during an earthquake.
Bracing & Reinforcing
Next, we enhance key areas of your Leaburg home with sturdy steel braces and straps. Our team installs these reinforcements on essential structural elements like the roof, walls, and floors. This crucial step boosts your home’s stability, ensuring it has a robust framework designed to withstand seismic forces.
Securing Applicances
Securing your appliances can help create a safer home in Leaburg. It’s important to anchor items like water heaters and refrigerators. Our technicians also install protective measures for gas meters to 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.
