How Much Material for a 10x10 Shed Pad? (2026 Full List)

Anatomy of a 10×10 shed pad

A 10×10 shed pad is 100 sq ft, and the standard build is a 4-in crushed-stone base under a 4-in slab. Each layer takes:

• Crushed-stone base — 4 in ≈ 33.3 cu ft; order 1.4–1.5 cu yd.
• Concrete slab — 4 in ≈ 33.3 cu ft; order 1.5 cu yd ready-mix or 56 × 80-lb bags.
• Forms — 2×4s around all four sides (40 linear ft) plus stakes.

Concrete: 33.3 cu ft (1.5 cu yd, or 56 bags)

Volume is area × depth: 100 sq ft × (4 ÷ 12) = 33.3 cu ft, and 33.3 ÷ 27 ≈ 1.23 cu yd. Order 1.5 cu yd of ready-mix to cover leveling waste and truck rounding; in bags (80-lb ≈ 0.60 cu ft):

4 in is the standard shed-pad thickness; the bag route means 56 × 80-lb bags ≈ 4,480 lb — practical only for small pads or repairs. Double-check any slab in the concrete calculator.

Gravel base: order 1.4–1.5 cu yd

The base is the same footprint at the same depth: ≈ 33.3 cu ft = 1.23 cu yd once compacted. Crushed stone is sold loose and settles 10–15%, so 1.23 × 1.10–1.15 ≈ 1.35–1.42 — round the order up to 1.4–1.5 cu yd. Use angular 3/4-in crushed stone; the gravel calculator converts a weight quote to yards.

Forms: five 8-ft 2×4s, eight stakes, and nails

Forms run all four sides: 10 × 4 = 40 linear ft, so five 8-ft 2×4s (pressure-treated lasts longest in ground contact) cover the perimeter exactly. Drive about 8 stakes — every 5 ft plus corners — against the outside of the boards, set them edge-up at slab depth, and pin each stake with 2-in galvanized nails or deck screws.

Ready-mix truck or bagged concrete?

For a 10×10 pad, ready-mix wins: one 1.5 cu yd delivery pours the whole slab in a morning; bags mean batching 4,480 lb over a full day, with cold joints if the pour stalls.

Pick bags only when a truck can't reach the site or the pour is split into sections; rent a mixer and work wet edge to wet edge so the slab cures as one piece.

Shed pad tips that save you a re-pour

• Compact the subgrade first — loose dirt settles and cracks the slab. Skim the sod, level the soil, and tamp it before the gravel goes in.
• Slope for drainage — pitch it about 1/4 in per ft away from the shed door so water never ponds under the floor.
• Compact the stone before pouring — the base must be a full 4 in deep after compaction; that's why you ordered the extra 10–15%.
• Moist-cure the slab — keep it damp or covered 5–7 days so it cures strong instead of cracking.
