Non-Explosive Blasting

In an effort to keep Lewis Cabin as low to the ground as possible, a few areas of bedrock needed to be removed. As the volume of rock to be blasted was too low to justify bringing in a full-scale rock drill and blasting crew we settled on another option: non-explosive blasting.
This method involves drilling several holes in a specific pattern and depth with a hammer drill, mix the compound, fill the holes and wait patiently for the rock to fracture. No professionals, no permits, no problems.
In the pictures below, you can see the holes drilled in a grid and the rock after fracture. We then pried apart the chunks and the job was done.
