Grow Oyster Reefs, LLC (GROW) is an early-stage women-owned Virginia enterprise that possesses patented and scalable concrete oyster substrate products poised to dramatically improve oyster reef restoration efforts globally. 

GROW’s aim is to manufacture and distribute these newly patented Concrete Oyster Reef Restoration Tiles (CORRT), Disks (CORRD) and CaC03 Concrete Mix. The market supporting the current oyster reef restoration effort is growing rapidly due to the invaluable role oysters play in mitigating climate change.


Evelyn Tickle inventor/owner

Evelyn attended Auburn University's Architecture School, then Southern California Institute of Architecture for her Master’s in Architecture, and subsequently taught for 8 years at University of Virginia's School of Architecture. She co-founded Tickle:Kitchin Design and Fabrication, winning the Rome Prize in Architecture for her innovative work. She spent a year at The American Academy in Rome, and her concrete creations were shown at the Academy and at Rome's Modern Museum of Art. She returned to Virginia to co-found another company (2002-2008), Pretty Hard Fine Concrete, a successful entrepreneurial business making concrete architectural wall panels, basins, fireplaces, bars, furniture for commercial and residential clients locally and nationally. Evelyn still lives in Charlottesville, Virginia and teaches architecture at nearby James Madison University where she is also Director of The Concrete Lab .

In 2008, Evelyn became inspired by biomimicry, and began a solo study of the concrete-like secretions of oyster reefs. Her experiments resulted in her proprietary CaC02 Concrete, a shell-less formulation chemically similar to oyster shells that she then used to invent a small tiles and cones that imitate the substrate of reefs. Concrete Reef Restoration Tiles (CORRT) can be used to start new oyster reefs or fill in gaps in deteriorating ones, for production as well as for scientific research. Evelyn recently launched Grow Oyster Reefs llc to produce these tiles, disks and CaCo3Concrete to be used in oyster farming, scientific research and oyster reef restoration work worldwide.
