How Much Recycled Concrete Aggregate for a 10x10 Shed Base?

A 10 by 10 foot shed base is 100 square feet. How much recycled concrete aggregate for a 10x10 shed base depends on depth: at 4 inches it is about 1.23 cubic yards or 1.6 tons. Suppliers usually sell by the ton, so the tonnage is the number to give them.

The math for a 10x10 shed base

  1. Area: 10 × 10 = 100 sq ft.
  2. Depth in feet: 4 ÷ 12 = 0.333 ft.
  3. Cubic feet: 100 × 0.333 = 33.3 cu ft.
  4. Cubic yards: ÷ 27 = 1.23 yd³.
  5. Tons: × 1.3 = 1.6 tons.

About recycled concrete aggregate

Ask whether the recycled concrete has been screened for rebar and debris. Fresh-crushed concrete can also be alkaline, so keep it away from sensitive plantings and streams. Weight per yard is a planning number; the scale ticket at the yard is the real one.

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. This shed base sees a shed floor frame, so match the depth to that load rather than to the minimum.

Ordering tips

  • Round up. Compaction and uneven ground eat material. Adding about 10 percent is common.
  • Delivery size. 1.8 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 recycled concrete aggregate

Works well for:

  • Driveway and pad bases
  • Temporary construction entrances
  • Fill under slabs when compacted in lifts

Less suited to:

  • Near ponds, streams or sensitive plants, since fresh crush can raise pH
  • Decorative top layers
  • Drainage layers, unless the product is clean and screened

Quick reference numbers

  • Per inch over 100 sq ft: about 0.40 tons of recycled concrete aggregate (0.31 cubic yards).
  • Per inch over 1,000 sq ft: about 4.0 tons.
  • Another size for comparison: a 20x25 area at 2 inches takes about 4.0 tons.
  • Weight used here: about 1.3 tons per cubic yard.

Where estimates go wrong

  • Skipping drainage. Water sitting under any surface softens the base and leads to ruts and potholes.
  • Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
  • Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
  • Measuring only the main rectangle. Aprons, turnouts and curved edges add real square footage.
