How Much Recycled Concrete Aggregate for a 10x14 Shed Base?

How much recycled concrete aggregate for a 10x14 shed base: at 4 inches deep you need about 1.73 cubic yards, which is roughly 2.2 tons at 1.3 tons per yard. The shed base covers 140 square feet, so every inch of depth adds about 0.43 yards.

The math for a 10x14 shed base

  1. Area: 10 × 14 = 140 sq ft.
  2. Depth in feet: 4 ÷ 12 = 0.333 ft.
  3. Cubic feet: 140 × 0.333 = 46.7 cu ft.
  4. Cubic yards: ÷ 27 = 1.73 yd³.
  5. Tons: × 1.3 = 2.2 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. 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. For a shed floor frame, the depths in the table above are a reasonable starting range.

Ordering tips

  • Round up. Compaction and uneven ground eat material. Adding about 10 percent is common.
  • Delivery size. 2.5 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.

Good and poor uses for recycled concrete aggregate

Works well for:

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

Poor fit for:

  • 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 15x30 area at 3 inches takes about 5.4 tons.
  • Weight used here: about 1.3 tons per cubic yard.

Where estimates go wrong

  • Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
  • Mixing up cubic yards and tons. Yards are volume, tons are weight; convert with the product’s weight per yard.
  • Assuming every supplier uses the same weight. Two yards selling the same product name can quote different tons per yard.
  • Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
