The company was developed as a division of Grein, an Austrian company that was founded in 1856 by Ernst Grein. Since being established, the company has grown from a small stoneworking operation in Graz to an international company now being run by its sixth generation.
Grein Italia started with one building and added a second a few years later. It now has 30,000 square meters of space, including 11,000 square meters enclosed, and it imports blocks from around the world. The company's philosophy is to combine Austrian and German mentality with Italian style, according to Michael Cramer, one of Grein Italia's directors.
