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 Portsmouth, OH
Basement Waterproofing and Foundation Repair in Portsmouth, OH
As they moved into their house, new homeowners in Portsmouth, OH, noticed some issues they wanted to address. Water intrusion and damage were obvious, as were cracks on one of the foundation walls. While searching for the best repair options, the homeowners came across Ohio Basement Authority’s information on Angie’s List. They were eager to contact us and meet with one of our inspectors. After assessing the condition of the leaking, cracking basement, our inspector recommended our reliable basement waterproofing and foundation repair solutions. We installed the BasementGutter interior drainage system and two SafeDri sump pumps to keep the large basement dry. Any water intercepted by the BasementGutter system is directed to the SafeDri and then pumped out of the basement and away from the home’s foundation. FreezeGuards were attached to the exterior sump pump discharge lines, and a YardWell outlet was used to camouflage the end of one of these lines in the yard. Several IntelliBrace beams also were installed to permanently stabilize the cracking, tilting wall. These unique beams can be adjusted during dry seasons to improve the wall’s condition. The homeowners are pleased these trustworthy solutions were installed to help them create a safe and healthy living environment.
Basement Waterproofing with BasementGutter and SafeDri in Portsmouth, OH
Homeowners in Portsmouth, OH, noticed a lot of water would seep into their basement every time it rained heavily. They spent a lot of money to clean it up, but it continued to be a problem. They contacted Ohio Basement Authority, and one of our expert crews installed the BasementGutter Basement Waterproofing drainage system and SafeDri Triple Sump Pump System in the basement. BasementGutter was installed in the sub-floor to catch any seeping water and drain it to the SafeDri Triple sump. Water is then pumped out of the basement and away from the home. The SafeDri Triple sump features three pumps, including a battery back-up pumping system that ensures the home will be protected even in a power outage. The homeowners are happy to have a basement that will be dry and healthy for years to come.
CrawlSeal Encapsulation and Other Installations Improve Health of a Crawl Space in Portsmouth, OH
After Ohio Basement Authority previously installed several Helical Piers to correct foundation issues for a homeowner in Portsmouth, OH, the customer did not hesitate to call us again when he noticed issues with his crawl space. The unhealthy area full of debris and failing insulation was completely transformed and improved by several crawl space repair products installed by one of our expert crews. These permanent solutions included CrawlSeal liner, ExTremeBloc and insulation, CrawlDrain drainage, SafeDri sump pumps with back-up batteries, dehumidifier, exterior vent covers, crawl space access door and FreezeGuards. The homeowner was excited to have these products installed in his house so that it will be a healthier living environment for many years to come.
IntelliBrace System Stabilizes Garage Wall in Portsmouth, OH
A homeowner in Portsmouth, OH, recently began to notice one of the foundation walls in the garage of his bi-level house was cracking and bowing inward. He was concerned with the structural integrity of the wall, and hoped to find a permanent solution to stabilize it. He contacted Ohio Basement Authority, and one of our expert crews installed the IntelliBrace System. A total of five heavy-duty, zinc-plated steel beams were tightly secured against the problematic wall. These beams will stabilize the wall in its current position, and they can be tightened over time for possible wall improvement. The homeowner now has peace of mind knowing his home will be a safe and stable living environment for many years to come.
Stabilizing a Settling Garage Foundation with Push Piers in Portsmouth, OH

During the 12 years he has lived in his house, a homeowner in Portsmouth, OH, kept his eye on a potential structural issue. Various cracks in stair-stepping patterns could be seen on the interior and exterior of the home’s garage. This issue can signal foundation wall failure and settlement.

Now that he wanted to sell the house, the homeowner knew he needed to address these issues for safety and resale value purposes. He contacted Ohio Basement Authority after learning more about our company online, and one of our inspectors presented him with the perfect solution.

We installed several Push Piers underneath the settling garage walls. These heavy-duty, galvanized steel piers are mechanically driven down to competent soil so they will permanently stabilize the foundation. They also offer the best opportunity to lift the foundation back to level.

The homeowner now has peace of mind knowing this reliable repair process has helped him create a safer living environment for the next owners.

Stabilizing Sagging Floors With IntelliJacks in Portsmouth, OH
A homeowner in Portsmouth, OH, has lived in his house for several years. But it wasn’t until recently that he noticed some areas of the floors felt uneven and like they were sagging. The owner wanted to address these problems before serious damages resulted. He previously worked with Ohio Basement Authority on another repair project, so he knew he could again count on us for the right repair solution. One of our inspectors visited to evaluate the support system in the crawl space underneath the house, and he found these supports were starting to fail. Our inspector then recommended one of our reliable foundation repair solutions. One of our crews then installed several IntelliJacks underneath new steel supplemental support beams in the crawl space. These heavy-duty, galvanized steel supports permanently stabilize the floor joists and help raise the floor back to level. They also will not rust or corrode. They are designed to stop settling, but can easily be adjusted if any settlement occurs. The homeowner continues to be a happy Ohio Basement Authority customer, and he is glad to now have a safe and stable living environment.
The Health and Appearance of a Leaking Basement in Portsmouth, OH, is Dramatically Improved
Water has been seeping into a basement in Portsmouth, OH, recently, and the homeowner was concerned the belongings she had stored in this area could be damaged. She contacted Ohio Basement Authority, and we installed various permanent waterproofing solutions in the basement of the 95-year-old house. These reliable products included the sub-floor BasementGutter drainage system and a SafeDri Triple sump pump. The CrawlSeal Wall System was also added to the walls to improve appearance, prevent water vapor from permeating the walls, and drain wall leaks. The homeowner was pleased these installations were completed so her basement will be a healthier area for many years to come.

BasementGutter, SafeDri, & CrawlSeal Create Healthier Basement in Portsmouth, OH
Homeowners in Portsmouth, OH, wanted to sell their home, but first needed to address a significant basement leakage issue. They tried "do it yourself" waterproofing methods that proved to be ineffective because water was still seeping into the basement. They contacted Ohio Basement Authority, and one of our expert crews installed the sub-floor BasementGutter drainage system around the basement's perimeter. The BasementGutter intercepts any water and drains it to the SafeDri Prox sump pump. The SafeDri pumps the water out of and away from the home through a discharge line. An FreezeGuard was attached to the exterior discharge line to prevent flooding if the line freezes or becomes blocked. A back coal room in the older home's basement was also encapsulated in CrawlSeal liner. The durable liner was completely sealed over the floor and walls to fully isolate the home from the earth. The result is an attractive, bright, tough, impervious liner, and a healthy home! The homeowners are pleased to have a healthier basement that will be dry for future owners for many years to come.
Waterproofing Installations Correct a Wet Basement in Portsmouth, OH
A homeowner in Portsmouth, OH, recently noticed puddles of water in her basement during periods of rain. She wanted to address this issue before it resulted in damage to her belongings, so she contacted Ohio Basement Authority. We then installed various permanent waterproofing solutions in the basement of the more than 90-year-old home. These included the BasementGutter drainage system, a SafeDri Triple sump pump, and a dehumidifier. LumaBright panels were also installed on the walls to assist with waterproofing and improve their appearance. The homeowner now has peace of mind knowing her house will be a healthier living environment for many years to come. Waterproofing Installations Correct a Wet Basement in Portsmouth, OH - Photo 1

My sister-in-law hired Ohio Basement Authority for her wet basement and was happy with the results, so she referred me to you.

The representative that came for the inspection was very professional and easy to talk to. He explained the products and the lifetime warranty, and I was sold.

The installation crew was very courteous and always made sure everything was to my liking. They updated me on their progress every step of the way and made sure they had cleaned up sufficiently when they were done.

I chose to work with Ohio Basement Authority because of the positive Angie’s List and BBB presence. The inspector I met with did a good job explaining the process, and the installation crew did a great job. The crew was full of very hard workers who were professional, did a super job, and represented your company well. They also did a great job cleaning up. I could not even tell they were here.

Davida F.
Portsmouth, OH

Victor is a fine gentleman, and he really went above and beyond the call of duty in providing the estimate.

Not only was Victor on time, but he was a bit early. I must say that he was very, very polite, knowledgeable, and informative. Answers were provided in a manner that I could understand, and he even worked to cut costs where appropriate. I think that Ohio Basement Authority has a true asset in Victor. I would like to extend a special thanks to him and the company for the time and energy expended during the process.

I felt that the booklet made it possible for me to understand more thoroughly the process involved and options available for the waterproofing process. I very much appreciate the pre-visit educational materials.

I had notes in hand and addressed them with Victor prior to the inspection. We discussed them afterward and the estimate was developed based on the priorities at hand. The pre-visit information assisted me in developing the list, as well as questions raised by my brother who is in the construction business. Victor thoroughly addressed each issue.

Victor even went to the extent of reviewing his photographs after leaving and contacted me with possible cost saving ideas. I'm telling you he is a true treasure.

Development of the estimate took some time, as quite a few issues were being addressed. I really do appreciate the time and energy Victor gave throughout the process.

You guys did a great job. I will definitely get you more business in my area, especially on my jobs.

I will definitely give Ohio Basement Authority the highest possible review any way that I can. I believe the pricing for the work you guys do is a great deal. It is far better than total replacement.
