We employ a unique method that allows coral reefs, and other marine ecosystems including seagrass, salt marsh, mangrove, and oyster reefs to survive and recover from damage caused by excessive nutrients, climate change, and physical destruction by greatly increasing the settlement, growth, survival, and resistance to stresses, including high temperature and pollution, of all marine organisms. As a result, Biorock™ electric reefs keep ecosystems alive when they would otherwise die from severe stress, and restore them at record rates where there has been no natural recovery. We grow back severely eroded beaches at record rates.

The Biorock™ method of coral reef restoration was originally developed in 1976 by the late architecture Professor Wolf Hilbertz to grow building materials in the sea. The Biorock™ electric reef method produces materials that are the only marine construction materials that grow, get stronger with age, and are self-repairing. He called it Mineral Accretion Technology™, Seacrete™, or Seament™.

In 1987 Tom Goreau invited Wolf to come to Jamaica to work with him to develop applications for Mineral Accretion Technology™ focusing on coral reef restoration. They decided to call their co-developed electric reef technique the Biorock™ method because it not only grew hard limestone rock for structural purposes but also greatly increased the growth of corals and marine organisms. Soon after they founded the Global Coral Reef Alliance to pursue research and development of Biorock™ electric reef methods using Mineral Accretion Technology™ for coral reef and marine habitat restoration.

Mineral Accretion Technology™ and Biorock™ electric reef restoration methods have been successfully applied to fish and shellfish mariculture as well as to growing limestone breakwaters to protect islands and coastal areas from erosion and rising sea levels. Around 500 Biorock™ electric coral reef restoration structures have been built in around 40 countries all around the world, mostly in small islands, with around 400 of them in Indonesia with our local partners, Biorock™ Indonesia.
