CA-6, Sand and Gravel Delivery in Coles County, IL

Illinois Rock Supply delivers gravel, stone and aggregate in Coles County, IL. If you are building a driveway, bedding a pipe or topping a pad, the question is which material to order.

In this part of Illinois that answer usually starts with CA-6, the dense graded crushed limestone with the fines left in.

Coles County sits on the Grand Prairie till plain of central and eastern Illinois, where deep prairie silt loams sit over dense clay subsoil and water stands rather than runs.

Ground Conditions Across Coles County

Across the Grand Prairie till plain of central and eastern Illinois, the ground is flat to gently rolling Wisconsin Episode till under deep, dark prairie silt loams. Dense clay subsoil sits beneath it with almost no natural fall.

Water stands after heavy rain instead of running off.

That standing water is why drainage matters as much as surface material on a Coles County job. A driveway or pad that holds water needs a clean washed stone layer to move it, not just a fines-bearing surface on top.

Erosion on this ground shows up as sheet wash off bare silt loam and gullying where runoff concentrates. Bank scour follows heavy rain.

Riprap armors those spots.

Base, driveway and paver work runs from the spring thaw into late fall. The ground is slow to dry in a wet spring and frozen solid through winter, so timing a delivery to the working season matters.

Winters here bring repeated freeze and thaw, and frost heave shows up in gravel drives, walks and shallow slabs each spring. Frost depth runs about 36 inches through most of central and eastern Illinois, rising toward the northern edge of the state, and the local building department sets the figure that applies to your job.

Materials Delivered in Coles County

CA-6 is the Illinois base material. It is dense graded crushed limestone with the fines left in.

It is a compacted base for driveways, parking pads, shed and garage bases and trench backfill.

Clean washed stone has no fines, so it drains instead of holding water.

Sand, soil and decorative stone round out a delivery. Mason Sand is the fine clean sand for brick and block mortar, paver joints and sandboxes.

Top Soil is screened Illinois prairie topsoil for lawns, grading and bed prep. River Gravel is rounded stone for beds, borders and dry creek beds.

Choosing the Right Material

Shelby, Clark and Cumberland counties all sit on the same southern till plain and claypan country, loess over old weathered Illinoian drift with tight claypan subsoil and flat to gently rolling relief. That ground is not the same as Coles County's Grand Prairie till plain.

The difference is the subsoil. Claypan is tight and slow, while the Grand Prairie ground here is dense clay till under deep silt loam, flat with almost no fall.

Both hold water, but they hold it differently.

On either ground, a fines-bearing base like CA-6 compacts into a surface, while clean washed stone like CA-7 or CA-11 drains. Which one you order depends on whether the spot needs a surface or a way for water to leave.
