Exposed aggregate concrete can almost be compared to a piece of granite or marble transformed by polishing: A plain, unremarkable surface has been stripped away to reveal the exceptional beauty lying beneath. In the case of concrete, that beauty is in the form of decorative aggregate, either natural or manufactured.

An exposed-aggregate surface is obtained by placing concrete and then removing the outer 'skin' of cement paste to uncover decorative coarse aggregate (either batched into the concrete mix or seeded onto the surface).

Because of its durability and skid resistance, an exposed aggregate finish is ideal for most flatwork including:

1. Sidewalks
2. Driveways
3. Patios
4. Pool decks
5. Plazas

An exposed-aggregate finish is also possible on concrete walls or tilt-up panels. Vertical applications include:

1. Decorative retaining walls
2. Architectural building facades
3. Sound barrier walls

Pros:

1. It looks natural and add extra value to your home.
2. The surface is rugged, non skid, and resistant to heavy traffic and weather extremes.
3. Many types and sizes of decorative aggregate are available to achieve unlimited color and texture variations.
4. Exposed aggregate is highly versatile and contrasts beautifully with plain concrete or other decorative treatments such as stamping, stenciling, staining, and integral coloring.
5. Little maintenance is required, other than sealing and occasional cleaning.
