Sealor is designed to address one of the hidden causes of coastal infrastructure failure: water moving through porous ground behind seawalls and other coastal assets. By stimulating the formation of new limestone within underground pore spaces, the technology helps strengthen and seal vulnerable ground, reducing water migration, erosion, flooding, and saltwater intrusion.
This Phase II award marks an important milestone in Sealor's journey from laboratory validation toward real-world deployment. It will support continued technology development, field validation, and pilot preparation in South Florida.
“Florida’s coastal infrastructure is often failing from the ground up,” said Dr. Alexander Suma, founder and CEO of Nexuma and Sealor. “By the time that cracks, erosion, or seawall collapse become visible, the underground damage may already be advanced. Sealor is designed to address that root cause by turning vulnerable, porous ground into a stronger, sealed, mineralized barrier — using a process inspired by nature.”

“Reducing the process time from months to days is a critical achievement for Sealor,” said Dr. Robert P. Smith, a research collaborator at Nova Southeastern University. “It brings the technology significantly closer to practical implementation and allows us to prepare for pilot projects that can demonstrate performance under real coastal conditions.”
