Adding sand to paver patio
I recently put in a paver patio following the most common instructions. Dug the hole, added 6 inches of jagged gravel, tamped the gravel level, added 1 inch of sand, and laid the pavers. I then poured sand on top of the patio, and used a coarse broom to push the sand into the cracks while spraying it with water. I also hammered in a plastic border.
Since I have been done, it has rained almost every day. Whenever it rains, the sand in the cracks is washed out. Each time I have added and swept new sand into the cracks. The pavers have shifted slightly, but nothing too much(I used 16x16 inch pavers). Is this common with a new patio and will the sand/ground eventually settle so I can stop adding new sand? If so, how long should I expect to keep adding sand? Or is this a sign of an eventual problem that I need to fix?
