Foundation Repair Carlton
Foundation issues can lead to significant damage to your home if not taken care of. In Carlton, OR, you might notice signs like cracks in the floor, bowing walls, or sagging floors, which often indicate more serious structural problems. Homeowners may also experience sticking doors, windows that won’t close properly, or gaps appearing between walls and ceilings. These symptoms could be a sign that your foundation is shifting due to soil movement, water damage, or simply the effects of aging.
At TerraFirma, we provide specialized foundation repair services in Carlton, addressing the unique issues affecting your home’s foundation. We start with a thorough inspection to identify the root cause of the problem, ensuring our solutions are tailored to your specific needs. After that, we’ll recommend the best options from our trusted 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. Helical piers work best in areas with known soil conditions, while push piers are the ideal choice for locations with uncertain soil stability. Both systems are minimally invasive and provide lasting solutions for your home in Carlton.
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 includes professional installation, flexible maintenance plans, and transferable warranties, ensuring you feel confident and at ease in your Carlton home.
Basement Waterproofing Carlton
Dealing with a wet basement in Carlton, OR? It can lead to mold, mildew, structural issues, and poor air quality in your home. Look out for warning signs like musty odors, stained walls, pooling water, or that white, powdery substance known as efflorescence, which appears when water evaporates. Even a small crack in your basement wall can let in a lot of moisture.
TerraFirma provides top-notch basement waterproofing solutions in Carlton to ensure your space stays dry, healthy, and functional—come rain or shine.
Crawl Space Repair Carlton
Crawl spaces in Carlton are often forgotten, yet they play a vital role in your home’s structure and air quality. If left unattended, a neglected crawl space can become a breeding ground for mold, pests, and standing water. These issues can result in wood rot, unpleasant odors, and even respiratory problems for your family.
We understand the unique crawl space conditions in Carlton, OR, and TerraFirma’s repair services are tailored to tackle moisture, mold, pests, and sagging floors. Our comprehensive solutions include full encapsulation, effective drainage, and robust 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 Carlton 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 Carlton
Damaged, cracked, or uneven concrete isn’t just an eyesore; it’s a safety concern. Issues like poor soil compaction, freeze-thaw cycles, erosion, and tree root growth can cause these problems. Homeowners in Carlton trust us to quickly and effectively repair their concrete slabs, sidewalks, patios, and driveways.
TerraFirma provides quick, reliable, and durable concrete leveling and repair services for Carlton, OR, utilizing cutting-edge polyurethane foam injection and expert crack sealing.

Earthquake Retrofitting Carlton, OR
Carlton, OR, is situated in a region known for seismic activity. Homes built before the 1990s, when updated building codes were introduced, may be particularly at risk. Even a small earthquake can cause a home to shift from its foundation or suffer significant structural damage.
TerraFirma’s earthquake retrofitting services help secure your Carlton home to its foundation and strengthen its ability to withstand seismic events.
Earthquake retrofitting in Carlton can help reduce your insurance premiums and deductibles, and it may even qualify you for coverage that was previously unavailable.
How We Retrofit
Assessment & Planning
In Carlton, OR, the retrofitting process starts with a thorough evaluation of your building’s current condition. A skilled expert, like a structural engineer or trained technician, will inspect your home to pinpoint any weaknesses and suggest the best solutions to enhance its safety and durability.
This assessment looks closely at the foundation, walls, roof, and overall structure. Afterward, our engineer will create a detailed retrofitting plan tailored to the findings.
Foundation Bolting
Choosing the right foundation is crucial for your home in Carlton, OR. Our technicians install anchor bolts to securely connect your house to its foundation, ensuring it stays stable and safe during an earthquake.
In Carlton, OR, we enhance your home’s stability by drilling into the foundation and securely installing steel bolts. Once tightened, these bolts provide added strength and resilience against seismic forces, ensuring your structure stands strong.
Adding Shear Walls
Shear walls are an essential part of earthquake retrofitting in Carlton, OR, as they help distribute seismic forces and keep buildings from collapsing.
In Carlton, OR, shear walls are usually made from plywood or other durable materials, strategically placed within homes, especially in areas like cripple walls. These walls offer added support and stability, helping to minimize the risk of structural failure during an earthquake.
Bracing & Reinforcing
Next, we strengthen key areas of your home in Carlton with durable steel braces and straps. Our team installs these on important structural components such as the roof, walls, and floors. This crucial step enhances your home’s overall stability, ensuring it has a robust framework that can withstand seismic forces.
Securing Applicances
Securing your appliances can help create a safer living environment for everyone in your Carlton home. It’s important to anchor items like water heaters and refrigerators, and our technicians also install safety measures for gas meters 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.
