Decomposed Granite vs River Rock

Decomposed Granite

Granite that has weathered to the point of breaking into small pieces and fine particles. Creates a natural, rustic look that blends beautifully with desert and Mediterranean landscapes. When compacted, it forms a firm yet permeable surface.

River Rock

Naturally rounded stones smoothed by water erosion. Available in sizes from 1 to 5+ inches. River rock adds a polished, natural look to any landscape and is prized for its smooth texture and visual appeal.

• + Natural, rustic appearance
• + Permeable — allows water infiltration
• + Low cost
• + Ideal for drought-tolerant landscaping

• − Can get muddy in heavy rain
• − Tracked indoors on shoes
• − Decomposes further over time and needs replenishing
• − Limited color options
• − Not suitable for high-traffic vehicle areas

River Rock

• + Beautiful, natural appearance
• + Extremely durable and long-lasting
• + Heavy enough to resist displacement
• + No sharp edges
• + Low maintenance

• − More expensive than crushed stone
• − Heavy and difficult to move
• − Not suitable for walking surfaces
• − Cannot be compacted
• − Limited use for structural applications

Decomposed Granite

Decomposed granite is a mix of fine particles and small chunks, typically 1/4" and smaller. Colors include gold, tan, brown, gray, and reddish-brown depending on the granite source. Stabilized DG (with resin binder) creates an even firmer surface.

River Rock

River rock comes in a wide range of sizes: small (1"–2"), medium (2"–3"), large (3"–5"), and boulders (5"+). Natural colors include gray, brown, tan, white, black, and multi-colored blends. Mexican beach pebbles offer polished black and gray options.
