Washed-back stone surfaces deliver traction and visual depth without the maintenance demands of stamped finishes. The aggregate sits just below the surface, creating natural grip for winter months and a decorative appearance that ages gracefully. We start every project with a free written estimate and site assessment.
Homeowners often face a choice: go plain and practical, or invest in decorative finishes that demand more care. Exposed aggregate splits the difference. The washed-back surface reveals the stone in the mix, giving your driveway visual character and natural traction without the resealing schedule of a stamped driveway.
The slab itself is built the same way as any concrete driveway in Oshawa: air-entrained mix for freeze-thaw cycles, proper base prep, and reinforcement. The finish is where the difference shows. Once the concrete sets to the right stage, we wash back the surface to expose the aggregate, then seal it to lock in colour and protect against salt and moisture.
Winter grip is a real advantage. The stone texture provides traction that a smooth or broom-finish slab cannot match, and the surface hides tire marks and minor wear better than flat finishes. For Canadian climates, this combination of looks and function makes driveway sealing the only routine maintenance you need.

The pour sequence
Building an Exposed Aggregate Driveway Step by Step
Select stone and colour
We review aggregate options with you, choosing pea gravel for subtle texture or larger stones for bold visual impact. Integral colour can be added to the base concrete for added depth.
Prepare and form the site
The subgrade is compacted, forms are set to grade, and the area is ready for the pour. Proper slope ensures drainage and prevents water pooling on the finished slab.
Pour and level the concrete
Air-entrained concrete is placed and screeded flat to the form lines. The timing of the next step depends on how the concrete sets, which we monitor closely.
Wash back the surface
At the precise moment, we apply controlled water pressure and brushing to remove the surface cement paste and reveal the stone. Too early and stones dislodge; too late and the surface stays covered.
Cure and seal
The slab cures fully before sealing. The sealer protects the stone matrix from water infiltration and de-icing salt, bringing out the natural colour of the aggregate.
How it compares
Exposed Aggregate vs Other Driveway Finishes
A brushed finish is simpler and cheaper, but offers no decorative appeal. Stamped concrete looks premium, mimicking stone or brick, but requires more frequent sealing and is prone to hairline cracks in the pattern. Exposed aggregate sits between them: more decorative than brushed, lower maintenance than stamped.
Coloured concrete can be combined with exposed aggregate for even more visual interest. The base colour shows through the washed surface, and the stone itself adds texture and depth. Whatever finish you choose, regular sealing extends the life and keeps the slab looking fresh. Visit the driveway hub to explore all your options.
Texture, grip, sealing, colour options, and weather timing for Oshawa driveways.
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 Oshawa. 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.

What Oshawa Homeowners Say About 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.
A. P.
Durham
★★★★★
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.
Whitby
★★★★★
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.
