Rhizolith Island Prototypes
Rhizolith Island - A Floating Concrete Structure, is a prototype using advanced high performance concrete technology for a breakwater constructed in Cartagena, Colombia in October 2016.
The island investigates structures built with advanced concrete technology to revitalize depleting mangrove forests along vulnerable shorelines with ongoing flooding. We speculated and experimented with new high-performance concrete technology from CEMEX, using digital design and innovative fabrication techniques that hybridize the qualities of different concrete mixes in one structure. The prototype aims to use new design and technology to strengthen ecological performance and the public interface of a new typology for coastal infrastructure.
Rhizolith Island protects and revitalizes shoreline communities that suffer from flooding due to lack of mangrove forests that have depleted due to urban development. Where mangrove forests once naturally controlled sediment and shorelines from erosion, the proposal’s objectives are to repopulate those mangrove forests. The design of the elements ensures mangrove seedlings stay above water as roots grow to the seabed. Due to these sites being frequented by tourists, the city wants to provide a resilient and soft infrastructure that not only protects mangroves but also aesthetically enhances the shoreline.
The unique and innovative fabrication technique, coined ‘Pop-Up Concrete,’ was used conceptually as a way to fold a flat piece of formwork into a complex, folded geometry that makes the elements stronger and more stable. This was ONLY achievable with new concrete mixes that range from high-strength concrete to create a strong outer shell, to a lightweight floating concrete filling for buoyancy and a pervious concrete core that holds the mangrove seedlings and the medium needed for growth.
