The Reef Ball Foundation is a 501(c) 3 publicly supported non-profit and international environmental NGO.

Reef Ball Commercial is a division of the nonprofit organization that sells Reef Ball molds, provides consulting and design assistance for designed artificial reef projects, licenses uses of Reef Ball molds and technologies, and manages Reef Ball Authorized Contractor and reseller programs to create revenues to sustain the mission statement of Reef Ball Foundation.

Our mission is to rehabilitate our world's ocean reef ecosystems and to protect our natural reef systems using Reef Ball artificial reef technologies. Reef Balls are artificial reef modules placed in the ocean to form reef habitat.

What's A Reef Ball ™

Reef Balls are the world's leading designed artificial reef modules. They are simply the safest and most effective way to create sustainable marine reef habitat. With over 10 different sizes and 20+ styles, they have been tailored to meet nearly any artificial reef project's goals and they will achieve this in a safe, long term, environmental way. Designing an artificial reef yourself....or relying on unproven techniques will waste your time and money and failed designs could Diagram of Reef Ball Mold Systemharm the same marine life you are trying to enhance. Reef Balls are easily made from an ingenious, easy to use, portable fiberglass mold system that can be supplied anywhere in the world. We've even got matching grant programs to keep the cost of molds and training as low as possible. The more you learn about Reef Balls, the more you will find that the best solution for your project is custom designed artificial reefs that take into account your specific project goals.

Marine Friendly Concrete

https://www.reefball.org/brochure.htm#:~:text=Marine%20Friendly%20Concrete,pH%20as%20high%20as%2012.

The concrete used to make Reef Balls features W.R. Grace's Force 10,000 micro silica to create a super high strength, abrasion resistant, concrete that has a pH similar to natural sea water. This is unlike regular concrete which has a surface pH as high as 12. This high pH (the sea has a natural pH of 8.3) can inhibit the settlement and growth of many species of marine life including some larval corals. Micro silica gives Reef Balls an expected life of 500 or more years.

Other admixrtures include a high range water reducer, and microfibers. Reef Balls are made without using any iron rebar that would cause cement to eventually degrade in sea water.

Reef Ball encourages all mold users to develop relationships with researchers and to conduct monitoring or other types of studies. It is our goal to assist science to learn as much about artificial reefs and their use as a management tool so that our projects and other artificial reef projects have a better chance of reaching the intended project goals. Although non-Reef Ball specific artificial reef papers are too large to post on the Web, most researchers will gladly share their research so an effort is being made to offer e-mail links to major researchers.  We ask that researchers submit all Reef Ball specific studies for inclusion on this site.

Over 500,000 Reef Balls have been deployed worldwide in over 3,200 projects. All Reef Ball Foundation projects require monitoring and most include scientific investigation. Overwhelmingly, the evidence is quite clear that Reef Balls create essential fish, invertebrate and marine plant habitats. In most cases, the evidence indicates that Reef Balls can easily reach the 80% or more of the natural species diversity and population densities of nearby natural reef systems within just a few years, however achieving the ultimate goal of 100% may take five or more years and will nearly always require special treatments to match local conditions. Some major treatments being studied and always in need of local studies include:

-Use of various size mixes of Reef Balls
(i.e. ratio of small to medium to larger sized Reef Balls)

-Spacing and layout of the Reef Balls

-Addition of internal structure to create juvenile preferred habits

-Hole sizing and placement including surface texturing, bottom shape features, etc.

Although concrete typically begins its life at a highly basic pH of about 13, the pH values at exposed surfaces soon fall as reactions occur between carbon dioxide from the atmosphere and alkalis in the concrete—a process known as carbonation. Over time, fronts of
carbonated concrete, with pH values of about 8.5, advance below exposed surfaces.

It may be necessary to determine the depth of this front, as carbonated concrete can allow corrosion of reinforcing steel. This can be done by spraying a phenolphthalein indicator solution onto a fractured or cut surface of the concrete and noting the location of a color change. In this case, the color change occurs when the solution contacts a material with a pH of 9 to 9.5. The depth of the carbonation
front can also be evaluated by using a drill to collect samples at selected depths. In this case, the pH of the powdered samples can be evaluated using the standard test methods described in the following sections.

It may also be necessary to evaluate the pH of a concrete floor surface, as the adhesives used to install vinyl flooring or carpet tiles can be damaged when applied to substrates with pH values exceeding 9 (many flooring manufacturers won’t issue a warranty on their
installed products unless the pH has been verified to be within acceptable ranges). Although paragraph 5.3 in ASTM F 710-05, “Standard Practice for Preparing Concrete Floors to Receive Resilient Flooring,”1  indicates a procedure
to be used to test concrete floors for alkalinity, we
believe the procedure isn’t adequate. We therefore
propose an alternate standard procedure for testing the
pH of concrete.

I would also like to know if the local cement producers marine grade cement with lower pH levels. I can try to get in touch with the production engineers at bacnotan (Holcim cement).

Malaysia has been working with Reef Balls for a long time. Note an article from 2006

Malaysia: 200 reef balls 'planted' to restore corals

https://www.artificialreefs.org/Articles/malaysia%20200%20reef%20balls%20'planted'%20to%20restore%20corals%20%20reefblogger.htm

About 200 reef balls weighing a total of 540 tonnes were planted at the Mid Reef area off Manukan Island, near here, to restore coral reefs wrecked by the Greg Storm about eight years ago, Thursday.

As for Sabah Parks, it is the first time that reef balls were used towards the conservation of marine lives in Tunku Abdul Rahman Parks and Karim said the next area identified was Selingan Island, Sandakan under the Ninth Malaysia Plan.

The reef balls that cost Sabah Parks about RM398,000 are sourced from Dasanrama Enterprise.

< Edited >

At the same time, he hoped Sabah Parks would monitor the reef balls so that it would not be damaged by fish-bombing.

"It would be a waste of money if it is bombed and we have to replace it again and again," he said.

Despite the widespread news on the degradation of marine resources among urban centers, the City Environment and Natural Resources Office is riding on the waves of change to champion marine biodiversity that benefits the whole community. Through the groundbreaking initiative dubbed as the Integrated Management and Sustainable Environmental Approach to Coastal and Underwater Resources (I’m SEACURe), the nominees were able to achieve a widespread change. The office not only rehabilitated the marine environment of Tagum but also improved the economic status of the 4,800 households that largely depend on the sea for a living.
I’m SEACURe aims to conserve marine wildlife and resources, and at the same time alleviate poverty in coastal communities through inclusive and sustainable management of natural resources.
Since the passing of the city ordinance no. 249 in 2007, CENRO had accomplished the enhancement of artificial coral reef project, desiltation of waterways and rivers, installation of signages and mooring buoys, strong law enforcement, mangrove habitat restoration, empowerment of fisherfolks, improvement of facility and personnel, and registration and coding of fishing vessels.
These activities resulted to ecological impact such as improvement of the marine biodiversity condition of reef and economic impact such as increase in fishery production.
The Marine Protected Area of Tagum was recognized as well by SMARTSeas PH as one of the best performing locally-managed MPAs in Davao Gulf last Oct. 10, 2018. In addition, CENRO’s artificial coral reef project was also featured in the national broadsheet Business Mirror last March 26, 2017 highlighting the effort of rehabilitating coral reef in Tagum City.
Likewise, these efforts of the nominees inspired local fisherfolks to help protect their area of responsibility. With them working hand in hand, Tagum City is definitely “SEACURed”.
Congratulations to Tagum CENRO with its I’M SEAcue program for being awarded as the CSC Pagasa winner for group category this year.
