Foundation issues can lead to significant damage to your home if they’re not taken care of. In Eatonville, WA, you might notice signs like cracks in your floors, bowed walls, or sagging floors, which could indicate deeper structural problems. Homeowners here may also observe sticky doors, windows that won’t close right, or noticeable gaps between the walls and ceilings. These issues can all point to a shifting foundation caused by soil movement, water damage, or just the natural wear and tear over time.
At TerraFirma, we specialize in foundation repairs in Eatonville, offering tailored and expert solutions designed to address the root cause of your foundation issues. Our process starts with a thorough inspection to determine the extent and source of the problem. From there, we recommend one or more of our trusted foundation repair systems to restore your home.
Foundation piers
In Eatonville, WA, our push and helical piers are expertly designed to stabilize and lift your foundation by transferring its weight to deeper, more reliable soil.

- CarbonArmor®: Made from fiber-reinforced polymers ten times stronger than steel.

Earthquake Retrofitting Eatonville, WA
Eatonville and much of the Pacific Northwest sit in an active seismic zone. Homes built before the updated building codes introduced in the 1990s are particularly at risk. Even a minor earthquake can lead to a house shifting off its foundation or suffering significant structural damage.
TerraFirma’s earthquake retrofitting services help secure your Eatonville home to its foundation and strengthen its ability to withstand seismic events.
By retrofitting your home for earthquakes in Eatonville, you can enjoy lower insurance premiums and deductibles, plus access coverage options that may not have been available before.
How We Retrofit
Assessment & Planning
In Eatonville, WA, our retrofitting process starts with a thorough assessment of your building’s current state. A skilled expert, like a structural engineer or trained technician, will carefully inspect your home to pinpoint any weaknesses and suggest the best solutions.
This evaluation involves inspecting the foundation, walls, roof, and overall structure of your home. After that, our engineer will create a detailed retrofitting plan based on what they discover.
Foundation Bolting
The next step in ensuring your home’s safety in Eatonville is securing the foundation. Our skilled technicians will install anchor bolts to firmly connect your house to its foundation, keeping it stable and preventing any lateral movement in the event of an earthquake.
This process includes drilling into the foundation and inserting strong steel bolts. Our team then tightens these bolts to reinforce the structure, boosting its stability and making it more resilient against seismic activity.
Adding Shear Walls
In Eatonville, WA, shear walls play a vital role in earthquake retrofitting by helping to distribute seismic forces, ensuring your home remains safe and stable during an earthquake.
In Eatonville, shear walls are usually made from sturdy materials like plywood and are strategically placed in key areas of your home, especially in cripple walls. These walls offer extra support and stability, helping to minimize the risk of damage during an earthquake.
Bracing & Reinforcing
Next, we enhance the critical areas of your home in Eatonville by adding steel braces and straps. Our team installs these sturdy reinforcements in key structural elements like the roof, walls, and floors. This important step boosts your home’s overall stability, giving it a strong framework designed to withstand seismic forces.
Securing Applicances
Ensuring your appliances are securely anchored can help create a safer home for everyone in Eatonville. Securing items like water heaters and refrigerators is crucial. Our technicians can also install protective measures for gas meters to 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 ?
Western Washington 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.
