Reef Ball Technology

What is a Reef Ball?

Reef Balls are patented structures engineered to withstand current and wave action, facilitate new coral growth, and house an array of marine life.

The concrete used in their construction is specially formulated to have the same PH as sea water and is texturized to ensure coral polyps have an ideal landing pad for propagation. Reef Balls are constructed without metal rebar so they do not collapse when the metal disintegrates over time.

The hollow inverted dome shape and holes serve several purposes. First, this design allows currents to pass through and around the ball, keeping it from tumbling around the ocean floor. Depending on ocean conditions, different types of anchors are sometimes used. Second, the hollow and open nature of the ball allows marine life to take shelter, which is essential for maintaining fish populations in coral colonies. For us, these holes additionally serve as a vault for cremains to be encased for eternity.

This intuitive design allows for the natural growth of new corals and will be supplemented by polyps harvested from coral nurseries. We are working along side marine biologists and local scientists to study the progression of coral growth on our Reef Balls. We aim to provide not just a memorial, but a living specimen for marine biologists to use in their quest to remedy our global climate crisis.

An Alternative to Traditional Burial

More and more people choose cremation every year, resulting in nearly 50% of all deaths ending in cremation today. This is owed to the decreased stigma surrounding cremation, the global movement towards more eco-friendly practices, and the ever-rising costs of making funeral arrangements. While traditional funerals provide an undeniable source of comfort and peace of mind to the many experiencing loss, we believe that even greater peace of mind can be attained through allowing our physical bodies to participate in the cyclical nature of death and ultimately new life.

Why Reef Balls?

Our World’s coral reefs are dying.

Rising ocean temperatures have caused the most catastrophic mass bleaching event in recorded history, with the most severe as recent as 2016.

This threatens biodiversity itself which lives in and thrives off of world reefs.

If no action is made, fish stocks will be lost and coastal protection from tidal events will be reduced dramatically. Countless small and large communities rely on these reefs to provide food for subsistence and economic growth.

Memorial Reefs International is dedicated to providing a service that works to mitigate this tremendous loss.
