Reef Cubes®

Reef Cubes® are building blocks that can accelerate reef creation through its nature inclusive design, developed by the company ARC Marine.

The company believes that the blue economy's successful management is crucial for oceans to provide the ecological benefits that our world requires to thrive and ensure a sustainable future. Therefore, it aims to become an industry pioneer in nature-inclusive designs and long-term reef stewardship by developing a  model that anyone can adopt.

• The Reef Cubes® are entirely made from an eco-friendly concrete mixture with added sustainable reinforcement to guarantee that they last and positively affect the oceans. 
• The company uses a new Portland replacement cement group with low-carbon and uses 100% recycled sand and aggregate. 
• The cubes are hollow and stackable with a dovetail keying system. They are often characterized as 'Lego-like'-creating endless possibilities through stacking formations and resulting in dense, complex marine ecosystems that can be adapted to specific organisms. 
• The cubes also have advanced casting techniques that generate surface textures that replicate the features of natural reefs and niches that, in turn, enhance biological recruitment.

The cubes are available in 1 m³, 0.5 m³, and 0.25 m³. They are suitable for a wide range of applications such as offshore wind turbine and cable safety, pipeline and oil rig protection, coastal defense, eco-tourism, MPA/MCZ (Marine Protection Zones/ Marine Protection Areas) disincentives, and underwater reef systems where natural reefs have been damaged.

Reef Cubes®  is an award-winning patented innovation. It can provide habitat complexity, food, shelter, and act as nursing or spawning ground for various aquatic species, boost the commercial fish stock, promote carbon sequestration, increase biodiversity to preserve species, improve water quality, stimulate biogenic reef creation, and involves zero plastic.

The technology can quickly establish reef habitats and become a resilient incubator for marine biodiversity and benefit the marine ecosystem and environment.
