Since 2004 Trawangan Dive has run a Biorock® Specialty course as well as gaining further knowledge and experience in reef survey techniques and coral gardening. Certain areas of shallow water corals around the Gili Islands have suffered damage by combinations of coral heatstroke, disease, land-based sewage, global sea level rising, over-fishing and direct physical damage. A revolutionary new technology called Biorock® can make this possible.

The Biorock® Process involves a submerged steel structure that applies a safe low-voltage electrical current. Small pieces of live broken coral are then strapped to the structure and have been shown to grow at 3-5 times the normal rate while coral survival under higher water temperatures and pollution increased by 16 to 50 times. The Gili Islands are the second largest Biorock® site in the world, currently home to 63 Biorock® structures and have hosted International Reef Restoration Training Workshops.
