Parking Lot Gravel - Material Guide
Picking the right gravel for a parking lot gravel project? This guide covers the materials that fit best, how much you need, and what it costs delivered.
Most parking lot gravel projects fail in the prep stage, not the gravel itself. Soft subgrade, missing fabric, or stone with the wrong gradation all show up six months later as ruts, weeds, or settling. The guide below walks the install in the order a pro crew would tackle it, with the numbers we use to spec material on bids in this region.
Best materials for parking lot gravel
What parking lot gravel needs in a material
- Size and shape: 3/4 inch crushed stone or asphalt millings.
- Drainage: low, sheds water to perimeter swales.
- Compaction: 95% Proctor, rolled in 3 inch lifts.
The three specs above drive every other choice on a parking lot gravel job. Order the wrong size and the surface fails fast. Pick a material that drains the wrong way and you fight standing water or washouts. Get these right and the install steps below take care of the rest.
How to install parking lot gravel
-
1
Strip and proof-roll
Remove topsoil, roll the subgrade, fix soft spots before paving.
-
2
Lay separation fabric
Place geotextile across the full lot footprint.
-
3
Spread base in lifts
Place 6 inches of class-5 in two 3 inch lifts, compact each.
-
4
Cap with wear course
Top with 2 inches of crushed stone or asphalt millings, roll smooth.
How much parking lot gravel material do you need
| Project size | 3 inch depth | 4 inch depth |
|---|---|---|
| 100 sq ft | 0.9 cu yd / 1.3 tons | 1.2 cu yd / 1.7 tons |
| 300 sq ft | 2.8 cu yd / 3.9 tons | 3.7 cu yd / 5.2 tons |
| 600 sq ft | 5.6 cu yd / 7.8 tons | 7.4 cu yd / 10.4 tons |
Quantities above assume crushed stone at roughly 1.4 tons per cubic yard. Pea gravel and river rock run a bit lighter, decomposed granite a bit denser. Add 10 percent waste for irregular shapes and edge losses.
What parking lot gravel costs in 2026
| Region | Delivered per ton | Typical 300 sq ft project |
|---|---|---|
| Northeast | $40 to $68 | $140 to $238 |
| Midwest | $30 to $53 | $105 to $186 |
| South | $29 to $51 | $102 to $179 |
| West | $46 to $84 | $161 to $294 |
The bands below are 2026 delivered prices for full truck loads from a local quarry. Pricing climbs in metros with longer haul distance, drops in markets with quarry competition. Color washes, screenings, and specialty grades sit at the top end of the range.
Parking Lot Gravel mistakes to avoid
- No geotextile, so the base mixes into the soft subgrade.
- Thin base under 6 inches, which fails the first wet winter.
- Skipping the proof roll, so soft spots show up after paving.
- Wear course too thin, so stone potholes form within a year.
