Biorock technology uses a low voltage electrical current to stimulate the growth of minerals on submerged structures. This creates a limestone-like material similar to that found in natural coral reefs.

Biorock structures can provide a stable substrate for coral polyps to attach and grow, accelerating the restoration of degraded coral reefs.

While Biorock can be used for other purposes, like creating artificial reefs for mariculture (fish farming) or promoting the growth of seacrete building materials, its application in coral reef restoration is a major area of interest.
