Exposed Aggregate is a concrete and stone mixture that produces a surface similar to natural pebble. It provides a non-skid surface that is perfect for driveways, pool decks, walkways and steps. It's natural look can be enhanced when used along with traditional or colored concrete. Stones used in this process are typically small, smooth river rock about the size of a pea to a quarter.

Process

1. The ground is excavated, leveled and compacted.
2. The concrete-stone mix is poured into the prepared area and a retarder is painted onto the surface.
3. The stone is exposed by washing down the surface.
4. After the area has cured, it is sealed with an acrylic-based sealant to bring out the color and to protect it from the elements.
