Foundation Repair Auburn
Foundation problems can lead to significant damage to your home if not taken care of promptly. In Auburn, WA, you might spot warning signs like cracks in the floor, bowing walls, or sagging floors, which could indicate more serious structural issues. Homeowners may also experience doors that stick, windows that refuse to close properly, or gaps between the walls and ceilings. These symptoms often point to foundation shifts caused by soil movement, water damage, or the natural wear and tear that comes with age.
At TerraFirma, we specialize in foundation repairs in Auburn, WA, offering expert solutions designed specifically for the unique challenges you face. Our process starts with a thorough inspection to identify the source and extent of your foundation issues. From there, we’ll recommend one or more of our reliable foundation repair systems tailored to your needs.
Foundation piers
Our push and helical piers are designed to stabilize and lift your foundation by transferring its weight to deeper, more stable soil layers. Helical piers work best for areas with known soil conditions, while push piers are ideal for locations where soil stability is uncertain. Both systems are minimally invasive and provide lasting solutions for your foundation needs in Auburn.
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, offering you confidence and peace of mind for your home in Auburn.
Basement Waterproofing Auburn
Experiencing a wet basement in Auburn, WA? It can lead to issues like mold, mildew, structural damage, and poor air quality in your home. Look out for signs of water intrusion such as musty odors, stained walls, pooling water, or white, powdery efflorescence left behind as water evaporates. Even a tiny crack in your basement wall can quickly turn into a significant source of moisture.
TerraFirma provides top-notch basement waterproofing solutions in Auburn to keep your space dry, healthy, and functional, rain or shine.
Crawl Space Repair Auburn
Crawl spaces in Auburn, WA, are often forgotten, but they play a vital role in 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.
We understand the unique crawl space challenges in Auburn, WA. That’s why TerraFirma offers tailored crawl space repair services to tackle moisture, mold, pests, and sagging floors with complete encapsulation, effective drainage solutions, 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 Auburn 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.

Earthquake Retrofitting Auburn, WA
Auburn, WA, is located in a region of the Pacific Northwest that sits within an active seismic zone. Homes built prior to the updated building codes implemented in the 1990s may be particularly at risk. Even a minor earthquake could lead to your home shifting off its foundation or suffering significant structural damage.
TerraFirma’s earthquake retrofitting services help secure your Auburn home to its foundation and strengthen its ability to withstand seismic events.
Retrofitting your home for earthquakes in Auburn not only strengthens your property, but it can also lower your insurance premiums and deductibles, plus help you qualify for coverage that may not have been available before the upgrade.
How We Retrofit
Assessment & Planning
The retrofitting process in Auburn, WA 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 vulnerabilities and suggest the best solutions.
This assessment involves inspecting the foundation, walls, roof, and overall structure. Afterward, the engineer creates a detailed retrofitting plan tailored to the findings.
Foundation Bolting
Ensuring a sturdy foundation is the next key step here in Auburn. Our technicians install anchor bolts to securely attach your home to its foundation, keeping it stable and preventing any lateral movement during an earthquake.
In this process, we drill into the foundation and insert sturdy steel bolts. Our team tightens these bolts to strengthen the structure, improving its stability and ability to withstand seismic forces right here in Auburn, WA.
Adding Shear Walls
Shear walls play an essential role in earthquake retrofitting for buildings in Auburn, WA, helping to distribute seismic forces and keep structures safe from collapsing.
Shear walls are usually made of plywood or other sturdy materials, and they’re installed 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 in Auburn.
Bracing & Reinforcing
Next, we enhance the critical areas of your Auburn home by installing sturdy steel braces and straps. Our team carefully secures these to essential structural components like the roof, walls, and floors. This crucial step boosts your home’s overall stability, ensuring it has a resilient framework capable of withstanding seismic forces.
Securing Applicances
Securing your appliances is key to creating a safer living environment in Auburn, WA. Making sure items like water heaters and refrigerators are anchored is essential. Our technicians 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.

Auburn
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.
