Job Stories From Nevada, OH
Fixing and Protecting a Cracking, Settling Wall in Nevada, OH

As they moved into their house, new homeowners in Nevada, OH, noticed some glaring problems with one of their foundation walls. The wall was cracking and slightly tilting inward, and there were several areas of gaps between the concrete blocks. These are signs of foundation failure and settlement that the homeowners wanted to be sure to address right away.

They found information about Ohio Basement Authority online, and they were eager to contact us for further guidance. They met with one of our inspectors who assessed the condition of the wall and then recommended some of our reliable foundation repair solutions.

One of our crews then installed several Push Piers underneath the settling foundation wall by driving them deep into the soil. These heavy-duty, galvanized steel piers permanently stabilize the foundation wall and offer the best opportunity to lift it back to level.

Once it was obvious the wall had been leveled, Carbon Fiber supports also were placed on the wall to reinforce it in its current position. These durable supports, which firmly adhere to the wall, also prevent any further cracking or inward bowing.

The homeowners now have peace of mind knowing these trustworthy repairs have helped them create a safe and stable living environment that they will be able to enjoy for many years to come.

Waterproofing a Leaking Basement in Nevada, OH

After living in their house for several years, homeowners in Nevada, OH, noticed some issues in their basement. Water appeared to be leaking inside the basement, resulting in puddles on the floor and visible damage. The sump pump also appeared to be failing to keep up with this seeping water.

Hoping to find the best solution before any serious damage resulted, the homeowners started to research how to best address these problems. They contacted Ohio Basement Authority after learning about our company online, and they were eager to meet with one of our inspectors. The inspector evaluated the condition of the basement, and he then presented the owners with some of our reliable basement waterproofing solutions.

One of our crews then installed the WaterGuard interior drainage system and a TripleSafe sump pump. Any water that seeps inside the basement will be intercepted by the sub-floor WaterGuard system and directed to the TripleSafe. Along with three powerful pumps inside its liner, the TripleSafe also is equipped with an external backup battery to ensure its operation even during power outages. The TripleSafe then pumps the seeping water out of the basement and away from the home’s foundation.

The exterior sump pump discharge line was tied into a new downspout conductor line, and a LawnScape outlet was used to conceal the end of this line in the yard.

The homeowners are pleased these trustworthy solutions were installed to help them create a safe, dry and healthy living environment.

Encapsulating a Crawl Space for a Healthier Home in Nevada, OH

As a 200-year-old house in Nevada, OH, continued to be handed down through a family, the more recent familial homeowners wanted to do everything they could to protect the home’s health, safety and historical integrity.

While they rarely go into the crawl space, the owners wondered if this area under the house was impacting the rest of the living environment. They were motivated to address any concerns when they attended a popular home and garden show event. They spoke to some of Ohio Basement Authority’s staff and booked an appointment to meet with one of our inspectors.

The inspector visited the home to complete a thorough evaluation of the crawl space. He found a very unhealthy area full of failing insulation and plastic floor liner. He then recommended some of our reliable crawl space repair solutions.

One of our crews first began transforming the crawl space by carefully removing all the insulation and other nuisances. The crawl space was then encapsulated in CleanSpace liner. This thick and durable liner, which is similar to swimming pool liner, completely isolates the crawl space from the earth. It also acts as a moisture and vapor barrier, and it helps insulate the crawl space. Spray foam was applied to the band joists to further insulate the area.

The homeowners now have peace of mind knowing these trustworthy repairs have enhanced the health of the crawl space, as well as the rest of their home.
