About Reef Balls

Eternal Reefs is part of the Reef Ball family of companies. The Reef Ball Foundation and Reef Innovations are strategic partners to Eternal Reefs.

Reef Balls are the designed materials that Eternal Reefs uses for memorialization. Over the years, Reef Balls have established themselves as the world’s gold standard for artificial reef development and restoration. Collectively, the Reef Ball family of companies is the best, most experienced reef builders in the world.

Reef Innovations works with the Reef Ball Foundation worldwide, establishing new habitat for fish and other sea life. The entire Reef Ball family of companies is committed to preserving, protecting and enhancing the marine environment for future generations.

Reef Balls are the only designed reef materials that from the beginning were designed to replicate the natural substrata that Mother Nature uses for her reef development. Used in more than 70 countries, on more than 4,000 projects for a wide variety of purposes, there are more than 700,000 Reef Balls in the oceans around the world.

Brilliantly designed, the round, hollow and vented form leaves little space for storm energy to build up and move Reef Balls. With more than 80 percent of the weight of the Reef Ball in the lower quarter of the reef, they are extremely stable in the marine environment. We will never say that Mother Nature can’t do something, but if Reef Balls are moved there is going to be much more serious damage on shore.

A specialized concrete formula brings the pH content of the Reef Ball close to neutral. With the neutral pH content and a textured outer surface, the Reef Ball is the perfect medium to allow the micro-organisms [those little buds of life floating in the currents looking for a home] a place to land, burrow in, and mature and start to propagate before predators can feed on them.

Fish will migrate onto the Reef Balls as soon as they are placed. Depending on water conditions, we can see growth on these reefs in as little as a few weeks. Once these Reef Balls have matured, they are permanent additions to the marine environment. They will continue to develop and support marine life forever.

Reef Balls are well designed, well tested and are used throughout the world for designed reef development. Simply, they do what they are supposed to do and they stay where they are supposed to stay.
