How to Lay a Simple Gravel Patio in a Weekend

Start by measuring the area in square feet: multiply length by width. For a 12 ft by 15 ft space you get 180 sq ft. Use stakes and a mason’s line to mark corners, square the layout with a 3-4-5 triangle if needed, and confirm the patio slope is about 1/8 in per foot away from the house to prevent runoff; that is roughly 1% slope or 0.125 in per ft.

Decide on finished surface depth: aim for a minimum compacted base of 3 in of 3/4-in crushed stone and 2–3 in of top decorative gravel, giving a total of 5–6 in. If ground is soft or you expect occasional vehicle loads, increase the base to 4–6 in of compacted crushed stone. Use the formula area (sq ft) x depth (ft) ÷ 27 to convert to cubic yards. Example: 180 sq ft x 0.5 ft ÷ 27 ≈ 3.33 cu yd; order 10% extra, so about 3.7 cu yd.

Gather tools and materials: hand tamper or 100–150 lb plate compactor, shovel, steel rake, wheelbarrow (typical capacity 6 cu ft), landscape fabric (6 oz woven or heavier), 3/4-in crushed stone for base, and 3/8–3/4-in decorative gravel for the top. You will also need edge restraints: steel, plastic, or treated timber. A tape measure, level or laser level, and a 6-ft straight board for screeding complete the kit.

Plan work in two half-days if possible: Day 1 for clearing, excavation, and base installation (4–6 hours for a 180 sq ft area by two people), Day 2 for screeding, compacting, and finishing (3–5 hours). Rent a plate compactor for one day; a typical rental saves many hours of hand tamping and usually takes 4–6 hours of use to complete a 180 sq ft patio.

Order stone by cubic yards and plan delivery: a small dump truck unloads 2–6 cu yd in 10–20 minutes, but spreading takes longer. For a 180 sq ft patio at 6 in total depth you need about 3.33 cu yd (90 cu ft); with a 6 cu ft wheelbarrow that is about 15 wheelbarrow trips (90 ÷ 6 = 15). Allow 1–2 hours for delivery placement and staging.

Call 811 to locate underground utilities at least 72 hours before digging. If you find large roots or unexpected pipes, pause and adjust the layout by 6–12 in to avoid disturbance.

Clear the surface of sod, roots, and debris down to the desired subgrade. For a 180 sq ft patio at 6 in total depth you will remove about 90 cu ft of material (180 x 0.5 ft = 90 cu ft), which is roughly 3.33 cu yd. With a 6 cu ft wheelbarrow plan for about 15 full trips to haul material away or to bring in stone.

Two people can typically excavate to 6 in depth at a steady pace of 18–25 sq ft per hour; expect 3–5 hours of digging for 180 sq ft. Work in 2–3 ft sections, keep the bottom level to your string lines, and check slope every 4–6 ft with a 6-ft level or laser level. If the soil is clayey and holds water, remove an extra 1–2 in of soil and plan to backfill with extra crushed stone—add 0.25–0.5 cu yd for a 180 sq ft area if you remove 2 in more.

Install edging before laying the base stone so the edge restraint sits on firm ground. Position edging so the top of your finished gravel will be 1/2 in to 1 in below adjacent hard surfaces to avoid tripping. Secure edging with spikes every 12–18 in; if using timber, fasten posts every 24–36 in and treat contact points to resist rot. Check the perimeter with a string line to keep the edge straight to within 1/4 in over 8 ft.

Lay landscape fabric across the excavated area with 6–12 in overlaps; anchor with landscape pins every 3–4 ft or every 2 ft along seams. The fabric reduces weed growth and prevents bedding stone from mixing with soil while still allowing drainage. For heavy clay use a woven fabric rated for heavy loads (minimum 6 oz) and run the fabric up the edge restraint by 1–2 in to keep the stone from migrating.

Spread the crushed-stone base in 1–2 lifts. If your target is 3–4 in compacted, spread two lifts of about 2 in loose each, compacting between lifts. Use a plate compactor and make overlapping passes in a grid pattern—typically 4–6 passes per strip and 2–3 passes at staggered angles—until the base deflects minimally. Compact to a firm surface; you should not be able to make an indentation with the heel of your boot more than 1/4 in.

Screed the top gravel: set two screed rails at the finished height and pull a 6-ft straight board across them to level the stone to the desired 2–3 in. Work with two people: one holds the screed board while the other moves gravel forward. Remove the rails slowly and fill any low spots, then make a final pass with the compactor if using angular stone. For pea gravel, limit compaction to light tamping to retain a comfortable walking surface.

Check drainage by running water from a hose for 1–2 minutes in several spots; water should move away from the house at roughly 1/8 in per foot. Clean up edges and add a final 1/2 in to 1 in of gravel where needed to match adjacent levels. Expect minor settling; plan to top up with 0.5–1 in of gravel every 2–3 years depending on use.
