"Called the substance that became the building block of civilization, this episode follows the varied uses of concrete from Roman times to the present."
"This is the definitive chronicle of the substance that changed the world. It is literally the building block of civilization. Without concrete, life as we know it would not exist--our cities, roads and epic public works would not be the same, our way of life likely impossible. From the earliest formulations to epic works like the Hoover Dam to the technological advances that are letting this humble material take on compelling new forms and uses, Modern Marvels mixes up a fascinating blend of history, engineering and cultural observation to tell the story of concrete."
"This documentary uses history, engineering, and cultural observation to tell the story of concrete. Through narration, interviews, photos, and archival film footage, it explores concrete from its earliest days to its contemporary innovations."@en
