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 Alexandria, OH
Carbon Fiber Supports Stabilize Cracking, Tilting Foundation Walls in Alexandria, OH
After living in their house for almost 20 years, homeowners in Alexandria, OH, began to investigate the process of selling their home. Before putting the house on the market, the owners knew the home needed various repairs. This included addressing a foundation wall that was showing signs of failure in the form of various cracks. It also was slightly tilting inward. This concerned the homeowners, and they wanted to address these issues so the next owners would not have to worry about them. After learning more about Ohio Basement Authority online, the owners were eager to contact us for a permanent solution. They were equally excited for one of our expert crews to install one type of our many reliable foundation repair products. We installed several Carbon Fiber supports on the problematic foundation wall. These heavy-duty supports permanently reinforce the foundation wall where they were installed, as well as prevent any further cracking and inward bowing. They also can easily be concealed by paint or drywall. The homeowners now have peace of mind knowing this trustworthy solution has helped create a safe and stable living environment for the next owners.
Crawl Space Encapsulation and Insulation in Alexandria, OH
After moving into her house, a new homeowner in Alexandria, OH, began to roll up her sleeves and tackle various repair projects to maintain the 125-year-old house. This included addressing the nasty crawl space. This area underneath the house was full of debris and failing insulation. Concerned the condition of the crawl space could affect the health of the rest of the house, the owner began to research possible repair options and companies. She was eager to contact Ohio Basement Authority for a permanent solution, and excited for us to transform her home’s crawl space. We did this by first removing the nuisances from the crawl space, then encapsulating the area in CrawlSeal liner. CrawlSeal is a thick and durable liner that is similar to swimming pool liner. It fully isolates the crawl space from the earth, serves as a moisture and vapor barrier, and helps insulate the crawl space. We further insulated the crawl space by installing ExTremeBloc insulation panels on the walls and applying spray foam insulation to the band joists. The crawl space is now properly sealed and insulated, and the homeowner is happy to have a healthier living environment because of this reliable repair process.
Dehumidifier Creates a Healthier Work Environment in Alexandria, OH

He then he met with one of our experienced inspectors who completed a thorough evaluation of the property. The owner was eager to have one of our expert crews install the dehumidifier in the basement of the building. This powerful, yet energy-efficient system cleans and filters the air and helps control moisture and humidity. Unlike conventional dehumidifiers, the dehumidifier self-drains so no buckets have to be emptied. The owner, his employees, and his clients can now breathe easier knowing this reliable product has helped him create a healthier environment.

IntelliJacks Stabilize Sagging Floors in Alexandria, OH
Upon purchasing their house, homeowners in Alexandria, OH, were concerned with the structural stability of the aged building. The home was built in 1890, and it was common to use wooden support systems at that time. Wood can easily rot and fail, and so can other improper support systems that were intended to help correct any foundation failure. The light-duty metal jack posts in the basement and crawl space also were rotting, corroding and failing. With the assistance of their general contractor, the homeowners reached out to Ohio Basement Authority with the goal of stabilizing sagging floors in the home. After one of our experienced inspectors completed a thorough evaluation, he recommended one of our many reliable foundation repair products be installed. The homeowners were eager for one of our expert crews to install 30 IntelliJacks in the basement and crawl space areas. Unlike typical jack posts, the heavy-duty IntelliJacks are made of galvanized steel to enhance their durability. This also makes them rust and corrosion resistant. The IntelliJacks permanently stabilize the above floors and help raise them back to the proper level. They also are designed to prevent further settling. But if any settling occurs, the IntelliJacks can easily be adjusted. Now the homeowners can rest easy knowing these reliable repairs have helped them create a safer and structurally sound living environment.
Wall Anchors Stabilize, Straighten Cracking, Titling Walls in Alexandria, OH
After living in his house for 18 years, a homeowner in Alexandria, OH, noticed one of the foundation walls was cracking and tilting inward. The owner was worried these problems could further worsen and lead to safety and structural problems. After learning about Ohio Basement Authority, the owner was eager to contact us to learn more about how we could help him. He met with one of our inspectors who completed a thorough evaluation of the problematic foundation walls, including measuring the walls for movement. Our inspector then presented the owner with one type of our many reliable foundation repair solutions. One of our crews then installed several Wall Anchors on the failing foundation wall. These heavy-duty, galvanized steel anchors permanently stabilize the wall, prevent any further cracking or inward bowing, and offer the best opportunity to straighten the wall because of their unique design. The owner is pleased these trustworthy repairs were completed to ensure the safety and stability of his home.

The inspector I met with was very professional and gave a great presentation, explaining all the options and advantages of your system. A friend had a bad experience with another company, so after your inspector's I didn’t feel the need to talk to any other company.

The installation crew called in advance to let me know they were on their way. They checked with me before leaving to make sure I was happy with the cleanup.

The entire experience was wonderful from start to finish. I was very impressed with everyone I came in contact with, and their work was fantastic.

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!

Mark & Will
Johnstown, OH
When Mark H. was trying to sell his house in Johnstown, OH, he knew that the crawl space with its structural problems would render the property quite difficult, if not impossible to sell. During the process of putting the house on the market, a home inspector came to take a look at the problem. He recommended that Mark should have it fixed as soon as possible, and referred him to Ohio Basement Authority. Mark was very impressed with the options offered by the company to safely and effectively restore the structural integrity of the foundation with specialized crawl space jacks called IntelliJacks. To expedite the process so that Mark could sell his property quickly, Ohio Basement Authority was willing to perform all the work in the middle of the winter and under cold temperatures. Mark was very grateful for that. The home sold shortly after the repairs were finished. The new owner, Will C., is also very happy because he bought a home with brand new foundation work that is backed by a Transferable Lifetime Warranty. He will have the peace of mind of knowing the crawl space is structurally safe for as long as the house stands!

Linda and Donald N.
Granville, OH
We feel compelled to write you regarding our recent experience with your company. Mainly the words professional, integrity and solid product come to mind. We live in Granville and our lot sits low. We built this home 21 years ago and have two sump wells, which we have maintained throughout the years. We've only had water in our 2,500 square foot, unfinished basement once, and that was enough. The original pumps were Zoeller.  After eight years or so, they wore out and we began the 13-year flurry of sump pump “hell.” We went through many products and many exchanges and replacements of battery back-ups. We are diligent about checking battery charge/water levels and replacing pumps/switches at the first sign of any system distress. We are "in tune" with what is going on in our basement. We travel a lot and want confidence that we won't come home to a disaster. We have endured several extended power outages – some lasting 7 to 10 days – where we have had back-up batteries attached to our back-up battery. We even ran back and forth to a truck stop to keep those charged through these outages. We were weary and lacked confidence in our efforts. Our ultimate goal was to put the SafeDri Triple Sump product in the main sump pump well and move the other battery back-up system to the second sump pump well. We finally have accomplished that goal. We had looked at it for years with another company, then attended the remodel expo this past winter and found it at Ohio Basement Authority’s booth. Then one of your inspectors came out and made a thorough and professional presentation, and we set up an installation date. The crew members were professional, hard-working, respectful of our home, and put in an entire 8-hour day to install our new system and move the other back-up battery. They totally cleaned up their work area and disposed all debris. Even though there were several "snafus" that surfaced immediately afterward, this is where your staff really shined! Our older back-up battery alarm began beeping the very next day in clear, sunny, dry weather. We called your office and, on a Saturday,  your service tech came out to fix the float switch. The next day, the new SafeDri Triple Sump began to beep. That Monday, I called the office, and they handled it with immediate consideration and true empathy and sent the tech back out that very day. He troubleshot that evening on the new system for three more hours. He then returned two days later and reworked the install. It has been operating as expected ever since. He provided the complete confidence and thorough explanations we expected and needed. We felt he knew exactly what he was doing and he did it! He is terrific! In this case, all your staff made us feel like all that was really important was that everything was done properly and attended to as soon as possible. We never felt like we were going to be “hung out.” For these reasons, we feel that you and your company will be there for us in the operation of this product, and that we made the right choice. We always knew that the SafeDri Triple Sump was the way we wanted to go, but the install and warranty is the most important part of the story. You should be proud and really value the people who work on your behalf. They represent you well!
