Another application is removal of large rocks, or excavation in places where the bedrock is close to the surface. I recall seeing this done in Ridgefield, Connecticut some decades ago. The excavation was right next to a building and a mat was used to contain fragments.
Haha, as I read your comment I was thinking “yeah, like back in CT.” I saw this done in ridgefield as well. My friends property was basically all bedrock about 1’ under the topsoil.
