Gravel, Stone and Soil for Crawford County, IL
Illinois Rock Supply delivers gravel, stone and aggregate delivery in Crawford County, IL. Start with CA-6.
Under it sits tight claypan subsoil. Water stops there and sits, so a base that carries a truck needs the right stone under it.
Materials delivered in Crawford County
Order by project. A driveway, a patio, a drain and a garden bed each take a different stone.
CA-6 is the Illinois base material. It is dense graded crushed limestone with the fines left in, and Article 1004.01 of the Standard Specifications for Road and Bridge Construction sets it as gradation CA 6.
Use it for driveways, parking pads, shed and garage bases and trench backfill. It goes down as the base course, not as the finished surface.
For clean stone. CA-7 and CA-11 cover the 1 inch and 3/4 inch washed sizes, and CA-16 covers 3/8 inch chips.
Sand follows the same pattern. Torpedo sand is the coarse washed sand for concrete and bedding, and mason sand is the finer clean sand for mortar and paver joints.
Ground conditions across Crawford County
Across the Southern till plain and claypan country, loess sits over old, weathered Illinoian drift. The claypan subsoil below it is tight and slow.
That claypan sits close to the surface and stops water moving down. Winter and spring rain perches on top of it, and the ground stays saturated for weeks.
An unbound base over saturated clay pumps under traffic. Build the base for that ground, and put a clean washed layer where water has to move.
Where the thin loess is bared, sheet and gully erosion follows. Riprap armors slopes, culvert outlets and pond edges against it.
The working season is longer than upstate at both ends, but a wet winter and spring keep sites soft well into April. Late summer and fall are the reliable windows.
Winters here are cold but shorter than in the north, with frequent freeze and thaw swings that work on saturated clay. That heaves drives and walks.
Frost depth is set by the local building department.

Choosing the right material
Richland County, Lawrence County and Clark County all sit on the same Southern till plain and claypan country ground as Crawford County. Loess over weathered Illinoian drift, with the same tight claypan subsoil.
So the ground is the same, and the material choice is the same. CA-6 for the base, CA-7 or CA-11 where water has to drain, and riprap where a slope or bank needs armoring.
