Bulk Gravel and Stone Delivery in Piatt County, IL
Illinois Rock Supply brings gravel, stone and aggregate delivery in Piatt County, IL to your site by the ton. The base material here is CA-6, also called road base or 3/4 dense grade.
CA-6 is dense graded crushed limestone with the fines left in. It goes under driveways, parking pads, shed and garage bases and trench backfill.
Piatt County sits on the Grand Prairie till plain of central and eastern Illinois, where deep, dark prairie silt loams cover flat to gently rolling ground.
Ground Conditions Across Piatt County
Base, driveway and paver work on the Grand Prairie till plain runs from the spring thaw into late fall. The ground is slow to dry in a wet spring and frozen solid through the winter.
This part of central and eastern Illinois is some of the flattest ground in the country. Dense clay subsoil sits beneath it with almost no natural fall, so water stands rather than runs after heavy rain.
That standing water is why a clean, open-graded stone layer matters under drains and flatwork. CA-7 and CA-11 are washed clean stone with no fines, so water moves through them instead of pooling.
Bare silt loam erodes as sheet wash, and runoff that concentrates cuts gullies. Riprap armors banks, culvert outlets and pond edges where that concentrated flow hits.
Cold winters 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 to 40 or 42 inches toward the northern edge, and the local building department sets it.

Choosing the Right Material
McLean County, Macon County and De Witt County all sit on the same Grand Prairie till plain of central and eastern Illinois, with the same deep prairie silt loams and the same flat ground. The ground is the same as Piatt County's, so the base and drainage choices carry over.
Across that plain, dense clay subsoil and almost no fall mean water stands after heavy rain. That points to CA-6 for a compacted base and to CA-7 or CA-11 where you need a clean stone layer that lets water through.
