Seeded concrete aggregates give a good alternative to basic broom or exposed concretes and are commonly used for walkways, patios and driveways. Seeded concrete is a process by which small decorative stones are embedded into prepared concrete. The top layer of the concrete is then washed away exposing the stone color.
There are a few different stone color options that are available for different design aesthetics. In Northern California the most commonly used stones are Mexican Pebbles, Pami Pebble, Salmon Creek Pebbles and Red River Rock Pebbles. See the photos below-
