Digging Out An Underground Workshop

[Michael] of Teaching Tech moved, and with a large crawlspace under the house, he decided to turn it into a workshop.

There were a few challenges that needed to be addressed first. He had to dig out the crawlspace to provide a level surface, though the depth was limited by the concrete footers the building stands on. The house is sitting on and around large amounts of limestone, which is excellent from a stability standpoint but causes problems for [Michael]. Water can easily travel through limestone, meaning it ends up in his newly dug-out crawlspace. He dug trenches for water to exit and laid down gravel. After a few attempts to level the floor, he found some recycled plastic floor mats and finally got them where he liked them.

Wheeling his tools down a long and steep hill to the shop looks like most of the challenge. But with a few additions to the shop, like hard tube dust extractions and a french cleat system, he has an incredibly functional dedicated shop space.

If your crawlspace is too small for people, a tiny remote-controlled forklift could turn it into the storage space you need.

Extraterrestrial Excavation: Digging Holes On Other Worlds

We humans are good at a lot of things, but making holes in the ground has to be among our greatest achievements. We’ve gone from grubbing roots with a stick to feeding billions with immense plows pulled by powerful tractors, and from carving simple roads across the land to drilling tunnels under the English Channel. Everywhere we go, we move dirt and rock out of the way, remodeling the planet to suit our needs.

Other worlds are subject to our propensity for digging holes too, and in the 50-odd years that we’ve been visiting or sending robots as our proxies, we’ve made our marks on quite a few celestial bodies. So far, all our digging has been in the name of science, either to explore the physical and chemical properties of these far-flung worlds in situ, or to actually package up a little bit of the heavens for analysis back home. One day we’ll no doubt be digging for different reasons, but until then, here’s a look at the holes we’ve dug and how we dug them.
