Once the sand base is prepared and leveled, carefully place the paver onto the sand bed. Center it within the excavated area. Use a rubber mallet to gently tap the paver across its surface, working from the center outwards. This action helps to settle the paver firmly into the sand, creating a stable and even surface. Avoid hitting the paver too hard, as this can cause it to sink too much or crack. Check the level again if necessary after setting.
