How Much Does 45 Tons of Limestone Screenings Cover?
How much does 45 tons of limestone screenings cover depends on how deep you spread it. At about 1.4 tons per cubic yard, 45 tons is roughly 32.1 cubic yards. Spread 2 inches deep, that covers about 5,207 square feet. Go thinner and it covers more; go deeper and it covers less.
Volume and tonnage calculator →How the coverage is figured
- Tons to cubic yards: 45 ÷ 1.4 = 32.1 yd³.
- Cubic yards to cubic feet: × 27 = 868 cu ft.
- Divide by depth in feet: at 2 inches (0.167 ft), 868 ÷ 0.167 = 5,207 sq ft.
Coverage of 45 tons at different depths
| Depth | Square feet covered | Square yards |
|---|---|---|
| 1 in | 10,414 | 1,157 |
| 2 in | 5,207 | 579 |
| 3 in | 3,471 | 386 |
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.
What 45 tons looks like on site
For delivery, 45 tons means multiple trips or a larger truck. 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.
Good and poor uses for limestone screenings
Best suited to:
- Paver and flagstone setting beds
- Firm walking paths
- Top-dressing a compacted stone base
Less suited to:
- 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 14x28 area at 3 inches takes about 5.1 tons.
- Weight used here: about 1.4 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.
- Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
- 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.
