Fill and Base Material Delivered in Hinckley, IL

Illinois Rock Supply handles gravel and aggregate delivery in Hinckley, IL. The base material here is CA-6, also called road base: dense graded crushed limestone with the fines left in.

Hinckley sits in DeKalb County, on the Northern Illinois till plains and Rock River country. That ground is loamy prairie soil over dolomite, and it shapes what you order for a drive or a pad.

Materials for Hinckley Projects

Raising grade and building pads come first on a lot with flat, tight ground. Fill goes down to bring the subgrade up, then a compacted base course carries the load.

That order matters more than the material you pick for the surface.

Start with Fill Dirt when you need bulk volume to raise a pad or level a low spot. It is the cheap bulk layer under everything else, and it is not a wearing surface.

Over that goes CA-6, the Illinois base material. Dense graded crushed limestone with the fines left in, it compacts into a firm base for driveways, parking pads, shed and garage floors, and trench backfill.

For a driveway surface, Driveway Gravel tops a compacted base. For a patio or a walk, Lime Screenings bed pavers and flagstone; that is the standard bedding layer in Illinois, and yards here call it screenings.

Ground and Conditions in Hinckley

The soil across the Northern Illinois till plains and Rock River country is loamy prairie soil over dolomite. Under it, till is often tight, and the flat ground holds a high water table.

A base built thin over that ground moves when the subgrade does.

Water is the other half of the problem. Snowmelt and spring rain on frozen ground push water across the surface instead of into it.

A clean washed stone under a drain or a downspout run gives that water somewhere to go.

Use CA-7 for pipe bedding, French drains and concrete flatwork, and 3/4" Crushed Stone for the same work in the CA-11 size. Both are washed clean stone with no fines, so water passes through them.

The working season runs from the spring thaw into late fall, a little shorter than downstate. Frozen ground stops compaction, so grade work and base work belong in the open months.

Frost action in unbound base is heavy in the northern counties, and the local building department sets footing depth.

Questions from Hinckley Buyers

What is the best base under pavers in Hinckley?

CA-6 is the compacted base course, and lime screenings are the bedding layer the pavers sit in. The screenings are crushed limestone fines, and they are the standard bedding in Illinois.

Order both and keep the base course separate from the bedding.
