Foundation Repair Kalama
Foundation problems can lead to significant damage to your home if not taken care of. In Kalama, WA, homeowners may notice signs like floor cracks, bowing walls, or sagging floors, indicating potential structural issues. If you find that your doors are sticking, your windows won’t close properly, or you see gaps between the walls and ceilings, these could all point to foundation shifts caused by soil movement, water damage, or simply the passage of time.
At TerraFirma, we specialize in foundation repairs right here in Kalama. Our expert team provides tailored solutions designed to address the specific issues affecting your foundation. We start with a thorough inspection to understand the extent and source of the problem, and then we recommend one or more of our reliable foundation repair systems.
Foundation piers
In Kalama, WA, our push and helical piers are expertly designed to stabilize and lift your foundation by shifting its weight to deeper, more stable soil. Helical piers work best in areas with known soil conditions, while push piers are great for places where soil stability is uncertain. 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 right here in your Kalama home.
Basement Waterproofing Kalama
Living in Kalama, WA, you know that a wet basement can cause serious issues like mold, mildew, structural damage, and poor air quality in your home. Signs of water intrusion might include musty odors, stained walls, puddles, or efflorescence, which is that powdery white residue that appears when water evaporates. Even a tiny crack in your basement wall can turn into a major gateway for moisture.
TerraFirma provides top-notch basement waterproofing solutions in Kalama, ensuring your space stays dry, healthy, and functional—regardless of the weather.
Crawl Space Repair Kalama
Crawl spaces in Kalama often get overlooked, yet they’re vital for 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 health concerns for your family.
We understand the unique crawl space conditions in Kalama, WA, and TerraFirma’s repair services are tailored to tackle moisture, mold, pests, and sagging floors. Our solutions include full encapsulation, effective drainage, and sturdy structural support to keep your home safe and healthy.
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 Kalama 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 Kalama
Damaged, cracked, or uneven concrete is more than just an eyesore—it poses safety risks too. These issues can arise from factors like poor soil compaction, freeze-thaw cycles, erosion, or tree root growth. That’s why homeowners in Kalama trust us to repair their concrete slabs, sidewalks, patios, and driveways swiftly and efficiently.

Earthquake Retrofitting Kalama, WA
Kalama, WA, is situated in an area known for its seismic activity, making it important for homeowners to be aware of potential risks. Homes built before the updated building codes of the 1990s face a higher vulnerability. Even a small earthquake can lead to significant issues, such as a home shifting off its foundation or suffering serious structural damage.
TerraFirma’s earthquake retrofitting services help secure your Kalama home to its foundation and strengthen its ability to withstand seismic events.
Retrofitting your home for earthquakes in Kalama can help lower your insurance premiums and deductibles, and may even make you eligible for coverage that wasn’t available before the upgrade.
How We Retrofit
Assessment & Planning
In Kalama, WA, our retrofitting journey starts with a comprehensive assessment of your building’s current state. A qualified expert, like a structural engineer or a trained technician, will inspect your home to pinpoint any weaknesses and suggest the best solutions.
This evaluation involves taking a close look at the foundation, walls, roof, and overall structure of your property. Afterwards, our engineer will create a detailed retrofitting plan tailored to the findings.
Foundation Bolting
Securing the foundation is a crucial next step. Our technicians install anchor bolts to firmly attach your home to its foundation, ensuring it stays stable and protected during an earthquake.
In this process, we drill into the foundation and insert steel bolts, which our team tightens to reinforce the structure. This not only improves stability but also boosts its resistance to seismic activity, ensuring a safer environment for Kalama residents.
Adding Shear Walls
Shear walls play a vital role in earthquake retrofitting in Kalama, WA, by evenly distributing seismic forces to help protect your home from collapse.
In Kalama, WA, shear walls are often made from plywood or other durable materials, strategically placed throughout homes, especially in cripple walls. These walls add vital support and stability, helping to minimize the risk of damage during an earthquake.
Bracing & Reinforcing
In Kalama, the next step involves strengthening key parts of your home with steel braces and straps. Our team expertly installs these reinforcements onto essential structural elements like the roof, walls, and floors. This crucial process boosts your home’s overall stability, creating a resilient framework that can better handle seismic activity.
Securing Applicances
Securing your appliances can help create a safer home for you and your family in Kalama. It’s important to anchor essential items like water heaters and refrigerators. Our technicians also provide protection for gas meters to minimize 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.
