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!

We chose to work with Ohio Basement Authority because of the reviews of past customers and our online research of products.

The inspector we met with was very thorough and answered all our questions to our satisfaction. He spent a considerable amount of time here to make sure we were comfortable with our decision.

The installation crew arrived at the expected time on both visits, and they were extremely courteous and friendly. They did an excellent job with debris removal and cleanup.

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.

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!

The inspector I met with was very professional, and I chose to work with Ohio Basement Authority because of the lifetime warranty.

Ryan and Drew with the installation crew are top-notch guys. They were extremely hard workers and very professional. They even took time to let my 7-year-old son “help.” I was very impressed. They did a great job.

I found Ohio Basement Authority on the Internet, and decided to go with the company after seeing reviews. Also because the inspector explained everything going on with my foundation, and showed me and my wife.

The staff was very courteous. I was very impressed. They remembered what shift I worked and contacted me at appropriate times.

The inspector, as well as the installers, did a great job showing and explaining things.

I am very pleased, and will definitely recommend the company.
