Reef Ballstm are made by pouring concrete into a fiberglass mold (shown above) containing a central Polyform
buoy surrounded by various sized inflatable balls to make holes. Six mold sizes are available. Molds can be leased,
bought or one can simply pay a per use fee. Any type of concrete can generally be used, including end-of-day waste,
but additives are needed to give the Reef Ballstm high strength and to make the concrete suitable for
marine life growth.
The Reef Ball Group provides clients with concrete specifications and can supply the additives at special discounts.
Building an artificial reef usually requires artificial reef permits or access to use a permitted area. The Reef Ball
Group can help clients get or secure permission to use a permit. A training manual on how to use the molds and how to
deploy the modules is also included with the mold systems. Authorized Reef Ball contractors can provide additional
on-site training to make sure your project goes smoothly. Special programs are available to subsidize university
research projects and other worthy projects through the Reef Ball Foundation. Reef Ball Foundation also encourages
participation in projects by private organizations and has several sponsorship packages available for
companies that want to help the environment while gaining excellent press exposure.
The Group was formed to help folks build quality artificial reefs.
