An uneven sidewalk is more than just an eyesore; it’s a significant safety concern. A raised or sunken concrete slab creates a trip hazard that can lead to falls, serious injuries, and potential legal liability for property owners. Ensuring your walkways are safe and level is a responsibility that shouldn’t be overlooked.
Uneven sidewalks are a common issue for homeowners and municipalities alike. From a small crack to a significantly raised edge, these hazards can make navigating the path difficult, especially for children, the elderly, or individuals using strollers and wheelchairs. Addressing these problems promptly and effectively is crucial for maintaining a safe environment for everyone.
This guide will explore the causes of sidewalk trip hazards, compare traditional repair methods with a modern solution, and explain why concrete lifting is often the best choice. We’ll provide the information you need to make an informed decision about repairing your concrete walkways, helping you restore safety and peace of mind.

Understanding Sidewalk Trip Hazards
Uneven sidewalks don’t just happen overnight. They are typically the result of underlying issues that cause the ground beneath the concrete to shift. Understanding these causes is the first step toward finding a lasting solution.
Common Causes of Uneven Sidewalks
- Tree Roots: As trees grow, their roots can expand underneath a sidewalk, pushing the concrete slabs upward and creating dangerous, uneven joints.
- Soil Erosion: Water runoff from rain or irrigation can wash away the soil supporting the concrete, causing slabs to sink and settle unevenly.
- Freeze-Thaw Cycles: In colder climates, moisture in the ground freezes and expands, lifting the concrete. When it thaws, the soil contracts, and the slab can settle back down, but often not to its original position. This repeated cycle leads to progressively worse trip hazards.
- Poor Compaction: If the soil beneath the sidewalk was not properly compacted during construction, it can settle over time, leading to sunken concrete slabs.
The dangers associated with these hazards are real. A simple trip can result in sprains, fractures, or more severe injuries. For property owners, this translates to a significant liability risk. Many municipalities have ordinances that hold property owners responsible for maintaining the sidewalks adjacent to their land. Failing to address a known trip hazard could lead to costly lawsuits if someone is injured.
Traditional Sidewalk Repair Methods and Their Flaws
For years, property owners have relied on a few common methods to deal with uneven sidewalks. While these approaches can offer a temporary fix, they often come with significant drawbacks.
Concrete Grinding
This method involves grinding down the higher side of a concrete joint to create a sloped transition. While it can eliminate the immediate trip hazard, grinding creates an unsightly, uneven appearance and weakens the concrete slab, making it more susceptible to future cracking and damage. It doesn’t address the root cause of the problem, which is the unstable soil beneath.
Patching
Applying a patch of new concrete or asphalt over the uneven joint is another temporary fix. These patches often crack, crumble, and separate from the original concrete over time, especially in areas with freeze-thaw cycles. The result is an ugly, short-lived repair that will need to be redone.
Complete Replacement
Tearing out the old concrete and pouring a new slab is the most drastic and expensive option. This process is highly disruptive, often taking days to complete and damaging surrounding landscaping. It also generates a significant amount of waste, making it the least environmentally friendly choice.
Sidewalk Raising: A Superior Solution
A modern, efficient, and long-lasting alternative to traditional methods is concrete lifting, also known as sidewalk raising or poly-leveling. This innovative technique addresses the root cause of the problem by stabilizing the soil beneath the concrete slab.
The process is straightforward and minimally invasive:
- Drilling: Small, dime-sized holes are strategically drilled through the sunken concrete slab.
- Injection: A high-density, structural polyurethane foam is injected through the holes. This expanding foam fills the voids in the soil underneath the slab.
- Lifting: As the foam expands, it gently and precisely lifts the concrete slab back to its original, level position.
- Finishing: Once the slab is level, the small holes are sealed with a cement grout, making them nearly invisible.
The entire process is typically completed in just a few hours, and the sidewalk is ready for foot traffic almost immediately.

Key Benefits of Concrete Lifting
Concrete lifting offers numerous advantages over traditional repair methods, making it the preferred choice for fixing sidewalk trip hazards.
- Cost-Effective: Concrete lifting typically costs about half as much as a full concrete replacement, offering significant savings.
- Minimal Disruption: The process is quick and clean. There’s no need for heavy machinery or extensive excavation, which means your lawn and landscaping remain intact.
- Fast and Convenient: Most sidewalk leveling projects are completed in a few hours, not days. You can walk on the repaired sidewalk on the same day.
- Long-Lasting Results: By filling voids and stabilizing the soil, concrete lifting provides a durable solution that prevents the problem from recurring. The polyurethane foam is waterproof, so it won’t wash away or break down over time.
- Environmentally Friendly: This method uses less material and generates far less waste than concrete replacement. The polyurethane foam is inert and won’t leach chemicals into the soil.
- Aesthetically Pleasing: Concrete lifting preserves the original appearance of your sidewalk, avoiding the mismatched colors and textures that come with patching or grinding.
Choosing the Right Concrete Lifting Provider
While concrete lifting is a superior method, the quality of the work depends on the skill of the provider. When selecting a contractor, consider the following:
- Experience: Look for a company with a proven track record in concrete lifting services. Ask for references and look at before-and-after photos of their work.
- Equipment and Materials: Ensure the provider uses high-quality, professional-grade equipment and structural polyurethane foam designed for lifting.
- Training and Insurance: The technicians should be properly trained and certified. The company should also be fully insured to protect you from any liability.
- Local Regulations: A reputable provider will be knowledgeable about local municipal codes and any permit requirements for sidewalk repairs in your area.
