How Much Road Base for a 10x10 Shed Base?
A 10 by 10 foot shed base is 100 square feet. How much road base for a 10x10 shed base depends on depth: at 4 inches it is about 1.23 cubic yards or 1.9 tons. Suppliers usually sell by the ton, so the tonnage is the number to give them.
Volume and tonnage calculator →The math for a 10x10 shed base
- Area: 10 × 10 = 100 sq ft.
- Depth in feet: 4 ÷ 12 = 0.333 ft.
- Cubic feet: 100 × 0.333 = 33.3 cu ft.
- Cubic yards: ÷ 27 = 1.23 yd³.
- Tons: × 1.5 = 1.9 tons.
The volume and tonnage calculator does this for any size.
Road base needed by depth
| Depth | Cubic yards | Tons (approx.) | Tons +10% |
|---|---|---|---|
| 4 in | 1.23 | 1.9 | 2.0 |
| 6 in | 1.85 | 2.8 | 3.1 |
| 8 in | 2.47 | 3.7 | 4.1 |
About road base
Road base (also called base rock, ABC, or Class 2 base in different states) is a graded mix of stone and fines made to compact into a load-bearing layer. Ask your supplier for their own tons-per-yard figure, since stone source and moisture shift it.
Preparing the shed base
Level the footprint, extend the stone a foot or so beyond the shed walls for drip and drainage, and compact in lifts. A timber or block border holds the pad shape. Since the shed base carries a shed floor frame, a little extra depth is cheap insurance.
Ordering tips
- Round up. Compaction and uneven ground eat material. Adding about 10 percent is common.
- Delivery size. 2.0 tons fits in a single typical dump truck load; small loads may carry a delivery fee. See how many tons of gravel in a dump truck.
- Bulk vs bags. At this size bulk delivery is usually the practical choice.
- Where it drops. Have the truck dump as close to the shed base as firm ground allows.
When to choose road base
Best suited to:
- Base under asphalt and concrete
- Gravel roads and drives
- Equipment and shed pads
Poor fit for:
- Drainage layers
- Decorative surfaces
- Surfaces that will stay uncompacted
Quick reference numbers
- Per inch over 100 sq ft: about 0.46 tons of road base (0.31 cubic yards).
- Per inch over 1,000 sq ft: about 4.6 tons.
- Another size for comparison: a 15x30 area at 4 inches takes about 8.3 tons.
- Weight used here: about 1.5 tons per cubic yard.
Common estimating mistakes
- Using inches as if they were feet. Depth has to be divided by 12 before you multiply; skipping that step inflates the order twelvefold.
- Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
- Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
- Skipping drainage. Water sitting under any surface softens the base and leads to ruts and potholes.
