How Much Sand for a 6x100 Walkway?

A 6 by 100 foot walkway is 600 square feet. How much sand for a 6x100 walkway depends on depth: at 3 inches it is about 5.56 cubic yards or 7.5 tons. Suppliers usually sell by the ton, so the tonnage is the number to give them.

The math for a 6x100 walkway

  1. Area: 6 × 100 = 600 sq ft.
  2. Depth in feet: 3 ÷ 12 = 0.250 ft.
  3. Cubic feet: 600 × 0.250 = 150.0 cu ft.
  4. Cubic yards: ÷ 27 = 5.56 yd³.
  5. Tons: × 1.35 = 7.5 tons.

About sand

For paver bedding, concrete sand (coarse, washed) is the usual pick. Mason sand is finer and used in mortar and play areas. 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. Since the walkway carries foot traffic, a little extra depth is cheap insurance.

Ordering tips

  • Round up. Compaction and uneven ground eat material. Adding about 10 percent is common.
  • Delivery size. 8.2 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 this size bulk delivery is usually the practical choice.
  • Where it drops. Have the truck dump as close to the walkway as firm ground allows.

Good and poor uses for sand

Good uses:

  • Paver and flagstone bedding
  • Leveling under above-ground pools (with the right product)
  • Filling joints and backfilling pipe

Think twice for:

  • Driveway bases, since sand shifts under load
  • Steep areas exposed to runoff
  • Thick layers under pavers, which settle unevenly

Quick reference numbers

  • Per inch over 100 sq ft: about 0.42 tons of sand (0.31 cubic yards).
  • Per inch over 1,000 sq ft: about 4.2 tons.
  • Another size for comparison: a 15x30 area at 4 inches takes about 7.5 tons.
  • Weight used here: about 1.35 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.
  • Assuming every supplier uses the same weight. Two yards selling the same product name can quote different tons per yard.
  • Mixing up cubic yards and tons. Yards are volume, tons are weight; convert with the product’s weight per yard.
  • Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
