Charcoal exposed aggregate patio uses dark basalt or black river pebble to create a surface that is simultaneously tactile and visually bold. Where white exposed aggregate scatters light and reads as bright, charcoal aggregate absorbs it - the surface tone shifts as the angle of light changes across the day, and after rain the wet pebbles develop a deep gloss that transforms the backyard at close range.

The material logic suits contemporary homes where a dark exterior palette is already in play. Charcoal aggregate echoes dark metal cladding, black window frames, and charcoal board-and-batten siding without requiring a colour match. Against a lighter home exterior - white, cream, or soft grey - the dark aggregate creates the kind of foreground contrast that photographers and designers favour: the patio grounds the space and makes the home read stronger above it.

From a practical standpoint, dark aggregate hides surface staining and debris between cleanings better than lighter finishes. The exposed surface provides excellent wet-weather slip resistance - the individual pebble texture prevents the smooth-surface hydroplaning that can occur on plain polished concrete. Cost runs $10-16 per sq ft installed. No sealing required, though a penetrating sealer applied every 3-5 years can deepen the stone colour if the visual intensity is valued.
