Foundation Repair Gresham
Foundation issues can lead to significant damage to your home if not taken care of promptly. Signs like cracked floors, bowing walls, and sagging floors often indicate deeper structural problems. Residents of Gresham, OR might find that doors stick, windows don’t close properly, or there are noticeable gaps between walls and ceilings. These could all be red flags that your foundation is shifting due to soil movement, water damage, or natural wear and tear over time.
At TerraFirma, we provide expert foundation repair services in Gresham, addressing the specific issues affecting your home’s foundation. Our process starts with a thorough inspection to determine the root cause of the problem. From there, we’ll suggest one or more of our reliable foundation repair solutions tailored to your needs:
Foundation piers
In Gresham, OR, our push and helical piers are expertly designed to stabilize and lift your foundation by transferring its weight to deeper, more stable soil layers. Helical piers work wonders for established soil conditions, while push piers are a great choice for areas with uncertain soil stability. Both options are minimally invasive and provide long-lasting solutions for your home.
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 Gresham home.
Basement Waterproofing Gresham
Dealing with a wet basement in Gresham? It can lead to mold, mildew, structural issues, and worsen the air quality in your home. Signs of water intrusion might include musty odors, discolored walls, standing water, or efflorescence—a chalky substance left behind when water evaporates. Even a tiny crack in your basement wall can turn into a big entryway for moisture.
TerraFirma provides top-notch basement waterproofing solutions in Gresham to ensure your space stays dry, healthy, and functional—rain or shine.
Crawl Space Repair Gresham
Crawl spaces may not be the first thing on your mind, but they’re an essential part of your home’s structure and air quality right here in Gresham. If neglected, these areas can become a breeding ground for mold, pests, and standing water. Over time, these problems can cause wood rot, unpleasant odors, and even respiratory issues for you and your family.
We understand the crawl space conditions in Gresham, OR, and TerraFirma’s repair services are specifically tailored to tackle issues like moisture, mold, pests, and sagging floors. Our solutions include full encapsulation, effective drainage, and robust structural support.
Encapsulation & Drainage
We begin by sealing the crawl space with our Vapor Barrier, 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.
- Crawl Space 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 Gresham 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 Basement Air 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 Gresham
Damaged, cracked, or uneven concrete isn’t just an eyesore—it can pose serious safety risks. Issues like poor soil compaction, freeze-thaw cycles, erosion, or tree root growth can lead to these problems. That’s why homeowners in Gresham trust us to repair their concrete slabs, sidewalks, patios, and driveways quickly and efficiently.
TerraFirma provides Gresham residents with quick, seamless, and durable concrete leveling and repair services, utilizing cutting-edge polyurethane foam injection and expert crack sealing.
PolyLevel® Concrete Lifting
PolyLevel uses expanding polyurethane foam to lift and stabilize concrete slabs. This non-invasive method is perfect for Gresham homeowners with:
- 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 Gresham, OR for industrial buildings, warehouse floors, roads, runways, and rail lines—using the same high-quality systems we trust for residential properties.
Earthquake Retrofitting Gresham, OR
In Gresham, OR, we’re located in an area prone to seismic activity, and homes built before the updated building codes of the 1990s may be particularly at risk. Even a minor earthquake can lead to your home shifting off its foundation or suffering significant structural damage.
TerraFirma’s earthquake retrofitting services help secure your Gresham home to its foundation and strengthen its ability to withstand seismic events.
Upgrading your home with earthquake retrofitting in Gresham can lower your insurance premiums and deductibles, and may even give you access to coverage options that you couldn’t get before.
How We Retrofit
Assessment & Planning
In Gresham, OR, the retrofitting process starts with a thorough assessment of your building’s current condition. A trained technician or structural engineer will carefully inspect your home to pinpoint any weaknesses and suggest the best solutions to enhance its safety and efficiency.
This assessment involves a thorough inspection of the foundation, walls, roof, and overall structure. Based on the results, the engineer will create a detailed retrofitting plan tailored to your needs.
Foundation Bolting
In Gresham, OR, securing your home’s foundation is an important next step. Our technicians install anchor bolts to firmly connect your house to its foundation, helping to prevent lateral movement during an earthquake.
Our process begins by drilling into the foundation and inserting sturdy steel bolts. Our team then tightens these bolts to reinforce the structure, improving its stability and making it more resilient against seismic activity.
Adding Shear Walls
In Gresham, OR, shear walls play a vital role in earthquake retrofitting by evenly distributing seismic forces and helping to keep buildings standing strong during an earthquake.
Shear walls are usually made of plywood or other sturdy materials, strategically placed throughout homes, especially in cripple walls. These essential supports enhance the stability of your home, helping to reduce the risk of damage during an earthquake—a crucial consideration here in Gresham, OR.
Bracing & Reinforcing
Next, we enhance your home’s resilience by installing steel braces and straps in key areas. Our team secures these elements to essential parts of your home, including the roof, walls, and floors. This step boosts your home’s overall stability, creating a strong framework designed to withstand seismic activity.
Securing Appliances
By securing your appliances, you can create a safer living space for everyone in your 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.
Repairing 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?
Our heavy-duty wall vapor barrier system is better for weeping walls than other commonly used vapor barriers. This Class 1 vapor barrier 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 Grated Trench 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 Basement Drainage System and Perimeter Drainage System 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.
