Crushed Stone, Sand and Gravel in Knoxville, IL

If you are planning gravel and aggregate delivery in Knoxville, IL, the job decides the material. A driveway wants CA-6, the dense graded crushed limestone with the fines left in.

Illinois Rock Supply delivers bulk loads across Knox County.

This part of the state sits on deep loess soil that sheds water fast on slopes and holds it in the flats. Where that water goes shapes what you put under a drive, a pad or a drainage run.

Materials for Knoxville Projects

Grading and bed prep start with soil, not stone. Screened topsoil gives a lawn or a seeded slope something to root into, and Illinois prairie topsoil is dark and silty.

Garden soil is blended for raised beds and vegetable plots.

Fill dirt raises grade before anything else goes down. Build the grade up first, then cap it with a compacted CA-6 base course.

For the base itself, CA-6 is the Illinois material. It is dense graded crushed limestone, and it serves driveways, parking pads, shed and garage bases and trench backfill.

Washed stone handles water and concrete. CA-7 is clean 1 inch stone for bedding under pipe and drainage trenches.

CA-11 is the 3/4 inch clean stone sold alongside it for the same work.

Sands and decorative stone round out a load. Torpedo sand is the coarse washed sand for concrete and bedding, mason sand is finer and goes into mortar and paver joints, and river gravel or large river rock finishes beds and downspout areas.

Ground and Conditions in Knoxville

Across the Western Illinois loess uplands and the Mississippi border, the ground is deep loess over older drift. That soil sheds water fast on a slope and holds it in the flats.

On rolling uplands and cut slopes, runoff concentrates and cuts gullies and rills.

That is the reason a base course matters more than the surface stone. A drive that sits on soft, saturated ground moves no matter what you spread on top.

CA-6 with the fines left in knits together into a firm layer once it is compacted.

Where water needs to move instead of sit, use clean washed stone. CA-7 and CA-11 have no fines, so water passes through them into a trench or a drywell rather than backing up under a slab.

Riprap armors a slope or a culvert outlet where flow is concentrated.

The working season runs from the spring thaw into late fall, a little longer than upstate. Winter freeze and thaw still lifts drives and walks each spring, so plan soil and base work around the shoulder seasons.
