How Much Recycled Concrete Aggregate for a 8x8 Shed Base?

How much recycled concrete aggregate for a 8x8 shed base: at 4 inches deep you need about 0.79 cubic yards, which is roughly 1.0 tons at 1.3 tons per yard. The shed base covers 64 square feet, so every inch of depth adds about 0.20 yards.

The math for a 8x8 shed base

Area: 8 × 8 = 64 sq ft.
Depth in feet: 4 ÷ 12 = 0.333 ft.
Cubic feet: 64 × 0.333 = 21.3 cu ft.
Cubic yards: ÷ 27 = 0.79 yd³.
Tons: × 1.3 = 1.0 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. 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. 1.1 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 about 1.0 tons this job is small enough that bagged material could work; a 0.5 cubic foot bag holds about 1/54 of a yard, so compare the bag count with a bulk minimum.
Where it drops. Have the truck dump as close to the shed base as firm ground allows.

When to choose recycled concrete aggregate

Good uses:

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 8x16 area at 2 inches takes about 1.0 tons.
Weight used here: about 1.3 tons per cubic yard.

Common estimating mistakes

Skipping drainage. Water sitting under any surface softens the base and leads to ruts and potholes.
Measuring only the main rectangle. Aprons, turnouts and curved edges add real square footage.
Assuming every supplier uses the same weight. Two yards selling the same product name can quote different tons per yard.
Using inches as if they were feet. Depth has to be divided by 12 before you multiply; skipping that step inflates the order twelvefold.
