Grey Exposed Aggregate Driveway

Grey exposed aggregate is quietly one of the most practical driveway finishes available — and one of the most underrated visually. The washed surface reveals the pebble and stone aggregate below, creating a texture that's slip-resistant, hides tire marks, and ages without looking worn. In a cool grey or charcoal tone, it reads as clean and deliberate rather than decorative.

The grey palette works because it's flexible. A lighter silver-grey suits coastal and contemporary homes with white or light board-and-batten exteriors. Charcoal aggregate gives a more grounded, urban look that pairs well with dark timber, black window frames, and modern landscaping. The finish has no directional pattern, which means it handles curved driveways and irregular layouts more naturally than stamped concrete — no alignment decisions, no pattern interruptions at the curves.

From a cost standpoint, grey exposed aggregate driveways run $8–14 per sq ft installed — the middle ground between plain broom finish ($6–10) and stamped concrete ($12–20). On a standard two-car driveway (400–500 sq ft), that's $3,200–7,000. Maintenance is straightforward: seal every 2–3 years with a penetrating sealer to protect the aggregate from staining and keep the color depth. The finish holds its character well over time — unlike stamped concrete, there's no color wash that fades unevenly.
