Rock Armour works by absorbing and deflecting the impact of waves before they reach the beach or defended structure. The mass of the material absorbs the impact energy of storm waves, whilst the permeability (gaps between the rocks) slows the flow of water, reducing the erosion effect around structures or on the coastline.
