Stabilize shorelines, dissipate wave energy, and support thriving marine ecosystems.
Natrx ExoForms provide a nature-based solution that protects both shorelines and local ecosystems. Their nature-based design provides habitat for coastal life to thrive, in addition to wave dissipation, sediment capture, and more. Each ExoForm is modular, flexibly adapting to site and aesthetic requirements. As local habitat takes up residence in the ExoForms, the shoreline protection system offers even greater performance.
Manufactured in Louisiana, USA.
