How Much Recycled Concrete Aggregate for a 10x8 Shed Base?

A 10 by 8 foot shed base is 80 square feet. How much recycled concrete aggregate for a 10x8 shed base depends on depth: at 4 inches it is about 0.99 cubic yards or 1.3 tons. Suppliers usually sell by the ton, so the tonnage is the number to give them.

The math for a 10x8 shed base

Area: 10 × 8 = 80 sq ft.
Depth in feet: 4 ÷ 12 = 0.333 ft.
Cubic feet: 80 × 0.333 = 26.7 cu ft.
Cubic yards: ÷ 27 = 0.99 yd³.
Tons: × 1.3 = 1.3 tons.

The volume and tonnage calculator does this for any size.

About recycled concrete aggregate

Recycled concrete aggregate is crushed old concrete. It compacts well and often costs less than virgin stone, which makes it a common driveway and pad base. 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. 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. 1.4 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 1.3 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

Think twice 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 3 inches takes about 1.5 tons.
Weight used here: about 1.3 tons per cubic yard.

Mistakes that throw off the order

Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
Mixing up cubic yards and tons. Yards are volume, tons are weight; convert with the product’s weight per yard.
Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
Forgetting that compaction shrinks loose material. A loose 4-inch spread of a dense-graded stone may finish closer to 3 inches after rolling.
