How Much Limestone Screenings for a 5x15 Walkway?

How much limestone screenings for a 5x15 walkway: at 3 inches deep you need about 0.69 cubic yards, which is roughly 1.0 tons at 1.4 tons per yard. The walkway covers 75 square feet, so every inch of depth adds about 0.23 yards.

The math for a 5x15 walkway

  1. Area: 5 × 15 = 75 sq ft.
  2. Depth in feet: 3 ÷ 12 = 0.250 ft.
  3. Cubic feet: 75 × 0.250 = 18.8 cu ft.
  4. Cubic yards: ÷ 27 = 0.69 yd³.
  5. Tons: × 1.4 = 1.0 tons.

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 per yard is a planning number; the scale ticket at the yard is the real one.

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. 1.1 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 1.0 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.

Where limestone screenings fits

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 12x24 area at 3 inches takes about 3.7 tons.
  • Weight used here: about 1.4 tons per cubic yard.

Mistakes that throw off the order

  • Skipping drainage. Water sitting under any surface softens the base and leads to ruts and potholes.
  • Forgetting that compaction shrinks loose material. A loose 4-inch spread of a dense-graded stone may finish closer to 3 inches after rolling.
  • Measuring only the main rectangle. Aprons, turnouts and curved edges add real square footage.
  • Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
