What Makes Concrete Rock Armour So Great?


Textured concrete surfaces provide artificial habitats for local marine life


Sensicrete® Marine mix reduces the amount of embedded carbon


Self-healing additive enables the marine structures to autonomously heal

“Late design changes meant that it was a test for us to keep everything on track, and meant that Modular Cubed had to be very flexible. We’ve been very impressed with the team, who were determined to deliver a quality job, no matter what.”
Mike McCormick – Bouygues UK
