AMATEC

Amatec is a construction-technology startup that developed High-Density Gypsum (HDG), branded CeleStruct -- a patented, phosphogypsum-based replacement for concrete with a much smaller carbon footprint, curing time as fast as one hour, and lower cost than concrete or wood framing without compromising strength. The company's rapid-setting prefabricated wall and floor panels target homebuilders seeking climate-resilient, disaster-resistant construction that can be produced and installed significantly faster than traditional methods.
