Stone-Textured Patios in Oshawa Built for Wet Grip
Exposed aggregate concrete delivers the look of natural stone underfoot with the strength and low maintenance of a poured slab. We wash back the surface to reveal embedded stones, creating a patio that grips wet feet, resists visible wear, and needs less frequent sealing than decorative alternatives. Every project begins with a free site estimate.
How Exposed Aggregate Concrete Works for Oshawa Yards
The finished patio is a standard concrete slab poured over compacted granular base, sloped to shed water away from the house. What sets exposed aggregate apart is the surface treatment: after the concrete sets to the right stage, we wash back the top layer to expose the stones embedded in the mix. This reveals natural texture, creates mechanical grip, and gives a decorative appearance without the pattern-stamping process.
The aggregate itself is selected for size, colour, and character. Smaller pea gravel produces a fine, uniform texture. Larger stones create a bolder, more dramatic look. The base concrete can be tinted to shift the overall tone. Once cured, the patio is sealed to lock in colour, protect the stone-concrete interface, and extend the life of the slab.
Compared to stamped patio finishes, exposed aggregate requires less frequent resealing. Compared to plain concrete, it offers visual interest and superior wet traction. It sits in the middle ground for both cost and maintenance, making it a practical choice for outdoor living spaces that see regular use.

Pouring an Exposed Aggregate Patio Step by Step
Select stone and colour
We review aggregate options with you, showing samples of different stone sizes and base concrete tints. You choose the look and texture depth you want, and we confirm the final appearance in natural daylight.
Prepare and form the site
The patio area is excavated to depth, a compacted granular base is laid, and wooden or metal forms are set to establish the finished grade and slope. Edge details and transitions to existing structures are framed in.
Place and finish concrete
Air-entrained concrete is delivered and placed into the forms, screeded level, and allowed to set to the precise stage where the surface paste will wash away cleanly without dislodging the embedded stones.
Wash and seal the surface
Once the concrete has cured sufficiently, the surface is washed to expose the aggregate, then sealed with a protective coating that enhances colour, locks in the stone, and guards against water penetration and freeze-thaw damage.
Making the choice
Exposed Aggregate vs Other Patio Options
Exposed aggregate sits between plain and stamped in both appearance and upkeep. The natural stone texture is visually distinctive without requiring the labour-intensive stamping process. Sealing is needed every three to four years, less frequently than stamped surfaces but more often than plain concrete. The cost is typically lower than stamped because no pattern tooling is involved.
If an existing patio is sound but tired, patio resurfacing can refresh it with a new finish. Exposed aggregate also integrates well with other hardscape elements like walkways, steps, and retaining walls, creating a cohesive outdoor environment.
Texture, grip, sealing and how exposed aggregate compares for Oshawa patios.
No, the opposite. The stone texture gives traction wet, which is why it is popular for patios that get pool splash, rain or morning dew. Much grippier than a smooth or even broom-finish patio.
Typically every three to four years in Oshawa, slightly less often than stamped patios but more often than plain concrete. The seal protects the spaces between the stones from water getting in.
Not when the patio is poured and sealed properly. The aggregate is embedded in the concrete matrix, not laid on top, so the stones are mechanically locked in. Sealing protects the matrix from freeze-thaw working stones loose.
Yes. The base concrete can be integrally coloured under the exposed surface, and the aggregate choice shifts the tone too. We bring sample boards so you can see combinations in daylight before the pour.
Exposed aggregate usually costs less than stamped concrete because the stamp tooling and labour are not part of the job. The trade-off is a different decorative style, texture from stone rather than pattern from a stamp.
