Foundation Repair Sandy
Foundation problems can lead to significant damage to your home if not taken care of. If you notice signs like cracks in your floors, bowed walls, or sagging floors, it’s time to take action. Homeowners in Sandy, OR may also experience sticking doors, windows that don’t close right, or visible gaps between walls and ceilings. These issues could indicate that your foundation is shifting due to soil changes, water damage, or simply age. Don’t wait—addressing these concerns early can save you in the long run!
At TerraFirma, we provide specialized foundation repair services in Sandy, offering tailored solutions designed to address the specific issues affecting your home. Our process starts with a thorough inspection to determine the extent and source of the problem. 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 the load to deeper, more stable soil. Helical piers work great in areas with known soil conditions, while push piers are ideal for locations with uncertain soil stability. Both systems are minimally invasive and provide lasting solutions for your foundation needs in Sandy.
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, maintenance options, and transferable warranties, ensuring you have confidence and peace of mind right here in Sandy.
Basement Waterproofing Sandy
Dealing with a wet basement in Sandy, OR? It’s essential to address it quickly, as excess moisture can lead to mold, mildew, and structural damage, plus it can compromise your home’s air quality. Signs of water intrusion might include musty odors, stained walls, pooling water, or a white, powdery residue known as efflorescence left behind when water evaporates. Even a small crack in your basement wall can welcome unwanted moisture, so don’t wait to tackle the issue!
TerraFirma provides top-notch basement waterproofing solutions in Sandy, ensuring your space stays dry, healthy, and functional, whatever the weather brings.
Crawl Space Repair Sandy
Crawl spaces may often be forgotten, but they play a vital role in your home’s structure and air quality here in Sandy, OR. If not properly maintained, these areas can become a breeding ground for mold, pests, and standing water. Ignoring them can lead to problems like wood rot, unpleasant odors, and potential respiratory issues for you and your family.
We understand the unique crawl space conditions in Sandy, OR, and TerraFirma’s crawl space repair services are tailored to tackle issues like moisture, mold, pests, and sagging floors. We offer 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 Sandy 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 Sandy
Damaged, cracked, or uneven concrete isn’t just an eyesore—it can also pose safety risks. Issues like poor soil compaction, freeze-thaw cycles, erosion, and tree root growth can all lead to these problems. That’s why homeowners in Sandy 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 in Sandy, OR, using innovative polyurethane foam injection and expert 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 Sandy, OR
Sandy, OR, is located in a region of the Pacific Northwest that’s known for its seismic activity. Homes built before the updated building codes of the 1990s are particularly at risk. Even a small earthquake can lead to significant issues, like shifting a home off its foundation or causing major structural damage.
TerraFirma’s earthquake retrofitting services help secure your Sandy home to its foundation and strengthen its ability to withstand seismic events.
Retrofitting your home in Sandy for earthquakes not only enhances safety but can also help lower your insurance premiums and deductibles, and may even make you eligible for coverage that wasn’t available before the upgrade.
How We Retrofit
Assessment & Planning
In Sandy, OR, the retrofitting process starts 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 looks at the foundation, walls, roof, and overall structure of your home. After that, our engineer creates a detailed retrofitting plan tailored to the findings.
Foundation Bolting
Securing your foundation is the next crucial step. Our skilled technicians will install anchor bolts to firmly connect your home to its foundation, ensuring it stays in place during an earthquake.
Our approach involves drilling into your home’s foundation and inserting steel bolts. Our skilled team then tightens these bolts to reinforce the structure, improving its stability and making it more resistant to seismic activity.
Adding Shear Walls
In Sandy, OR, shear walls play a vital role in earthquake retrofitting by helping to distribute seismic forces and keeping structures safe from collapse.
Shear walls, often made from durable plywood or other sturdy materials, are strategically installed in homes, especially around vulnerable areas like cripple walls. They enhance the support and stability of your home, helping to minimize the risk of damage during an earthquake.
Bracing & Reinforcing
Next, we focus on strengthening your home’s key areas with steel braces and straps. Our skilled workers install these reinforcements on essential structural components like the roof, walls, and floors. This step boosts your home’s overall stability, creating a robust framework that can better withstand seismic forces common in the Sandy area.
Securing Applicances
By securing your appliances, you can create a safer living space for everyone in Sandy, OR. It’s important to anchor items like water heaters and refrigerators, and our technicians can also install safety 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.
