Rainwater can penetrate the surface layers of porous rock and building bricks for example.
When the temperature drops and this water freezes it expands by about 10 per cent.
This causes the face of the stone or brick to crumble ,or 'spall'. Successive freezing events can reduce the rock to sand without any rolling or impact to it.
Expansion of ice.
You can see this effect when you take an ice tray out of the freezer. The ice block is too large for it's cube well and rises above the original level. This is why ice floats because it is 10 per cent less dense than the water surrounding it.
