A gravel driveway is one of the cheapest driveways you can build, and with a little planning it lasts for years. Angi puts the average project at $1,800. Gravel driveways typically last 10 to 20 years with good maintenance (Angi).
Most gravel driveways fail for the same few reasons: the base is too thin, the soil was never prepared, or water sits on the surface. This guide walks through each step of building, laying and installing a gravel driveway the right way.
Quick overview of the steps:
- Plan the layout and check local rules
- Call 811 before you dig
- Remove grass and topsoil
- Grade and compact the subgrade
- Lay geotextile fabric
- Build the base layer
- Add the top layer
- Shape a crown for drainage
- Finish the edges and drainage
Before you start, size the job with the gravel driveway calculator. It gives cubic yards, tons and cost for each layer.
Step 1: Plan the layout
Mark the route of the driveway with stakes and twine from the street to the parking area. Decide whether it will run straight or curve, and note any slope.
Width. A single-car driveway is typically about 10 feet wide. A double-car driveway is about 20 feet. Local codes may set a minimum width, often so emergency vehicles can get through, so check before you stake the final layout (Bob Vila).
Permits. Many towns need a permit for a new curb cut or driveway. Angi lists permit costs at $50 to $300.
Step 2: Call 811 before you dig
In the US, call 811 (or use your state’s online request) a few days before excavating. Utility companies will mark buried lines for free. Dig by hand near any marked line.
Step 3: Remove grass and topsoil
Strip all grass, roots and organic topsoil from the staked area. Topsoil holds water and compresses unevenly, so gravel laid on it sinks and ruts.
How deep you dig depends on how thick your gravel layers will be. Plan to excavate at least the full depth of your base and top layers, so the finished surface sits at or slightly above the surrounding ground.
Step 4: Grade and compact the subgrade
Rake the exposed soil smooth. Shape it so it slopes away from the house and any buildings, then compact it.
- Compaction tools: a plate compactor works for most residential driveways. Larger jobs use a roller.
- Soft spots: fix any spot that stays soft or pumps under your feet now, by digging it out and filling it with compacted stone. Problems in the subgrade show up later as potholes.
Step 5: Lay geotextile fabric
Roll out a woven geotextile (stabilization) fabric over the compacted soil. Overlap the seams and keep it free of wrinkles.
The fabric stops the gravel from pushing down into the soil and the soil from working up into the gravel. This Old House recommends it to keep gravel from mixing with the ground below (This Old House). It is one of the cheapest ways to make a driveway last longer.
Step 6: Build the base layer
The base carries the weight of your vehicles, so it is the most important layer.
- Material: HomeGuide recommends 3 to 4 inches of crusher run or crushed stone, a mixed-size aggregate from fine dust up to 1-inch stones. The fines lock the larger stones together when compacted (HomeGuide).
- Spreading: spread it evenly with a rake or skid steer.
- Compacting: compact it thoroughly, in two passes of about 2 inches each if you can.
- Soft ground: some builders add a bottom layer of large stone (about 6-inch crushed rock) under the base, as described by Bob Vila.
How deep should a gravel driveway be? HomeGuide gives a minimum total depth of 5 to 6 inches for cars. For heavy trucks or RVs it recommends 8 to 12 inches. Angi’s guidance is similar: 4 to 6 inches.
Step 7: Add the top layer
Spread 2 to 3 inches of surface gravel over the compacted base. Pick angular stone over smooth stone, because angular pieces lock together and stay put.
HomeGuide recommends 3/4-inch to 1-inch crushed stone for the top layer and warns against stone larger than 2 inches. Our guide to the best gravel for a driveway compares the common options, including #57, crusher run and pea gravel.
Ordering tip: schedule a separate delivery for each layer, a few days apart, so each layer can be spread and compacted before the next one arrives (Bob Vila).
Step 8: Shape a crown for drainage
Water is the biggest enemy of a gravel driveway. Grade the surface so it is highest in the middle and slopes down to both sides.
Penn State’s Center for Dirt and Gravel Road Studies recommends a crown of 4% to 6% on unpaved roads (PSU). That is roughly ½ to ¾ inch of drop per foot from the center to the edge.
On a 12-foot-wide driveway, the center should sit about 3 to 4 inches higher than the edges.
Step 9: Finish the edges and drainage
- Edging keeps gravel from spreading into the lawn. Options include steel, brick, concrete curbing, stone pavers and timber. HomeGuide prices edging at $5 to $18 per linear foot.
- Steep driveways need water bars or French drains to send runoff across and off the surface before it cuts ruts (This Old House). Our French drain gravel calculator sizes the stone for a drain trench.
- Culverts under the driveway, where it crosses a ditch, cost $500 to $2,000 (HomeGuide).
Worked example: gravel for a 50 × 12 ft driveway
Here is the material estimate for a 50 ft × 12 ft driveway (600 sq ft), using about 1.4 tons per cubic yard of gravel.
| Layer | Depth | Cubic yards | Tons | Tons +10% |
|---|---|---|---|---|
| Base (crusher run) | 4 in | 7.41 | 10.4 | 11.4 |
| Top (3/4” crushed stone) | 2 in | 3.70 | 5.2 | 5.7 |
| Total | 6 in | 11.1 | 15.6 | 17.1 |
How the base layer is calculated:
- 600 sq ft × (4 ÷ 12) ft = 200 cubic feet
- 200 ÷ 27 = 7.41 cubic yards
- 7.41 × 1.4 = 10.4 tons
The top layer uses the same steps at 2 inches. The extra 10% covers compaction and spreading losses. HomeGuide suggests ordering 10% to 15% extra.
Run your own numbers in the gravel driveway calculator, or convert yards to tons with the gravel tons calculator.
How much does a gravel driveway cost?
| Cost item | Typical range | Source |
|---|---|---|
| Installed, per square foot | $4 – $10 | HomeGuide |
| Average project | $1,800 (typical $500 – $3,500) | Angi |
| DIY materials and equipment | $800 – $2,500 | Angi |
| Professional installation | $1,500 – $6,000 | Angi |
| Grading | $1 – $3 per sq ft | HomeGuide |
| Labor | about 50% of the total; 2–3 workers, 1–3 days | HomeGuide |
| Annual maintenance | $100 – $400 per year | Angi |
The two sources differ because HomeGuide’s per-square-foot figure includes full excavation and base work, while Angi’s averages include many small resurfacing jobs. For gravel prices by type, see our gravel cost guide.
Can I build a gravel driveway myself?
Yes. A gravel driveway is one of the most DIY-friendly hardscape projects. You need these tools:
- Stakes and twine
- Shovel and steel rake
- Wheelbarrow
- Plate compactor (rented)
- Landscape fabric
A skid steer or small excavator, also rentable, makes stripping topsoil and spreading stone far faster on long driveways.
Hire a pro if the site needs:
- heavy grading,
- a culvert, or
- drainage work on a steep slope.
Maintaining a gravel driveway
- Rake the crown back into shape every few months, and after heavy rain (Bob Vila).
- Top up with a thin layer of surface gravel every year or two as stone migrates and wears.
- Fill potholes with crushed stone and compact them, not loose surface gravel.
- Clear snow with the plow blade or snowblower set slightly higher than on pavement, so it does not scrape up stone (This Old House).
Frequently asked questions
How deep should a gravel driveway be? At least 5–6 inches total for cars (HomeGuide), and 8–12 inches for heavy trucks or RVs.
What layers go in a gravel driveway? From the bottom up:
- Compacted subgrade
- Geotextile fabric
- 3–4 inches of compacted crusher run or crushed stone base
- 2–3 inches of angular surface stone
Do I need landscape fabric under a gravel driveway? It is strongly recommended. Woven stabilization fabric keeps gravel and soil from mixing, which is the main cause of sinking and ruts.
How long does it take to build a gravel driveway? Professionals usually finish a typical driveway in 1–3 days (HomeGuide). DIY projects often take a weekend or two, depending on equipment and deliveries.
