How Much Recycled Concrete Aggregate for a 16x12 Shed Base?
How much recycled concrete aggregate for a 16x12 shed base is a quick volume problem. 192 square feet at 4 inches comes to 2.37 cubic yards. Recycled concrete aggregate usually weighs about 1.2 to 1.4 tons per cubic yard, so plan on roughly 3.1 tons.
Volume and tonnage calculator →The math for a 16x12 shed base
- Area: 16 × 12 = 192 sq ft.
- Depth in feet: 4 ÷ 12 = 0.333 ft.
- Cubic feet: 192 × 0.333 = 64.0 cu ft.
- Cubic yards: ÷ 27 = 2.37 yd³.
- Tons: × 1.3 = 3.1 tons.
The volume and tonnage calculator does this for any size.
Recycled concrete aggregate needed by depth
| Depth | Cubic yards | Tons (approx.) | Tons +10% |
|---|---|---|---|
| 3 in | 1.78 | 2.3 | 2.5 |
| 4 in | 2.37 | 3.1 | 3.4 |
| 6 in | 3.56 | 4.6 | 5.1 |
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. If the yard sells by the cubic yard instead of the ton, use the cubic-yard column directly.
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. 3.4 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 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.
Where recycled concrete aggregate fits
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 15x30 area at 2 inches takes about 3.6 tons.
- Weight used here: about 1.3 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.
- Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
- Forgetting that compaction shrinks loose material. A loose 4-inch spread of a dense-graded stone may finish closer to 3 inches after rolling.
- Measuring only the main rectangle. Aprons, turnouts and curved edges add real square footage.
