Compacting causes the stones to form a tight bond with the bedding layer, which reduces the chance of your pavers sinking again. Sweep joint sand into the joints between the pavers. Do this by pouring a pile of sand on your hardscape and sweep it over the stones until your joints can’t hold any more sand.

How far apart should pavers be?

The recommended space between the pavers is 3 mm (⅛”). I don’t expect you to measure the gap but just set them beside one another. You should stop every 4 feet and pull a string line along the laying face, with a screwdriver, adjust that face to the string line.

What if it rains on my paver base?

Rain can certainly be an interfering factor in the paver installation process, but not so much as to completely interrupt the execution. … It is best to postpone work until the rain stops and the material dries, but keep in mind that pavers can get hot, so a sweltering summer day may not be the best choice either.
