Searching for solutions for uneven sidewalks? If so, don’t hit that back button because you’re in the right place. Uneven sidewalks are more than just an eyesore; they pose serious safety risks and can lower property value. Whether a minor trip hazard or a significant slab misalignment, homeowners and property managers must decide between quick fixes and long-term solutions. While temporary DIY approaches might seem appealing, they often fail to address the root cause of the problem, leading to costly repairs.
If you’re dealing with an uneven sidewalk in the Atlanta metro area, it’s essential to understand your options. Let’s break down the differences between quick fixes and permanent solutions—and why professional concrete leveling with polyurethane foam injection is the best long-term investment.

Understanding Why Sidewalks Become Uneven
Before choosing a repair method, it’s essential to understand why sidewalks shift and sink in the first place. Some of the most common causes include:
- Soil Erosion – Water from rain, irrigation, or poor drainage can wash away the soil beneath your sidewalk, creating voids that cause sinking.
- Freeze-Thaw Cycles – In colder months, water seeps into cracks, freezes, and expands, forcing the concrete to shift. When it thaws, the slab settles unevenly.
- Tree Roots – Growing roots can push concrete slabs upward, creating an uneven walking surface. We’ve all seen examples of this.
- Poor Compaction – If the soil wasn’t adequately compacted before the concrete was poured, it may settle over time, leading to an unstable foundation.
- Heavy Loads – Excessive weight on a sidewalk (such as parked vehicles or construction materials) can accelerate settling.
Now that we understand the root causes, let’s explore the different repair approaches.
Quick Fixes for Uneven Sidewalks: Are They Worth It?
Many homeowners and property managers attempt quick, low-cost fixes for their uneven sidewalks, but these solutions often fail to provide lasting results. Here are some of the most common temporary repairs:
1. Grinding Down the Raised Edge
One of the quickest ways to reduce a tripping hazard is to grind down the raised portion of a sidewalk where one slab has lifted higher than another. While this method may smooth out the transition, it doesn’t address the underlying problem. Over time, the concrete will continue to shift, and grinding may need to be repeated frequently.
2. Filling Cracks with Caulk or Epoxy
Caulking or using epoxy to fill cracks might temporarily prevent further water intrusion, but it won’t stop the underlying cause of the settlement. Eventually, the slab may sink further, causing the crack to widen or new cracks to form nearby.
3. Laying Down Asphalt or Concrete Patching Material
Some homeowners attempt to level uneven sidewalks by layering asphalt or concrete patching material on the existing slabs. This may create a smoother surface temporarily, but it’s not a permanent fix. Patches can break down over time, especially in areas exposed to heavy foot traffic and weather fluctuations.
4. Raising the Slab with DIY Jacks
Some DIY enthusiasts attempt to lift their sinking concrete slabs with jacks. However, without the proper knowledge, this can lead to structural damage, further cracking, or even personal injury. Concrete is heavy, and attempting to lift it improperly can result in more harm than good.
Long-Term Solutions: The Right Way to Fix Uneven Sidewalks
If you’re looking for a permanent solution, consider professional concrete leveling techniques. At Signature Polyjacking, we specialize in polyurethane foam injection, the most effective and lasting method for lifting and stabilizing uneven sidewalks.
Polyurethane Foam Injection (Polyjacking) – The Best Solution
Polyjacking is a modern, cost-effective technique that uses expanding polyurethane foam to lift uneven sidewalks back to their original position or as close as possible. Here’s how it works:
- Small, dime-sized holes are drilled into the affected concrete slab.
- A two-part polyurethane foam is injected under the slab.
- The foam expands, filling voids and gently lifting the concrete back to level.
- The holes are patched, and the surface is ready for use within minutes.
Why Choose Polyjacking?
✅ Fast Results – Most sidewalk leveling projects using polyjacking are completed in a few hours.
✅ Minimal Disruption – No heavy equipment or loud demolition is required.
✅ Long-Lasting Stability – The water-resistant foam won’t wash away like mudjacking material.
✅ Cost-Effective – More affordable than full sidewalk replacement.
✅ Environmentally Friendly – Reduces waste by preserving existing concrete rather than replacing it.
Mudjacking – An Older Alternative
Mudjacking is another professional method used to level concrete, but it’s outdated compared to polyjacking. Instead of lightweight polyurethane foam, a slurry of cement, soil, and water is pumped under the slab. While it can lift sidewalks, mudjacking has several drawbacks:
❌ Heavy Material – The slurry adds weight to already unstable soil, leading to further settlement.
❌ Longer Cure Time – It can take hours or even days before the sidewalk is usable.
❌ Less Precision – Achieving a perfectly level surface is more challenging.
❌ Not Water-Resistant – The slurry can break down over time if exposed to moisture.
Full Concrete Replacement – When Is It Necessary?
Sometimes, removing and replacing a severely damaged sidewalk is the only option. Replacement might be the best long-term solution if the concrete is extensively cracked, crumbling, or has significant structural damage. However, this process is costly, time-consuming, and requires extensive labor and material.
Why Uneven Sidewalk Leveling Is Not a DIY Project
Many homeowners attempt DIY solutions to save money, but concrete leveling is not a do-it-yourself job. Here’s why:
- Specialized Equipment Is Required – Professional concrete lifting requires industrial-grade polyurethane injection equipment.
- Lack of Expertise Can Lead to Further Damage – Incorrect lifting techniques can cause additional cracking or slab breakage.
- Safety Concerns – Concrete is heavy, and improper handling can result in injury.
- Temporary Fixes Waste Money – DIY patches often need to be redone, making them more expensive in the long run.
For the best results, hiring a professional concrete leveling contractor like Signature Polyjacking is always wise.
