Foundation Repair Raymond
Foundation issues can lead to significant damage to your home if not taken care of. Signs like cracks in the floor, bowing walls, and sagging floors can indicate more serious structural concerns. Residents of Raymond, WA may observe doors that stick, windows that won’t close properly, or noticeable gaps between walls and ceilings. These issues could be indicators that your foundation is shifting due to soil movement, water damage, or normal wear and tear.
At TerraFirma, we provide specialized foundation repair services right here in Raymond. Our approach starts with a thorough inspection to identify the root cause of your foundation issues. From there, we recommend tailored solutions that fit your specific needs, backed by our effective foundation repair systems.
Foundation piers
Our push and helical piers are designed to stabilize and lift your foundation by transferring its weight to deeper, more stable soil. Helical piers work best in areas with known soil conditions, while push piers are ideal for locations with uncertain soil stability. Both options are minimally invasive and provide long-lasting solutions for your home in Raymond.
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 Raymond.
Basement Waterproofing Raymond
Living in Raymond, WA, you know the importance of keeping your home dry. A wet basement can cause serious issues like mold, mildew, structural damage, and poor air quality. Signs of water intrusion may include musty odors, stained walls, pooling water, or efflorescence—a white, powdery residue left behind when moisture evaporates. Even a small crack in your basement wall can become a gateway for unwanted moisture.
TerraFirma provides top-notch basement waterproofing solutions in Raymond to ensure your space stays dry, healthy, and functional, no matter the weather.
Crawl Space Repair Raymond
Crawl spaces in Raymond may be easy to forget, but they play a vital role in your home’s structure and air quality. If left unattended, these areas can become a breeding ground for mold, pests, and standing water. Neglecting your crawl space could lead to wood rot, unpleasant odors, and even health problems for you and your family.
We understand the crawl space conditions here in Raymond, WA, and TerraFirma’s repair services are tailored to tackle moisture, mold, pests, and sagging floors. Our solutions include 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 Raymond 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 Raymond
Damaged, cracked, or uneven concrete isn’t just an eyesore in Raymond—it can also pose a safety risk. Issues like poor soil compaction, freeze-thaw cycles, erosion, and tree root growth can lead to these problems. Local homeowners trust us to repair their concrete slabs, sidewalks, patios, and driveways swiftly and efficiently.
At TerraFirma, we provide quick, reliable, and durable concrete leveling and repair services in Raymond, WA, using innovative polyurethane foam injection and effective crack sealing.

- Cures in just 60 minutes.

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

Earthquake Retrofitting Raymond, WA
Living in Raymond, WA means being aware that much of the Pacific Northwest is in an active seismic zone. Homes built before the 1990s may be particularly at risk. Even a small earthquake can lead to significant issues, like shifting off foundations or serious structural damage.
TerraFirma’s earthquake retrofitting services help secure your Raymond home to its foundation and strengthen its ability to withstand seismic events.
Getting earthquake retrofitting done in Raymond not only helps protect your home, but it can also lower your insurance premiums and deductibles, and may even make you eligible for new coverage options that weren’t available before the upgrade.
How We Retrofit
Assessment & Planning
In Raymond, WA, our retrofitting process starts with a thorough evaluation of your building’s current condition. A qualified expert, like a structural engineer or a trained technician, will examine your home to pinpoint any weaknesses and suggest the best solutions.
This assessment involves inspecting the foundation, walls, roof, and overall structure. Following the evaluation, our engineer will create a detailed retrofitting plan tailored to the findings.
Foundation Bolting
Next, we’ll secure your foundation right here in Raymond. Our technicians will install anchor bolts to firmly connect your house to the foundation, helping to prevent any lateral movement during an earthquake.
Our process involves drilling into the foundation and installing steel bolts, which are then tightened to reinforce the structure. This improves stability and helps it withstand seismic forces, ensuring added safety for homes in Raymond.
Adding Shear Walls
Shear walls play a vital role in earthquake retrofitting in Raymond, WA, helping to distribute seismic forces and keep buildings standing strong during a quake.
Shear walls are typically made from plywood or other durable materials and are placed in strategic spots throughout homes, especially in areas known as cripple walls. They enhance support and stability, helping to lower the risk of damage during an earthquake right here in Raymond, WA.
Bracing & Reinforcing
Next, we enhance the stability of your home in Raymond by adding steel braces and straps to crucial areas. Our team installs these supports on important structural elements like the roof, walls, and floors. This vital step strengthens your home’s framework, making it more resilient against seismic forces.
Securing Applicances
Ensuring your appliances are secure helps create a safer home for everyone in Raymond. It’s important to anchor items like water heaters and refrigerators. Our technicians will 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 ?
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.
