Foundation Repair Monroe
Foundation issues can lead to significant damage to your home if not addressed promptly. In Monroe, OR, homeowners may notice signs like cracks in the floors, bowing walls, and sagging floors, which often indicate more serious structural problems. You might find doors that stick, windows that won’t close properly, or gaps forming between walls and ceilings. These symptoms could mean that your foundation is shifting due to soil movement, water damage, or natural wear and tear over time.
At TerraFirma, we provide specialized foundation repair services right here in Monroe. Our expert team carefully identifies the root cause of your foundation issues through a thorough inspection. After understanding the extent of the problem, we recommend one or more of our tried-and-true foundation repair solutions tailored to your needs.
Foundation piers
Our push and helical piers are designed to stabilize and lift foundations in Monroe, OR by transferring their load to deeper, more stable soil. Helical piers work best for known soil conditions, while push piers are ideal for areas with uncertain soil stability. Both options are minimally invasive and provide permanent 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 expert installation, ongoing maintenance options, and transferable warranties, ensuring you have confidence and peace of mind in your Monroe home.
Basement Waterproofing Monroe
Experiencing a wet basement in Monroe, OR? It can lead to serious issues like mold, mildew, structural damage, and even affect the air quality in your home. Look out for signs of water intrusion such as musty odors, stained walls, standing water, or efflorescence—a white powdery residue left when water evaporates. Remember, even a small crack in your basement wall can become a big entry point for moisture.
TerraFirma provides top-notch basement waterproofing solutions in Monroe, ensuring your space stays dry, healthy, and functional, come rain or shine.
Crawl Space Repair Monroe
Don’t underestimate the importance of your crawl space in Monroe, OR! It plays a vital role in your home’s structure and air quality. If ignored, it can become a breeding ground for mold, pests, and standing water. These problems might lead to wood rot, unpleasant odors, and even health issues for those living in your home.
We understand the crawl space conditions specific to Monroe, OR, and TerraFirma’s 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 Monroe 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.

Earthquake Retrofitting Monroe, OR
Monroe, OR, is located in an active seismic zone, making it important for homeowners to understand the potential risks. Homes built before the updated building codes of the 1990s are particularly susceptible to damage. Even a minor earthquake can cause a house to shift off its foundation or suffer significant structural issues.
TerraFirma’s earthquake retrofitting services help secure your Monroe home to its foundation and strengthen its ability to withstand seismic events.
Earthquake retrofitting in Monroe not only helps keep your home safe but can also lower your insurance premiums and deductibles, plus it may make you eligible for coverage options that weren’t available before the upgrade.
How We Retrofit
Assessment & Planning
In Monroe, OR, the retrofitting process kicks off with a thorough assessment 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 right solutions.
Our evaluation covers a thorough inspection of the foundation, walls, roof, and overall structure. After that, our engineer will create a detailed retrofitting plan tailored to the findings.
Foundation Bolting
Securing the foundation is the next step in the process here in Monroe, OR. Our technicians will install anchor bolts to firmly connect your home to its foundation, ensuring it remains stable and secure during an earthquake.
Our process involves drilling into the foundation and inserting steel bolts, which are then tightened to secure the structure. This greatly enhances its stability and helps it withstand seismic forces, ensuring your home in Monroe, OR is safe and sound.
Adding Shear Walls
Shear walls play a vital role in earthquake retrofitting in Monroe, OR. They help distribute seismic forces and keep buildings safe from collapsing during tremors.
Shear walls are usually made from plywood or other durable materials and are strategically placed in homes, especially in areas like cripple walls. They offer extra support and stability to your walls, helping to minimize the risk of damage during an earthquake.
Bracing & Reinforcing
Next, we focus on strengthening key areas of your Monroe home with durable steel braces and straps. Our team carefully installs these reinforcements to essential structural elements like the roof, walls, and floors. This important step enhances your home’s stability, ensuring it has a solid framework designed to withstand seismic forces.
Securing Applicances
Securing your appliances can help create a safer home for you and your family here in Monroe, OR. Anchoring essential items like water heaters and refrigerators is key. Our technicians also ensure gas meters are protected to 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.
