Our Services for You

Basement Waterproofing
Due to its below-ground location and our area’s wet weather, your basement and anything in it can easily be damaged. Look for flooding and water damage, mold and mildew, efflorescence, and unpleasant odors.
While these problems are common, they negatively impact your home’s structural integrity and your family’s health and safety.
Ohio Basement Authority will get to the root of these problems and permanently address them with quality solutions that actively collect and remove water and humidity. These customizable products include interior drainage, sump pumps, dehumidifiers, wall vapor barriers, and more.

Foundation Repair
Your home needs a sturdy foundation for safety and longevity, but that foundation is easily damaged by unstable, expansive soil. Typical symptoms include cracks, bowing walls, uneven floors, drywall cracks and nail pops, and more.
Left to fester, these problems threaten your home’s stability. They also result in cosmetic issues, expensive repairs, and safety hazards for your family.
Our team uses only the most trusted and durable solutions to permanently stabilize your home and put it back on solid ground. These include various wall repair and reinforcement systems, pier systems, and crawl space supports, all of which are fully customizable to meet your foundation’s unique needs.

Crawl Space Encapsulation & Repair
Instead of a basement, some homes in Cincinnati are built on top of a crawl space. These hollow areas are just as prone to damage such as elevated humidity, infestations, mold, musty odors, and rotting wood.
These are more than just minor nuisances. They can aggravate your family’s existing health issues, damage your home’s structure, and create an overall unsafe environment.
The best way to tackle these problems is to seal and condition the crawl space. Ohio Basement Authority accomplishes this with permanent crawl space repair and encapsulation solutions including drainage, sump pumps, thermal insulation, vapor barriers, dehumidifiers, and support posts.

Concrete Lifting
Concrete is widely used for its durability, but areas such as your sidewalk and driveway can sustain various damage. If the soil under the concrete is not stable, the concrete slabs crack and sink, resulting in uneven areas, tripping hazards, and other problems.
There are many concrete lifting and repair methods on the market today, and our team at Ohio Basement Authority provides safe, fast, and effective concrete lifting with innovative polyurethane foam injections. This lightweight, yet durable foam is less invasive, quick-curing, eco-friendly, and can be applied to many surfaces such as your sidewalk, driveway, pool deck, and interior slab floors.

FAQ
Many homeowners believe that moisture simply comes with the territory of owning a house with a basement. While dampness is common, it is not a normal or safe condition for your basement or home.
Below are some of the typical ways moisture enters your basement. If you notice any of them, reach out to your local basement waterproofing professionals right away for an inspection and repairs.
- Cracking and leaking walls and floors
- Leaking windows and window wells
- Plumbing leaks
- Appliance leaks
- Faulty sump pump
If your home has shifted and settled due to unstable soil, Ohio Basement Authority will install a pier system beneath your foundation to permanently stabilize and help lift it.
Steel helical piers or push piers are placed deep into the soil, bypassing problematic surface soils. They are advanced far enough until they hit bedrock or more stable load-bearing strata that won’t be affected by the elements.
Helical piers have screw-like blades on the ends of each pier, making it easier for them to “bite into” the soil. They are ideal to use on lighter structures.
Push piers, also known as resistance piers, offer the same support. They are manually pushed into the ground and work best with heavier buildings.
Crawl space encapsulation involves several precise steps that are best left to trained professionals. Your crawl space can be both delicate and dangerous, so trust the pros to take care of inspecting and repairing this area.
Every home is different, but here are the steps experts, like our team at Ohio Basement Authority, take to encapsulate crawl spaces:
- Remove any debris, failing insulation, and standing water
- Dig interior perimeter trench and place interior drainage inside
- Install a sump pump and connect it to the drainage
- Seal vents and place thermal insulation on walls
- Install crawl space supports under floor joists
- Cover crawl space walls and floor with a vapor barrier
- Add an energy-efficient dehumidifier
There are many methods available for concrete lifting and repair, but polyurethane foam injections stand out as the superior option.
After the two-part foam is mixed by installation professionals, it is injected underneath affected slabs through small holes that were drilled in the concrete. The foam expands to fill voids between the slabs and underlying soil. While doing so, it precisely lifts the concrete as close to its original position as possible.
The lightweight, yet durable foam cures quickly (in just 15 minutes). It is eco-friendly, will not wash out, and offers effective, long-lasting protection for your concrete and the soil below.
