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 New Plymouth, OH
Keeping a Leaking Basement Dry in New Plymouth, OH
Homeowners in New Plymouth, OH, have lived in their house since it was built 67 years ago. They recently discovered a glaring problem in their basement that they wanted to address right away. Water was leaked inside and leading to visible damage. After voicing their concerns to a trusted friend, their friend recommended contacting Ohio Basement Authority for assistance. The owners did so, and they were eager to meet with one of our inspectors. Our inspector completed a thorough evaluation of the basement, and he then presented the owners with some of our reliable basement waterproofing solutions. One of our crews then waterproofed the basement with the BasementGutter drainage system and SafeDri sump pump. Any seeping water from the walls and floor will be intercepted by the BasementGutter system, which was installed in the basement’s sub-floor. This water is then directed to drain into the SafeDri to be pumped out of the house. The SafeDri features two powerful pumps inside its liner, as well as an external backup battery. The homeowners now have peace of mind knowing these trustworthy solutions have helped them create a healthy, safe and dry living environment.
Waterproofing and Structurally Stabilizing a Home in New Plymouth, OH
After she recently acquired a house, a homeowner in New Plymouth, OH, wanted to have various repairs completed. This included addressing the leaking basement and cracking foundation walls that also were slightly tilting inward. The homeowner began to research how to best address these issues, and she contacted Ohio Basement Authority after learning more about our company online. After meeting with one of our inspectors, the owner was eager for one of our crews to install the perfect repair solutions. We waterproofed the basement by installing the sub-floor BasementGutter interior drainage system and SafeDri super sump pump. Any seeping water will be intercepted by the BasementGutter system and directed to the SafeDri. From there it is pumped out of the basement and away from the home’s foundation. A FreezeGuard also was attached to the exterior sump pump discharge line. Several IntelliBraces were placed on the problematic foundation walls. These heavy-duty beams permanently stabilize the walls and can be tightened for potential wall improvement. Other support beams can fail and corrode, but IntelliBrace beams are zinc coated so they will never rust, corrode or fail. The homeowner now has peace of mind knowing these reliable repair solutions have helped create a safe and healthy living environment.

The inspector’s presentation was just right. He answered my questions and didn’t oversell or get pushy.

I then chose to work with Ohio Basement Authority because of the company’s professionalism and the belief that I was working with a larger organization that had a great reputation.

Other than the work performed, there was no clue your crew had been there. They worked quickly, professionally, and left no mess. Their use of the plastic wall to control dust was especially appreciated. Martin with the crew also was very nice.

I would call your company first if I ever needed additional services.

The company representative I met with was very helpful and professional, and he answered all my questions.

I chose to work with the company because of the thoroughness of the inspection of the issue, the inspector’s explanation of the cause and cure, and why his fix would be better than any other type.

The foundation had a broken corner, due to settling. The work was to raise the foundation of the entire side of the house. The crew was very professional and easy to work with. They stayed to do the job right, even though it took a day longer than expected.

I really liked the thoroughness and the extra time they took to do the job right.

Prior to doing research about basement repair companies, I never paid attention to those types of businesses.

We interacted with two companies, one of which was Ohio Basement Authority. There is a consistency in every interaction with members of your team from the inspector to the service support via telephone, to the installation crew on site.

We chose Ohio Basement Authority because your inspector spoke to us in a cordial manner that established trust and displayed a level of expertise, and because he followed up with us. He was very detailed in his explanation of possible service options.

It was a long drive from Gahanna to Athens each day, but Drew was always clear and accurate with the start time for each of the three days. Each member of the crew was an extension of your staff of inspectors, providing helpful insight about the process along the way. Drew was an excellent leader of his crew and ambassador for your company.

I will certainly keep Ohio Basement Authority in mind if I come across friends or neighbors that need basement repair work.

I was looking on Angie’s List and they contacted me, and I decided to at least talk to them and get an estimate. The inspector’s presentation was very informative and he answered any questions we had. My husband decided to go with them after the presentation.

I chose to work with Ohio Basement Authority because of the knowledge displayed by the representatives and the thorough printed documents left behind to review. I’ve also seen the company’s TV commercials, and we’ve had work done by them at our primary residence in Worthington. They were very helpful and thorough both times.

The office staff was courteous and helpful, and they kept us connected to the appropriate people whether it was getting back to the inspectors or the production staff.

The installation crew was very prompt, and I believe they called in advance to say when they were arriving. All three of them were very nice and friendly, and did whatever they could to please us and do a good job. The clean-up also was excellent.

I heard about Ohio Basement Authority through Angie's List, and I chose to work with your company because of the great reviews I saw online. I also liked the breakdown of the pricing on the products you install so you can see exactly what you are paying for instead of a lump sum cost.

The foreman and the crew were very courteous. He and his crew explained the installation process and went over the job to make sure everything that they had on their paperwork was correct at the beginning before starting the work.

They were always making sure there wasn't any dust getting into my living area. They also answered any questions I may have had about any of their products or the installation process. They went above and beyond everyday cleaning up any work debris.

If I have any more work that I need done in the future, Ohio Basement Authority will be the first one on my list. Also, it is very nice to see such a hard working group of people who seem to enjoy the work that they do, and take pride in the work they do.

There’s no doubt that our inspector was part of our decision to work with Ohio Basement Authority. He was very professional and knew his product from A to Z. The BBB was also part of our choice, as well as the overall plan as to what was needed and how it would be done.

The crew was great. Each member introduced themselves and shook hands as soon as they arrived. They were friendly, and each knew their job very well. They even were really good with our canine friends who are always in the way.
