Gravel Driveways: How They're Built, What They Cost, Who to Hire

Why is a gravel driveway usually the first thing built on raw land?

Because every truck that follows — the well rig, the septic installer, the concrete mixer — needs a road that won't sink. A gravel driveway is often the first permanent improvement on a rural lot.

It's also the cheapest durable surface. Asphalt and concrete cost several times more per square foot, and many rural owners never upgrade because good gravel does the job.

Build the base heavy enough for construction traffic now. A well rig and a loaded concrete truck are far heavier than the family car.

How is a gravel driveway built?

A lasting gravel driveway is built in layers: a shaped subgrade, a coarse base, and a finer top — with a crown and ditches to shed water. Most failures trace back to skipping the base or the drainage.

1. Clear and strip. Remove topsoil, roots and organic matter. They rot and settle.
2. Shape the subgrade. Grade a crown so water runs to both sides, and cut shallow ditches along the edges.
3. Lay geotextile (soft ground). Fabric keeps the stone from pushing down into clay.
4. Base layer. Large crushed stone, 4 to 6 inches, compacted.
5. Middle layer. Smaller crushed stone that locks into the base.
6. Surface layer. Crushed stone with fines (crusher run or similar) that packs hard. Compact it.

Total depth is commonly 8 to 12 inches for a rural driveway that carries construction traffic.

How much does a gravel driveway cost?

Most contractors charge $2 to $5 per square foot installed, and DIY runs $1 to $3. For a 12-foot-wide, 200-foot rural driveway (2,400 sq ft), that's roughly $4,800 to $12,000 installed.

Distance to the quarry moves the bill more than which stone you pick. Delivery runs $10 to $25 a ton, and past 10 to 15 miles the haul can cost as much as the stone.

Which gravel should I use?

Use angular crushed stone, not round gravel. Angular edges lock together; round pea gravel rolls and ruts.

• Base: large crushed stone (such as #3 or #4).
• Middle: #57 stone.
• Top: crusher run (also sold as #411, ABC, or dense-grade aggregate). The stone dust packs into a hard surface.

Names vary by region and quarry. In much of Texas, caliche — a naturally cemented limestone soil — is a popular low-cost surface that packs hard when compacted, though it gets muddy and dusty in extremes.

How do I stop a gravel driveway from washing out?

Control the water. Almost every washout, pothole and rut starts with water running down the driveway instead of off it.

• Crown the center so water sheds sideways.
• Ditch the edges to carry water away.
• Add water bars or turnouts on slopes to kick water off before it builds speed.
• Install culverts where the driveway crosses a ditch or low spot.
• Keep the surface layer topped up — fines wash out over time.

On steep grades, consider geocell grid or switching the steepest section to paving.

Do I need a culvert or a county driveway permit?

Usually, yes, if your driveway connects to a public road. Most counties and state DOTs require a driveway or access permit, and many require a culvert of a minimum size where you cross the roadside ditch.

The road department sets the culvert size, length and sometimes material. Some install it for you for a fee; others require a contractor. Check before you order pipe.

Drainage work beyond the culvert — French drains, swales — is covered in our drainage hub.

How long does a gravel driveway last?

The base can last decades if water is controlled; the surface needs topping up every few years. Plan for regular grading and a fresh layer of surface stone as it thins.

Annual maintenance is mostly regrading potholes, clearing ditches and adding stone where it's worn. A small tractor with a box blade handles most of it.

How do I hire a gravel driveway contractor?

Hire someone who grades, not just someone who delivers stone. A dump truck dropping gravel on dirt isn't a driveway.

Ask every contractor:

• How deep is the base, and which stone for each layer?
• Is fabric included on soft ground?
• Will you crown it and cut ditches?
• Who handles the culvert and county permit?
• Is the price per square foot, per ton, or lump sum? What's the delivery charge?
• Will it hold a well rig and concrete trucks?

Many land clearing and excavation contractors build driveways too — combining jobs saves a mobilization fee.
