Premium Exposed Aggregate Concrete in Calgary
Looking for a concrete finish that combines beauty with functionality? Exposed aggregate is Calgary's premier choice for driveways, patios, walkways, and pool decks. This decorative concrete technique reveals natural stones embedded in the surface, creating a stunning, textured appearance that's both slip-resistant and incredibly durable.
What is Exposed Aggregate?
Exposed aggregate concrete is created by removing the top layer of cement paste to reveal the decorative stones (aggregate) beneath. The result is a beautiful, textured surface featuring natural river rock, granite, quartz, or colored stones that add character and visual appeal to any outdoor space.
Perfect Applications:
- Driveways and approach areas
- Patios and outdoor entertaining spaces
- Pool decks and walkways
- Sidewalks and garden paths

Exposed Aggregate FAQ - Calgary
Common questions about exposed aggregate concrete installation, costs, and maintenance.
Exposed aggregate concrete in Calgary typically costs $12-$18 per square foot, about 20-30% more than standard concrete but significantly less than pavers or natural stone. Costs vary based on aggregate type, project size, site access, and complexity. We provide detailed quotes including all materials, labor, and sealing.
Exposed aggregate reveals real stones embedded in the concrete surface for a natural, textured look. Stamped concrete uses patterns pressed into the surface to mimic stone, brick, or tile. Exposed aggregate offers better traction, hides imperfections better, and provides authentic texture, while stamped concrete offers more pattern variety and can replicate specific designs.
No, exposed aggregate is one of the most slip-resistant concrete finishes available, making it ideal for Calgary's winters. The natural stone texture provides excellent traction even when wet or icy. This makes it perfect for pool decks, walkways, and driveways where safety is a priority.
With proper installation and maintenance, exposed aggregate concrete lasts 20-30+ years in Calgary's climate. The key is quality installation with proper base preparation, reinforcement, drainage, and regular resealing every 2-3 years. The exposed stones are incredibly durable and won't wear down under normal traffic.
Yes, sealing is essential for exposed aggregate in Calgary. Sealer protects against moisture infiltration, freeze-thaw damage, salt damage, staining, and enhances stone colors. We apply two coats of commercial-grade sealer after installation and recommend resealing every 2-3 years for optimal protection and appearance.
Yes! You can choose from various aggregate types and colors including natural river rock (gray/tan), granite (gray/pink/black), quartz (white/cream), basalt (dark gray/black), or colored decorative stones in red, blue, or gold tones. The aggregate selection dramatically changes the final appearance to complement your home.
You can walk on exposed aggregate after 24-48 hours. Light vehicle traffic is safe after 7 days, but we recommend waiting 10-14 days for heavy vehicles. The sealer needs 24-48 hours to cure before use. Full concrete strength is reached at 28 days. We'll provide specific timing based on weather conditions.
Absolutely. Exposed aggregate performs exceptionally well in Calgary winters. The textured surface provides excellent traction on ice and snow, the sealed surface resists salt damage and freeze-thaw cycles, and the natural pattern hides de-icing salt residue better than smooth concrete. Use concrete-safe de-icers for best results.
Maintenance is simple: 1) Regular sweeping and washing with garden hose, 2) Reseal every 2-3 years with quality concrete sealer, 3) Use concrete-safe de-icers in winter, 4) Prompt cleanup of oil or chemical spills, 5) Avoid metal shovels that could chip stones. Pressure washing annually keeps it looking fresh.
Yes, exposed aggregate can be repaired, though matching the stone pattern and color can be challenging. Small cracks can be filled and resealed. Larger damage may require cutting out sections and patching with matching aggregate and color. Proper installation and maintenance minimize the need for repairs.
