We all know the destructive power of earthquakes, hurricanes, and other forces of nature and while I was aware of expansive soils, I had no idea the amount of damage they cause. We at Alchemy-Spetec focus on industry education, so I am pleased to share this video about expansive soils from Grady Hillhouse at Practical Engineering.

Here's a text excerpt to whet your appetite...

"When most people think property damage, they think about natural disasters. But what if I told you there’s a slow-moving, geologic phenomenon that causes more damage in the United States than earthquakes, floods, hurricanes, and tornadoes combined?

Hey, I’m Grady and this is Practical Engineering. Today we’re talking about expansive soils.

Certain types of clay soils change their volume depending on moisture content. They swell when they get wet and shrink as they dry.  This is a microscopic mechanism where the shape and arrangement of the molecules actually change according to the amount of water mixed in. And large portions of the U.S. Gulf Coast and Great Plains have these kinds of soils. If you’re starting a foundation repair or road paving business, this is an important map for one very good reason – expansive soils break stuff."
