Our Services for You

Basement Waterproofing
Water leaking inside your basement, especially during or following heavy rain, is common. So are issues with efflorescence, mold, musty smells, and other damage.
However, these troubles are not safe or healthy for your home or family. You should not have to put up with these health hazards and structural threats.
Ohio Basement Authority will permanently safeguard your home with our trusted, customizable interior drainage, sump pumps, dehumidifiers, wall vapor barriers, and other basement waterproofing solutions. Installed together, these products work to actively collect and remove water and humidity from your home, creating a safe and dry environment.

Foundation Repair
Your house relies on its foundation to stay standing for years to come, but the foundation will start shifting and settling, or suffer from other damage if the underlying soil is unstable. You’ll notice telltale symptoms including cracking walls, uneven floors, bowing walls, and sticking windows and doors.
The damage will only get worse, more costly to repair, and more dangerous for your family the longer it goes unrepaired. That is why swiftly taking action at the first sign of trouble is crucial.
Ohio Basement Authority offers a variety of permanent foundation repair solutions that bypass unstable soil and put your home back on solid ground. These products include wall anchors, wall braces, carbon fiber wall straps, crawl space supports, helical piers, and push piers.

Crawl Space Encapsulation & Repair
Some homes in Columbus were built on a crawl space or a partial crawl space may be adjacent to a basement. This area is susceptible to damage from water and humidity, including mold growth, infestations, wood rot, and unpleasant odors.
Because of the stack effect, all these issues negatively impact your home and family, from the air you breathe inside your house to the floors you walk on.
Ohio Basement Authority can stop these issues in their tracks by sealing and conditioning your crawl space with trusted crawl space repair and encapsulation solutions. We’ll install drainage, sump pumps, dehumidifiers, vapor barriers, thermal insulation panels, and support posts.

Concrete Lifting
Your property’s concrete, like your driveway and sidewalk, can succumb to damage over time, even though concrete is a tough material. Because of unstable underlying soil, the concrete slabs crack, sink, become uneven, and result in tripping hazards and other problems.
Concrete lifting methods have come a long way, and Ohio Basement Authority offers a unique solution that will effectively restore your concrete’s safety and appearance. Our polyurethane foam injections are lightweight, yet durable and can be used to effectively lift many areas including your sidewalk, driveway, pool deck, and interior slab floors.

Basement Finishing
By turning a basement into a well-designed living area, such as a cozy family room, modern home office, or inviting guest suite, you can significantly expand your home’s usable square footage. Professional basement finishing can improve your home’s layout and versatility, accommodating your evolving needs and lifestyle.
Basement finishing also addresses common issues such as moisture and poor insulation, creating a more comfortable and healthier living environment. Columbus homeowners benefit from expert solutions that resolve these concerns, ensuring a dry, well-insulated space that enhances the overall energy efficiency of the home.

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
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
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.
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.
