Color and stain are also a consideration when specifying concrete. Concrete can be stained after drying or color can be added to the mix before being poured into place. Textures can be applied to the concrete surface, either in the way the concrete ﬁnishers smooth or broom-brush texture to the surface, or seed it with rock salt while the concrete is still wet to produce another range of textures, or add rock or other material for color and texture to the ﬁnished surface. There are other possibilities for the landscape architect to consider when specifying concrete pavement, including the use of porous concrete to enable surface water to inﬁltrate the underlying soil. It is possible to create a variety of surface patterns on concrete, including emulating
the look of bricks, ﬂagstones, and other patterns. These patterns are created by applying stamp patterns to wet concrete.
