As a young company, our passion is in wanting humans to interact with the marine world differently. We understand that as a species we need to grow and take up more space, but we aim to make our impact on the environment as minimal as possible. In fact, we want to give back more than we take out, this way the blue economy will keep on giving for generations to come!

For us, our work is our passion. As a group of professionals, we dedicate ourselves to the task given to us and provide a level of service which is unmatched. For that reason, we focus on what we enjoy doing and will not take part in projects which do not treat the marine environment with the utmost respect.
The building blocks to saving our oceans

In an effort to restore the tragic state the human race has left our oceans in, we decided to knuckle down and dedicate a huge amount of our time and research in coming up with an new and innovative solution, in an effort to rectify some of these ever-growing issues. The result, Reef Cubes.

Reef Cubes are hollow, stackable, adaptable and made almost entirely of concrete with the addition of some sustainable bonding ingredients to ensure they last indefinitely with minimal affect to the oceans. A keying system was later added to the Reef Cubes in an effort to make them almost ‘lego-like’, creating infinite possibilities for stacking formations and sea-life tunnels. Available in both 1m3 and 0.5m3, they are perfect for various applications including offshore wind turbines, trawler protection, coastal defence, diving sites and establishing underwater reef systems.

Thanks to our bespoke shippable moulding system, we are able to ship these products globally. This allows the end user to cast Reef Cubes in the moulds upon delivery and create as much habitat as required for the desired application.


"Based on the South West Coast of England, ARC Marine construct and design eco-engineered marine habitats. As marine engineering specialists, we have a dedicated marine science department, innovative product designers and a HSE commercial dive team.”
