Sand Castle Holds Up A Car! - Mechanically Stabilized Earth
Dirt is probably the cheapest and simplest construction material out there, but it's not very strong compared to other choices. Luckily geotechnical engineers have developed a way to strengthen earthen materials with almost no additional effort - Mechanically Stabilized Earth (aka MSE or Reinforced Soil). If you look closely, you'll see MSE walls are everywhere. Thanks for watching, and let me know what you think!
