Traditional Dry-Stack Stone Walls:
Stone masonry originated with dry-stacked stonework where the walls are carefully Free-standing dry-stack stone walls are usually made larger at the base and then taper in slowly as the height increases.
For absolutely no expense but the labor, farmers built miles upon miles of stone fences this way.
Many old houses were built in a similar way. Where “mortar” was used, it was often merely mud or limestone plasters with little strength. The mortar functioned as caulking to stop the flow of air, rather than as cement to bond the stones together. Short, dry-stacked stone walls are especially ideal for landscaping projects. Taller walls require more skill and time. For more details on dry-stack stone walls, be sure to check out Building Stone Walls and Stonework: Techniques and Projects.
