Right:  This simple driveway project is an example of the difference a skilled machine operator makes.  This project started where a common driveway splits into two separate driveways.  Both driveways were built up using sand/clay mix on site.  We completed the left driveway ensuring it was very smooth, slightly crowned, and well compacted.  The result is a very stable driveway which requires little maintenance.  The driveway on the right was completed by the homeowner and is very wavy, not compacted or crowned correctly.  The resultant driveway is a mess when it rains, and rides rough when dry.
