Exposed Aggregate is the process of washing of the top surface layer of the concrete, to "expose" the aggregate or rock. There are two types: In-mix and Hand Seeded. Whichever you choose, both provide a natural appearance that compliment any landscape.
In-mix: In-mix aggregate is just that. The rock is pre-mixed into the concrete from the concrete plant. It typically comes in three colors: Overall grey, Earth tones, and Black/White.
Hand Seeded: Hand Seeded aggregate comes in bags and is casted by hand and embedded into the top layer of the concrete. It is available in a wide variety of colors.
