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 South Point, OH
Stabilizing Cracking, Tilting Foundation Walls in South Point, OH

Not long after purchasing and moving into his new house, a homeowner in South Point, OH, discovered structural issues the previous owner failed to disclose. One of the foundation walls was cracking and slightly tilting inward.

The homeowner was greatly concerned by these problems, and he wanted to have them fixed before any serious damage resulted. He researched how to best address these issues, and he contacted Ohio Basement Authority after learning about our company through resources like Home Advisor.

After meeting with one of our inspectors who completed a thorough evaluation of the home, the owner was eager for one of our crews to install a reliable foundation repair solution. Several structural steel I-Beams were placed on the wall to permanently stabilize it and prevent any further cracking or bowing.

The homeowner is pleased to now have a structurally stable living environment.

Waterproofing a Leaking Basement in South Point, OH
After living in their house for almost 25 years, homeowners in South Point, OH, recently began to notice a glaring problem in their basement. Water was seeping inside during periods of heavy rain, and this resulted in damage to some of their stored items. The homeowners wanted to live in the house for many years, so addressing this issue once and for all was very important to them. They contacted Ohio Basement Authority after learning about our company online, and they were eager to see exactly how we could help them. They met with one of our inspectors who completed a thorough evaluation of the leaking basement, and he then presented the owners with some of our reliable basement waterproofing solutions. One of our crews installed these products that included the BasementGutter interior drainage system and SafeDri Triple sump pump. BasementGutter sits in the sub-floor so it can catch any seeping water from the walls and floor. This water is then directed to the SafeDri Triple sump pump to be pumped out of the basement and away from the home’s foundation. Along with three powerful pumps inside the liner, the pump’s external backup battery ensures the system’s continued operation even if the power goes out. Additionally, FreezeGuards were attached to the exterior sump pump discharge lines to allow water to continue to escape the lines if they freeze or become blocked. The homeowners now have peace of mind knowing these trustworthy solutions have helped them create a safer and healthier forever home.

The inspector was very thorough and knowledgeable. He explained the repair system to me, which was a less invasive choice for repair than other companies provided.

I chose to work with Ohio Basement Authority because of a friend’s recommendation as well as the Home Advisor ratings.

The inspector I met with was very helpful. He took extra time to make arrangements for this project.

The crew was super organized, worked at a rapid pace and finished my basement waterproofing in one day. They were very polite throughout the whole process, and there was nothing left for me to clean up.

Your company was out in this area before, and I chose to work with you because of the value for the money for the work done.

I thought the company representative’s presentation was very good, and the installation crew was courteous. Good work and professionalism from this company.

South Point Customer Testimonial
Paul P.
Chesapeake, OH

The inspector was excellent by first thoroughly inspecting our crawl space, and then quoting how to affordably deal with improving our crawl space.

I chose to work with Ohio Basement Authority because of the professional inspector with valid solutions by an experienced company, as well as a great Better Business Bureau rating and good reviews.

Our clay soil was often challenging to dig through, but the installation crew worked hard and steadily.

The and the production crew deserve the highest ratings — definitely a 10 out of 10!

I have had contact with six different representatives from this company, and all have been extremely knowledgeable and courteous. I highly recommend them!

The inspector I met with, as well as his presentation, was excellent. I chose to work with the company because of the price and the inspector’s knowledge.

The installation crew was extremely courteous. If they thought they might be late, I was kept in constant contact! Their cleanup also exceeded what I expected.

I have had nothing but positive experiences with Ohio Basement Authority.
