If when laying paths, whether it's cobblestones, or with field stones, we do not use curbs, a layer of lean concrete can prevent them from sliding apart, framing the outer ankles. After paving, we cover it with earth. We go on foot along the paths made in this way. All roads and driveways, vehicles will travel on require concrete curbs. In them, too, paving stones are laid on a layer of lean concrete.
