We Treat Your Home Like Our Own

Acculevel was founded in 1996, and is well known in the industry for repairing foundations, basements, and crawl spaces. We raise and repair concrete structures for thousands of customers per year.


A concrete slab sinks as the soil underneath it shifts. Often, the cause for this is erosion. Rain comes down and saturates the ground, mixing the water into the soil. Then, when the water drains away, it takes part of the soil with it. This erosion can happen gradually as a natural process, or suddenly if it’s caused by a broken pipe or ruptured drain. If the ground under a slab is eroding quickly or seems loose, you should evaluate your home’s guttering and plumbing systems. It’s possible the downspouts or plumbing are draining under the slab and washing out the soil.
In other circumstances, the slab moves because of the ground itself. It’s possible that it wasn’t properly compacted before the concrete was poured. The extreme weather cycles in the Midwest contribute another factor. The ground floods in the spring, then dries out during a summer drought, which prompts erosion Then there’s the winter freeze-and-thaw pattern. The ground expands when it freezes, and contracts as it thaws. This fluctuation also contributes to shifts in the soil, which accelerates the settling process.
Concrete rarely settles evenly; usually one end will sink more significantly than the other. When this happens, the stress of the uneven support will sometimes crack the slab. At that point, you have high and low points on the concrete, and a crack or joint between slabs that will catch a pedestrian’s toe. These are trip hazards and a liability issue.
Sometimes, an uneven slab can also cause damage to your home. It may redirect rainwater towards your house, instead of away from it. This leads to water damage to your foundation, and possibly to leaks in your basement or crawl space. Over time this extra moisture can cause serious damage. Water permeating into your home can cause rotting in the structural wood flooring system (sill plate, floor joists, etc) and allow mold to flourish and grow.
Slab lifting is done by injection. Small holes are drilled through the concrete slab, and material is injected below it. This material fills the void underneath the concrete, and gradually the pressure of this filler being forced under the slab creates lift. The type of fill material varies; many companies use a concrete or limestone slurry referred to as “mud” and this process is generally called mudjacking. As the slurry hardens, it creates lift below the slab.
At Acculevel, we use a polyurethane foam. In our experience, slabjacking provides a better and more reliable repair; once the foam is injected, the chemical reaction promptly begins to expand, and it’s this foam that does the lifting. Since it’s more immediate than mudjacking, it allows for better control.
In this video, one of our knowledgeable experts explains why we choose to perform slabjacking:
Slabjacking uses specialized equipment, but it’s usually installed in a standard-sized service truck that can park in the driveway or street without issue. Slabjacking repair work rarely requires an Acculevel crew driving across your lawn, or disturbing your landscape; the slabjacking equipment has a 250 foot injection hose to maximize our reach to the repair section.
In fact, there is very little mess generated at a slabjacking job site. Generally, crews only need to clean up some dust generated from drilling through the concrete, and maybe trace amounts of foam from the injection site.
This is preferable to the messy process of replacing a slab. Concrete demolition often involves the use of a jack hammer, which is noisy and creates debris that adds to landfills. Re-pouring concrete requires building forms, a concrete truck, and the use of this equipment in close proximity to the work site. This results in a significant amount of trash and upheaval on your property. The new slab can also be visually jarring, as it won’t match the other existing sections in color or texture.
Slabjacking works with the existing concrete slab, so the costs are limited. They depend more on the size of the slab being lifted, and the amount of void under the slab. (The larger the gap, the more material is required.) The costs to replace concrete can be double the price of slabjacking. For more details on costs, please review our article on costs comparisons.

Recently completed a slabjacking project on a concrete front porch in zip code 40031. The porch had settled unevenly, requiring stabilization to restore its level surface. The team efficiently lifted and leveled the porch, enhancing the home's curb appeal and ensuring safety, for an approximate cost of $1,600.

We tackled a high-moisture crawlspace issue for Joshua in zip code 40014. The crawlspace, with at least 18 inches of clearance, was struggling with damp conditions. Our team deployed an effective waterproofing strategy, enhancing the structure's durability. The cost of the project was approximately $15,000, offering a reliable long-term solution.
Near Crestwood, KY
In zip code 40071, we handled a project focusing on a sinking porch and adjacent walkway. The concrete slabs were dipping, presenting potential safety hazards. Our team applied slabjacking techniques to elevate and stabilize the area, ensuring a level and secure entryway for Sean. The overall cost for this repair was around $5,400.
Near Taylorsville, KY
Addressed significant leakage issues in Jon's basement, primarily around the sliding door and the junction where the foundation meets the floor. Our team implemented waterproofing solutions to prevent further water ingress, potentially stopping mold growth underneath the home. This comprehensive service was carried out in the 40223 area for an approximate cost of $3,000.
Near Louisville, KY
Handled foundation repair for Carissa in zip code 40068, addressing visible cracks in the cinder block structure. The crawl space was inspected to ensure overall stability and safety of the home. The job was completed for an approximate price of $4,275.
Near Smithfield, KY
Addressed crawlspace moisture issues at Andrew's property in zip code 40165. The project focused on waterproofing the crawlspace and managing insulation concerns, ensuring a dry and protected area beneath the home. This service was completed for an approximate cost of $3,200, providing much-needed moisture control.
Near Shepherdsville, KY
Visited Tina's property to address waterproofing needs within her crawlspace. Given her limited budget, our team focused on finding cost-effective solutions while maintaining quality. With a crawl entrance over 18 inches tall, we implemented measures to effectively prevent moisture intrusion. The project, completed for approximately $7,100, ensures the space remains dry and protected.
Near Mount Eden, KY
Recently, we completed a significant waterproofing project in Cindy's crawlspace area, located in the 40243 area. The goal was to address moisture issues and ensure long-term protection for her home. The crawlspace access was through the basement, and old insulation needed replacement due to deterioration. We installed a new system to prevent potential water intrusion effectively. The project's approximate cost was just over $9,000.
Near Louisville, KY
Installed a new sump pump for Chris in the 40299 area. This essential upgrade is designed to manage water effectively and prevent basement flooding, enhancing the home's foundational integrity. The service was completed with an investment of about $2,050.
