Order CA-6 and Crushed Stone in Clark County, IL
If you are building a driveway, setting a patio base or running drainage, Illinois Rock Supply handles gravel, stone and aggregate delivery in Clark County, IL. The base material here is CA-6, the dense graded crushed limestone Illinois yards sell for drives, pads and trench backfill.
This is Southern till plain and claypan country, where tight subsoil holds water and ground stays soft well into spring. That shapes what you put down and when.
Materials delivered in Clark County
CA-6 is the Illinois base material: crushed limestone with the fines left in.
Order CA-6 for driveways, parking pads, shed and garage bases and trench backfill. It compacts into a tight surface because the fines fill the voids between the stone.
Clean washed stone carries no fines, so water moves through it.
Decorative and soil lines round out the list. River Gravel and Large River Rock cover beds, borders and dry creek beds, while Fill Dirt raises grade before a CA-6 course goes down.
Choosing the right material
Clark County sits in the Southern till plain and claypan country, the same ground region as Crawford County. That ground is loess over old, weathered Illinoian drift, with tight claypan subsoil and flat to gently rolling relief.
Coles County and Edgar County sit in the Grand Prairie till plain, a different ground region. There, deep dark prairie silt loams lie over Wisconsin Episode till, with moraine ridges and old slack-water lake beds.
That difference matters at the base. On the Grand Prairie side the silt loam profile is deeper and better drained, so a compacted base course behaves more predictably through a wet spell.
On claypan ground, water perches instead of draining down. Clean washed stone like CA-7 or CA-11 gives that water somewhere to go.
Ground conditions across Clark County
The claypan sits close to the surface and stops water moving down. Winter and spring rain perches on top of it, so ground stays saturated for weeks and unbound base can pump under traffic.
Across the Southern till plain and claypan country, that saturated clay also heaves drives and walks through repeated freeze and thaw swings. Frost depth in this part of Illinois runs about 30 to 36 inches, and the local building department sets it.
Erosion follows the same water. Sheet and gully erosion opens up where the thin loess is bared, and bank scour and flooding hit low ground along the Wabash on the eastern edge.
Timing is part of the job. The season runs longer here 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.

Questions about ordering in Clark County
What is the difference between topsoil and fill dirt?
Topsoil is the dark, silty surface layer, screened and sold for lawns, grading and bed prep. Fill dirt is bulk material for raising grade and building up low spots before a base course goes down.
Fill dirt is not a growing medium, so it goes under a topsoil layer rather than in place of one.
What is CA-6 and what is it used for in Clark County?
CA-6 is dense graded crushed limestone with the fines left in. It compacts into a firm surface and is ordered for driveways, parking pads, shed and garage bases, and trench backfill.
On claypan ground it works as the base course over fill dirt.
How deep should a gravel driveway base be in Clark County?
Depth depends on your subgrade, the load it carries and how the site drains, so there is no single number that fits every drive. On claypan ground, water perching close to the surface is the main thing to plan around.
