Business-grade parking lots, driveways, and sidewalks are built to last as long as you pick a reputable commercial parking lot paving company. Concrete is durable, relatively cheap, and easy to install, making it the ideal material for your paving needs. Plus, occasional visits from said contractor to make yearly repairs goes a long way to providing a safe and beautiful entryway for your company.

That being said, small issues do develop over time. For instance, cracks and potholes show up as a result of inclement weather and heavy use. One issue you should consider as a business manager or maintenance worker is the sinking and heaving of concrete sidewalks.

What Is the Problem?

Concrete heaving occurs when certain tiles in your sidewalk sink lower than the rest of the road. It’s a surprisingly common issue that you’ve probably noticed before, especially in the Spring.

After a long winter of freezing and thawing rain and snow, these sinks develop, posing a dangerous tripping and falling hazard to your employees and customers in addition to being downright ugly.


Yes. Some injuries caused by ill-maintained pavement can cost up to $30,000 in legal fees and insurance premiums. You also risk losing ADA (Americans with Disabilities Act) compliance, which causes its own set of problems.

In contrast, concrete repairs only cost a fraction of that amount. Take the precautionary steps to avoid costly accidents later by contacting a commercial parking lot paving company.

What Are the Causes?

You can’t completely prevent concrete damage or sidewalk sinking. However, being aware of the causes can help you understand the nature of these defects and decide when to contact the commercial parking lot paving company for repairs.

  • Inclement weather and quickly changing temperatures
  • Poor soil foundation
  • Unstable concrete base
  • Moisture and seeping water
  • Soil erosion (often caused by seeping water)
  • Expanding clay below the concrete
  • Dry ground soil caused by uneven shading or tree roots

Water is ultimately the largest enemy against your sidewalk and driveway concrete. Some of the common entry points for water include:

  • Rain and snow
  • Natural groundwater
  • Poor surface drainage
  • Garden water
  • Pipe leakages
