After pouring the drive, we came back to clean up here. Borders like these more than double the amount of work. Then there's the cobblestone walk and entry. Exposed pea gravel looks neat, but it's messy. We're taking about 50-70 years off the top by washing the sand away, and it often tends to effervesce. That's a splotchy drive due to the calcium leaching. This occurs from the water, or a rain, but not so bad on this job. So long as it's consistently exposed, the grays soon even out.
