A dolos is a reinforced concrete block in a complex geometric shape weighing up to 80 tonnes, used in great numbers as a form of coastal management to build revetments for protection against the erosive force of waves from a body of water. The dolos was invented in 1963 by South African harbour draughtsman, Aubrey Kruger, and were first deployed in 1964 on the breakwater of East London, a South African port city.
