Material Development - Syndecrete

     David Hertz invented Syndecrete in 1983, as a lightweight, durable, and environmentally friendly alternative to concrete.  Utilizing materials such as post-consumer carpeting and waste fly-ash from electric plants, Syndecrete has double the compressive strength of traditional concrete with only half the weight.  This allows Syndecrete to have creative uses such as signage, wall tile, decorative works, and even furniture.  Furthermore, by incorporating recycled material into the mixture, Syndecrete can form a stylish terrazzo that reflects the identity of the client: for example, vinyl records, CDs, and audio cassettes were saved from the landfill to be used for Rhino Records floor.  Likewise, Patagonia enlisted David Hertz to incorporate factory reject zippers and broken buttons to be used in Syndecrete in their Tokyo store.  

In 2006, David Hertz sold the Syndecrete technology to Headwaters, a $1.6 Billion public company.  In 2009, the subsidiary El Dorado Stone ceased production of Syndecrete, making it unavailable currently.  If you are interested in licensing the technology or other sustainable materials development, please reach out to our consulting services here.
