Bulk Aggregates for Pathways in Chicago, IL

Illinois Rock Supply handles gravel and aggregate delivery in Chicago, IL, from base stone to bedding fines. CA-6 is the Illinois base material, a dense graded crushed limestone with the fines left in.

On the Chicago lake plain and the northeastern moraines, heavy silt and clay shed water instead of taking it. That shapes what you order for a path, a pad or a drive.

Ground and Conditions in Chicago

Lake plain clay and dense till shed water rather than take it. Flat ground here has little fall, so heavy summer downpours overwhelm yard grades and storm sewers in the older built-up areas.

A thin base course over that clay shows the failure fast. The stone sinks, ruts form along the wheel tracks, and the edges push out after a wet spring.

The fix is a base that carries its own structure and a drainage layer that moves water off the subgrade. CA-6 brings the fines that bind and compact into a firm surface.

CA-7 and CA-11 are washed clean stone with no fines, so water passes through instead of sitting.

Base, driveway and paver work runs from the spring thaw into late fall. Frozen ground stops compaction through the winter, and a wet spring keeps crews off soft clay.

Long cold winters with many freeze and thaw cycles lift drives, walks and slabs every spring.

Materials for Chicago Projects

Fines and screenings do the finish work on paths and walkways. Lime screenings are crushed limestone fines, and in Illinois they are the standard bedding layer under pavers and flagstone.

For a walkway, screenings give you a tight, walkable surface that locks up underfoot. The same material beds pipe and backfills around it, so one load can cover a path and the drainage behind it.

CA-6 is the base that goes under all of it. It is dense graded crushed limestone with the fines left in, and it is what Chicago area yards also call grade 8 or grade 9.

Use it for driveways, parking pads, shed and garage bases and trench backfill.

Clean washed stone handles everything that needs to drain. CA-7 is 1 inch clean stone for bedding under pipe and drainage trenches.

CA-11 is the 3/4 inch clean washed stone sold alongside it for bedding, drainage and concrete work.

Round the order out with a few supporting materials:

• Walkway Gravel for paths and garden walks that need a finer surface.
• Top Soil for lawns, grading and bed prep on dark Illinois prairie soil.
• RipRap for bank protection and slope armoring, set as gradations RR 3 through RR 7.
