Concrete Repair With PolyRenewal®!

If you have a concrete sinking problem, we also offer concrete leveling so you can enjoy your driveway, sidewalk or patio again without worry. In the past, contractors relied upon mud jacking (also known as slab jacking, concrete lifting, concrete raising, grout pumping and slab leveling) to level concrete that had settled over time. This entailed pumping concrete slurry under the settled slab to raise it and hoping that the settlement wouldn't continue. At Ohio Basement Authority we use PolyRenewal® because it is a fast & efficient method to raise sinking concrete. This simple foam injection can stabilize your concrete slab for years to come!

Foundation Repair in Thornville, OH
After living in their house for five years, homeowners in Thornville, OH, began to notice some cracking in the exterior walls, as well as inside their basement. These issues are telltale signs of foundation failure and even foundation settlement. Concerned for the safety and structural integrity of their house, the owners began to research repair options. They were eager to contact Ohio Basement Authority after learning more about our company online. After meeting with one of our expert inspectors, the homeowners were eager for our experienced crews to stabilize a cracking interior foundation wall and exterior porch. First, two Helical Piers were installed underneath the porch built on a low-profile block foundation wall. These durable galvanized steel piers were driven down to competent soil and attached to heavy-duty foundation brackets on the home’s footing. These piers permanently stabilize the foundation, help prevent further settlement, and offer the best opportunity to lift the settling section back to level. Another reliable foundation repair solution also was used in the basement. Several Carbon Fiber supports were placed on a cracking foundation wall to permanently stabilize it and prevent any future cracking or inward bowing. The homeowners are pleased to now have a safer living environment they will be able to enjoy for many years to come.
Foundation Repair with Carbon Fiber Supports in Thornville, OH
During the three years they have lived in their house, homeowners in Thornville, OH, have noticed structural issues getting worse. One of the foundation walls was cracking and beginning to tilt inward. These are common signs of foundation wall failure, but the homeowners wanted to make sure it would not worsen and result in serious damage. They started to research how to best address these problems, and they were eager to contact Ohio Basement Authority after learning more about our company online. After meeting with one of our inspectors, the owners were equally eager for one of our crews to install one type of our many reliable foundation repair solutions. We placed several Carbon Fiber supports on the problematic foundation wall. These sturdy supports adhere to the wall to permanently reinforce it where they are installed. They also protect the wall from any further cracking or bowing. The homeowners are happy to now have a stable living environment because of this reliable solution.
Permanently Waterproofing a Leaking Basement in Thornville, OH
After living in her house for almost 20 years, a homeowner in Thornville, OH, recently began to notice she had a leaking basement. Water seemed to seep inside through any nook or cranny, leaving puddles and visible damage behind. The owner wanted to address this issue once and for all, so she began to research potential repair options and companies. She was eager to contact Ohio Basement Authority after learning more about our company through online resources like Home Advisor. After meeting with one of our experienced inspectors, the owner was equally excited for one of our expert crews to install some of our reliable basement waterproofing solutions. These included the BasementGutter interior drainage system and SafeDri Super sump pump. If any water seeps into the basement, the sub-floor BasementGutter system will intercept it and direct it to the SafeDri Super sump pump. This powerful sump pump will then pump the water safely out of the basement and away from the home’s foundation. A FreezeGuard was attached to the exterior sump pump discharge line, and this line was tied into new downspout conductor lines that also were installed on the property. The owner now has peace of mind knowing these trustworthy solutions have helped her create a safer and healthier home.
Permanently Waterproofing and Older Home in Thornville, OH
After living in their 150-year-old house for a few months, homeowners in Thornville, OH, were discovering areas of the home that needed attention. One of these was potential water in the basement. While there was no standing water, the owners could tell the floors were moist. The sump pump also seemed to run constantly. The owners wanted to make sure the basement would always be dry, so they began to research possible repair options and companies. They were eager to contact Ohio Basement Authority after learning more about our company and our services through online resources like Home Advisor. After meeting with one of our highly trained inspectors, the owners were equally excited for one of our expert repair crews to transform their basement into a dry and healthy area. We did this by installing the BasementGutter drainage system in the basement’s sub-floor. If any water seeps inside through the walls or area where the walls and floor meet, it will be intercepted by the BasementGutter System. From there, the water will be directed to the SafeDri Battery Backup System. The back-up battery also enables the system to continue to operate even in the event of a power outage. Additional installations included the grated drainage system in front of the walk-out access, exterior FreezeGuard attached to the sump pump discharge line, and YardWell outlet attached to the end of the exterior drainage line. The walls also were covered with CrawlSeal liner. The homeowners now have peace of mind knowing they will have a healthier living environment that they will be able to enjoy for many years to come.
Sealing a Nasty Crawl Space in Thornville, OH
After living in her house for several years, a homeowner in Thornville, OH, began to investigate the process of selling her home. Before putting the house on the market, the owner knew the home needed various repairs. This included addressing the nasty crawl space. This area underneath the home was filled with debris, failing insulation and plastic floor liner, and the environment was very humid and moist. These issues concerned the homeowner, and they wanted to address these problems so the next owners would not have to worry about them. After learning more about Ohio Basement Authority from our website, the owner was eager to contact us for a permanent solution. She also was excited for one of our expert crews to transform the crawl space. We did this by first removing the nuisances from the crawl space, then encapsulating the area in CrawlSeal liner. Similar to swimming pool liner, CrawlSeal is thick and durable, and it completely isolates the crawl space from the earth. CrawlSeal acts as a moisture and vapor barrier, and it helps insulate the crawl space. Additional installations included spray foam insulation that was applied to the band joists, and the dehumidifier that helps control the humidity, clean and filter the air, and reduce odors. The owner now has peace of mind knowing these trustworthy solutions have helped her create a safer and healthier living environment for the next owners.
IntelliJacks Stabilize and Raise Sagging Floors in Thornville, OH
They have lived in their house for several years, but it wasn’t until recently that homeowners in Thornville, OH, began to notice sections of their floors were sloping and sagging. These can be signs of foundation settlement or a failing support system. The homeowners wanted to address these potential issues before they worsened, so they began to research repair options and companies. They contacted Ohio Basement Authority after learning more about our company online, and one of our inspectors completed a thorough evaluation of the home. After he presented the owners with various repair options, they were eager for one of our expert crews to permanently stabilize their home. We did this by installing several IntelliJacks in the crawl space underneath the house. The support beams were beginning to fail, resulting in sagging floors. But the heavy-duty, galvanized steel IntelliJacks permanently stabilize the floor and floor joists. They also prevent further sagging and offer the best opportunity to lift the floors back to level. The IntelliJacks will not rust or corrode. They also are designed to stop settling, but can easily be adjusted if any settlement occurs. The homeowners now have peace of mind knowing the home will be a safer and structurally sound living environment for many years to come because of this reliable repair solution.
Stabilizing Sagging Floors in Thornville, OH
Their house has been handed down within their family for many years, so maintaining a healthy, safe and stable living environment is very important to homeowners in Thornville, OH. They recently noticed areas of the floor were sagging. This can be a sign of foundation settlement and failure of the home’s structural support system. After learning more about Ohio Basement Authority and our repair options through our website, the owners were eager to contact us for a permanent solution. Along with additional supports in the crawl space, we installed several IntelliJacks. These heavy-duty, galvanized steel supports permanently stabilize the floor joists and help raise the floor back to level. They also will not rust or corrode. They are designed to stop settling, but can easily be adjusted if any settlement occurs. We also addressed the issue of secure access to the crawl space. We did this by installing the access well and crawl space door that is more durable, attractive, and secure than conventional access points. The homeowners now have peace of mind knowing the home will be safe and structurally sound for many years to come.
BasementGutter and SafeDri Will Keep a Leaking Basement Dry in Thornville, OH
Homeowners in Thornville, OH, have lived in their house for almost 10 years. Ever since they expanded their home by having a basement constructed, they have been dealing with a leaking basement. Water seemed to seep inside during heavy rains, resulting in puddles, visible damage and even flooding. This greatly concerned the homeowners, who were promised a dry basement by their contractor. Hoping to find a permanent solution, the owners were eager to contact Ohio Basement Authority after seeing one of our TV ads. They met with one of our experienced inspectors who completed a thorough evaluation of the basement, and they were equally excited for one of our expert crews to install some of our many reliable foundation repair products. We placed the BasementGutter interior drainage system in the basement’s sub-floor to catch any water that might seep into the basement through the walls or floor. This water is then directed to the SafeDri Triple sump pump system that replaced the older, failing sump pump. The SafeDri is equipped with three powerful pumps inside its liner, as well as an external backup battery. This reliable system will always work to pump any seeping water out of the basement. We also installed the powerful, yet energy-efficient dehumidifier in the basement. This system cleans and filters the air, and helps control humidity and reduce odors. Unlike conventional dehumidifiers, this self-drains so no buckets have to be emptied. The homeowners now have peace of mind knowing these trustworthy installations will always keep their basement dry.
Waterproofing and Stabilizing a Home in Thornville, OH
After living in their house for almost 30 years, homeowners in Thornville, OH, were motivated to address their leaking basement once and for all. Water seemed to seep into the basement through the walls during heavy rains, leaving puddles and visible damage behind.

The walls were cracking, sections of the floor were sagging, and the front stoop had settling concrete. They wanted to address all of these issues, and they were excited for our crews to help transform their home. We installed several basement waterproofing products that will always keep their home dry. These included the sub-floor BasementGutter interior drainage system, a powerful SafeDri sump pump, and a dehumidifier. The cracking walls were reinforced with several Carbon Fiber supports, and the sagging floors were stabilized and raised back to level with several IntelliJacks. The exterior sinking concrete was lifted and leveled with the PolyRenewal System. The homeowners now have peace of mind knowing these reliable repairs have helped them create a safer and healthier living environment.
Radon Mitigation in Thornville, OH
Before moving into his house, a new homeowner in Thornville, OH, wanted to ensure the health and safety of the home. He wanted to address any radon in the home. Radon is a naturally occurring radioactive as produced by the decay of uranium in rocks and soil. This gas is colorless, odorless and tasteless, but also very hazardous. Radon is a leading cause of lung cancer, and it has been linked to more than 20,000 annual deaths. After testing the house, the results indicated its radon level was 4 picocuries per liter (pCi/L). This is the Environmental Protection Agency’s radon action level, and the owner wanted to try to low the home’s level as much as possible. The owner’s realtor recommended contacting Ohio Basement Authority, and he was eager to learn more about how we could help him. He met with one of our inspectors who reviewed the radon test results with him as well as our company’s mitigation procedures. One of our crews then installed a radon mitigation system to draw radon from the house and help lower the radon level as much as possible. The new owner is pleased to have a healthier living environment because of this trustworthy solution.

I just wanted to thank you for all your help and patience with my encapsulation project.

I am very happy with the work that was done, and the crew that did the work. They were all very professional, considerate, and kept me informed about everything they were doing.

I have noticed a big difference in the humidity in the house. I have had no condensation on my windows at all, even with the cold temps we have had this winter. What a difference! I do believe that it is helping to keep the house warmer, and will help in the summer to keep the house cooler and humidity down.

I just wanted to let you know that I was very happy with all you did, and all the help you and the guys who worked on my project did. My experience with your company has been great, and I would recommend your company to anyone who is having crawl space issues.

I wish you the best.
