How deep should a gravel driveway base be in Iroquois County?

No single depth fits every driveway. The clay subsoil here holds water and has almost no fall, so a base has to be thick enough to bridge soft ground. Frost heave also moves gravel drives and walks each spring. The local building department sets frost depth, about 36 inches through most of central and eastern Illinois.

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

Start with CA-6, the dense graded crushed limestone Illinois yards sell as road base.

Ground Conditions Across Iroquois County

Iroquois County sits on 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.

This is some of the flattest ground in the country, with dense clay subsoil beneath it and almost no natural fall. Water stands rather than runs after heavy rain.

A thin base course shows that fast. Water sits on the clay, works into the stone and pumps fines to the surface, and the surface ruts under a tire.

The fix is a base built thick enough to bridge the soft subsoil and a clean drainage layer where water has nowhere to go. Sheet erosion off bare silt loam and gullying where runoff concentrates are the other local problems.

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 toward the northern edge, and the local building department sets it.

Materials Delivered in Iroquois County

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

Use CA-6 for driveways, parking pads, shed and garage bases and trench backfill. Crusher Run is the same idea under a secondary name.

Clean stone carries no fines, so it drains.

Choosing the Right Material

Kankakee County shares no ground with Iroquois County. Its ground is heavy silt and clay of the old Lake Chicago lake plain, with clay-rich till in the Valparaiso, Tinley and Lake Border moraines inland.

That clay holds water far longer than prairie silt loam, so a base there needs more clean drainage stone under and beside it. CA-7 and CA-11 do that work.

Vermilion County and Ford County sit on the same Grand Prairie till plain as Iroquois County. The ground is the same, so the base and drainage choices are the same.
