Exemple de Calcul Étape par Étape

Scénario: Installing a 10 ft × 20 ft crushed stone patio base with 3 inches depth and 10% compaction allowance.

Area: 20 ft × 10 ft = 200 sq ft.

Depth in Feet: 3 in ÷ 12 = 0.25 ft.

Volume: 200 × 0.25 = 50 cu ft + 10% compaction = 55 cu ft.

Cubic Yards: 55 ÷ 27 = 2.04 cubic yards.

Convert to Tons: 2.04 cu yds × 1.4 tons/yd³ = 2.85 tons.

Result: Order 2.85 tons (or ~3 cubic yards) of crushed stone.

Gravel Weight & Volume Formula

Total Tons = (Length [ft] × Width [ft] × Depth [in ÷ 12]) ÷ 27 × (1 + Buffer) × Density [tons/yd³]

Area is multiplied by layer depth in feet to get volume in cubic feet. Dividing by 27 gives cubic yards. Multiplying cubic yards by the stone density factor (~1.4 tons per yard) produces the total tonnage to purchase.

Variables de la Formule

Volume — Cubic yards of loose aggregate before compaction

Density — 1.4 tons/yd³ for crushed limestone/granite; 1.3 tons/yd³ for pea gravel

Hypothèses de Calcul

Crushed stone base compacts by roughly 10% to 15% when tamped or rolled.
Gravel suppliers typically sell bulk material by the ton or by the cubic yard.

Trade FAQ

Foire Aux Questions

Questions fréquentes sur les projets de rénovationCalculateur de Gravier

How deep should driveway gravel be?

A new gravel driveway needs a total depth of 8 to 12 inches composed in layers: a 4–6 inch sub-base of coarse crushed stone (#3 or #4), followed by a 4-inch layer of #57 stone, topped with 2 inches of dense crusher run.

How many square feet does a ton of gravel cover?

One ton of gravel covers approximately 100 square feet at 2 inches deep, or about 50 square feet at 4 inches deep.
