About Exposed Aggregate Finishes
Exposed aggregate concrete reveals the natural beauty of stone aggregate within the concrete mix, creating durable surfaces with distinctive visual appeal. This finish is popular for commercial plazas, walkways, and exterior areas where both durability and aesthetics matter.
The exposed aggregate process involves careful timing: concrete is placed and finished normally, then the surface cement paste is removed to reveal the aggregate beneath. This requires experienced crews who understand the timing window and technique that produces consistent, attractive results.
Aggregate selection determines the final appearance. We offer various stone types, sizes, and color combinations to achieve the desired aesthetic. Custom aggregate mixes can incorporate specific colors or stone types to complement architectural design.
Commercial exposed aggregate applications include building entries, outdoor dining areas, pedestrian plazas, and decorative bands within larger paved areas. The textured surface provides slip resistance while the exposed stone creates visual interest that standard finishes cannot match.

Frequently Asked Questions
What aggregate options are available for exposed finishes?
We offer a range of natural stone aggregates in various sizes and colors: earth tones, grays, reds, and custom blends. We provide samples showing different aggregate options to help select the right combination for your project.
How does exposed aggregate compare to standard concrete for durability?
Exposed aggregate is as durable as standard concrete with the same mix design. The exposed surface is actually more resistant to surface abrasion than smooth concrete. Proper sealing extends life and enhances appearance.
Does exposed aggregate require special maintenance?
Exposed aggregate benefits from periodic sealing to protect the surface and enhance color. Regular cleaning removes debris from the textured surface. Maintenance requirements are similar to other decorative concrete finishes.
Can exposed aggregate be used for vehicle traffic areas?
Yes, with appropriate mix design and thickness for expected loads. The textured surface provides excellent traction. We commonly use exposed aggregate for parking areas where decorative appearance is desired.
How do you control the consistency of exposed aggregate finishes?
Consistency requires proper aggregate distribution in the mix, careful timing of surface treatment, and uniform depth of exposure. Our experienced crews monitor these variables throughout the pour to achieve uniform results.
