Job Stories From De Graff, OH
Keeping a Leaking Bank Basement Dry in De Graff, OH

As the managers of a bank in the Village of De Graff, OH, they wanted to make sure employees and customers would have a safe and healthy business environment. The basement of the building is used for storage, and the managers recently noticed evidence of water intrusion and damage.

The managers started to research how to address these problems, and they came across Ohio Basement Authority’s website. They were eager to contact us to meet with one of our inspectors and learn more about how we could help them. After evaluating the condition of the basement, our inspector recommended some of our reliable basement waterproofing solutions. One of our crews then installed the WaterGuard interior drainage system, replaced the older sump pumps with the UltraSump Battery Backup System, and installed a SaniDry dehumidifier.

Any seeping water from the walls and floor will be intercepted by the WaterGuard system and directed to the UltraSump sump pumps. Each system features two powerful pumps inside the liner, as well as an external backup battery that ensures the systems will always operate to pump water out of the basement. The SaniDry dehumidifier will clean and filter the air, control moisture and humidity, and prevent odors and potential mold growth.

The managers are pleased these trustworthy solutions were installed to keep the property dry and healthy for many years to come.
