Gravel driveway construction begins with proper planning and preparation. You will need to grade and compact the base material very well, or you will not get good results. Once you have the grading done and the base material compacted, you can lay a thin layer of gravel. The layer depth depends on what size gravel you use. Smaller size gravel requires a thicker layer than large size gravel. After
. the gravel has been put down, you can run a vibrator to compact it well into the base material. If you have never done a gravel driveway, you would do well to consult with a paving professional.
