Foundation Repair Manzanita

Foundation problems can lead to significant damage to your home if not taken care of. If you’re in Manzanita, OR, keep an eye out for signs like cracks in your floors, bowing walls, and sagging floors, as these often indicate deeper issues. You might also notice doors that stick, windows that aren’t closing properly, or gaps appearing between your walls and ceilings. These could all be indicators that your foundation is shifting due to soil movement, water damage, or simply the passage of time.

At TerraFirma, we specialize in foundation repair right here in Manzanita, offering expert solutions designed to address the unique issues affecting your foundation. Our process begins with a thorough inspection to determine the extent and cause of the problem. From there, we’ll recommend one or more of our trusted foundation repair systems to get your home back on solid ground.

Foundation piers

At our Manzanita location, our push and helical piers are designed to stabilize and lift your foundation by anchoring it to deeper, more stable soil. Helical piers work great in areas with known soil conditions, while push piers are ideal for locations with uncertain soil 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, ensuring you feel confident and at ease in your Manzanita home.

Basement Waterproofing Manzanita

Dealing with a damp basement in Manzanita? It can lead to mold, mildew, structural issues, and poor air quality in your home. You might notice musty odors, stained walls, pooling water, or efflorescence—a white powdery residue left when water evaporates. Remember, even a small crack in your basement wall can turn into a significant entry point for moisture.

TerraFirma provides top-notch basement waterproofing solutions in Manzanita, ensuring your space stays dry, healthy, and functional—whatever the weather brings.

Interior Drainage Solutions

In Manzanita, OR, we create custom drainage systems that effectively redirect water away from your basement and into sump pumps, safeguarding your foundation.

Basement Drainage System: Our most popular system, it’s installed below the floor slab and above the footing to prevent clogging.
Perimeter Drainage System: Ideal for monolithic foundations where jackhammering is not feasible.
Thin-floor Drainage System: A thin-floor drain system used in basements with thin concrete slabs.
Grated Trench Drain: Block ground air from entering while allowing water to drain.

Sump Pump Systems

We offer several sump pump options tailored to your water exposure:

Multi-pump Sump System: Three-pump system for maximum protection, including battery backup for power outages.
Battery Backup Sump Pump: High-capacity battery backup pump that activates when the main pump fails or power goes out.
Basement Sump Pump System: A single-pump system for homes with minor water issues.

Vapor Barriers & Dehumidifiers

Vapor Barrier Elite: A heavy-duty wall liner that stops moisture and mold while directing water into drainage systems.
Basement Dehumidifier Sedona & XP: Energy-efficient dehumidifiers that remove up to 109 pints of moisture daily, improving air quality and comfort.

Window Wells & Drains

Our Basement Window Well Enclosure and Window Well Drainage System keep your basement bright, dry, and free from debris, while meeting egress codes for safety.

Waterproofing in Manzanita, OR not only safeguards your investment but also turns your basement into a safe and functional extension of your home.

Crawl Space Repair Manzanita

Crawl spaces in Manzanita homes are often forgotten, yet they play a vital role in your house’s structure and indoor air quality. If not properly cared for, these spaces can become a breeding ground for mold, pests, and standing water. Neglecting your crawl space can result in wood rot, unpleasant odors, and even respiratory problems for you and your family.

We understand the unique crawl space conditions in Manzanita, OR, and TerraFirma’s crawl space repair services are tailored to tackle moisture, mold, pests, and sagging floors with comprehensive encapsulation, drainage solutions, and structural support.

Encapsulation & Drainage

We begin by sealing the crawl space with our Vapor Barrier, 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.
Crawl Space 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 Manzanita 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 Basement 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 Manzanita, OR

Manzanita, OR, lies within a region that’s known for its seismic activity. Homes built before the updated building codes of the 1990s may be at greater risk. Even a small earthquake could cause a home to shift off its foundation or sustain significant structural damage.

TerraFirma’s earthquake retrofitting services help secure your Manzanita home to its foundation and strengthen its ability to withstand seismic events.

Upgrading your home with earthquake retrofitting in Manzanita can not only enhance safety, but it may also help lower your insurance premiums and deductibles, plus open up access to coverage options that weren’t available before.

How We Retrofit

Assessment & Planning

In Manzanita, the retrofitting process starts with a thorough assessment of your home’s current condition. A qualified expert, like a structural engineer or trained technician, will evaluate your property to pinpoint any weaknesses and suggest the best solutions.

Our evaluation looks at the foundation, walls, roof, and overall structure. After that, our engineer creates a detailed retrofitting plan tailored to the findings.

Foundation Bolting

Securing the foundation is the next step in our process. Our technicians install anchor bolts to connect your home to its foundation, ensuring it stays steady and strong during an earthquake here in Manzanita.

In Manzanita, we strengthen your home’s foundation by drilling holes and using sturdy steel bolts. Our team expertly tightens these bolts to enhance the structure’s stability, ensuring it stands strong against seismic activity.

Adding Shear Walls

In Manzanita, OR, shear walls play a vital role in earthquake retrofitting by helping to distribute seismic forces and keep buildings standing strong.

Shear walls are usually made from sturdy materials like plywood and are placed in key areas of your home, especially in cripple walls. These walls add essential support and stability, helping to mitigate the risk of damage during an earthquake here in Manzanita.

Bracing & Reinforcing

Next, we strengthen key areas of your Manzanita home using sturdy steel braces and straps. Our team carefully installs these reinforcements on essential structural elements like the roof, walls, and floors. This process boosts your home’s stability, ensuring it has a solid framework that can withstand seismic forces.

Securing Applicances

Ensuring your appliances are properly secured creates a safer home for everyone in Manzanita. It’s vital to anchor items like water heaters and refrigerators, and our technicians will 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.

Manzanita
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 Vapor Barrier 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 Grated Trench 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 Basement Drainage System and Perimeter Drainage System 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.

Barry L.

We had a mud/water disaster. Called TerraFirma and they got here the next morning. Mark Johansen figured out the problems, cleaned out the blockages and flushed the whole system, and now everything is flowing right. Great service; great problem-solving skills.

Kevin W.

Everyone with TerraFirma were great to work with. They were professional and did not treat me like I was stupid when I had questions. The installation crew were great and left my house leaving no mess behind. Best yet is that my basement is no longer flooding. I recommend TerraFirna highly

Julie B.

Terrafirma just completed the EverBrace wall system on our basement and we couldn't be happier. The house has stopped shaking when the tenant upstairs does laundry. Rocky, our project foreman was outstanding to work with. His communication was fantastic. The project site was well managed. He was always realistic about the daily impacts we might feel while the project was underway (it can get quite noisy) and he was able to flex the project noise level so it wouldn't impact our upstairs tenant. Sammy, their project coordinator, stayed in communication with me from the moment our contract was signed through the project completion. The only suggestion we have if you're considering the Everbrace wall system, is that you may need to manage some additional work to prepare for the system. Plumbing electrical and HVAC systems will most likely need to be moved. Factor this in both financially and timewise.

Harry T.

Marcus performed the 5th annual checkup on our TerraFirma (TF) foundation system. Like all TF technicians we've dealt with, Marcus was very professional with a solid understanding of our system. He checked both pumps and the dehumidifier. He also assessed the general condition of our crawl space. When he finished the inspection, he reported his findings (favorable!) and showed us pictures where he cleaned up around the pumps. This is a great company. I recommend TerraFirma wholeheartedly.

Patrick H.

Very happy with job the company did. Price was fair, and project was done on time

Cheryl S.

I had TerraFirma foundations repair my crawl space issues, the 3 men that came out to do the job were very professional and cautious. Jorge, Juan B, and Manual J, did an exceptional job and Jorge explained everything that they were doing and showed me lots of pictures during the process. After the job was finished they made sure everything was cleaned and put back together. Than I received a call from the project manager Jonah, to make sure everything went well and he made sure I was happy with the job. I recommend TerraFirma to everyone!!!!!

Kimberly P.

I waterproofed and put a sump pump in my 1890s basement. There was a trench around the basement floor originally. the stairs leading outside to the basement leaked water into the trench as well as some moisture from the wall. The crew was amazing! They were prompt, very communicative as to what they would be doing to make the basement dry. They worked hard and got the project done on time. I would highly recommend them. I do believe there may be other more economical ways to waterproof, however this was done right!

Alex J.

The best. Hands down. TerraFirma came out and inspected our leak in the basement and I couldn't be more impressed with the service. We are new homeowners and didn't know anything about how their system actually worked. Travis and his partner (sorry I didn't get your name!) took the time to explain how our system works and answered all of the questions we asked. 10/10 would recommend TerraFirma to anyone. *The leak was unrelated to the system TerraFirma put in, but they stuck around to answer questions anyways*

Marty

Very easy to work with from the time I contacted them for a quote, to having someone come and look at the job, to scheduling the work. Professional, courteous, and good follow-up throughout the process. Job was completed to my satisfaction.

john D.

Always professional with great outcomes. I high recommended Terra Firma.

Matt W.

Even before the crew was onsite, I very much appreciated Geovany's site visits and communication (along with that of our Project Managers!). The install crew that completed our foundation repairs were just excellent as was the final product. We were very pleased and satisfied with Bryan and his crew members (Oscar, Oscar, and Cam). On the final day Bryan teamed with Nate and his crew of two (Oscar and a person's name I didn't get). All crew members were respectful, tidy, and were able to accommodate our requests as we sought to coordinate extra loud construction periods for our noise sensitive young child. Bryan, as crew lead, communicated well, sought to always provide a clear explanation of the work, received any and all questions and feedback, sought to install a professional product, and thoughtfully shared what the next day would look like. The finished product was completed, in my opinion, with integrity both to the contract signed and also to professional construction methods. We have been genuinely satisfied with this particular phase of the work (foundation repair) and I would very much recommend TFFS, and specifically the crew we had onsite, to others facing similar crawlspace/foundation nightmares. Update following waterproofing crew: Now that the final waterproofing phase is complete we are very satisfied with the completed work, as well as the professional manner, of the waterproofing crew. Our crawlspace is completely transformed and probably hasn't ever looked this good in the 43 years since this house was first constructed. We sleep better at night now knowing our foundation is structurally sound and encapsulated. The final week of work by the waterproofing crew saw a thorough and detailed approach as they installed the perimeter drainage, applied the 120-mil vapor barrier along with its heavy duty underlayment, and the foam board - among all the other details they accomplished. The crew went above and beyond, doing even a bit more than I ever expected. Most importantly, for our family, foreman Tim C., with team members Chris R., Tarin S., and Jairo T., were very thoughtful and respectful as we had a child sensitive to loud noise - the crew kept us informed and really worked well to accommodate our needs. Our crew, led by Tim C., not only earned a shout out but please recognize those guys. Perhaps this has been the most surprising part of our journey with TerraFirma - how excellent it has been to work with the onsite foremans and their crews.

Michael C.

TerraFIrma has been a great company to work with. Always on top of communications. The team showed up at my home and got busy! The lead-man was on top of the situation, and kept me informed on the progress of the project. Unfortunately I have additional work that needs to be done, as this is an old home. TerraFirma will be the company I use on the next phase.
