Foundation Repair Otis
Foundation issues can lead to significant damage to your home if not taken care of. In Otis, OR, homeowners might notice signs like cracked floors, bowing walls, and sagging floors, which often indicate more serious structural problems. You may also experience issues with doors sticking, windows that don’t close properly, or gaps forming between walls and ceilings. These symptoms could point to foundation shifts caused by soil movement, water damage, or natural aging.
At TerraFirma, we specialize in repairing foundations in Otis with customized, expert solutions designed to address the root cause of your foundation issues. Our process starts with a thorough inspection to identify the extent and source of the problem. Following that, we provide recommendations for our reliable foundation repair systems:
Foundation piers
In Otis, OR, our push and helical piers are designed to stabilize and lift your foundation by shifting its weight onto deeper, more stable soil. Helical piers work best in areas with known soil conditions, while push piers are the right choice for locations with uncertain 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 professional installation, ongoing maintenance options, and transferable warranties, so you can feel confident and at ease in your home in Otis.
Basement Waterproofing Otis
Are you dealing with a damp basement in Otis, OR? It can lead to mold, mildew, structural problems, and poor air quality in your home. Look out for musty odors, stained walls, pooling water, or efflorescence—a white powdery residue that appears when water evaporates. Even a tiny crack in your basement wall could become a gateway for moisture.
TerraFirma provides top-notch basement waterproofing solutions in Otis, ensuring your space stays dry, healthy, and usable—rain or shine.
Crawl Space Repair Otis
Crawl spaces are frequently neglected, but they play a vital role in the structure and air quality of your home here in Otis, OR. If left unattended, a forgotten crawl space can become a breeding ground for mold, pests, and stagnant water. These issues can result in wood rot, unpleasant odors, and potential respiratory problems for those living in the home.
We understand the unique crawl space conditions in Otis, OR, and TerraFirma’s crawl space repair services are tailored to tackle moisture, mold, pests, and sagging floors with comprehensive 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 Otis 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 Otis
Cracked or uneven concrete can be more than just an eyesore—it poses safety risks, too. Issues like poor soil compaction, freeze-thaw cycles, erosion, or tree roots can lead to these problems. That’s why homeowners in Otis trust us to repair their concrete slabs, sidewalks, patios, and driveways quickly and reliably.
TerraFirma provides quick, efficient, and durable concrete leveling and repair services in Otis, OR. Our advanced polyurethane foam injection and crack sealing techniques ensure your surfaces are fixed right the first time.
PolyLevel® Concrete Lifting
PolyLevel uses expanding polyurethane foam to lift and stabilize concrete slabs right here in Otis, 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 Otis, OR for industrial buildings, warehouse floors, roads, runways, and rail lines—using the same high-quality systems we trust for residential properties.
Earthquake Retrofitting Otis, OR
Otis, OR, is located in a region of the Pacific Northwest that’s prone to seismic activity. Homes built before the updated codes from the 1990s may be particularly at risk. Even a small earthquake can lead to shifts in a home’s foundation or significant structural damage.
TerraFirma’s earthquake retrofitting services help secure your Otis home to its foundation and strengthen its ability to withstand seismic events.
Enhancing your home with earthquake retrofitting in Otis not only strengthens its safety but can also lower your insurance premiums and deductibles, and open up new coverage options that weren’t available before the upgrade.
How We Retrofit
Assessment & Planning
In Otis, 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 assessment looks at the foundation, walls, roof, and entire structure. Afterward, our engineer creates a detailed retrofitting plan tailored to the results.
Foundation Bolting
Securing the foundation is a crucial next step here in Otis. Our technicians will install anchor bolts to firmly connect your home to its foundation, helping to prevent any shifting during an earthquake.
We drill into the foundation and insert strong steel bolts, then tighten them to reinforce the structure, boosting its stability and making it more resilient against seismic activity.
Adding Shear Walls
In Otis, OR, shear walls play a vital role in earthquake retrofitting by helping to distribute seismic forces and keeping buildings safe from collapse.
In Otis, OR, shear walls are often made from durable plywood or other sturdy materials, strategically placed throughout homes, especially in cripple walls. These walls offer essential support and stability, helping to minimize the risk of damage during an earthquake.
Bracing & Reinforcing
Next, we focus on strengthening essential areas of your home in Otis with steel braces and straps. Our team carefully installs these reinforcements on crucial structural components like the roof, walls, and floors. This step enhances the stability of your home, creating a strong framework that can better withstand seismic forces.
Securing Applicances
Securing your appliances can help create a safer home for everyone in Otis. It’s important to anchor items like water heaters and refrigerators, and our technicians can also install protection 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.
