Foundation Repair Arch Cape
Foundation problems can lead to significant damage if not taken care of. Homeowners in Arch Cape, OR may notice signs like cracks in the floors, bowing walls, or sagging floors, which often indicate deeper structural issues. You might find doors sticking, windows not closing properly, or visible gaps between walls and ceilings—these can all signal that your foundation is shifting due to soil movement, water damage, or the natural wear and tear of age.
At TerraFirma, we specialize in foundation repairs in Arch Cape, offering expert solutions that address the specific causes of your foundation issues. Our process starts with a thorough inspection to understand the extent and source of the problem. From there, we recommend one or more of our effective foundation repair systems tailored to your needs:
Foundation piers
In Arch Cape, OR, our push and helical piers are specifically designed to stabilize and elevate your foundation by directing its weight to deeper, more stable soil. Helical piers are ideal for areas with known soil conditions, while push piers are perfect for zones where soil stability is uncertain. Both options offer a minimally invasive solution and provide long-lasting results 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 professional installation, flexible maintenance options, and transferable warranties, providing you with confidence and peace of mind for your home in Arch Cape.
Basement Waterproofing Arch Cape
A damp basement can result in mold, mildew, structural issues, and poor air quality in your home. You might notice signs of water intrusion like musty odors, stained walls, pooling water, or efflorescence—a white, powdery residue left after water evaporates. Even a small crack in your basement wall can become a significant entry point for moisture here in Arch Cape.
At TerraFirma, we provide top-notch basement waterproofing solutions in Arch Cape that ensure your space stays dry, healthy, and functional—regardless of the weather.
Crawl Space Repair Arch Cape
Don’t let your crawl space go unnoticed! In Arch Cape, OR, these underappreciated areas play a vital role in your home’s structure and air quality. When neglected, they can become a breeding ground for mold, pests, and stagnant water. This can lead to wood rot, unpleasant odors, and even health issues for you and your family. It’s time to give your crawl space the attention it deserves!
We understand the unique crawl space conditions in Arch Cape, OR, and TerraFirma’s crawl space repair services are 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 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 Arch Cape 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 Arch Cape
Cracked, damaged, or uneven concrete isn’t just an eyesore—it’s a safety concern. These issues often arise from poor soil compaction, freeze-thaw cycles, erosion, or tree roots. That’s why homeowners in Arch Cape trust us to repair their concrete slabs, sidewalks, patios, and driveways swiftly and effectively.
At TerraFirma, we provide quick, efficient, and durable concrete leveling and repair services for Arch Cape, OR, utilizing cutting-edge polyurethane foam injection and expert crack sealing.
PolyLevel® Concrete Lifting
PolyLevel utilizes expanding polyurethane foam to lift and stabilize concrete slabs. This non-invasive method is perfect for the needs of Arch Cape residents:
- 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 Arch Cape, OR for industrial buildings, warehouse floors, roads, runways, and rail lines—using the same high-quality systems we trust for residential properties.
Earthquake Retrofitting Arch Cape, OR
Arch Cape, OR, is situated in a region known for its seismic activity. Homes constructed before the updated building codes of the 1990s may be particularly at risk. Even a small earthquake can lead to significant shifts in a home’s foundation or serious structural damage.
TerraFirma’s earthquake retrofitting services help secure your Arch Cape home to its foundation and strengthen its ability to withstand seismic events.
Upgrading your home with earthquake retrofitting in Arch Cape can also help lower your insurance premiums and deductibles, plus you may qualify for coverage options that weren’t available before the upgrade.
How We Retrofit
Assessment & Planning
In Arch Cape, the retrofitting process starts with a thorough evaluation of your home’s current condition. A skilled professional, like a structural engineer or trained technician, will examine the property to pinpoint any weaknesses and suggest the best solutions.
Our evaluation looks closely at the foundation, walls, roof, and overall structure of your property. After that, our engineer will create a detailed retrofitting plan tailored to the findings.
Foundation Bolting
Securing your home’s foundation is a crucial step. Our technicians expertly install anchor bolts that connect your house to its foundation, ensuring it stays stable and secure during an earthquake.
In Arch Cape, our team carefully drills into the foundation and installs sturdy steel bolts. By tightening these bolts, we reinforce the structure, boosting its stability and improving its ability to withstand seismic activity.
Adding Shear Walls
Shear walls play an essential role in earthquake retrofitting by evenly distributing seismic forces, helping to keep your Arch Cape home safe and standing strong.
Shear walls are usually made from plywood or other sturdy materials, and they’re strategically placed throughout homes, especially in cripple walls. This added support increases stability and helps reduce the risk of damage during an earthquake, providing peace of mind for Arch Cape residents.
Bracing & Reinforcing
Next, we’ll enhance the critical areas of your Arch Cape home by adding steel braces and straps. Our team expertly installs these reinforcements on key structural elements like the roof, walls, and floors. This important step boosts your home’s overall stability, creating a strong framework designed to withstand seismic forces.
Securing Applicances
Ensuring your appliances are securely anchored helps create a safer living environment for everyone in Arch Cape. It’s important to anchor items like water heaters and refrigerators, and our technicians can also install protective 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.

Arch Cape
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.
