Reef Cubes® & Marinecrete - Eco-friendly concrete-like building blocks that allow every subsea and coastal projects to help rebuild marine habitat sustainably

Reef Cubes® (RCs) are versatile cube-like marine structures that protect subsea and coastal assets, or can be used as moorings, but also intentionally benefit nature by providing hard substrate and habitat complexity. They are made from 98% recycled materials using an innovate marine non-toxic binder (Marinecrete), and have a 90% lower carbon footprint than traditional Portland cement based alternatives. They are proven to enrich biodiversity and abundance due to their size, shape, surface pH, complexity and internal chambers, which rapidly become colonised and used as spawning and nursery grounds. Every marine project can now leave a positive marine legacy by switching from Portland cement-based products to low carbon footprint Marinecrete technology that contains zero plastics, and they are designed to be left in-situ forever, removing high decommissioning cost risks. RCs have the potential to reduce the life cycle cost of subsea mattress cable protection by upto 50%.
