Why do sidewalks have blocks, instead of being solid?
In: 205
Bunch of reasons.
Ease. Sidewalks are usually too small for large cement or asphalt trucks to drive across and work on. Stones can be laid no matter the size of the path.
Practicality. Water, power and gas lines usually run beneath sidewalks. If there’s an issue or they need access for some reason, it’s easier and cheaper to take out stones than it is to break apart asphalt or cement and then redo it.
Aesthetic. Many people prefer the look of stones to a single solid slab.
Sidewalks also don’t need the durability of roads, since there are no cars driving over them. At least not as much or as fast.
