Job Stories From Marietta, OH
Stabilizing and Waterproofing a Home in Marietta, OH

After living in their house for 20 years, homeowners in Marietta, OH, noticed some worsening problems in their basement. Several areas of the foundation walls were showing signs of failure in the form of various cracks, as well as inward tilting. Water also appeared to be leaking into the basement.

The owners wanted to fix these problems before serious damage resulted, so they began to research how to best address them. They found information about Ohio Basement Authority online and were motivated to contact us for further guidance. One of our inspectors visited to complete a thorough inspection of the home and its problematic basement. Our inspector then recommended some of our reliable basement waterproofing and foundation repair solutions.

One of our crews then installed Carbon Fiber supports and PowerBrace beams on the walls. Both of these solutions permanently stabilize the walls and prevent any further cracking or inward movement. But the walls can be potentially improved and straightened with the PowerBrace beams, and the Carbon Fiber supports hold the other walls in their current positions.

The basement also was waterproofed with the WaterGuard drainage system and UltraSump sump pump, as well as exterior IceGuard and Lawn Scape attachments. Any seeping water from the walls and floor is intercepted by the WaterGuard system and directed to drain into the UltraSump. This system, which features two pumps and an external backup battery, then pumps the water out of the basement. An IceGuard was attached to the exterior sump pump discharge line to prevent flooding from frozen or blocked lines, and a LawnScape was used to conceal the end of this buried discharge line in the yard.

The owners now have peace of mind knowing their home will be a safe, stable, healthy and dry living environment because of these trustworthy repairs.

Waterproofing a Leaking Basement in Marietta, OH

After living in her house for a few months, a homeowner in Marietta, OH, experienced something she was hoping to avoid. Water seeped inside the basement after heavy rains, resulting in puddles on the floor.

Concerned with the health and safety of her home, the owner wanted to nip this problem in the bud. She started to search for the best repair solution, and in doing so she came across Ohio Basement Authority’s website. She was then motivated to contact us to learn more about how we could help her. One of our inspectors visited to complete a thorough evaluation of the leaking basement. Our inspector then presented the owner with some of our reliable waterproofing solutions.

One of our crews then waterproofed the basement with the WaterGuard drainage system, an UltraSump sump pump and an exterior IceGuard attachment. Any seeping water will be intercepted by the sub-floor WaterGuard system and directed to the UltraSump. The UltraSump features two powerful pumps inside its liner, as well as an external backup battery to ensure the system will always operate to pump water out of the basement. An IceGuard also was attached to the exterior sump pump discharge line to prevent flooding from frozen or blocked lines.

The owner now has peace of mind knowing these trustworthy repairs are protecting her home.

Foundation Stabilization with Push Piers in Marietta, OH

After living in their house for six years, homeowners in Marietta, OH, started to notice potential structural problems with their house. These included cracks and gaps in a corner of the foundation. These issues indicate foundation failure and settlement.

The owners plan to live in the house for many years, so they wanted to be sure it would be structurally sound. After finding information online about Ohio Basement Authority, the owners were eager to contact us for assistance. They met with one of our inspectors who completed a thorough evaluation of the home. Our inspector then recommended one type of our many reliable foundation repair solutions.

One of our crews then installed several Push Piers underneath the settling foundation walls. These heavy-duty piers are driven down to more stable soil to stabilize and help lift the home back to level.

The homeowners can rest easier knowing their forever home is protected by these trustworthy repairs.

Updating an Exterior Drainage System in Marietta, OH

During the last couple years that they have lived in their house, homeowners in Marietta, OH, have noticed a problem outside their house getting worse. Water runoff from their neighbor’s house was causing the ground in their back yard to become saturated, and faulty drainage on one side of the house caused the ground to soften around the driveway. Water did not seem to be seeping inside the home, but that could eventually happen if the other problems persisted.

The homeowners began to research methods to update their exterior drainage, and they came across information for Ohio Basement Authority on resources like Home Advisor. They met with one of our inspectors who assessed the current drainage issues, and he then recommended having one of our crews install new exterior drainage lines.

New reliable downspout conductor lines and French drain lines were then installed on the property. Thick pipe was used for these systems that were connected to the gutter downspouts and buried underground. The French drain section comprised of perforated pipe seated in non-compactable gravel. This allows water to slowly leach in and drain to the appropriate area away from the home. The downspout lines also were directed to drain water at the edge of the property.

The homeowners are happy to now have an up dated exterior drainage system.

Stabilizing a Sagging Floor with SmartJacks in Marietta, OH

After living in their house for several years, homeowners in Marietta, OH, recently started to notice a structural issue getting worse. A main load bearing beam in the attached garage was starting to sag. This also caused some unlevel floors above the garage. These issues could eventually worsen and compromise the structural integrity of the home and garage.

The homeowners wanted to find the best way to address these problems, so they turned to the Internet for research. They came across Ohio Basement Authority’s website, and they were eager to contact us to learn more about how we could help them. After meeting with one of our inspectors, one of our crews then installed the perfect solution.

Two SmartJacks were installed in the garage to stabilize the main load beam and above floors. SmatJacks may look similar to common jack posts, these heavy-duty supports are made of galvanized steel. This enhances their durability and also makes them resistant to rust, corrosion and rot. The SmartJacks permanently reinforce the above floors and can help raise them back to level. SmartJacks also are designed to prevent any further settling, but they can easily be adjusted if any settling occurs.

The homeowners were pleased to have this reliable foundation repair project completed so their home will be safer and stable for many years to come.

Correcting a Cracking, Leaking Basement in Marietta, OH

After living in his house for 14 years, a homeowner in Marietta, OH, began to notice water leaking through cracks in the foundation walls. These telltale signs of foundation wall failure are common, yet hazardous.

The home was built almost 40 years ago, and during that time the foundation walls have been subject to hydrostatic pressure. As the soil directly outside the foundation walls becomes saturated, it expands and exerts a lot of pressure on the walls. This continuous force, also known as hydrostatic pressure, takes its toll on the walls and begins to push them inward. Evidence of this can be seen in horizontal and stair-step cracking patterns.

The homeowner wanted to make sure the basement would always be dry and structurally sound, so he contacted Ohio Basement Authority after seeing one of our TV ads. One of our experienced inspectors completed a thorough evaluation of the home and presented the owner with a variety of permanent solutions.

The owner was eager for us to install several heavy-duty structural steel I-Beams along the walls to permanently stabilize them. We also installed four SmartJacks in the crawl space to stabilize sections of sagging floors.

We waterproofed the basement by installing the WaterGuard drainage system in the sub-floor to intercept any seeping water. This interior drainage system was connected to an exterior gravity fed drainage system. LawnScape outlets also were placed over the ends of these exterior drainage pipes that were directed to the backyard.

The homeowner now has peace of mind knowing these reliable foundation and waterproofing solutions have helped him create a safer and healthier living environment.

Stabilizing Cracked Foundation Walls in Marietta, OH

It’s difficult to sell a home when water is coming through its cracked and bowing foundation walls. This is something a homeowner in Marietta, OH learned the hard way.

When potential home buyers saw the walls, they expressed their concerns to the homeowner, so he called Ohio Basement Authority to repair the failing foundation.

We applied carbon fiber straps along the three less-effected walls to strengthen them and prevent future failure. Carbon fiber is a very strong material that is nearly impossible to bend or stretch.

Then, the crew installed two versions of the Geo-Lock Anchor System along the most problematic wall. The first was one Geo-Lock Channel Anchor. This is a steel column attached to the foundation floor and the wall to correct cracks and bowing that occur toward the bottom of the wall.

Second, we installed four Geo-Lock Foundation Wall Anchors along the rest of the wall. These are steel anchors which are embedded into hard-packed, untouched soil outside of the foundation wall. These anchors are attached to the wall with galvanized steel rods which are tightened to pull the foundation back into place.

These reliable repairs have eased the homeowner’s and potential home buyers’ concerns and worries. 

Crawl Space Encapsulation in Marietta, OH

After living in their house for three years, homeowners in Marietta, OH, were growing frustrated with the condition and appearance of the partial crawl space adjacent to their basement. It was full of debris and seemed to be an unhealthy area of the home.

They were unsure how to address these issues, but they were eager to contact Ohio Basement Authority after learning more about our company and our services through our website. We then transformed the nasty area under their home into a more functional space.

After removing the debris, we encapsulated the crawl space in CleanSpace liner. This thick liner completely isolates the home environment from the earth. It also acts as a moisture and vapor barrier, and it helps insulate the crawl space. The thick material is durable and tough enough to crawl on, making the crawl space an ideal storage area.

The homeowners are happy to have a healthier crawl space and home they will be able to enjoy for many years to come.

Permanent Basement Waterproofing and Foundation Repair in Marietta, OH

After living in her house for more than 20 years, a homeowner in Marietta, OH, began to notice cracks in a foundation wall and water seeping into the basement. She was concerned these issues could affect the health and stability of her home, so she began to research repair options and companies.

She contacted Ohio Basement Authority, and we installed some of our many reliable waterproofing products and foundation repair products.

These included the WaterGuard interior drainage system and UltraSump Battery Backup System. If any water seeps into the basement, it will be intercepted by the WaterGuard System. The water is then directed to the reliable UltraSump system that will safely and effectively pump the water out of the basement and away from the home’s foundation. The UltraSump’s external backup battery ensures the system will always work even in the event of a power outage. An IceGuard also was attached to the exterior sump pump discharge line.

Several Carbon Fiber supports were installed on the problematic foundation wall to permanently stabilize it and prevent further cracking or inward bowing.

The homeowner was pleased these reliable solutions were installed so her home will be a healthy, safe and stable living environment for many years to come.

Work Requests From Marietta, OH
Vicinity of Wynncrest Drive in Marietta
Our front basement wall has a stairstep crack from top to bottom, near the corner of the wall, and part of the wall has been pushed in about 3/4 of an inch. The wall was previously repaired over 11 years ago, before we bought the house, and they had installed concrete braces. One of the braces has now been pushed in with the other part of the wall. Our house sits slightly downhill from the road, so we get all of the runoff.

I've been told that my crawl space isn't bad... as far as nasty crawl spaces go. However, I do not go down there! I would like for someone to evaluate and provide estimate on what it may need to make the environment healthier, dry, and rodent free. My home is not too old but I do not want to chance something down there making my home devalue or be unsafe or unhealthy. Possible Encapsulation might be the thing.
