Foundation Repair Milwaukie
Foundation issues can lead to significant damage to your home if not taken care of. Signs like floor cracks, bowing walls, and sagging floors can indicate more serious structural problems. Residents of Milwaukie, OR, may also notice sticky doors, windows that won’t close properly, or visible gaps between walls and ceilings. These issues may suggest that your foundation is shifting due to soil movement, water damage, or the natural aging process.
At TerraFirma, we specialize in foundation repair in Milwaukie, offering expert solutions designed specifically for the unique issues affecting your home’s foundation. Our process starts with a thorough inspection to identify the root cause of your foundation troubles. From there, we’ll recommend one or more of our trusted foundation repair systems tailored to your needs.
Foundation piers
Our push and helical piers are designed to stabilize and lift your foundation by transferring its weight to deeper, more stable soil layers. Helical piers work great in areas with known soil conditions, while push piers are ideal for spots where soil stability is uncertain. Both methods are minimally invasive and provide lasting solutions for homeowners in Milwaukie.
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, ensuring you have confidence and peace of mind in your Milwaukie home.
Basement Waterproofing Milwaukie
Dealing with a wet basement in Milwaukie? It can lead to mold, mildew, structural issues, and even impact the air quality in your home. Look out for signs like musty odors, stained walls, water pooling, or efflorescence—the white powdery residue left when water evaporates. Remember, even a tiny crack in your basement wall can turn into a significant pathway for moisture.
TerraFirma provides top-notch basement waterproofing solutions in Milwaukie, ensuring your space stays dry, healthy, and functional, no matter what the weather brings.
Crawl Space Repair Milwaukie
Crawl spaces in Milwaukie homes are often forgotten, yet they’re a vital part of your home’s structure and air quality. If neglected, these areas can become breeding grounds for mold, pests, and standing water. This can lead to serious problems like wood rot, unpleasant odors, and even health issues for those living in the house.
We understand the unique crawl space conditions in Milwaukie, OR, and TerraFirma’s crawl space repair services are specifically designed to tackle moisture, mold, pests, and sagging floors through 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 Milwaukie 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 Milwaukie
Cracked, damaged, or uneven concrete isn’t just an eyesore—it can also pose a safety risk. These issues can arise from factors like poor soil compaction, freeze-thaw cycles, erosion, or tree root growth. Homeowners in Milwaukie trust us to promptly and efficiently repair their concrete slabs, sidewalks, patios, and driveways.
At TerraFirma, we provide quick, efficient, and durable concrete leveling and repair solutions for Milwaukie, OR. Our methods utilize advanced polyurethane foam injection and expert crack sealing to get the job done right.
PolyLevel® Concrete Lifting
PolyLevel utilizes expanding polyurethane foam to lift and stabilize concrete slabs. This non-invasive method is perfect for residents of Milwaukie, 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

- 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 Milwaukie, OR for industrial buildings, warehouse floors, roads, runways, and rail lines—using the same high-quality systems we trust for residential properties.
Earthquake Retrofitting Milwaukie, OR
Much of the Pacific Northwest, including Milwaukie, OR, is situated in an active seismic zone. Homes built before the updated building codes of the 1990s may be particularly at risk. Even a small earthquake could cause a house to shift off its foundation or suffer serious structural damage.
TerraFirma’s earthquake retrofitting services help secure your Milwaukie home to its foundation and strengthen its ability to withstand seismic events.
Upgrading your home with earthquake retrofitting in Milwaukie not only strengthens your property’s safety but can also lead to lower insurance premiums and deductibles, and may even open up coverage options that weren’t available before the upgrade.
How We Retrofit
Assessment & Planning
In Milwaukie, OR, our 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 assessment involves a thorough inspection of the foundation, walls, roof, and overall structure. Following this, our engineer will create a detailed retrofitting plan tailored to the findings.
Foundation Bolting
The next step in the process is securing the foundation. Our technicians in Milwaukie will install anchor bolts to firmly connect your home to its foundation, ensuring it stays resilient against lateral movement during an earthquake.
Our process begins by drilling into the foundation and installing steel bolts, which our team tightens to reinforce the structure. This not only improves stability but also boosts its resistance to seismic activity, keeping homes in Milwaukie safe and secure.
Adding Shear Walls
Shear walls play a vital role in earthquake retrofitting by evenly distributing seismic forces, helping to keep structures in Milwaukie safe and standing strong.
Shear walls, made of plywood or other durable materials, are strategically installed in homes around Milwaukie, especially in areas like cripple walls. They offer extra support and stability, helping to minimize the risk of damage during an earthquake.
Bracing & Reinforcing
Next, we’ll enhance your home’s stability by adding steel braces and straps to key structural areas like the roof, walls, and floors. This important step fortifies your home’s framework, ensuring it can better withstand seismic forces and providing you with peace of mind.
Securing Applicances
By securing your appliances, you can create a safer living space in Milwaukie. It’s important to anchor items like water heaters and refrigerators. Our technicians will also install protective measures for 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.
