Decomposed Granite vs Rip Rap

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.

Rip Rap

Large, heavy, angular stones ranging from 6 to 24+ inches used primarily for erosion control. Rip rap protects shorelines, stream banks, bridge abutments, and steep slopes from water erosion. The heavy weight and interlocking shape resist displacement by flowing water and wave action.

Decomposed Granite

• ✓ Patios
• ✓ Pathways
• ✓ Driveways
• ✓ Xeriscaping
• ✓ Ground cover
• ✓ Bocce courts

Rip Rap

• ✓ Shoreline protection
• ✓ Stream bank stabilization
• ✓ Bridge abutments
• ✓ Steep slope stabilization
• ✓ Culvert outlets
• ✓ Retaining wall faces

Decomposed Granite

• + Compacts into a firm walking surface
• + 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

Rip Rap

• + Extremely effective at preventing water erosion
• + Heavy weight resists displacement by water
• + Long-lasting — lasts decades with no maintenance
• + Angular shape interlocks for stability
• + Natural appearance blends with waterside environments

• − Very heavy — requires heavy equipment to place
• − Expensive for large projects
• − Not suitable for foot traffic
• − Requires engineering design for major installations
• − Limited decorative appeal

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.

Rip Rap

Large angular stones typically 6-24 inches in diameter, though some applications use stones up to 36 inches or larger. Weight ranges from 25 to 500+ pounds per stone. Colors vary by source quarry — typically gray, blue-gray, tan, or brown. Sold by the ton rather than by the yard.
