#57 Gravel vs Compost

#57 Gravel

Crushed stone approximately 3/4 to 1 inch in size. One of the most versatile and commonly used gravel sizes in both residential and commercial construction. #57 stone is the go-to aggregate for drainage, driveways, and concrete production.

Compost

Decomposed organic matter used as a soil amendment to improve soil structure, fertility, and water retention. Quality compost is dark, crumbly, and earthy-smelling. It adds beneficial microorganisms and nutrients that support healthy plant growth and improve poor soils.

#57 Gravel

• ✓ Driveways
• ✓ Drainage
• ✓ Concrete mix
• ✓ Pipe bedding
• ✓ Backfill
• ✓ Parking areas

Compost

• ✓ Soil amendment
• ✓ Garden beds
• ✓ Lawn top-dressing
• ✓ Raised beds
• ✓ Tree and shrub planting
• ✓ Seed starting mix

#57 Gravel

• + Extremely versatile — works for many applications
• + Excellent drainage characteristics
• + Good compaction when combined with fines
• + Widely available nationwide
• + Cost-effective

• − Too coarse for comfortable walking
• − Angular edges
• − Shifts under foot traffic without stabilization
• − Requires a finer top layer for driveways
• − Not decorative

Compost

• + Dramatically improves soil structure and fertility
• + Increases water retention in sandy soils
• + Improves drainage in clay soils
• + Adds beneficial microorganisms
• + Reduces need for chemical fertilizers

• − Quality and composition vary widely between sources
• − Can be odorous when fresh
• − May contain weed seeds if not fully composted
• − Too rich for direct planting — must be mixed with soil
• − Settles significantly after application

#57 Gravel

#57 gravel consists of angular crushed stone pieces ranging from 3/4" to 1" in diameter. Color depends on the quarry source — typically gray, blue-gray, or brown. The stones are angular and irregular, which helps them interlock.

Compost

Fine, crumbly texture when fully decomposed. Dark brown to black color. Should smell earthy, not sour or ammonia-like. Screened compost has been filtered to remove large uncomposted pieces. Mushroom compost is a byproduct of mushroom farming and is particularly nutrient-rich.
