• RESTORING

    We restore damaged coral reefs using innovative Biorock technology, helping marine ecosystems recover and thrive in the face of environmental challenges.

  • PROTECTING

    Healthy reefs protect coastlines and marine biodiversity by creating sustainable habitats that strengthen coral resilience and promote long-term environmental health.

  • CONNECTING

    Telling the story of marine conservation through art.

    We connect people to the ocean through art, transforming underwater sculptures into living reefs that inspire creativity, awareness, and a deeper connection to nature.

What is the Biorock Technique?

Pioneered in 1979 by visionary scientist Wolf Hilbertz and marine biologist Dr. Tom Goreau, the Biorock technique is a groundbreaking approach to marine restoration. This innovative process uses a low-voltage electrical current to stimulate natural mineral growth on metal structures submerged in seawater. By placing a titanium mesh (anode) near the metal framework (cathode), the system promotes the accumulation of calcium carbonate and other minerals, creating a natural reef-like formation.

Powered by solar energy or a main power source, the Biorock process fosters the growth of corals, oysters, and other marine organisms, offering a sustainable solution for restoring damaged reefs and protecting coastlines. This cutting-edge technology enhances marine ecosystems while reinforcing coastal resilience—creating new life and safeguarding our oceans for future generations.

Biorock vs BioRocks

Project BioRocks blends creativity with conservation.

Founded by artist and marine enthusiast Ronald Duikersloot, BioRocks takes the innovative Biorock technique and gives it an artistic twist.

Instead of using plain metal structures, Ronald creates beautiful underwater sculptures that become living canvases for marine life.

These sculptures aren’t just art—they’re the foundation for coral growth and vibrant ecosystems. By applying a gentle, solar-powered electrical current to the metal artwork, minerals naturally build up on the surface, allowing corals and marine organisms to flourish. Over time, these sculptures transform into thriving reefs, teeming with life and beauty.

BioRockS is about more than just restoring reefs—it’s about inspiring people to see the ocean in a new way. Our underwater galleries connect art, science, and nature, showing how creativity can help heal the planet.

Project BioRocks St Maarten

Artist Ronald ‘Rusty’ Duikersloot builds and designs artificial reefs with art sculptures. By adopting the international acknowledged Biorock technique and working alongside the co-founding father Dr. Thomas J. Goreau (Globalcoral.org) an electrolyte system is placed on the sculptures generating natural limestone formations on the metal.

This technique closes the sculpture off for corrosion and has been proven to grow up to 5 x faster + making it up to 20 x more resilient against human and natural stress impact (source: Globalcoral.org/biorockcoralgrowth ).

Making it an ideal place to co-exist with the vibrant tourism industry. In time it is possible to even invite tourists in where they can help out, donate and leave the island as (certified) eco-tourist. But for now the artist is focussed on jumpstarting coral reefs and coral intervention programs in collaboration with the local experts. Home based in the Caribbean on the beautiful island of St. Maarten/ St Martin this is the perfect place to regenerate the ocean with his so called ‘Art That Matters’.

We literally jumpstart new coral reefs with art sculptures!
