Dry-stacked stone work has been used throughout the world for many centuries to build houses, walls, staircases and bridges. Many of them still stand, hundreds of years later. Dry stacked stonework is done without the use of mortar or glue to bind the rocks. Carefully selected stones are knitted together using a time-tested technique that forms an interlocking, load bearing structure that lasts for hundreds of years. In the event of an earthquake, properly built dry stacked stone becomes tighter and stronger than stone bound with mortar. Dry stacked stone allows for proper soil drainage, where as concrete structures do not. In addition, dry stacked stone structures house many types of living creatures from reptiles to butterflies, who like to find shelter at night in the cracks of the warmed stones. Unique and well-crafted stone structures bring combined beauty and durability to an ecologically designed garden
