Exposed Aggregate Concrete in Denver, CO
Natural stone texture that’s slip-resistant, durable, and built to handle Colorado’s climate.
Denver’s Exposed Aggregate Concrete Contractors
Exposed aggregate concrete is one of the most practical and attractive finishes available for driveways, patios, pool decks, and walkways. By washing away the top layer of cement paste while the concrete is still fresh, the natural stone, gravel, and pebble aggregate inside is revealed — creating a beautifully textured surface that looks like it belongs in the landscape.
At Denver Stamped Concrete Co., voted Denver’s best concrete contractor five years in a row, we install exposed aggregate concrete throughout the Denver metro. It’s tough enough to handle Colorado winters, attractive enough to boost your curb appeal, and practical enough to be one of the most slip-resistant finishes you can choose.
What Is Exposed Aggregate Concrete?
Standard concrete has a smooth cement paste surface that covers the stone aggregate mixed inside. With exposed aggregate, a surface retarder is applied before the concrete fully cures, which slows the hardening of the top layer. The paste is then washed or brushed away, revealing the decorative aggregate — river pebbles, crushed granite, quartz, or other stones — embedded in the surface.
The aggregate can be chosen for color, size, and texture. River pebbles give a smooth, natural look. Crushed granite adds sparkle. Larger aggregate creates a bold, heavily textured surface. We’ll help you choose the right aggregate for your project during your free consultation.
Where We Install Exposed Aggregate in Denver
Driveways
Exposed aggregate is one of the most popular driveway finishes in Denver. It holds up to vehicle traffic, handles freeze-thaw cycles well, and looks far more attractive than plain concrete or asphalt.
Patios
The natural, organic look of exposed aggregate fits perfectly in Colorado landscaping. It’s comfortable underfoot, stays cooler than dark surfaces in summer sun, and requires minimal maintenance.
Pool Decks
Exposed aggregate is one of the best pool deck finishes for slip resistance — the textured stone surface provides excellent grip even when soaking wet.
Walkways & Paths
Create a beautiful, safe path through your yard or from the driveway to your front door with an exposed aggregate walkway that coordinates with your landscape.
Steps & Entries
Exposed aggregate on front steps and entryways is both attractive and practical — the texture provides traction year-round, including icy Colorado winters.
Decorative Borders
We use exposed aggregate as a contrasting border around stamped concrete patios and driveways — the texture and natural stone color creates a beautiful frame.

Our Exposed Aggregate Installation Process
- Consultation & Aggregate Selection We discuss your project and help you choose the right aggregate type, size, and color to match your home and landscape.
- Site Preparation We excavate, grade, and prepare a compacted aggregate base to ensure proper drainage and a stable foundation.
- Forming & Reinforcement We set forms and add rebar or fiber reinforcement appropriate for the application.
- Concrete Pour We pour the concrete mix — which already contains your chosen decorative aggregate throughout.
- Surface Retarder Application A chemical retarder is applied to the surface to slow curing of the top paste layer while the slab beneath hardens.
- Aggregate Exposure At the right time, we pressure wash the surface to remove the cement paste and cleanly reveal the aggregate beneath.
- Sealing Once fully cured, we apply a quality sealer to protect the surface, enhance aggregate color, and simplify maintenance.
Frequently Asked Questions
Is exposed aggregate concrete good for Colorado winters?
Yes — it’s one of the best choices for Colorado. The textured surface provides traction on icy days, and because the aggregate extends through the full depth of the slab, freeze-thaw damage stays on the surface level rather than penetrating deeply. Proper sealing is important to protect the surface from de-icing chemicals, which we include with every install.
Is exposed aggregate slippery when wet?
Exposed aggregate is one of the most slip-resistant concrete finishes available. The protruding stone aggregate creates natural grip that performs well even when wet — which is why it’s a top choice for pool decks and walkways.
How do you maintain exposed aggregate?
Maintenance is minimal. Sweep or blow off debris regularly, rinse with a hose as needed, and re-apply sealer every 2–3 years. Avoid using metal snow shovels on the surface, which can scratch the aggregate. A plastic shovel or snow blower is best for winter maintenance.
Can exposed aggregate be combined with other finishes?
Absolutely — and it looks great. We frequently use exposed aggregate as a border around stamped concrete patios or driveways, or as a transition strip between different surface areas. The natural stone texture pairs beautifully with stamped patterns and plain concrete sections.
