A scored grid concrete patio with gravel-filled channels brings a graphic, architectural quality to an outdoor surface without requiring stamping or specialty finishes. The grid is cut into the cured concrete in a regular square or rectangular pattern - typically 18x18 inch or 24x24 inch modules - with recessed channels 1-2 inches wide. White pea gravel, black river rock, or charcoal aggregate fills the channels, creating a strong visual contrast between the smooth concrete field and the textured inlay.

The visual effect is closest to large-format tile - it reads as a premium, designed surface at first glance. The grid provides a sense of order and rhythm that makes even a large patio feel considered and intentional. Pea gravel channels also provide a natural drainage pathway across the surface, reducing ponding after rain and improving the patio's usability in wet conditions.

Color choice in the gravel inlay defines the mood. White pea gravel against light grey concrete is crisp and contemporary - the go-to for homes with white or light grey exteriors. Black river rock against medium grey creates a higher-contrast, more dramatic effect suited to darker or more modern exteriors. Charcoal aggregate against buff concrete reads warmer and suits transitional and craftsman-adjacent styles.

Scored concrete with gravel inlay costs $10-16 per sq ft installed - meaningfully less than stamped patterns because the work involves cutting rather than stamping, with no colour release required. Resealing the concrete portion every 2-3 years maintains the surface finish. PourCanvas can show you how a scored grid layout would look on your specific patio before you commit.
