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!

Job Stories From London, OH
A Leaking Basement in London, OH, Will Be Dry Because of BasementGutter and Safe Dri Super Sump Installations
Upon moving into their house in London, OH, homeowners noticed large puddles collecting in the basement corners whenever it rained. While this has not caused significant damage, the owners want to make sure their longtime home always will be safe and dry. They contacted Ohio Basement Authority after learning more about our company on our website. We installed patented and reliable waterproofing products including the sub-floor BasementGutter drainage system and a SafeDri Super Sump pump to keep the basement free of water. If any water seeps into the basement, the BasementGutter system will intercept it and drain it to the SafeDri Super Sump. From there, it will be pumped out of the basement and away from the foundation through a discharge line attached to new downspout conductor lines that were also installed. The sump pump was installed inside the larger SafeDri Triple liner, should the owners choose to upgrade the sump pump in the future. The homeowners now have peace of mind knowing their house will be a healthier living environment for many years to come.

The homeowners contacted Ohio Basement Authority after learning more about our company on our website. We installed one of our many foundation repair products. Several heavy-duty Carbon Fiber wall supports that will permanently stabilize the problematic foundation wall and prevent further cracking and bowing. These durable supports can also be concealed by drywall or paint. The owners now have peace of mind knowing their home will be structurally stable for many years to come.
Crack Repair on a Leaking Foundation Wall Will Keep a Basement Dry in London, OH

After recently moving into his house, a homeowner in London, OH, started to notice water entering the basement through a crack in the poured concrete foundation wall.

Hoping to keep his basement dry for good, he contacted Ohio Basement Authority after learning more about our company and our services through our website.

To address this issue and prevent water from seeping through the wall crack, we first excavated the area outside the problematic wall. The crew dug down to the footer and filled the cracks. Then Carbon Fiber was applied to the wall to seal the crack as well as stabilize the wall. The soil was then replaced as the project was completed.

The homeowner is happy the wall will no longer leak so his home will be a healthy living enviornment for many years to come!

Crawl Space Encapsulation and Stabilization Creates a Healthier, Safer Home in London, OH
A homeowner in London, OH, moved into her house less than one year ago, and she was recently starting to notice some structural problems. Along with some wall cracking, she noticed some areas of the floors were out of level. These are telltale signs of foundation settlement and a failing support system, and the homeowner wanted to address them right away before they turned into serious problems. We installed some of our many reliable crawl space repair products. Eight IntelliJacks were installed to permanently stabilize the main girder and floor joists in the crawl space. These heavy-duty supports are designed to stop settling and sagging and raise the floors back to level. They also can easily be adjusted if any settling occurs. We also removed the debris and failing insulation in the crawl space, and completely encapsulated it in CrawlSeal liner. This durable liner isolates the home from the earth, serves as a moisture and vapor barrier, and helps insulate the crawl space. The homeowner now has peace of mind knowing these permanent solutions have helped create a healthier and safer living environment she will be able to enjoy for many more years to come.

They contacted Ohio Basement Authority after learning more about our company and our services through our website. We then installed some of our many reliable basement waterproofing products.

These systems then direct the water to the SafeDri sump pump, which safely and effectively pumps the water out of the basement and away from the foundation.

Properly Sealing a Crawl Space in London, OH
A homeowner in London, OH, has lived in her house for several years. She rarely ventures into the crawl space, but a recent peek inside this area under her house revealed some issues.

This thick and durable liner, similar to swimming pool liner, completely seals the crawl space to isolate it from the earth. CrawlSeal also acts as a moisture and vapor barrier, and it helps insulate the crawl space. Additionally, the older sump pump was removed and replaced with the more reliable SafeDri sump pump system. The homeowner now has peace of mind knowing these trustworthy repairs have helped her create a healthier crawl space and home.

The owners wanted to address these issues before they resulted in more damage to their house, so they began to research how to best fix the problems. They found information about Ohio Basement Authority online, and they were eager to contact us to learn more about how we could help them. One of our inspectors evaluated the condition of the support system in the crawl space below the house, and he found improper, failing, bending supports. He then recommended the perfect repair solution. One of our crews installed several IntelliJack supports underneath a new steel supplemental support beam. 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. The homeowners are pleased to have a more reliable system supporting their house.

Updated Exterior Drainage Will Help Keep a Home Dry in London, OH

After living in their house for two years, homeowners in London, OH, noticed a problem with their exterior drainage system.

The owners wanted to have this issue addressed before water ended up in their basement. They knew they could count on Ohio Basement Authority because we completed a foundation repair project for them around the time they moved into the house. The owners were eager to again meet with one of our inspectors to learn more about how we could help them. Our inspector evaluated the condition of these exterior drainage systems and he recommended some upgrades.

One of our crews then installed new reliable downspout conductor lines and exterior sump pump discharge line on the property. These lines were placed in the ground and directed far enough from the home’s foundation so the water from the lines would not seep inside the home. A YardWell outlet also was used to conceal the end of the line in the yard.

The owners are happy to have an updated exterior drainage system that will help keep their home dry.

Waterproofing and Encapsulating a Nasty Crawl Space in London, OH
Not long after moving into her house, a homeowner in London, OH, noticed problems that could negatively impact the health of her home. Once she ventured into the crawl space under the home, she found the area was filled with debris, standing water, and moldy and failing insulation. Whatever is in your crawl space air is in your house and affecting you. This is because of the stack effect. Air in the crawl space is drawn up through the house in an airflow pattern from bottom to top. This concerned the homeowner, so she wanted to address and fix these problems right away. She contacted Ohio Basement Authority after learning more about our company online, and was eager for us to fix the nasty crawl space for good. We did this by waterproofing and encapsulating the crawl space. To address any seeping water, we installed the CrawlDrain drainage system and SafeDri sump pump. The CrawlDrain system will intercept the water and direct it to the SafeDri, where it is then pumped out of the crawl space and away from the home. Exterior drainage solutions included a FreezeGuard attached to the sump pump discharge line, new downspout conductor lines, and YardWell outlets attached to the ends of two of the downspout conductor lines. The crawl space was encapsulated in CrawlSeal liner to isolate it from the earth. It also serves as a moisture and vapor barrier and helps insulate the crawl space. The dehumidifier also was installed to control humidity and reduce odors, and exterior vent covers further seal off the crawl space from the elements and pests. The homeowner is pleased these many reliable products were installed so her home will be safer and healthier for many years to come.
Waterproofing and Foundation Repair Correct a Leaking Basement in London, OH
After living in their house for almost 10 years, homeowners in London, OH, recently noticed water seeping into their basement during heavy rains. It would enter through a corner with a pilaster, or column attached to a wall, that was beginning to crack. The owners wanted to make sure their home would be free of water and prevent additional damage to flooring, carpet and their belongings. They contacted Ohio Basement Authority after learning more about our company through websites like Angie's List. One of our expert crews first removed the older, failing pilaster, then completely rebuilt it with new concrete block. The sub-floor BasementGutter drainage system was then installed in this problematic area to catch any seeping water and drain it to the existing sump pump. The homeowners were pleased these projects were completed so their forever home will be a safe and healthy living environment for many years to come.
Waterproofing Products Like SafeDri and BasementGutter Keep a Home Dry in London, OH
After four years of living in their house in London, OH, homeowners began to notice water coming in through the garage area. A desk and some carpeting was damaged by the water intrusion, and the owners wanted to find a permanent solution to keep the home dry and prevent further damage. They contacted Ohio Basement Authority after looking at our company's website, and we installed various waterproofing products. These included the BasementGutter drainage system that will intercept any seeping water, and the SafeDri triple sump pump that will pump any water out of and away from the foundation. New downspout lines were also buried underground, and an outlet was attached to camouflage the end of the line. The homeowners now have peace of mind knowing these reliable products will keep their home dry for many more years to come.  
Radon Mitigation System Helps Create a Healthier Home in London, OH
They have lived in their house since it was built 10 years ago, but homeowners in London, OH, were ready to sell their house. They wanted to take the proper steps to ensure the home’s health and resale value, so they wanted to address the levels of radon in the house. Radon is a naturally occurring gas that is present throughout the country. It is a product of uranium decay in rocks and soil. Radon also is a very dangerous gas that has been linked to more than 20,000 deaths a year. It is the second leading cause of lung cancer, and it is particularly hazardous for smokers and former smokers. Radon is colorless, odorless, tasteless, and difficult to detect without the proper testing. The homeowners contacted Ohio Basement Authority, and we tested their house for radon. The results indicated the radon level was 7 pCi/L (picocuries per liter). This is slightly higher than the level at which radon mitigation systems are recommended for homes, which is 4 pCi/L. The homeowners wanted to take the proper steps to make sure the house would be healthy, so we installed a radon mitigation system to safely pull radon from the home and ventilate it outdoors. The homeowners were pleased this reliable system was installed so the house will be a safer and healthier living environment for the next owners.

Everyone we spoke to was very courteous. My husband and I were anxious about hiring a contractor due to some of the stories we have heard, but within the first few minutes of speaking with your people we knew we were with the right company.

We chose to work with Ohio Basement Authority because of John’s dedication to the company, referring to them as “family,” and the time he took to measure and educate us on the procedures that needed to be done. After viewing three other presentations, there was no doubt that John was far and above the rest because of his professional assessment of our needs and his explanation. Plus the publication we received prior to his visit was great.

The crew arrived on time, and we were kept advised of the time they would be here. They also were very courteous. The foreman and his crew were superb. The clean-up also was very nicely done. My husband says they should all get a nice raise.

We will always feel good in recommending your company.

London Customer Testimonial
Forrest B.
West Jefferson, OH
The sump pump in Forrest B.'s West Jefferson, OH, home was just not handling its job very well. It seemed to go out every time there was a heavy rain storm. He often found himself rushing to the hardware store to purchase another pump to protect his basement. He started to do some research, looking for solutions for this ongoing sump pump problem. He found Ohio Basement Authority, installing the exclusive SafeDri Triple Sump Pump System. Looking at the system, Forrest knew that if he was to have a dry basement and never worry about sump pump problems again, he needed the SafeDri Triple Sump. This system has two backup pumps, including a battery operated unit that will keep the basement dry in case of a power outage. Forrest was very pleased with the entire experience. "The office staff was very helpful and courteous," he said. "I didn't have a lot of contact with them, but when I did they were very polite. From the inspector -- who thoroughly evaluated the property, explained the problem and provided Forrest with a choice of solutions -- to the installers who worked quickly, showed up on time and cleaned up after themselves so well, no one could tell that they have been there working. "Jim's presentation and attitude is what helped me make the decision to have Ohio Basement Authority complete the job," Forrest said. "He didn't try to pressure me into going with his company. I would definitely recommend Ohio Basement Authority to anyone considering having changes made to their sump basin or if they need outside drainage installed."

The installation crew arrived on time, ready to go to work. The foundation repair took three days, and the crew worked hard all three days to complete the fix. Joe and his crew were very courteous, and they did a good job on the clean-up.

The BBB rating and the extensive information on your website concerning French Drain systems and similar products/methods is why I chose Ohio Basement Authority.

Galloway, OH
Karen B. has lived in her home in Galloway, OH, for several years. She was getting tired of dealing with a smelly basement and crawl space, as well as the lack of storage. She contacted Ohio Basement Authority to see how to remedy these issues, and we installed the perfect solution for her. We encapsulated the partial crawl space in CrawlSeal liner and added ExTremeBloc insulation panels to the crawl space walls. Karen is excited this area is now a brighter, warmer, and healthier space she can finally use for storage.

Ohio Basement Authority was the only company I called.

The inspector I met with was a very nice man, and his presentation was very good. He was not pushy. He just gave me the information and was very thorough.

The lead foreman onsite also was very good and informative. He answered all my questions and was very professional. He is a great representative for your company! All three guys were very nice and explained things when I had questions.

I’ve seen Ohio Basement Authority on TV and at home shows. I chose to work with the company because of the good salesman, and I was not happy with another company or their repairs.

The company representative I met with was knowledgeable, and his presentation was very well done.

The crew arrived on time, was courteous, and cleaned up well. I’d rate them all 10+.

I will use your company again. Thank you.

We’ve seen your TV commercials, and Ken Sperry of Thompson Builders referred us. We chose to work with you because of Ken’s explanation of how you could reinforce our walls.

Zeke Fowler was the representative who inspected our basement walls. He was very detailed and he explained the findings, materials, installation process, price and timeline of completion. All of our questions were addressed.

Valentin, Jesus, and Arturo were very respectful and organized, and their cleanup was impeccable. Gail is unable to go to the basement, and she was shown photos and given updates. We would be pleased to work with them again.

The members of the production crew were all very professional. They explained what they were going to do, asked if I had any questions, and showed me everything when they were finished. They were so considerate and were good about not leaving a mess, which I really appreciated. They were personable, super-nice people.

I chose to work with Ohio Basement Authority because of the company’s BBB ratings and the inspector’s evaluation and visit with me was much better than the other one I received. My inspector did a good job letting me know what was wrong with cracks in the basement and how to correct them.

The installation crew was very nice and worked hard all day.

I’m glad to get the problem solved and won’t have to worry about it anymore. I didn’t want to leave any issues for my kids to have to handle, or have a major issue to take care of when I decide to retire.

Victor arrived early for the initial consult. He was very professional and knowledgeable. He gave me a fair estimate and got the repair scheduled before the end of our appointment. He is a great rep for your company.

Matt and his crew were really friendly and worked quickly to make the repairs.

I had a great experience with your company.

We’ve seen your commercials on TV and a reference for you on the radon website. We then chose to work with you because of your BBB reviews and the role you play in the radon organization.
