In 2023, 17 Reefblocks were installed in the Port of Rotterdam’s busiest shipping channel near Rozenburg, creating the modular Rotterdam Reef. These concrete blocks form the backbone of a living reef. Each block, measuring 3 meters in length and weighing 6 tons, is designed to withstand heavy wave impacts while fostering a vibrant underwater landscape. Featuring tunnels, shaded passages, and rough textures, the structure creates a dynamic ecosystem where fish, crabs, and shrimp can thrive, offering protection for both coastlines and marine life.

Reefblocks are supporting the biodiversity of the shipping channel: more species means cleaner water and a stronger ecosystem.
- A Haven for Marine Life: Monitoring shows the reef offers shelter to a variety of marine species, including fish, crabs, and shrimp.
- Boost in Biodiversity: The rough surfaces of the Reefblocks encourage the growth of shellfish and algae, leading to three times higher biodiversity compared to standard concrete.
- eDNA Research Insights: Studies confirm the Port of Rotterdam’s main channel serves as a crossroads for freshwater, saltwater, and migratory fish species. The Reefblocks support fish migration and naturally enhance water quality through filtration.
