Reef Cubes® - The Building Blocks Of The Ocean

Reef Cubes® are an award winning, patented innovation, developed and owned by ARC Marine. Their resilient and deceptively simple interlocking design makes them perfect for creating and restoring complex marine habitats whilst serving a dual purpose protecting subsea assets such as monopiles, cables, foundations and pipelines.

Surface texture – advanced casting techniques that create surface textures that replicate natural reef features and niches which in turn enhance biological recruitment

Concrete Matrixes

Reef Cubes® have been scientifically engineered and are manufactured from a marine friendly material which is the perfect substrate for marine flora and fauna to adhere to.  We use a new group of Portland replacement cements which are low-carbon and use 100% recycled sand and aggregate.

What makes our Reef Cubes® special?

less CO2 emissions

Reducing carbon emissions by 70% compared to the processes necessary to form Portland cement (CEMI)

Our aggregate and sand is 100% recycled material, a by-product sourced from the quarrying industry. All our materials are checked for impurities before manufacture to maintain the highest construction standards.

At least
less environmental impact

60% less impact on the environment due to the extraction of raw materials. Reef Cubes® enhances the biological sequestration of Carbon into the ocean.

The process used to form Reef Cubes expend less energy than traditional methods of concrete production, without compromising the durability needed in the marine environment.
