There are three main categories of pavers available for walkway construction: Natural stone, Brick Pavers and Concrete Pavers.
The great benefit of using concrete and brick pavers for a walkway is the huge variety of shapes, size and glorious colors that you can select from. Because they are manufactured, the colors and shapes are almost endless. With natural stone, your color choice and shape is limited due to the fact that they are a natural product. But having said that, natural feel and natural look is what some homeowners would like to have in the outdoors.
