What is Concrete Leveling?
Concrete leveling is a cutting-edge method for restoring cracked, sunken, or heaving concrete slabs and sidewalks that doesn’t require tearing out and replacing the concrete. Uneven and cracked concrete surfaces can become tripping hazards and lower the overall curb appeal and value of your property. At American Foundation & Waterproofing, our Old North Knoxville concrete leveling and lifting experts specialize in the PolyLevel® system, a modern approach to concrete repair that raises, levels, and stabilizes slabs such as driveways, patios, pool decks, sidewalks, slab foundations, and garage floors. Unlike traditional concrete replacement methods, this solution provides fast, cost-effective, and durable results that restore function and appearance.
Should I Repair or Replace My Concrete?
Concrete is an extremely durable material, and it even gets stronger as it ages, so repairing it is often the best choice when surface flaws appear. Concrete lifting and leveling can save property owners time and money while avoiding unnecessary large-scale replacements.
For serious damage, such as large broken pieces or deep structural cracks, replacing the slab might be unavoidable. But if your property shows signs of sinking or uneven concrete, whether for a driveway or a slab foundation, PolyLevel offers Old North Knoxville homeowners a cost-effective repair solution. This method not only improves safety but also restores the value and appeal of your property.
Our Concrete Leveling Process
When uneven sidewalks or sinking slab foundations become a problem, homeowners turn to our experts for reliable concrete lifting and leveling services in Old North Knoxville. Our PolyLevel method ensures fast, accurate results that stand the test of time, and the entire process can be completed in less than a day. Here’s how it works:
Step 1: Drilling Injection Holes
Our Old North Knoxville concrete lifting process starts with drilling small, precise holes in the sunken slab to allow us to inject the polyurethane foam, which expands beneath the concrete, lifting it back to a stable, level position. This approach is fast, effective, and minimally invasive to the surrounding area.
Step 2: Insert Ports
Next, specialized injection ports are placed into the drilled holes. These ports connect to our equipment and serve as the entry point for the polyurethane foam.
Step 3: Inject PolyLevel®
Once ports are in place, an advanced polyurethane foam designed specifically for slab lifting is injected. As it expands, the foam fills voids under the slab and provides long-lasting stability without adding excess weight to the soil.
Step 4: Remove Ports and Patch Holes
After just 15 minutes, the foam hardens to create a durable base that can handle vehicles and heavy loads. We then remove the ports and seal the holes with concrete, leaving behind a smooth, even surface.
