Haydite Production as depicted in a brochure from the late 1930's



Stephen Hayde invented and patented the method of making a structural grade lightweight aggregate early in the twentieth century. The process uses a rotary kiln to pyro-process and expand clay, shale or slate. The end product is a strong and durable lightweight aggregate used in numerous types of construction throughout the world.

Hayde named the product after himself. Although the original patents have long since expired, the term "Haydite" is used by several companies in marketing their expanded shale lightweight aggregate.
