Foundation Repair Lyons
Foundation issues can lead to significant damage to your home if they’re not taken care of. In Lyons, OR, homeowners may notice signs like floor cracks, bowing walls, or sagging floors, which often indicate more serious structural problems. You might also find that doors stick, windows won’t close properly, or there are visible gaps between your walls and ceilings. These issues could be signs of shifting foundations caused by soil movement, water damage, or the natural aging of your home.
At TerraFirma, we provide expert foundation repair services in Lyons, OR, with customized solutions designed to tackle 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 recommend one or more of our effective foundation repair systems:
Foundation piers
In Lyons, OR, our push and helical piers are expertly designed to stabilize and elevate your foundation by redirecting its weight to deeper, more stable soil. Helical piers work best in areas with known soil conditions, while push piers are ideal for regions with unpredictable soil stability. Both systems 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 expert installation, ongoing maintenance options, and transferable warranties, providing you with confidence and peace of mind right here in Lyons.
Basement Waterproofing Lyons
In Lyons, OR, a damp basement can create problems like mold, mildew, structural damage, and poor air quality in your home. You might notice signs of water intrusion such as musty odors, stained walls, standing water, or efflorescence—a white, powdery substance that appears when water evaporates. Even a tiny crack in your basement wall can turn into a significant entry point for moisture.
TerraFirma provides top-notch basement waterproofing solutions in Lyons to ensure your space stays dry, healthy, and functional, no matter the weather.
Crawl Space Repair Lyons
Crawl spaces in Lyons are often ignored, but they play a vital role in your home’s structure and air quality. If neglected, these areas can become havens for mold, pests, and standing water, leading to issues like wood rot, unpleasant odors, and even respiratory problems for your family.
We understand the crawl space conditions in Lyons, OR, and TerraFirma’s crawl space repair services are tailored to tackle moisture, mold, pests, and sagging floors with full encapsulation, drainage solutions, 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 Lyons 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 Lyons
Damaged, cracked, or uneven concrete can be more than just a visual concern—it poses a safety risk too. These issues often arise from factors like poor soil compaction, freeze-thaw cycles, erosion, or tree roots. Residents of Lyons trust us to swiftly and effectively repair their concrete slabs, sidewalks, patios, and driveways.
TerraFirma provides quick, efficient, and durable concrete leveling and repair solutions in Lyons, OR, utilizing state-of-the-art polyurethane foam injection and expert crack sealing.
PolyLevel® Concrete Lifting
PolyLevel utilizes expanding polyurethane foam to lift and stabilize concrete slabs. This non-invasive solution is perfect for the residents of Lyons, OR, looking to:
- 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 Lyons, OR for industrial buildings, warehouse floors, roads, runways, and rail lines—using the same high-quality systems we trust for residential properties.
Earthquake Retrofitting Lyons, OR
In Lyons, OR, many homes are situated in a region prone to seismic activity. Houses built before the updated codes of the 1990s may be at a higher 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 Lyons home to its foundation and strengthen its ability to withstand seismic events.
Upgrading your home with earthquake retrofitting in Lyons not only strengthens its safety but can also lower your insurance premiums and deductibles. Plus, you may qualify for coverage options that weren’t available before the upgrade.
How We Retrofit
Assessment & Planning
In Lyons, OR, the retrofitting process starts with a thorough assessment of your building’s current condition. Our experienced professionals, including structural engineers and trained technicians, will inspect your home to pinpoint any weaknesses and suggest the best solutions.
This evaluation involves assessing the foundation, walls, roof, and overall structure. Following this, the engineer will create a detailed retrofitting plan tailored to the findings.
Foundation Bolting
Strengthening the foundation is the next important step in our process here in Lyons, OR. Our technicians expertly install anchor bolts to firmly connect your home to its foundation, ensuring stability and preventing shifting during an earthquake.
Our process includes carefully drilling into the foundation and placing steel bolts. Our skilled team then tightens these bolts, reinforcing the structure to improve its stability and resilience against seismic activity.
Adding Shear Walls
Shear walls play a vital role in earthquake retrofitting by helping to distribute seismic forces and keep buildings in Lyons, OR, safe from collapse.
Shear walls are usually made of plywood or other durable materials and are strategically installed in key areas of your home, especially in cripple walls. These reinforcements add extra support and stability, helping to protect your home from potential damage during an earthquake.
Bracing & Reinforcing
Next, we strengthen key areas of your home in Lyons with sturdy steel braces and straps. Our team installs these reinforcements on essential structural components like the roof, walls, and floors. This vital step enhances your home’s overall stability, giving it a robust framework designed to withstand seismic forces.
Securing Applicances
Anchoring appliances like water heaters and refrigerators is key to creating a safer living environment in Lyons, OR. Our technicians will also secure gas meters to help 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.
