It's easy to forget just how much rock there is integrated into buildings. I saw a literal mountain being eaten away by aggregate suppliers to provide gravel for various industrial uses. A closer look at pavement, cement or asphalt, reveals the mix of random rocks thrown in.
Founded in Switzerland in 1912, Holcim is one of the world's leading suppliers of cement and aggregates (crushed stone, sand and gravel). We also supply ready-mix concrete and asphalt, and provide related services.
