While some of the reasons for these cracks may seem obvious, understanding the underlying cause can help us to maintain our sidewalks better.

First, we must look at the material used to construct most sidewalks – concrete. Concrete is durable but not indestructible. Over time, it can and will expand and contract due to temperature changes. This causes the concrete to crack, especially when temperatures change suddenly. Cracks can also occur due to errors in its construction such as not reinforcing it adequately.
