Coastal Protection

Sustainable, effective & proven nature-first Coastal Protection

Our sea levels are rising at an alarming rate, with projections estimating a 3-foot rise in San Francisco by 2100 and coastal areas worldwide facing increasing threats of flooding, erosion, and destruction. Every year, the ocean encroaches further inland, putting communities, infrastructure, and marine ecosystems at risk.

The challenge? Coastal defences that not only safeguard shorelines but also work in harmony with nature. At ARC Marine, we’ve engineered a sustainable, nature-inclusive solution that shields coastlines while fostering marine biodiversity. Our Reef cubes break the force of incoming waves, protecting vital coastal infrastructure while enhancing habitats for marine life.

Coastal Protection Needs to Evolve
With sea levels rising at 0.44cm per year, the global demand for effective shoreline defence is more urgent than ever. Traditional seawalls and hard engineering solutions often accelerate erosion and disrupt marine ecosystems – creating more problems than they solve.

ARC Marine is changing the game. By integrating nature-inclusive design into coastal protection, we create solutions that reduce wave energy, stabilise shorelines, and enhance biodiversity – ensuring that coastal infrastructure is both protected and regenerative.
