Foundation Repair Marylhurst
Foundation issues can lead to significant damage to your home if not addressed promptly. In Marylhurst, OR, homeowners may observe signs like floor cracks, bowing walls, or sagging floors that indicate deeper structural concerns. You might find that doors are sticking, windows won’t close properly, or there are visible gaps between walls and ceilings. These issues could all be signs of a shifting foundation, often caused by soil movement, water damage, or the natural aging of your home.
At TerraFirma, we specialize in foundation repairs in Marylhurst with customized, expert solutions designed to address the root cause of your foundation issues. Our process starts with a thorough inspection to evaluate the extent and origin of the problem. From there, we recommend one or more of 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 familiar soil conditions, while push piers are the ideal choice for areas with unpredictable soil stability. Both systems are minimally invasive and provide long-lasting solutions.
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 Marylhurst home.
Basement Waterproofing Marylhurst
Dealing with a wet basement in Marylhurst? It can cause mold, mildew, structural issues, and impact the air quality in your home. You might notice signs like musty odors, stained walls, pooling water, or a white, powdery substance called efflorescence left behind as water evaporates. Even a tiny crack in your basement wall can turn into a significant gateway for moisture, so it’s essential to address these issues promptly.
TerraFirma provides cutting-edge basement waterproofing solutions in Marylhurst, ensuring your space stays dry, healthy, and functional—regardless of the weather.
Crawl Space Repair Marylhurst
Crawl spaces are frequently neglected, but they play a vital role in your home’s structure and air quality here in Marylhurst. If not properly maintained, 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 those living in the home.
At TerraFirma, we understand the unique crawl space issues faced in Marylhurst, OR. Our expert crawl space repair services tackle moisture, mold, pests, and sagging floors with comprehensive solutions like full encapsulation, effective drainage, and sturdy 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 Marylhurst 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 Marylhurst
Cracked, damaged, or uneven concrete not only looks unattractive—it poses safety risks as well. These issues often arise from factors like inadequate soil compaction, freeze-thaw cycles, erosion, or even tree roots. In Marylhurst, homeowners rely on us for prompt and effective repairs to their concrete slabs, sidewalks, patios, and driveways.
TerraFirma provides quick, reliable, and durable concrete leveling and repair solutions for Marylhurst, OR, utilizing advanced polyurethane foam injection and crack sealing techniques.

- Sidewalks – Eliminates tripping hazards and restores smooth walkways.
- Driveways – Prevents further cracking and improves curb appeal.

We also provide commercial concrete repair in Marylhurst, OR for industrial buildings, warehouse floors, roads, runways, and rail lines—using the same high-quality systems we trust for residential properties.
Earthquake Retrofitting Marylhurst, OR
Marylhurst, OR, is part of a region known for its seismic activity. If your home was built before the updated building codes of the 1990s, it may be at greater risk. Even a small earthquake can lead to significant shifting or structural damage.
TerraFirma’s earthquake retrofitting services help secure your Marylhurst home to its foundation and strengthen its ability to withstand seismic events.
Retrofitting your home for earthquakes in Marylhurst not only strengthens your property but can also lower your insurance premiums and deductibles, plus help you qualify for coverage that wasn’t available before the upgrade.
How We Retrofit
Assessment & Planning
In Marylhurst, the 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 tailored to your needs.
This evaluation involves inspecting the foundation, walls, roof, and overall structure of your property in Marylhurst. Our engineer will then create a detailed retrofitting plan tailored to the findings.
Foundation Bolting
Strengthening the foundation is the next step in the process. Our technicians install anchor bolts to securely connect your home to its foundation, ensuring it remains stable during an earthquake.
In Marylhurst, we strengthen your home’s foundation by carefully drilling holes and inserting durable steel bolts. Our skilled team tightens these bolts to ensure your structure is more stable and better equipped to withstand seismic activity.
Adding Shear Walls
Shear walls play a vital role in earthquake retrofitting, helping to distribute seismic forces and keep buildings in Marylhurst safe from collapse.
Shear walls, commonly made from plywood or other sturdy materials, are strategically placed throughout homes, especially in areas like cripple walls. They offer extra support and stability, helping to minimize the risk of damage during an earthquake here in Marylhurst.
Bracing & Reinforcing
Next, we’ll enhance the critical areas of your home in Marylhurst with steel braces and straps. Our team installs these to key structural elements like the roof, walls, and floors. This important step boosts your home’s stability, ensuring it has a strong framework that can better withstand seismic forces.
Securing Applicances
By securing your appliances, you can create a safer living environment in Marylhurst, OR. Anchoring items like water heaters and refrigerators is crucial for your home’s safety, and our technicians will also provide protection 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.

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.
