Pit Run
Varies — typically 6" minus with native fines
Unprocessed gravel pulled straight from a pit — a natural mix of rock, sand, silt, and fines. The cheapest structural fill for deep lifts, building pads, and below-base work.
Where it shines
- ✓ Deep structural fill on building pads
- ✓ Base layer below road base on long driveways
- ✓ Rough grade fill on lots and yards
- ✓ Access road construction
- ✓ Filling over-excavated trenches
Not the right choice for
- ✕ Finish driveway surface (too uneven, too dusty)
- ✕ Anything decorative
- ✕ Under concrete slabs without a clean base layer on top
What is pit run?
Pit run is exactly what it sounds like — gravel pulled directly from a gravel pit and hauled without being crushed, screened, or washed. You get whatever nature put in the ground: a mix of larger rocks (often rounded river rock), sand, silt, and fines.
Because it skips the processing step, pit run is usually the cheapest bulk material you can get for fill work.
Where pit run shines
When you need to move a lot of volume — building pads, over-excavations, rough grade fill, long access roads — pit run wins on price per cubic yard. It’s not pretty, it’s not a finish surface, but it packs well enough for structural work when you put something better on top.
Where pit run is wrong
Pit run alone doesn’t make a good finish driveway. The rounded rock doesn’t lock the way crushed material does, and the surface will always feel loose and dusty. It’s also not ideal anywhere the surface will be visible or walked on regularly.
The right pattern is almost always: pit run deep, road base on top, then optional decorative rock or asphalt millings as the finish layer.
Ordering tips
- Ask what pit we’re pulling from. Pit run from one pit may be mostly clean gravel; from another, heavy with clay. Matters for what you’re using it for.
- Plan for layering. Pit run is a foundation material; budget for a cap layer.
- Moisture matters for compaction. Too dry and it won’t pack; too wet and it turns to soup. Compact in 6–8 inch lifts.
Coverage
Pit run is usually placed in thick lifts (6–12 inches) for bulk fill, not calculated by thin coverage. For a building pad, figure cubic yards from your excavation volume.

What's the difference between pit run and road base? +
Pit run is dug straight out of the ground — natural rock, sand, and fines mixed together, often with rounded river rock. Road base is crushed aggregate with angular edges and engineered gradation. Pit run is cheaper but doesn't "lock in" as tightly when compacted. Most driveways use pit run as deep fill with road base as the top layer.
Can I use pit run for a driveway? +
As a deep base layer, yes — especially for long rural driveways where you need a lot of fill. But you'll want at least 3–4 inches of road base on top for a stable, smooth surface.
Is pit run the same everywhere? +
No — it literally varies pit to pit. Some is mostly clean gravel; some has heavy clay and silt. Ask us what's coming out of the pit we're pulling from before a big order.
