How Much Limestone Screenings for a 4x15 Walkway?
How much limestone screenings for a 4x15 walkway: at 3 inches deep you need about 0.56 cubic yards, which is roughly 0.8 tons at 1.4 tons per yard. The walkway covers 60 square feet, so every inch of depth adds about 0.19 yards.
Volume and tonnage calculator →The math for a 4x15 walkway
- Area: 4 × 15 = 60 sq ft.
- Depth in feet: 3 ÷ 12 = 0.250 ft.
- Cubic feet: 60 × 0.250 = 15.0 cu ft.
- Cubic yards: ÷ 27 = 0.56 yd³.
- Tons: × 1.4 = 0.8 tons.
The volume and tonnage calculator does this for any size.
Limestone screenings needed by depth
| Depth | Cubic yards | Tons (approx.) | Tons +10% |
|---|---|---|---|
| 1 in | 0.19 | 0.3 | 0.3 |
| 2 in | 0.37 | 0.5 | 0.6 |
| 3 in | 0.56 | 0.8 | 0.9 |
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. If the yard sells by the cubic yard instead of the ton, use the cubic-yard column directly.
Preparing the walkway
Dig the path a few inches below grade, compact the bottom, add fabric if needed and install edging on both sides so the material stays on the walk. This walkway sees foot traffic, so match the depth to that load rather than to the minimum.
Ordering tips
- Round up. Compaction and uneven ground eat material. Adding about 10 percent is common.
- Delivery size. 0.9 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 about 0.8 tons this job is small enough that bagged material could work; a 0.5 cubic foot bag holds about 1/54 of a yard, so compare the bag count with a bulk minimum.
- Where it drops. Have the truck dump as close to the walkway as firm ground allows.
When to choose limestone screenings
Good uses:
- 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.
Mistakes that throw off the order
- 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.
- Measuring only the main rectangle. Aprons, turnouts and curved edges add real square footage.
- Using inches as if they were feet. Depth has to be divided by 12 before you multiply; skipping that step inflates the order twelvefold.
