Foundation Repair Sweet Home
Foundation issues can lead to significant damage to your home if not taken care of. Signs like cracked floors, bowing walls, and sagging floors often indicate more serious structural concerns. Residents of Sweet Home, OR, might experience problems like sticking doors, windows that won’t close properly, or noticeable gaps between walls and ceilings. These issues could 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 Sweet Home, providing expert solutions designed specifically for the unique needs of your home. Our process starts with a thorough inspection to identify the extent and source of the issue. From there, we’ll recommend one or more of our reliable foundation repair systems:
Foundation piers
Our push and helical piers are designed to stabilize and lift your foundation by transferring its weight to deeper, more stable soil. In Sweet Home, OR, helical piers work great for areas with known soil conditions, while push piers are the ideal choice for spots where soil stability is uncertain. Both solutions are minimally invasive and provide a long-lasting fix for your foundation concerns.
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 Sweet Home home.
Basement Waterproofing Sweet Home
Having a wet basement in Sweet Home can cause issues like mold, mildew, structural problems, and bad air quality in your home. You might notice signs of water intrusion such as musty odors, stained walls, puddles, or a white, powdery substance called efflorescence that develops when water evaporates. Remember, even the tiniest crack in your basement wall can turn into a big entry point for moisture.
TerraFirma provides cutting-edge basement waterproofing solutions in Sweet Home, ensuring your space stays dry, healthy, and functional—come rain or shine.
Crawl Space Repair Sweet Home
“Don’t overlook your crawl space—it plays a vital role in your home’s structure and air quality here in Sweet Home. If neglected, it can become a breeding ground for mold, pests, and standing water, leading to wood rot, unpleasant odors, and even respiratory problems for you and your family.”
We understand the unique crawl space conditions in Sweet Home, OR, and TerraFirma’s expert crawl space repair services are tailored to tackle moisture, mold, pests, and sagging floors with our comprehensive solutions, including 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 Sweet Home 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 Sweet Home
Cracked, damaged, or uneven concrete isn’t just an eyesore—it can also pose safety risks. These issues often arise from poor soil compaction, freeze-thaw cycles, erosion, or tree roots. Homeowners in Sweet Home trust us to swiftly and effectively repair their concrete slabs, sidewalks, patios, and driveways.
At TerraFirma, we provide fast, clean, and durable concrete leveling and repair solutions right here in Sweet Home, OR, using advanced polyurethane foam injection and expert crack sealing techniques.
PolyLevel® Concrete Lifting
PolyLevel employs expanding polyurethane foam to lift and stabilize concrete slabs. This non-invasive method is perfect for Sweet Home, OR residents 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 Sweet Home, OR for industrial buildings, warehouse floors, roads, runways, and rail lines—using the same high-quality systems we trust for residential properties.
Earthquake Retrofitting Sweet Home, OR
Sweet Home, OR, is part of the Pacific Northwest, which is known for its seismic activity. Homes constructed before the updated building codes of the 1990s are particularly at risk. Even a small earthquake can lead to a home shifting off its foundation or suffering significant structural damage.
TerraFirma’s earthquake retrofitting services help secure your Sweet Home home to its foundation and strengthen its ability to withstand seismic events.
By retrofitting your home in Sweet Home for earthquakes, you can enjoy the added advantage of lower insurance premiums and deductibles, plus qualify for coverage that may have been out of reach before the upgrade.
How We Retrofit
Assessment & Planning
In Sweet Home, OR, our retrofitting process kicks off with a thorough evaluation of your building’s current condition. A qualified expert, like a structural engineer or trained technician, 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 creates a detailed retrofitting plan tailored to the findings.
Foundation Bolting
Securing the foundation is a crucial next step in the process. Our technicians install anchor bolts to firmly connect your home to its foundation, helping to prevent any shifting during an earthquake.
In Sweet Home, we strengthen your home’s foundation by carefully drilling holes and inserting durable steel bolts. Our skilled team then tightens these bolts, ensuring your structure is stable and better equipped to withstand seismic activity.
Adding Shear Walls
Shear walls play an essential role in earthquake retrofitting in Sweet Home, OR, helping to distribute seismic forces and keep your home safe from collapsing.
Shear walls are usually made from plywood or other sturdy materials, and our skilled team installs them in key areas of your home, especially in cripple walls. These walls offer extra support and stability, helping to minimize the risk of damage during an earthquake, ensuring your Sweet Home residence remains safe and secure.
Bracing & Reinforcing
Next, we enhance critical areas of your home in Sweet Home with sturdy steel braces and straps. Our team installs these to key structural elements like the roof, walls, and floors. This vital step boosts your home’s overall stability, creating a resilient framework designed to withstand seismic forces.
Securing Applicances
By securing your appliances, you can create a safer living space for everyone in Sweet Home. It’s important to anchor items like water heaters and refrigerators. Our technicians can also install protective 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.
