How Much Does 30 Tons of Limestone Screenings Cover?
How much does 30 tons of limestone screenings cover depends on how deep you spread it. At about 1.4 tons per cubic yard, 30 tons is roughly 21.4 cubic yards. Spread 2 inches deep, that covers about 3,471 square feet. Halve the depth and you roughly double the area.
Volume and tonnage calculator →How the coverage is figured
- Tons to cubic yards: 30 ÷ 1.4 = 21.4 yd³.
- Cubic yards to cubic feet: × 27 = 579 cu ft.
- Divide by depth in feet: at 2 inches (0.167 ft), 579 ÷ 0.167 = 3,471 sq ft.
Coverage of 30 tons at different depths
| Depth | Square feet covered | Square yards |
|---|---|---|
| 1 in | 6,943 | 771 |
| 2 in | 3,471 | 386 |
| 3 in | 2,314 | 257 |
About limestone screenings
Screenings hold moisture and can crust over. Use them in thin layers over a compacted stone base instead of as a thick layer on their own. Weight runs about 1.3 to 1.5 tons per cubic yard, so treat the table as a planning range rather than an exact figure.
Planning around 30 tons
30 tons will usually take two or more truck loads, though legal limits vary by truck and state. 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 limestone screenings
Best suited to:
- Paver and flagstone setting beds
- Firm walking paths
- Top-dressing a compacted stone base
Poor fit for:
- Deep layers on their own
- Low spots that collect water
- Under heavy vehicle traffic without a base
Quick reference numbers
- Per inch over 100 sq ft: about 0.43 tons of limestone screenings (0.31 cubic yards).
- Per inch over 1,000 sq ft: about 4.3 tons.
- Another size for comparison: a 8x16 area at 4 inches takes about 2.2 tons.
- Weight used here: about 1.4 tons per cubic yard.
Where estimates go wrong
- Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
- Assuming every supplier uses the same weight. Two yards selling the same product name can quote different tons per yard.
- Measuring only the main rectangle. Aprons, turnouts and curved edges add real square footage.
- Forgetting that compaction shrinks loose material. A loose 4-inch spread of a dense-graded stone may finish closer to 3 inches after rolling.
