Estimate gravel needed for driveways, patios, and landscaping projects. Includes depth recommendations.
Depth Guidelines: Driveways need 4-6 inches of gravel over a compacted base. Walkways and patios can use 2-3 inches. Always add 10% extra for compaction and spillage.
Base Preparation: For driveways, excavate 8-12 inches and lay geotextile fabric. Add 4-6 inches of crushed stone base, then 2-3 inches of top gravel.
Delivery: Most gravel companies have a minimum order (usually 10-20 tons). A standard dump truck holds 10-16 tons. Order a bit extra — leftover gravel is useful for repairs.
Types of Gravel: #57 crushed stone (3/4″) is best for driveways. Pea gravel (1/4″-1/2″) is better for walkways and drainage. Check local availability and prices.
Driveways need 4-6 inches of gravel over a compacted base. For heavy vehicles, use 8-12 inches total (base + top layer). Always add 10% extra for compaction.
It depends on gravel type: Crushed stone = 1.35 tons/cu yd, Pea gravel = 1.4 tons/cu yd, River rock = 1.25 tons/cu yd, Decomposed granite = 1.5 tons/cu yd.
#57 crushed stone (3/4″) is best for driveways. It locks together well and drains properly. Top with 2-3 inches of smaller gravel (#57 or #78) for a smooth surface.
Use the formula: π × radius² × depth. For a 20-ft diameter circle: 3.14 × 10² × 0.33 ft (4″ depth) = 103.6 cu ft = 3.84 cu yd. Add 10% = 4.2 cu yd.
Yes, for driveways and walkways. Geotextile fabric prevents weeds, stops gravel sinking into soil, and improves drainage. Cost: $20-40 per roll (covers ~300 sq ft).
