> I'm slightly puzzled it doesn't get mentioned here. Has this knowledge been lost? Clearly not. He talked about soil compaction in earlier articles: In "Why SpaceX Cares About Dirt"[1] he talks about soil compaction through surcharge loading. In "What Really Happened At Edenville and Sanford Dams?"[2] he talks about how the lack of proper soil compaction was one reason behind the dam failures. In "Why Does Road Construction Take So Long?" he identifies soil compaction as one of the most time consuming parts of road construction. If anything he didn't talk about soil compaction in this article to avoid repeating himself. :) 1: https://practical.engineering/blog/2021/10/28/why-spacex-cares-about-dirt https://practical.engineering/blog/2021/10/28/why-spacex-car... 2: https://practical.engineering/blog/2021/10/14/what-really-happened-at-edenville-and-sanford-dams https://practical.engineering/blog/2021/10/14/what-really-ha... 3: https://practical.engineering/blog/2020/6/1/why-does-road-construction-take-so-long https://practical.engineering/blog/2020/6/1/why-does-road-co...
