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 Gallipolis, OH
Permanent Basement Waterproofing Solutions Installed in a Home in Gallipolis, OH
After years of noticing water seeping into their basement during heavy rains, homeowners in Gallipolis, OH, were motivated to address this problem once and for all. Hoping to permanently and cost effectively solve this issue, they contacted Ohio Basement Authority. We installed various waterproofing products to keep their basement dry. These included the sub-floor BasementGutter drainage system, a SafeDri sump pump, and an exterior FreezeGuard attached to the sump pump discharge line. The homeowners now have peace of mind knowing their house will be a safe and dry living environment for many years to come.
Preventing a Crawl Space From Leaking in Gallipolis, OH
While they have lived in their house for several years, homeowners in Gallipolis, OH, recently noticed a lot of moisture around the crawl space perimeter. The owners wanted to prevent this issue from becoming a bigger problem, like a flooded crawl space. As the owners researched potential repairs, they came across online information about Ohio Basement Authority. They were motivated to contact us and then meet with one of our inspectors to learn more about how we could help them. Our inspector then ventured into the crawl space to complete a thorough evaluation. He then discussed his findings with the owners, as well as their repair goals, and then recommended some of our reliable crawl space repair solutions. One of our crews then waterproofed the crawl space with the CrawlDrain drainage system and a SafeDri Super sump pump. The crawl space also was encapsulated with CrawlSeal liner. This thick and durable liner completely isolates the crawl space from the earth to properly seal it. CrawlSeal also acts as a moisture and vapor barrier, and it helps insulate the crawl space. ExTremeBloc panels also were placed on the wall for further insulation. Additionally, a FreezeGuard was attached to the exterior sump pump discharge line, and the vents were concealed by exterior vent covers. The homeowners now have peace of mind knowing these trustworthy solutions have helped them create a safer and healthier crawl space and home.
Push Piers Stabilize Cracking, Unstable Crawl Space Walls in Gallipolis, OH

Homeowners in Gallipolis, OH, have lived in their house for 11 years, but it wasn’t until recently that they noticed exterior cracking in their foundation. The visible stair-step cracks seemed to be in the foundation walls in the crawl space underneath the home.

The owners also noticed the home was slightly settling, and they were concerned with its safety and structural integrity. These issues are common as homes age, but they can be dangerous and costly to repair. They may also affect the home’s value and its ability to be sold, which the owners were also considering.

They knew they needed expert assistance, so the owners researched various repair companies through online resources like Home Advisor. They contacted Ohio Basement Authority, and were eager for us to install a permanent foundation repair solution.

One of our expert crews installed six Push Piers underneath the cracking and settling foundation walls in the crawl space. These heavy-duty, galvanized steel piers permanently stabilize the problematic foundation walls. They also offer the best opportunity to lift the foundation back to level.

The owners were excited to have this reliable system installed so the home will be a stable living environment for many more years to come.

Repairing Cracked Crawl Space Foundation in Gallipolis, OH

A crawl space in Gallipolis, OH had cracks in its foundation walls, so the homeowners called Ohio Basement Authority for help.

We visited the home and determined it would be best to use steel push piers to fix the problem.

These push piers are driven deep into the soil to the bedrock or stabler soil layer below. They can be installed from the interior or exterior of the home, and in this case, they were installed inside the crawl space. They provide an opportunity to lift a home back toward its original position, and this often closes cracks and improves the operation of doors and windows that may have become "sticky" due to foundation failure.

Six steel push piers were installed in this Gallipolis crawl space, and have corrected the cracking the homeowners were experiencing. They are very satisfied the with results.

They wanted to find the best permanent solution, so they contacted Ohio Basement Authority after learning more about our company online. We then installed a total of 24 IntelliJacks in the vast crawl space. These heavy-duty, galvanized steel supports permanently stabilize the floor joists and can rise the floors back to level. The IntelliJacks also are adjustable, and are designed to stop settling. The homeowners have peace of mind knowing their house will be a safer and stable living environment for many years.

Waterproofing and Stabilizing a Home in Gallipolis, OH
She has lived in her house since it was built 44 years ago, but it wasn’t until the last year that a homeowner in Gallipolis, OH, noticed water leaking into the basement through cracks in one of the walls. This seemed to happen during periods of heavy rain, resulting in puddles on the floor. The homeowner was worried this could lead to further damage, so she wanted to address these problems once and for all. She was motivated to contact Ohio Basement Authority after learning more about our company through online resources like Home Advisor. After meeting with one of our trusted inspectors, she was eager for one of our expert crews to install the perfect permanent solutions. Not only were the wall cracks repaired, one of our many reliable foundation repair products was used to reinforce the problematic foundation wall. Several Carbon Fiber supports were placed on the wall to permanently stabilize it and prevent any further cracking or potential inward bowing. The basement was then waterproofed with the BasementGutter and SafeDri systems. If any water seeps into the basement, the sub-floor BasementGutter drainage system will intercept it and direct it to the powerful SafeDri sump pump. The SafeDri gives the basement added protection with its backup battery that ensures its operation even if the power goes out. An FreezeGuard was attached to the exterior sump pump discharge line, and this line was tied into new downspout conductor lines that were installed on the property. The homeowner can rest easier knowing that her forever home is protected by these reliable solutions.

The entire crawl space was also encapsulated in CrawlSeal liner, and vent covers were installed on the home's exterior to prevent outside air and pests from entering the crawl space. A FreezeGuard was attached to the exterior sump pump discharge line, and an Access Well was instilled as a safe and secure exterior crawl space access point.
