Job Stories From Bellville, OH
Foundation Stabilization and Basement Waterproofing in Bellville, OH

During the two years that they have lived in their house, homeowners in Bellville, OH, noticed two of the foundation walls were cracks and tilting inward in some spots. They plan to live in the house for many years, so they wanted to address these issues right away.

After hearing about Ohio Basement Authority, the owners were eager to contact us to learn more about how we could help them. They met with one of our inspectors who completed a thorough evaluation of the walls. Our inspector also pointed out areas with visible water intrusion. Our inspector then presented the owners with some of our reliable basement waterproofing and foundation repair solutions.

One of our crews then stabilized the foundation walls with PowerBrace beams and Carbon Fiber supports. Both of these solutions permanently reinforce the walls, and the PowerBrace beams offer the best chance to straighten the walls.

The basement also was waterproofed with the WaterGuard drainage system and UltraSump sump pump, as well as an exterior IceGuard attachment. All of these pieces work together to intercept seeping water and rid it from the home.

The owners are pleased to now have a safe, stable and dry basement because of these trustworthy repairs.

Crawl Space Encapsulation in Bellville, OH

After learning about Ohio Basement Authority, the owners were eager to contact us for further guidance. One of our inspectors completed a thorough evaluation of the crawl spaces, and he recommended the perfect repair solution.

One of our crews encapsulated the crawl spaces in CleanSpace liner. This thick and durable liner completely seals the crawl spaces to isolate them from the earth. CleanSpace also acts as a moisture and vapor barrier, and it helps insulate the crawl spacs.

The homeowners now have peace of mind knowing this reliable repair project has helped them create a safer and healthier living environment that they will be able to enjoy for many years to come.

I have a 5.5 x 9.5 foot concrete front porch slab that has dropped approximately 4 to 5 inches in the back. I think the poly leveling would be a good fix because the slab is still in good shape if it could be raised.
