Crown and Slope

 

A gravel driveway should not be perfectly flat.  Proper crown and slope are critical for moving water away from the driving surface.

 

Without proper shaping:

 

  • water sits on the surface
  • potholes develop
  • soft spots form
  • washouts become more likely
  • gravel migrates
  • rutting increases

 

Every property is different, which means every driveway requires a different approach depending on:

 

  • elevation
  • runoff patterns
  • surrounding terrain
  • existing drainage
  • traffic patterns
  • material condition

 

The goal is controlled water movement.
