I recently built a new shop for my custom woodworking business near Lewisburg, W.Va. The site I chose is not quite typical for a woodshop—it's within an old limestone quarry—but the price was right, it's within walking distance of our historic downtown, and the natural soundproofing of the quarry walls lets me run my chainsaw and band saw mill without bothering the neighbors.
The relatively flat bedrock floor also offered a solid base for a slab foundation. But before I could proceed with the formwork, I was faced with the challenge of removing about 10 cubic feet of limestone in a rear corner of what is now my shop, as well as taking out several ridges that ran through what would become my slab.
