Foundation Repair Graham
Foundation issues can lead to major problems for your home if they’re not taken care of. If you notice things like cracks in your floors, bowing walls, or sagging floors, these could be warning signs of more serious structural concerns. Residents of Graham, WA might also see doors that stick, windows that don’t close right, or gaps appearing between walls and ceilings. These signs often indicate that your foundation may be shifting due to soil movement, water damage, or the natural aging process of your home.
At TerraFirma, we specialize in foundation repairs right here in Graham, WA, offering expert solutions designed specifically for the unique causes of your foundation issues. Our process starts with a detailed inspection to determine the extent and source of the problem. From there, we’ll recommend one or more of our reliable foundation repair systems:
Foundation piers
In Graham, WA, our push and helical piers are designed to strengthen and elevate your foundation by shifting its weight to deeper, more stable soil. Helical piers work best in areas with predictable soil conditions, while push piers are ideal for locations where soil stability is uncertain. Both options are minimally invasive and provide lasting 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 feel confident and at ease in your home in Graham.
Basement Waterproofing Graham
Are you dealing with a damp basement in Graham, WA? It could lead to serious issues like mold, mildew, structural damage, and poor air quality in your home. Look out for signs of water intrusion, such as musty odors, discolored walls, standing water, or a white, powdery residue known as efflorescence that appears when water evaporates. Remember, even a small crack in your basement wall can let in a significant amount of moisture.
TerraFirma provides top-notch basement waterproofing solutions right here in Graham, ensuring your space stays dry, healthy, and functional—whatever the weather brings.
Crawl Space Repair Graham
Crawl spaces in Graham may often be forgotten, but they’re vital for 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 lead to wood rot, unpleasant odors, and even respiratory problems for those living in your home.
At TerraFirma, we understand the unique crawl space conditions in Graham, WA. That’s why our dedicated repair services tackle moisture, mold, pests, and sagging floors with comprehensive solutions like 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 Graham 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 Graham
Cracked, damaged, or uneven concrete isn’t just an eyesore—it can also pose safety risks. These issues often arise from poor soil compaction, freeze-thaw cycles, erosion, or tree roots. Thankfully, homeowners in Graham rely on us to swiftly and effectively repair their concrete slabs, sidewalks, patios, and driveways.
TerraFirma provides quick, effective, and durable concrete leveling and repair solutions in Graham, WA, using cutting-edge polyurethane foam injection and crack sealing.

- 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.

- Cures in just 60 minutes.
- Withstands extreme weather and heavy use.
- Includes color-matched sand for a clean, polished look.

Earthquake Retrofitting Graham, WA
Graham, WA, is located in a region of the Pacific Northwest that’s prone to earthquakes. Homes built before the updated building codes of the 1990s may be at higher risk. Even a small quake can cause significant problems, such as shifting a home off its foundation or leading to serious structural damage.
TerraFirma’s earthquake retrofitting services help secure your Graham home to its foundation and strengthen its ability to withstand seismic events.
Retrofitting your home for earthquakes in Graham not only strengthens your property but can also help lower your insurance premiums and deductibles, plus you may qualify for coverage that wasn’t available before the upgrade.
How We Retrofit
Assessment & Planning
In Graham, WA, the retrofitting process starts with a thorough assessment of your building’s current state. An expert, like a structural engineer or a trained technician, will inspect your home to pinpoint any weaknesses and suggest effective solutions.
This evaluation involves 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
In Graham, WA, the next important step is securing your home’s foundation. Our skilled technicians will install anchor bolts that connect the house to its foundation, ensuring stability and preventing movement during an earthquake.
In Graham, WA, we strengthen your home by drilling into the foundation and installing sturdy steel bolts. Our team tightens these bolts to reinforce the structure, improving its stability and ability to withstand seismic activity.
Adding Shear Walls
Shear walls play a vital role in earthquake retrofitting in Graham, WA, as they help evenly distribute seismic forces and keep structures from collapsing.
Shear walls, usually made from plywood or other sturdy materials, are carefully placed throughout your home, especially in areas with cripple walls. These additions give your walls extra support and stability, helping to lower the risk of damage during an earthquake.
Bracing & Reinforcing
Next, we’ll enhance key areas of your home in Graham by adding steel braces and straps. Our team installs these reinforcements on vital structural components like the roof, walls, and floors. This crucial step boosts your home’s stability, creating a robust framework that can better handle seismic forces.
Securing Applicances
By securing your appliances, you can create a safer living environment in Graham, WA. It’s important to anchor items like water heaters and refrigerators. Our technicians can also install safeguards for gas meters to help 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.
