Cement has a giant carbon footprint and is the most expensive component in today's concrete masonry. Watershed Materials, with the help of the National Science Foundation, has developed proprietary mix designs to produce durable, resilient, affordable, and beautiful masonry with less cement.

Our technology unlocks the strength in the minerals all around us - limestone, granite, rhyolite. Rock forms in nature over the course of millions of years as pressure fuses loose grains into solid stone. Watershed Materials has developed technology to activate this process in seconds rather than millennia.

Watershed Materials' market-ready product - Watershed Block - offers up to a 50% reduction in cement and a 65% reduction in embodied energy compared to conventional concrete masonry. Watershed Materials' geopolymer technology and lime slag mix design offer a future of zero cement.
