Exposed Aggregate Concrete

The most common decorative concrete driveway in Calgary without a doubt is Exposed Aggregate Concrete. The popularity has not only to do with its attractive appearance but also its durable surface. Damage caused by frost and salt on typical driveways, which is the pealing and spalling, is not as evident on exposed aggregate concrete. Exposed aggregate concrete differs from other decorative concrete because the top surface is washed or blasted away to reveal the rock beneath in a uniform matter, so any spalling that may still happen is much less evident.

If you have a regular driveway broom driveway and it’s spalling, it cannot be turned into an exposed aggregate driveway. It is because exposed aggregate concrete mixes have more rock than typical concrete mix designs, smaller rock, and it has a high content of natural round rocks. Sandblasting a standard mix will result in bald, sandy spots, and you will usually not get a consistent exposed look.

Installing A Concrete Slab

The preparation of a slab for Exposed Aggregate Concrete uses the same process as described in our stamped concrete section, so please read that section for details about prep. To achieve the exposed aggregate look after the final set of a slab, we wash off the surface to expose the aggregate. The preferred method is always for use to clean aggregate is washing, however sometimes it’s not practical or an option, so we may opt to sandblast the surface to expose the rock, most often sandblast exposed steps. The process is a messy one, so any flowers adjacent to the work area should be transplanted until the new driveway is installed. If a new build, it’s always best to have the exposed work complete before final exterior finishing, such as a light stucco finish coat.
