Gravel & Aggregate Materials Directory
Compare bulk densities, compaction ratings, grain textures, and price baselines across all 14 standard gravel, crushed stone, and base rock aggregates.
Pea Gravel (3/8" Smooth)
Smooth, rounded stones naturally weathered by water. Ideal for barefoot walkways, patios, playground surrounds, and decorative garden beds.
#57 Crushed Stone (3/4" Angular)
The workhorse of aggregate. Angular, clean-washed 3/4-inch stones that lock together tightly. Perfect for driveway top coats, French drains, and concrete mixes.
Crusher Run / Dense Grade / QP
A blend of crushed stone (up to 3/4") and fine stone dust. Compacts into a solid, nearly impermeable base that resists rutting and washouts.
River Rock (1" - 3" Rounded)
Smooth, colorful river stones for upscale decorative landscape beds, dry creek beds, erosion control on gentle slopes, and water features.
Crushed Limestone Gravel
Widely available, durable crushed limestone with sharp fractured faces. Provides high traction and compacts solidly under vehicle traffic.
Crushed Granite Gravel
Extremely hard and long-lasting igneous rock with distinctive salt-and-pepper or pink/grey coloration. Does not break down over decades of use.
Decomposed Granite (DG with Fines)
Naturally weathered granitic rock with fine particles. Creates a firm, rustic, natural-looking surface popular for Southwestern landscaping and park pathways.
#8 Stone (3/8" Clean Chip)
Small, uniform 3/8" angular crushed stone chips with fines screened out. Great for leveling pavers, tar-and-chip driveways, and top dressing walkways.
Drainage Rock (1.5" - 2.5" Washed)
Large, clean open-graded stone that leaves large void spaces for high-velocity water movement. Does not clog with silt.
Lava Rock / Scoria (Volcanic)
Porous, ultra-lightweight volcanic stone in red or black. Excellent insulator for fire pits and decorative beds without adding heavy ground weight.
Road Base #411 (1" Down to Dust)
Heavy aggregate engineered to interlock into a hardpan subbase beneath asphalt, concrete, or heavy gravel driveways.
