Why Do Buildings Need Foundations?

Every building you've ever walked into is standing on something you will never see. In this video, I explain what a foundation actually does: why buildings need one, how it spreads the load, why the ground underneath matters more than the concrete, and what goes wrong when it fails, from cracked walls to the Leaning Tower of Pisa. Plus: how the Burj Khalifa stays up, and the one thing to do before you build. Chapters 00:00 What's under your house? 00:36 Buildings are heavy.
