Updated Exterior Drainage Will Help Keep a Basement Dry in Nashport, OH

After living in their house for one year, homeowners in Nashport, OH, started to notice a problem in the basement. There was visible evidence of water intrusion and damage in a few corners, which also happened to be in the same area as exterior gutter downspouts.

The owners wanted to avoid having to deal with flooding and similar damage, so they began to research potential repairs. After finding information online about Ohio Basement Authority, the owners were eager to contact us for further guidance. They met with one of our inspectors who completed a thorough evaluation of the home and its drainage. Our inspector then recommended updating the exterior drainage system.

One of our crews then replaced the lines with newer, thicker pipe used for the downspout conductor lines. These lines were placed in the ground and directed to drain water to a hillside the edge of the property.

The homeowners are pleased to now have an updated exterior drainage system that will help keep their home dry.

Stabilzing Cracking, Settling Walls in Nashport, OH

Since moving into their house almost 20 years ago, homeowners in Nashport, OH, have been keeping an eye on potential structural issues. Two of the walls in the home’s attached garage were cracking. One of these walls was in worse shape, as mortar was missing and daylight could be seen through the stair-step cracking patterns. The latter issues indicate foundation settlement.

Not only were the homeowners concerned with the stability of the garage, they were worried these problems could negatively impact their ability to sell the house in the near future. They began to research how to best address these issues, and they contacted Ohio Basement Authority after learning more about our company online. After meeting with one of our inspectors, the homeowners were eager for one of our crews to install our reliable foundation repair solutions.

These included several Carbon Fiber supports on the less severe wall. These heavy-duty supports permanently stabilize the foundation wall where they were installed, and they prevent any further cracking or inward bowing.

Several Helical Piers also were installed underneath the other wall. These durable galvanized steel piers were mechanically driven down to competent soil and attached to heavy-duty foundation brackets on the garage’s footing. These piers permanently stabilize the foundation, help prevent further settlement, and offer the best opportunity to lift the settling section back to level.

The homeowners now have peace of mind knowing these trustworthy repairs have helped them create a structurally sound home.

Hello - Radon levels have been running a little high in our home (6.0 pCi/L). It's a newer home that was built with a passive vent. Would just like to get an estimate on activating the current passive system. -- Thanks!

I have a concrete slab that has settled against a block wall. Water will pool in that area for days after it rains and becomes slippery. I would like to know if it's something that can be lifted or needs to be repoured. Thanks
