-------------------------------------------
SFWIW, there is/was a granite quarry on the west side of
Kelleys Island, one of the Lake Erie Islands, located in the
western end of Lake Erie.

Every fall they would drill a line of holes in the granite, then fill
the
holes with water and wait for winter to do it's work by freezing
the water in the holes and splitting the granite.

Water expands 1.04% by volume when it freezes and forms ice.

Does sound like much, but it was enough to split the granite to be
quarried during the following season.


Another, similar, technique is to fill the holes with dry, wooden, pegs. Add
water.
