Exposed Aggregate Concrete
 
 
Exposed aggregate concrete is a form of decorative concrete achieved by removing the top layer of cement paste and revealing the underlying aggregate.
The decorative aggregate now becomes a very durable, skid-resistant surface that is great for sidewalks, driveways, pool decks, and patios.
 
MONOLITHIC – The aggregates are batched right into the concrete truck at the concrete plant. This is the easiest and most common method.  There are different grades of small pebbles available to create different effects and textures.
SEEDED – Immediately after the concrete is placed the decorative aggregates are broadcast, or hand placed, onto the surface of the concrete and floated in by hand.
OVERLAY – This method is used on existing concrete that is in good shape. Aggregates are mixed into the overlay topping material and applied to the old concrete to give it a new look.
 
 
The “secret” to exposing the aggregates is keeping the top layer of cement paste soft while the underlying concrete hardens. This is done by spraying on a surface retardant immediately after installing the concrete and aggregates.
Many types of aggregates are available, large and small, colored, round, plus many more.  The textures blend well with other decorative concrete and it requires very little maintenance other than occasional cleaning and resealing every few years.
When compared to other decorative concrete styles, exposed aggregate cement is a lower cost method to having a terrific looking decorative concrete look.
