Why Choose Gravel? The Smart Homeowner’s Overview
Gravel driveways deliver instant curb appeal, quick drainage, and a price tag that’s kind to any budget. Unlike asphalt or concrete, you can walk and drive on gravel the same day it’s laid, and repairs are as simple as raking and topping off. This Gravel Driveway Installation Step-by-Step Guide walks you through everything—from first measurements to the final roll of the wheel—so you can decide whether to DIY or hire a pro with confidence.
Step 1: Plan & Measure Like a Pro
Check Local Codes & Utilities
Call 811 (the national “call-before-you-dig” hotline) at least 72 hours before you break ground. Many towns also require a driveway permit if you connect to a public road; ask your building department about setbacks, width limits, and edging requirements.
Mark the Path & Calculate Square Footage
Drive stakes every 6–8 ft along the centerline, then tie string to visualize the shape. Measure length × width to get square footage. A 12-ft width fits two passenger cars side by side; 10 ft is fine for single-lane drives.
Choose the Right Gravel Layering System
- Sub-base (0–4 in.): fist-sized #1 stone for load-bearing strength.
- Base (4–8 in.): ¾-inch clean crush for drainage.
- Surface (2–3 in.): ⅜-inch pea gravel or crusher run for smooth tread.
Pro tip: Order 10 % extra to account for compaction.
Step 2: Gather Tools & Materials
Rent the big stuff for a weekend; your back will thank you.
- Skid-steer or mini-excavator (optional but saves hours)
- Vibratory plate compactor (3500 lb force minimum)
- Landscape fabric (woven, 4–5 oz weight)
- Sturdy edging (steel, aluminum, or pressure-treated timber)
- Wheelbarrow, metal rake, shovel, hand tamper, 4-ft level, and a string line
Step 3: Excavate to the Correct Depth
How Deep Should You Dig?
Total depth = gravel layers (8–12 in.) + 2 in. for settlement. In cold climates, go 14 in. to place the sub-base below the frost line. Spray-paint the finished excavation line on the grass so you can see your progress.
Establish a 2 % Crown for Drainage
Water should run off the center to either side, not pool. For every 10 ft of width, the center should be 2.4 in. higher than the edges. Use a string line and line level to check as you dig.
Step 4: Lay the Foundation—Sub-Base & Base Layers
Install Geotextile Fabric
Unroll woven landscape fabric across the excavated floor, overlapping edges by 12 in. Fabric stops stone from migrating into the soil and prevents muddy potholes later.
Add & Compact Sub-Base
Dump #1 stone in 4-in. lifts. Compact each lift with three full passes of the plate compactor in two directions. Spray a light mist to keep dust down; moisture helps consolidation.
Repeat for the Base Layer
Drop ¾-inch clean crush the same way—4 in. at a time, compact, check level. The finished base should feel like polished concrete when you walk on it.
Step 5: Lock It In With Edging
Steel or aluminum edge restraint keeps gravel from scattering into the lawn and maintains crisp lines. Set edging 1 in. above the final gravel height, anchoring with 12-in. steel stakes every 3 ft. Back-fill the outside lip with soil and sod for a seamless look.
Step 6: Spread the Surface Gravel
Choose the Right Topdressing
- Crusher run: Mix of fines and ¾-in. stone; packs tight, great for steep grades.
- Pea gravel: Smooth, rounded; best for flat drives where you want a barefoot-friendly finish.
Technique for Even Coverage
Dump piles every 8–10 ft, then use a landscape rake to pull gravel outward in 2-in. layers. Maintain your 2 % crown as you work. Stop periodically and check thickness with a tape; you want a consistent 2–3 in. after final compaction.
Step 7: Compact & Clean Up
Make two passes with the plate compactor—longitudinal then transverse. Lightly mist the surface; moisture binds the fines and reduces dust. Sweep excess off any adjoining concrete or asphalt to prevent staining.
Long-Term Maintenance Schedule
Monthly
- Rake high spots back into low areas.
- Check edging for loose stakes.
Seasonally
- Top-dress with ½–1 in. of fresh gravel every spring.
- Apply calcium chloride or magnesium chloride for dust control in dry climates.
Annually
- Re-grade with a box blade or landscape rake to restore crown.
- Inspect fabric at the edges; patch if exposed.

Common Problems & Quick Fixes
Ruts & Potholes
Caused by poor compaction or thin base. Cut out the soft spot, add fresh base, compact in lifts, top-match surface gravel.
Gravel Migration
Install additional edging or a 6-in. strip of concrete curbing at the driveway mouth. A 10-mph speed bump of packed gravel also slows cars and keeps stone in place.
Muddy Spots After Rain
Usually means the sub-base is sitting in saturated soil. Add a French drain alongside the drive or deepen the excavation by 4 in. and add an extra layer of #1 stone.
Gravel Driveway FAQ
With proper base construction and yearly top-dressing, 10–15 years is typical. Heavier truck traffic or poor drainage shortens life; routine raking and grading extend it.
Only if the slab is crack-free and sloped for drainage. Drill 1-in. holes every 12 in. to prevent water from pooling under the gravel. Expect some shifting at the edges; edging is critical.
Crusher run with fines packs tight and resists frost heave. Avoid pea gravel—it rolls under tires and is hard to shovel. Apply salt sparingly; it breaks down limestone dust and weakens compaction.
Light passenger vehicles: same day. Heavy trucks or RVs: wait 48–72 hours so the base can fully interlock. Spread loads evenly the first month to avoid ruts.
