Why are sidewalks are usually built with cracks in them?
Okay, so think about it. If a sidewalk was not built with cracks in it, then eventually weathering and erosion would cause cracks anyway. Then, whenever it rained, rainwater would get in the cracks. Stay with me now! If the temperature then dropped below the freezing point (32 degrees F, 0 degrees C), then the water in the cracks will freeze. When water freezes, it expands, which would exert pressure on the sidewalk, eventually causing the sidewalk to further crack or even split in two! If a sidewalk already has minimal, purposefully placed cracks in it, then the damage can be minimized.
