How Much Recycled Concrete Aggregate for a 14x20 Shed Base?
How much recycled concrete aggregate for a 14x20 shed base is a quick volume problem. 280 square feet at 4 inches comes to 3.46 cubic yards. Recycled concrete aggregate usually weighs about 1.2 to 1.4 tons per cubic yard, so plan on roughly 4.5 tons.
Volume and tonnage calculator →The math for a 14x20 shed base
- Area: 14 × 20 = 280 sq ft.
- Depth in feet: 4 ÷ 12 = 0.333 ft.
- Cubic feet: 280 × 0.333 = 93.3 cu ft.
- Cubic yards: ÷ 27 = 3.46 yd³.
- Tons: × 1.3 = 4.5 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 | 2.59 | 3.4 | 3.7 |
| 4 in | 3.46 | 4.5 | 4.9 |
| 6 in | 5.19 | 6.7 | 7.4 |
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. 4.9 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
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 10x20 area at 4 inches takes about 3.2 tons.
- Weight used here: about 1.3 tons per cubic yard.
Mistakes that throw off the order
- Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
- Skipping drainage. Water sitting under any surface softens the base and leads to ruts and potholes.
- Mixing up cubic yards and tons. Yards are volume, tons are weight; convert with the product’s weight 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.
