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.
What does Physical Weather mean?

Can you repair cracks in sidewalks yourself?
yes.Cement sidewalks can provide a nice looking addition to a home and they aren't just attractive, they also add value to a property. Unfortunately, a characteristic of cement that many people aren't aware of, is it's porous and it will absorb water. Over the seasons, water can get into the surface of a cement sidewalk and with the melting and freezing cycles the moisture can actually cause cracks in the cement. Luckily fixing cracks in a cement sidewalk isn’t a difficult job (it's well within the skill set of most homeowners) and the tools and supplies are readily available at your local home store.
