Reefmasons develops next-generation 3D substrate technologies that accelerate reef recovery through both natural and assisted processes. Our patented designs support coral settlement, enhance habitat structure, stabilize substrates, and securely host translocated corals and fragments. Developed with support from NSF and DARPA Reefense, our solutions are field-tested, scalable, and deliver step-change improvements in coral establishment and early survival, enabling nature-based and hybrid approaches for reef restoration and coastal resilience.
