removes the cement matrix from the surface of the concrete exposing the
aggregates. Finishes range from light to heavy exposure.
Sandblasting aggregates can produce a heavy or fine
aggregate exposure. In addition, some fields that are side by
side, or in a pattern, can be sandblasted to different exposure
levels for an interesting effect.
Sandblasting creates a similar look to washed
aggregate but is done after 30 days.
