Sidewalks are an essential part of any community infrastructure. They provide a safe and accessible path for pedestrians, young and old, to get around. However, concrete sidewalk repair, like any other paved surface, are susceptible to wear and tear over time. This can be caused by a variety of factors, including:  

• Environmental factors: Freeze-thaw cycles, exposure to sun and rain, and tree root growth can all contribute to the deterioration of concrete sidewalks.
• Heavy foot traffic: Areas with high pedestrian traffic, such as around schools, bus stops, and shopping centers, are more likely to experience sidewalk repair damage.
• Improper installation: If sidewalks are not installed correctly in the first place, they are more likely to crack and crumble prematurely.  

Uneven, cracked, or broken sidewalks can pose a serious safety hazard. They can cause trip and fall accidents, especially for people with mobility impairments. Additionally, damaged sidewalks can detract from the appearance of a neighborhood and make it less inviting for pedestrians.  

When to Repair Your Concrete Sidewalk

There are a number of signs that indicate that your concrete sidewalk is in need of repair. These include:

• Cracks: Hairline cracks are a common occurrence in concrete sidewalks, but they may not necessarily require immediate repair. However, larger cracks (wider than ¼ inch) or cracks that are accompanied by movement or sinking should be addressed promptly.
• Uneven slabs: Over time, concrete slabs can settle unevenly, creating a tripping hazard. If a sidewalk slab is uneven by more than ½ inch, it is time for repair.  
• Spalling: Spalling is when the surface of the concrete starts to flake or chip away. This can be caused by a number of factors, including freeze-thaw cycles, deicing salts, and improper curing.  
• Exposed rebar: If the steel rebar that reinforces the concrete becomes exposed, it is a sign that the concrete has deteriorated significantly and needs to be repaired as soon as possible.
