How Much Does 9 Tons of Recycled Concrete Aggregate Cover?
How much does 9 tons of recycled concrete aggregate cover depends on how deep you spread it. At about 1.3 tons per cubic yard, 9 tons is roughly 6.9 cubic yards. Spread 4 inches deep, that covers about 561 square feet. Every added inch of depth cuts the coverage noticeably.
Volume and tonnage calculator →How the coverage is figured
- Tons to cubic yards: 9 ÷ 1.3 = 6.9 yd³.
- Cubic yards to cubic feet: × 27 = 187 cu ft.
- Divide by depth in feet: at 4 inches (0.333 ft), 187 ÷ 0.333 = 561 sq ft.
Coverage of 9 tons at different depths
| Depth | Square feet covered | Square yards |
|---|---|---|
| 3 in | 748 | 83 |
| 4 in | 561 | 62 |
| 6 in | 374 | 42 |
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. Weight runs about 1.2 to 1.4 tons per cubic yard, so treat the table as a planning range rather than an exact figure.
What 9 tons looks like on site
For delivery, 9 tons is in the range of one full tandem load. Ask the supplier how they will split it. Spread from the pile with a loader, skid steer or wheelbarrow, then rake to depth before compacting if the material calls for it.
- Check depth as you go. Stakes marked at the target depth help keep the spread even.
- Expect some loss. Compaction and uneven ground use more than the flat-math figure. Keep about 10 percent in reserve.
- Ask about moisture. Wet material weighs more, so a ton of it covers less.
To run your own numbers, use the volume and tonnage calculator.
When to choose recycled concrete aggregate
Good uses:
- 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 20x25 area at 3 inches takes about 6.0 tons.
- Weight used here: about 1.3 tons per cubic yard.
Common estimating mistakes
- Forgetting that compaction shrinks loose material. A loose 4-inch spread of a dense-graded stone may finish closer to 3 inches after rolling.
- Skipping drainage. Water sitting under any surface softens the base and leads to ruts and potholes.
- 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.
