What is Concrete Leveling?
Property owners often deal with sinking concrete slabs, which not only detract from curb appeal, but can cause tripping hazards. Whether your driveway, sidewalk, porch, patio, or pool deck is uneven, settlement can often be resolved without a full slab replacement. Our Alcoa concrete leveling contractors lift and stabilize slabs using the PolyLevel® system, designed to support the soil below and bring concrete back to level. The result is an even surface, minimal disruption, and a more cost-effective solution compared to slab replacement.
Should I Repair or Replace My Concrete?
Concrete is very durable, which is exactly why repair is often the best option if conditions are correct. Concrete leveling addresses the underlying cause of many slab problems resulting from the loss of support beneath the concrete. Filling voids and raising settled slabs improves support, reduces future movement, and helps keep slabs aligned so cracks and offsets are less likely to continue. This lifting and leveling method also avoids the higher price tag, longer timeline, and larger disruption that come with concrete replacement.
Replacement can be necessary when damage is extensive, such as large missing sections or deep spalling. For many homeowners, our concrete lifting and leveling service in Alcoa delivers a budget-friendly improvement to safety and appearance, with less downtime and less mess than removing and repouring concrete.
Our Concrete Leveling Process
Sinking concrete is more than a cosmetic issue. It can trigger liability risk, create unsafe walking paths, and reduce property value. Homeowners and businesses turn to our concrete leveling contractors for PolyLevel® concrete lifting in Alcoa because it is fast, precise, and less expensive than full slab replacement. Most repairs are completed the same day. The steps below break down what to expect.
Step 1: Drilling Injection Holes
Small holes are drilled in targeted areas across the slab. These access points allow the polyurethane foam to be delivered beneath concrete slabs where gaps and weak spots have developed.
Step 2: Insert Ports
Low-profile ports are set into each drilled hole to lock the delivery lines in place. This setup supports accurate injection and consistent coverage under the slab.
Step 3: Inject PolyLevel®
PolyLevel® foam is injected into the voids beneath the concrete and expands to fill the open space. As the foam expands, the slab is lifted and stabilized with controlled precision. The lightweight material helps prevent additional stress on the soil while providing strong, reliable support.
Step 4: Remove Ports and Patch Holes
Ports are removed after leveling is complete, then each opening is patched with fresh concrete for a blended finish. PolyLevel® reaches service-ready strength in about 15 minutes, making it an efficient and cost-effective option for driveways, patios, walkways, and pool decks.

Frequently Asked Questions
Concrete leveling is a repair process that lifts and stabilizes sunken or uneven concrete surfaces. It’s often used on sidewalks, driveways, patios, garage floors, and other concrete slabs that have settled over time.
Our technicians drill small holes into the slab and inject expanding foam material underneath to fill voids and gently lift the concrete back into place. The holes are then sealed, leaving the surface smooth and even.
Most leveling projects can be completed in just a few hours. The material hardens quickly, allowing you to walk or drive on the surface shortly after the work is done.
Leveling is typically faster, less disruptive, and more cost-effective than replacing the entire slab. Replacement is usually only needed when the concrete is severely cracked or structurally damaged.
You may need leveling if you notice uneven slabs, cracks in your driveway or patio, gaps between the concrete and your home, a chimney that appears crooked or cracked, or exterior siding or bricks that are cracked or misaligned.
