Bank Run Gravel vs Decomposed Granite: Size, Cost, and Which to Use

Bank Run Gravel

Bank run gravel is a naturally occurring mix of sand, gravel, and small stones excavated directly from pits or riverbanks. Unlike crusher run, it is not mechanically crushed or screened, resulting in inconsistent sizing.

Decomposed Granite

Decomposed granite, or DG, is granite that weathered in the ground into a mix of sand, silt, and small chips, then was dug and screened to 1/4 or 3/8 inch minus. It costs $25 to $45 per ton in 2026, weighs 1.3 to 1.5 tons per cubic yard, and compacts into a firm, natural-looking path or patio surface in gold, tan, gray, or rose. It is the standard path material in California, Arizona, Texas, and most of the drought-tolerant West.

Bank Run Gravel

• + Low cost
• + Minimal processing
• + Good general fill material

• − Inconsistent size
• − Poor compaction compared to crusher run
• − Can contain excess sand

Decomposed Granite

• + Natural gold and tan look that fits Western landscapes
• + Compacts into a firm, walkable surface
• + Cheap at $25 to $45 per ton loose
• + Permeable, counts as pervious surface in many codes
• + Easy to install with a plate compactor

• − Loose DG tracks into the house and erodes in rain
• − Stabilizer adds $10 to $30 per ton
• − Needs edging or it spreads
• − Poor in freeze-thaw climates
• − Muddy when saturated

Bank Run Gravel

Unscreened blend ranging from sand up to 2" stones. Color varies by region.

Decomposed Granite

Decomposed granite is a mix of sand-sized particles and small granite chips, usually 1/4 inch minus, sometimes 3/8 inch minus. Colors run gold, tan, buff, gray, brown, and rose depending on the quarry. Gold and tan are the standard California and Arizona look. Sold loose, or stabilized with a binder that is mixed in dry or applied as a liquid.
