Reefs
Biomimetic substrates for jumpstarting native reefs — the natural solution.
■
Our coastlines are threatened by sea level rise and storm surge.
Long before seawalls and riprap, reefs — now in decline by over 50% — protected shorelines by reducing wave energy, filtering water, sequestering carbon, and creating living habitats that supported entire ecosystems. Our products work with reef-building organisms to rebuild this coastal defense infrastructure.

Featured Products
Reef Tile
The reef-generating building block for coastal protection
Patented Design
+ Beyond the footprint: Engineered to serve as a catalyst — oysters bridge outward, expanding reef formation beyond the tile itself.
+ Species-scaled surface texture: Grooves and pores specifically-optimized for species settlement
+ Integrated seagrass pockets: The only product on the market with built-in spaces for seagrass establishment.
+ Flexible configurations: Deployed in gentle curves or group patterns that follow your shoreline's natural contours.
+ Low-cost installation: Easy to deploy modular units (from 33 lb hand-placed units to larger units) deployable with small boats.
Proven Results
3rd party testing by the Virginia Institute of Marine Science in the Chesapeake Bay:
+ 50–100 oysters attach per tile in the first season alone
+ Jumpstart native reefs: stable multi-generational recruitment in subsequent years
+ Biodiversity surge: Immediate habitat upon installation, with shade and protection for crabs, fish, juvenile species, and seagrasses
+ Living infrastructure: Natural catch documented after just 1 year in field conditions
+ Wave attenuation: Increases shoreline erosion by dampening wave energy by up to 85% — like a natural reef — proven by computational fluid dynamics (CFD) modeling.
Specification
Dimensions: 12"L × 12"W × 8.5"H (30cm × 30cm × 22cm)
Weight: 33 lbs
Reef Disk
The versatile solution for maximum species recruitment, spat collection, oyster gardening, and research
Patented Design
+ Three surfaces: Optimized for target species.
+ Targeted Species: Optimized for oysters, mussels, corals, sponges and serpulids
+ Multiple deployment options: Insert between breakwater rocks, hang from docks, piers, buoys, or suspend on vertical/horizontal rope systems
+ Reef Rope systems: Pre-strung ropes in 10 ft or custom lengths with 3 surface variations; purchase ready-made or build your own
+ Removable and reusable substrate: Durable for repeated cycles after harvest
Proven Results
Baltimore Harbor, Boston Harbor, Lower Chesapeake Bay, and University of Florida field data:
+ 100% surface coverage within one year from natural catch
+ 3 layers of mussels in first-year testing
+ 85% oyster coverage with room for maturation
+ Rapid colonization across multiple marine environments
Specification
Dimensions: 3.5" (h) × 4" (d) with 1.25" center hole*
Weight: 5 lbs
*Flexible sizing: Larger models available
CaCO3 Concrete
MIT-tested marine concrete
Patented Design
+ Biomimetic Design: Formulated to match the oyster shell, coral skeleton, or other reef-building species
+ Eco-positive Formula: All natural ingredients and no chemical admixtures.
+ Biodiversity Support: Provides early stage nutrition to developing oysters and other reef-building organisms.
+ Increased Recruitment: Formula mimics an adult reef, sending chemical cues to attract oyster embryos and other beneficial species.
+ Flexible Scaling & Application: Works as a casting and 3D-printing concrete
+ Ocean Alkalinity Enhancement (OAE): Neutralizes surrounding ocean water p.H. to a safe haven of 8.2 (tunable to alternative levels upon request)
+ Lower Carbon footprint: Uses minimal cement and can be sourced locally, near any site.
Proven Results
Testing by Virginia Institute of Marine Science:
+ Multi-generational species growth: Provides a stable substrate for reef growth over subsequent years
+ Living infrastructure: Increased natural catch documented after just 1.25 years in field conditions
