When drilling a hole into a rock, filling it with water, and freezing it, why does it expand outward to break the rock rather than extrude out of the hole that was drilled?

Usually, the rock cools down from the surface to core. So the top of the water freezes first, essentially trapping the liquid under it so it cannot squirt out when freezing and expanding. Water has this property where it’s density is highest at 4deg C. So the bottom of the water is always last to freeze. Also see ice-fishing
