Exposed Aggregate Concrete With Natural Grip
Exposed aggregate is concrete at its most honest: real stone, revealed. Instead of hiding the aggregate inside the slab, we wash away the surface paste to expose the pebbles beneath, leaving a permanent, natural texture that looks like a riverbed and grips like sandpaper. It never looks dated because it is not imitating anything.
We pour exposed aggregate across Vaughan and the GTA for driveways, walkways, patios, and pool decks. The stone is part of the slab, not applied to it, so the finish cannot peel, flake, or wear off. With basic care it looks as good in year twenty as year two.
Stone You Can See and Feel
The beauty of exposed aggregate is that no two pours are identical. The stone blend, river-washed pebbles, crushed granite, or decorative mixes, gives each surface its own character. Colours range from warm earth tones to cool greys depending on the aggregate source, and the texture catches light in a way flat concrete never does.
It is also one of the most practical finishes available. The exposed stone provides outstanding wet traction, making it a natural choice for pool decks, sloped walkways, and driveways. It hides dust, pollen, and winter wear better than any smooth finish, which is why it stays handsome with minimal effort.
The Wash Process
Exposed aggregate is all about timing and touch. We pour the concrete with the chosen stone blended through the mix, screed and float it as normal, then apply a surface retarder that slows the set of just the top skin. Hours later, we wash that skin away with water and soft brushing, revealing the stone just beneath.
The wash depth is the craft. Too shallow and the stone barely shows; too deep and stones loosen. We expose to a consistent, attractive depth across the whole slab, then let it cure before sealing. It is skilled work that rewards an experienced crew, and punishes a rushed one.
Where It Shines
Driveways love exposed aggregate: the texture shrugs off tire wear and the stone hides the grime that settles into broom finishes. Walkways gain sure footing in rain and snowmelt. Around pools it is arguably the ideal finish, grippy when wet and cool in light stone blends.
It also pairs beautifully as an accent. An exposed aggregate border around a broom-finished patio, or an exposed walk leading to a stamped entry, gives you designer detail without designer pricing. We will show you aggregate samples during the estimate so you choose stone you have actually seen.
Care and Longevity
Sealer locks everything in. It deepens the stone colours, prevents water intrusion, and makes the surface easier to clean. Reseal every few years and the finish stays rich; skip it and the stone slowly dulls, though the texture remains.
Cleaning is simple: hose it down, and pressure wash gently if needed, keeping the nozzle moving so you do not erode the paste between stones. Because the wearing surface is stone itself, exposed aggregate is among the longest-lived decorative finishes we offer.
Common questions
What kinds of stone can be exposed?
Most commonly river-washed pebbles and crushed granite in various colour blends. We show you actual aggregate samples during the estimate so you pick stone you have seen with your own eyes.
Is exposed aggregate comfortable to walk on barefoot?
Yes, with a standard exposure depth the surface feels pleasantly textured, not sharp. Around pools it is one of the most comfortable and safest finishes available.
Will the stones pop out over time?
Not when the wash depth is right. Stones are embedded in the slab, not glued on. Over decades a few surface pebbles may loosen, but the finish as a whole stays intact.
Exposed aggregate or stamped concrete, which lasts longer?
Both last decades when built right. Exposed aggregate has an edge in harsh conditions because the wearing surface is stone itself, and it needs resealing less often to look good. Stamped offers more pattern variety. We will help you weigh it for your project.
