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 Nashport, OH
Stabilzing Cracking, Settling Walls in Nashport, OH

Since moving into their house almost 20 years ago, homeowners in Nashport, OH, have been keeping an eye on potential structural issues. Two of the walls in the home’s attached garage were cracking. One of these walls was in worse shape, as mortar was missing and daylight could be seen through the stair-step cracking patterns. The latter issues indicate foundation settlement.

Not only were the homeowners concerned with the stability of the garage, they were worried these problems could negatively impact their ability to sell the house in the near future. They began to research how to best address these issues, and they contacted Ohio Basement Authority after learning more about our company online. After meeting with one of our inspectors, the homeowners were eager for one of our crews to install our reliable foundation repair solutions.

These included several Carbon Fiber supports on the less severe wall. These heavy-duty supports permanently stabilize the foundation wall where they were installed, and they prevent any further cracking or inward bowing.

Several Helical Piers also were installed underneath the other wall. These durable galvanized steel piers were mechanically driven down to competent soil and attached to heavy-duty foundation brackets on the garage’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.

The homeowners now have peace of mind knowing these trustworthy repairs have helped them create a structurally sound home.

Updated Exterior Drainage Will Help Keep a Basement Dry in Nashport, OH
After living in their house for one year, homeowners in Nashport, OH, started to notice a problem in the basement. There was visible evidence of water intrusion and damage in a few corners, which also happened to be in the same area as exterior gutter downspouts. The owners wanted to avoid having to deal with flooding and similar damage, so they began to research potential repairs. After finding information online about Ohio Basement Authority, the owners were eager to contact us for further guidance. They met with one of our inspectors who completed a thorough evaluation of the home and its drainage. Our inspector then recommended updating the exterior drainage system. One of our crews then replaced the lines with newer, thicker pipe used for the downspout conductor lines. These lines were placed in the ground and directed to drain water to a hillside the edge of the property. The homeowners are pleased to now have an updated exterior drainage system that will help keep their home dry.

A friend who is a satisfied Ohio Basement Authority customer recommended you. I’ve also seen your TV ads.

The inspector did a great job of explaining everything. He was courteous and represented your company well. The crews were wonderful. I could not believe how much work three people could accomplish in one day!

Prior to contracting with you to do work, I had seen your truck in the neighborhood. I then met with Jeff Floit, who was knowledgeable, courteous, helpful in choosing a solution, and excellent on follow-up.

I chose your company because of the knowledge of Jeff Floit, the lower cost, and a better, more comprehensive solution.

I’ve had two contracts for work with you over the past two months, and both crews were excellent.

I’ve seen Ohio Basement Authority’s commercials and heard about the company through word of mouth, and I chose to work with you because of your courtesy and cost.

Travis was professional and knowledgeable. He answered my questions in a respectful manner.

All members of the crew were professional. They fully explained what they were doing and how the drainage system they installed would work. Excellent job! There’s no evidence that they had even been here, except for the wet cement.

From start to finish, your representative and crew made this a positive experience! Even better, this has been an extremely wet few days and I can see/hear the sump pump and drainage system doing their job to keep my basement dry. THANK YOU!!!

I chose to work with Ohio Basement Authority because of the company’s reputation with the Better Business Bureau.

Dave and his crew were very polite and knowledgeable, and they completed the install in a short time. I’m very happy with the installation, and I hope it works to eliminate the radon gas issue.

I hadn't heard of Ohio Basement Authority until I searched Google for repair options.

The inspector I met with did a great job selling your product, answering questions, and assuring me that the job would be done right the first time. He was the key for us to decide to go with your company. We also liked the price, and you quoted nearly half the price of your competitors.

The office staff was also courteous and helpful. When I called about credit, the gentleman was very helpful and made sure I was first priority. He walked me through the online process and was able to complete my payment.

The installation crew was great! They arrived on time, were very personable, and had a great attitude. They also did a great job cleaning up, and the area looked better than when they started!

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.

Your representative was very nice, and he knew the products he showed me. He explained what would be best for the problem my basement had. I would refer anyone to him if they needed work done.

The company was one of four that was referred to me. I selected it because of the name, Ohio Basement Authority. It is exactly what I needed.

The crew got right to work and was no bother to me.  They even helped me by moving a vehicle for me. Thank you so much for sending me a great crew!

I will let everyone know about your company and how pleased I am with the work that was done on my home.

Zanesville, OH

My wife just happened to take notice of a commercial on TV you had one day. You were the first company we came upon. We checked the Internet with your reputation and checked with the BBB, and we were pleased you had flying colors.

We had a very friendly crew. Drew, the foreman, with Ben and Ryan were awesome. I was on vacation when they were there at the house and chatted with them some while they were working. I was concerned some, as they were working in direct sun for most of the day (in the high 80s low 90s). But they kept working no matter what. My foundation was as thick as 27 inches in some places. They had to dig deep in some places by hand.

They also did a good job cleaning up. They had to dig through a layer of stones that were at one time used for landscaping, and the dirt had some stones in it as well. I was surprised to see where thy raked all the stones back into the backfill area that I will be able to mow without throwing rocks.

My wife and I felt comfortable enough with them to offer them the use of our basement restroom since they had to keep hydrated, and figured they would need to use a restroom. We also said they could have their lunch in the finished part of the basement were it had air conditioning, but Drew said they normally don't eat a lunch. Holy cow!

Beverly W.
Zanesville, OH

Beverly W. had struggled with basement water problems since she first moved into her home in 2000. Her basement would leak badly every time it rained, to a point where she wouldn't sleep well at night or go away on vacation for fear or waking up or coming home to a basement mess.

When she was ready to fix the problem, she called a few different companies for repair estimates. She chose Ohio Basement Authority to handle the job, and she has been very pleased with her decision. The work was completed in only two days. She is happy with the results and the service, and even happier with the fact that the company will be there to make sure her system works efficiently for many years.

"I like the fact that they will be contacting me to set up the yearly inspection," she said. "And I am sure if I have any questions, I can contact them at any time and they will help me over the phone."
