Exposed Aggregate Concrete in Oregon: Costs, Benefits & Best Uses
Exposed aggregate concrete is the Pacific Northwest's favorite decorative concrete finish — and for good reason. Its natural stone appearance, excellent slip resistance, and durability in wet conditions make it the ideal choice for Oregon driveways, patios, walkways, and pool decks.
What Is Exposed Aggregate Concrete?
Exposed aggregate concrete is created by removing the top layer of cement paste to reveal the decorative stone, gravel, or pebble aggregate beneath. The result is a textured, natural-looking surface that blends beautifully with Oregon's Pacific Northwest landscape. Popular aggregate choices in Oregon include river rock, basalt, quartz, and recycled glass.
- River rock aggregate — most popular in Oregon
- Basalt aggregate — Central Oregon aesthetic
- Quartz aggregate — sparkles in sunlight
- Recycled glass aggregate — eco-friendly option
- Seashell aggregate — coastal Oregon homes
Benefits of Exposed Aggregate Concrete in Oregon
Exposed aggregate is particularly well-suited to Oregon's climate and lifestyle. Its textured surface provides superior traction in wet conditions — a critical safety feature given Oregon's rainy winters. It's also highly durable, low-maintenance, and resistant to the freeze-thaw cycles that can damage smoother concrete finishes.
- Excellent slip resistance — critical in Oregon's wet climate
- Natural aesthetic that complements Pacific Northwest landscaping
- More durable than stamped concrete in freeze-thaw conditions
- Low maintenance — no resealing required as frequently
- Hides dirt, tire marks, and minor staining well
- Adds significant curb appeal and home value
Exposed Aggregate Costs in Oregon
Exposed aggregate concrete costs $8–$14 per square foot installed in Oregon, compared to $4–$7 for standard broom-finish concrete. The premium is worth it for high-visibility areas like driveways and front walkways where appearance and safety matter most.
Exposed Aggregate vs. Stamped Concrete in Oregon
Both are excellent decorative concrete options, but they serve different purposes. Exposed aggregate excels in wet, high-traffic areas where slip resistance is paramount. Stamped concrete offers more design flexibility and can mimic specific materials like brick or flagstone. Many Oregon homeowners use exposed aggregate for driveways and walkways, and stamped concrete for covered patios.
