Exposed aggregate driveways combine decorative appeal with practical winter performance. The washed-back surface reveals embedded stone, creating natural traction and visual depth without the maintenance demands of stamped finishes. We start every project with a free written estimate and site consultation.
Exposed aggregate occupies the practical sweet spot between plain concrete and high-maintenance decorative finishes. The stone matrix visible on the surface provides visual interest and authentic texture, while the underlying slab remains a standard air-entrained pour designed for Boston's freeze-thaw cycles.
Winter grip is the standout feature. Unlike smooth or broom-finished surfaces, the exposed stone creates natural traction that keeps vehicles and pedestrians secure on slopes and icy conditions. The texture also masks tire marks and salt staining better than flat finishes, so your driveway looks fresher longer.
Compared to stamped concrete, exposed aggregate requires less frequent sealing and avoids the pattern-wear issues that stamped surfaces develop. You get decorative character without the commitment. The concrete driveway base is built the same way every time, with proper grading and reinforcement.

Installation sequence
Building an Exposed Aggregate Driveway Step by Step
Select stone and depth
We review aggregate options with you, pea gravel for subtle texture, larger stones for bold character, and determine how deep the wash-back will go to achieve your preferred surface feel.
Place and level the slab
Air-entrained concrete is poured to the forms, screeded level, and allowed to set to the precise stage where the surface can be washed without dislodging stones or leaving cement residue.
Wash and brush the surface
Using controlled water pressure and brushing, the top cement layer is removed to expose the stone aggregate to the depth we planned, revealing the finished texture.
Cure and seal the finish
After full curing, a protective sealer is applied to lock in the stone, repel water and de-icing salt, and enhance the natural colour of the aggregate.
How it compares
Exposed Aggregate Against Other Finishes
Exposed aggregate outperforms a plain brushed finish on aesthetics while staying simpler than stamped concrete. Stamped surfaces offer pattern detail but demand more frequent sealing and show wear in high-traffic zones. Exposed aggregate hides wear naturally.
Adding integral colour to the base concrete deepens the visual effect without changing the texture profile. The stone selection itself influences tone, so we bring samples to your site so you can evaluate combinations in natural light. Regular driveway sealing keeps any finish protected.

Answers to common questions about texture, grip, maintenance and design options.
Because the stone surface gives natural winter grip and decorative texture without the higher upkeep of stamped concrete. For Canadian conditions, it is a hard-to-beat balance of look, grip and maintenance.
It has more texture than a smooth slab but is not aggressive underfoot. Most homeowners find it comfortable, and shovels glide cleanly across it once you get the angle. The stone size we choose tunes the feel.
Less often than stamped, typically every three to four years in Boston. The natural stone surface hides wear better and the sealer keeps water and salt out of the matrix between the stones.
Yes. The base concrete can be integrally coloured under the exposed surface, and the stone choice itself shifts the tone. We bring samples so you can see the combinations in daylight.
Somewhat. The timing of the wash-back has to be right, too early and you lose stones, too late and the surface stays cement-covered. We schedule the pour for weather that lets us time it cleanly.

Boston Homeowners on Their Exposed Aggregate Driveways
Exposed aggregate across the whole driveway. The grip in winter is the real win, our boots and the dog never slip on the slope coming down.

★★★★★
Picked a warmer stone tone to match the brick on the house. The driveway pulls the whole front of the property together and has hidden a season of use beautifully.

★★★★★
Lower upkeep than the stamped patio we did the year before. Same texture quality, less work, exactly what they explained on the estimate.
G. N.

★★★★★
Timed the wash-back perfectly. The stones are exposed to the depth we wanted, the joints are clean, and the seal has held through the first winter.
