What are Concrete Sidewalks?
Concrete Sidewalks are 4″ or 6″ (depending on whether or not they also support vehicular traffic) thick concrete slabs formed and poured in square or rectangular flags. These flags tend to be 4–6′ wide and long, separated by expansion or control joints that allow for the natural growth and contraction of concrete due to heat and the elements. Sometimes sidewalks are reinforced with wire mesh for added tensile strength.
