Foundation Repair Bonney Lake
Foundation problems can lead to significant damage if not taken care of. Homeowners in Bonney Lake, WA, may notice signs like cracks in the floors, bowing walls, or sagging floors, all of which could indicate more serious structural issues. You might also find that doors are sticking, windows won’t close properly, or there are visible gaps between your walls and ceilings. These issues can be signs that your foundation is shifting due to soil movement, water damage, or natural wear over time.
At TerraFirma, we specialize in foundation repair right here in Bonney Lake. Our team provides expert solutions tailored specifically to address the unique causes of your foundation issues. We start with a thorough inspection to evaluate the extent and source of the problem, followed by our recommendation of one or more of our trusted foundation repair systems.
Foundation piers
At Bonney Lake, WA, our push and helical piers are expertly designed to stabilize and elevate your foundation by transferring its weight to deeper, more stable soil. Helical piers work great in familiar soil conditions, while push piers are the ideal choice for areas with uncertain soil stability. Both systems are minimally invasive and provide lasting solutions for your home.
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, ensuring you feel confident and at ease in your Bonney Lake home.
Basement Waterproofing Bonney Lake
Dealing with a wet basement in Bonney Lake? It’s more than just an inconvenience. Excess moisture can lead to mold, mildew, structural damage, and compromised air quality in your home. You might notice signs like musty odors, stained walls, pooling water, or efflorescence—a white, powdery residue left when water evaporates. Even a tiny crack in your basement wall can become a significant entry point for moisture.
TerraFirma provides top-notch basement waterproofing solutions in Bonney Lake, ensuring your space stays dry, healthy, and functional, whatever the weather brings.
Crawl Space Repair Bonney Lake
Don’t underestimate your crawl space—it’s an important part of your home’s structure and air quality here in Bonney Lake. If neglected, it can become a breeding ground for mold, pests, and standing water, leading to wood rot, unpleasant odors, and even health issues for your family. Keep your home safe and healthy by paying attention to this often-overlooked area.
We understand the unique crawl space conditions in Bonney Lake, WA. That’s why TerraFirma offers specialized repair services to tackle moisture, mold, pests, and sagging floors, ensuring your space is fully encapsulated, properly drained, and structurally supported.
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 Bonney Lake 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 Bonney Lake
Damaged, cracked, or uneven concrete isn’t just an eyesore—it’s a safety concern. These issues can arise from factors like poor soil compaction, freeze-thaw cycles, erosion, or tree roots. Homeowners in Bonney Lake trust us to quickly and effectively repair their concrete slabs, sidewalks, patios, and driveways.
TerraFirma provides quick, efficient, and durable concrete leveling and repair solutions for Bonney Lake, WA, utilizing cutting-edge polyurethane foam injection and expert 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.

- Includes color-matched sand for a clean, polished look.

We also provide commercial concrete repair in Bonney Lake, WA for industrial buildings, warehouse floors, roads, runways, and rail lines—using the same high-quality systems we trust for residential properties.
Earthquake Retrofitting Bonney Lake, WA
Bonney Lake, WA, is situated in an active seismic zone of the Pacific Northwest. Homes built before the updated building codes were introduced in the 1990s may be particularly at risk. Even a minor earthquake can lead to a home shifting off its foundation or suffering significant structural damage.
TerraFirma’s earthquake retrofitting services help secure your Bonney Lake home to its foundation and strengthen its ability to withstand seismic events.
Earthquake retrofitting in Bonney Lake not only enhances your home’s safety but can also help lower your insurance premiums and deductibles, potentially opening up new coverage options that weren’t available before the upgrade.
How We Retrofit
Assessment & Planning
The retrofitting process starts with a thorough evaluation of your home’s current condition right here in Bonney Lake. A skilled professional, like a structural engineer or trained technician, will inspect your property to pinpoint any weaknesses and suggest the best solutions.
This assessment involves checking the foundation, walls, roof, and overall structure. After that, our engineer will create a detailed retrofitting plan tailored to the results.
Foundation Bolting
In Bonney Lake, securing your home’s foundation is a crucial step in the process. Our technicians install anchor bolts that connect your house to its foundation, keeping it stable and preventing lateral movement during an earthquake.
Our process includes drilling into the foundation and inserting sturdy steel bolts. Our team then tightens these bolts to strengthen the structure, improving its stability and resilience against seismic activity.
Adding Shear Walls
In Bonney Lake, WA, shear walls play a vital role in earthquake retrofitting by helping to distribute seismic forces and keeping your home safe from collapse.
Shear walls are made from sturdy materials like plywood and are strategically placed throughout homes, especially in cripple walls. This added support enhances the stability of your walls, significantly lowering the risk of damage during an earthquake.
Bracing & Reinforcing
Next, we strengthen key areas of your Bonney Lake home with durable steel braces and straps. Our team expertly installs these reinforcements on essential structural elements like the roof, walls, and floors. This process enhances your home’s overall stability, ensuring it has a robust framework designed to withstand seismic forces.
Securing Applicances
Securing your appliances helps create a safer living space in Bonney Lake. It’s important to anchor items like water heaters and refrigerators to prevent accidents. Our technicians can also install protective measures for gas meters, reducing 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.
