That is not a rounding error. It is a wedge.\u003c\/p\u003e\n\u003cp\u003eSo it rains, and water runs along the slab and finds the crack, because the crack is the lowest path available. The temperature drops overnight. The water inside freezes and pushes the two faces apart by a fraction of a millimetre. By morning it has thawed, the gap is very slightly wider than it was, and so it holds a little more water the next time.\u003c\/p\u003e\n\u003cp\u003eRepeat that forty or fifty times across one winter and you no longer have a hairline. You have a gap you can get a finger into, with crumbling edges. Repeat it for three winters and you have a section of slab that has broken free and started to move.\u003c\/p\u003e\n\u003cp\u003eSealing it on a dry afternoon costs a few dollars and twenty minutes.
