Brick walkways are generally more durable than concrete, but cost almost the same. Concrete will crack more easily, as compared to brick, so you have to be extra careful with the weight that it holds every day. In terms of design, however, concrete is more versatile, and can have different colors, textures and shapes. Since brick is installed and laid on an individual basis, the joints in between the bricks allow for adjustment when pressure is applied on the walkway, or when temperature changes cause the bricks to expand. A brick walkway will therefore be more practical for everyday use, especially if it is much exposed to harsh weather, and holds heavy weights all the time.
