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 expose the rock beneath in a uniform matter, so any spalling that may still happen is much less evident. If you have a normal driveway broom driveway and it’s spalling, it cannot be turned into an exposed aggregate driveway. This is because exposed aggregate concrete mixes have more rock than typical concrete mix designs, smaller rock and the rock has a high content of natural round rocks, sandblasting a normal mix will result in bald sandy spots and you will usually not get a consistent exposed look.

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.
