How Much Does 27 Tons of Limestone Screenings Cover?
How much does 27 tons of limestone screenings cover depends on how deep you spread it. At about 1.4 tons per cubic yard, 27 tons is roughly 19.3 cubic yards. Spread 2 inches deep, that covers about 3,124 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: 27 ÷ 1.4 = 19.3 yd³.
- Cubic yards to cubic feet: × 27 = 521 cu ft.
- Divide by depth in feet: at 2 inches (0.167 ft), 521 ÷ 0.167 = 3,124 sq ft.
Coverage of 27 tons at different depths
| Depth | Square feet covered | Square yards |
|---|---|---|
| 1 in | 6,249 | 694 |
| 2 in | 3,124 | 347 |
| 3 in | 2,083 | 231 |
About limestone screenings
Limestone screenings are the fine dust and chips left after crushing limestone. They pack very tight, which makes them a common setting bed for pavers and flagstone and a surface for paths. 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 27 tons looks like on site
27 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.
Good and poor uses for limestone screenings
Best suited to:
- Paver and flagstone setting beds
- Firm walking paths
- Top-dressing a compacted stone base
Think twice 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 3 inches takes about 1.7 tons.
- Weight used here: about 1.4 tons per cubic yard.
Where estimates go wrong
- Assuming every supplier uses the same weight. Two yards selling the same product name can quote different tons per yard.
- Skipping drainage. Water sitting under any surface softens the base and leads to ruts and potholes.
- Using inches as if they were feet. Depth has to be divided by 12 before you multiply; skipping that step inflates the order twelvefold.
- Measuring only the main rectangle. Aprons, turnouts and curved edges add real square footage.
