- Dolosse are concrete structures used along the South African coast to prevent erosion of breakwaters, harbor walls, and coastal construction.
- They can weigh up to 80 tons, resist movement by rough seas, dissipate wave force by allowing water flow through and around them, and can be placed randomly or stacked neatly.
- The invention is South African, but the inventors received no payment or recognition and did not patent it due to their employment with the South African Railway & Harbour Services.
