Foundation Repair Long Beach
Foundation problems can lead to significant damage to your home if they’re not taken care of. Signs like cracked floors, bowed walls, and sagging floors often indicate more serious structural issues. Residents of Long Beach, WA may also notice sticking doors, windows that won’t close correctly, or gaps appearing between walls and ceilings. These are all red flags that could mean your foundation is shifting, possibly due to soil movement, water damage, or the natural aging process.
At TerraFirma, we provide expert foundation repairs right here in Long Beach, WA, with specialized solutions designed to address the root cause of your foundation issues. Our process starts with a detailed inspection to evaluate the problem’s extent and source. From there, we recommend one or more of our trusted foundation repair systems:
Foundation piers
In Long Beach, WA, our push and helical piers are expertly designed to stabilize and elevate your foundation by directing its weight to deeper, more stable soil. Helical piers work best in areas with predictable soil conditions, while push piers are perfect for locations with uncertain stability. 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, providing you with confidence and peace of mind for your Long Beach home.
Basement Waterproofing Long Beach
Living in Long Beach, WA, you know that a wet basement can quickly turn into a big problem, leading to mold, mildew, structural damage, and poor air quality in your home. You might notice signs like musty smells, stained walls, pooling water, or efflorescence—a white, powdery residue that appears 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 Long Beach, ensuring your space stays dry, healthy, and functional—whatever the weather throws at it.
Crawl Space Repair Long Beach
Don’t underestimate your crawl space – it’s an essential part of your home’s structure and affects your air quality. In Long Beach, WA, 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 you and your family.
We understand the unique crawl space challenges in Long Beach, WA. That’s why TerraFirma offers tailored crawl space repair services to tackle moisture, mold, pests, and sagging floors with effective solutions like full encapsulation, drainage, and 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 Long Beach 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 Long Beach
Damaged, cracked, or uneven concrete isn’t just an eyesore—it can also pose a safety risk. These issues often arise from factors like inadequate soil compaction, freeze-thaw cycles, erosion, or tree root growth. Residents of Long Beach turn to us for quick and effective solutions to their concrete slabs, sidewalks, patios, and driveways.
TerraFirma provides quick, clean, and durable concrete leveling and repair solutions in Long Beach, WA, utilizing cutting-edge polyurethane foam injection and effective 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.

Earthquake Retrofitting Long Beach, WA
Long Beach, WA, is part of an active seismic zone in the Pacific Northwest. Homes built before the updated building codes of the 1990s can be particularly at risk. Even a small earthquake has the potential to shift a home off its foundation or cause serious structural damage.
TerraFirma’s earthquake retrofitting services help secure your Long Beach home to its foundation and strengthen its ability to withstand seismic events.
By retrofitting your home in Long Beach for earthquakes, you can lower your insurance premiums and deductibles, and even gain access to coverage options that weren’t available before the upgrade.
How We Retrofit
Assessment & Planning
The retrofitting process starts with a thorough assessment of your building’s current condition right here in Long Beach, WA. An expert, like a structural engineer or skilled technician, will inspect your home to spot any weaknesses and suggest the best solutions.
This assessment looks at the foundation, walls, roof, and overall structure of your building. From there, our engineer creates a detailed retrofitting plan tailored to what we discover.
Foundation Bolting
Stabilizing your home’s foundation is the next crucial step. Our technicians will install anchor bolts to securely connect your house to its foundation, helping to prevent any movement during an earthquake here in Long Beach.
Our process involves carefully drilling into the foundation and installing steel bolts. Once in place, our team tightens the bolts to reinforce your structure, boosting its stability and making it more resilient against seismic activity.
Adding Shear Walls
In Long Beach, WA, shear walls play a vital role in earthquake retrofitting by effectively distributing seismic forces, helping to keep your structure safe and sound during tremors.
Shear walls, made from plywood or other sturdy materials, are strategically installed in key areas of homes, especially in cripple walls. This added support enhances the walls’ stability, helping to minimize the risk of damage during an earthquake, an important consideration for residents in Long Beach, WA.
Bracing & Reinforcing
Next, we fortify essential areas of your Long Beach home with steel braces and straps. Our team installs these reinforcements on key structural components like the roof, walls, and floors. This crucial step enhances your home’s stability, ensuring it has a solid framework capable of withstanding seismic forces.
Securing Applicances
By securing your appliances, you can create a safer living environment for everyone in Long Beach, WA. It’s important to anchor items like water heaters and refrigerators, and our technicians can also install safety 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.

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.
