What are the pros and cons of brick walkways?

Brick walkways are very common in houses nowadays, because of their many advantages over other materials. One good thing about them is that they are very durable. They will last a long time, so you don’t have to repair them regularly. In connection to this, since they are very strong, they require less maintenance.  And in the event that they do need to be repaired, it is very easy to just take out the damaged brick and replace it. However, they also have their disadvantages and one is the cost. They can cost a lot more than concrete for example. Brick walkways can also sink in time, when the sand foundation erodes, making it quite an ugly sight.
