They are called Wedges and shims or (plugs and feathers.)


They would be a good alternative to blasting agents.

Click on the on - line catalog, then go to Wedges and Shims.
I ordered 10 - sets for a 1" hole X 6" deep.
I received them from UPS and they look like quality materials.
I can't wait to use them.
I also noticed they have a new tool called - Hand splitting wedges,
these wedges are placed in seams or crevices, then simply hit with a hammer
in a sequence to split the rock, no drilling required, they come in different sizes,
thickness, and lengths.
