Walls are used for many more reasons than just separating one section of something from another section. There are retaining walls that segment one elevation from another by strengthening the higher elevation and packing it with wall specific material. These walls which are used when necessary can also be made lovely to look at.

Stone walls offer a beautiful way of separating elements such as pool water from patio stone. Walls offer an exciting way of separating flowers from steps and elevations from becoming lost.
