CA-7, Stone and Soil Delivery in Schaumburg, IL

Illinois Rock Supply handles gravel and aggregate delivery in Schaumburg, IL, and the ground here sets the terms. Across the Chicago lake plain and the northeastern moraines, heavy silt and clay shed water instead of taking it.

That matters before you pick a surface. CA-6, the dense graded crushed limestone with the fines left in, gives you a compacted base for drives, pads and trench backfill.

Materials for Schaumburg Projects

Washed stone is the clean side of the yard, and it is what a drainage job calls for. Clean stone has no fines, so water moves through the voids instead of sitting in the material.

CA-7, also sold as #57 stone or 1 inch clean stone, is washed stone for bedding under pipe, drainage trenches and French drains. It also beds concrete flatwork.

CA-11 is the 3/4 inch clean washed stone that sits alongside CA-7 for bedding, drainage and concrete work.

For a downspout run or a drywell, the stone has to stay open. CA-16 chips are 3/8 inch limestone chips for drainage around tanks and for topping a compacted base.

Lime screenings are the fine end, crushed limestone for paver and flagstone bedding and for backfill around pipe. Lime Screenings are the standard bedding layer in Illinois.

Riprap is the heavy end, broken stone for bank protection, culvert outlets, pond edges and slope armoring.

RipRap suits ground that has to hold against moving water.

Sand and soil round out a job. Torpedo sand is the coarse washed sand for concrete, leveling and bedding, sold as Washed Sand.

Screened topsoil covers lawns, grading and bed prep.

CA-6 is the base course under all of it. CA-6 is the Illinois name; Chicago area yards also call it grade 8 or grade 9, and it is the same material.

Delivery to Schaumburg and the Surrounding Area

You order online, choose a quantity by the ton or by the yard, and pick a delivery date at checkout. Each product page has a calculator if you want to size the load before you commit.

A dump truck tips the load in one pile on site. Delivery reaches Schaumburg and the rest of Cook County, including Chicago, Cicero, Evanston, Arlington Heights and Palatine.

Have the drop spot clear before the truck arrives. Bulk material comes in one pile, so the ground it lands on is the ground it stays on.

Ground and Conditions in Schaumburg

Timing runs the season here. Base, driveway and paver work goes from the spring thaw into late fall, and frozen ground stops compaction through the winter.

A wet spring keeps crews off soft clay, so a delivery date that lands after the ground drains beats one that lands early. Watch the forecast before you schedule.

Across the Chicago lake plain and the northeastern moraines, clay and dense till shed water rather than take it. Flat ground has little fall, and heavy summer downpours overwhelm yard grades.

Sheet wash off bare clay lots is the other problem, so bare ground wants cover or a surface. That is where the washed stone earns its place: a drainage layer under a downspout run or a French drain moves water away from the house.

Frost is real here. Long cold winters with many freeze and thaw cycles lift drives, walks and slabs every spring and leave gravel surfaces soft until the ground drains.

Northeastern Illinois jurisdictions carry a frost depth of about 42 inches in the residential code, and the local building department sets it.

Questions About Gravel and Stone in Schaumburg

Do you deliver CA-6 to Schaumburg, IL?

Yes. Illinois Rock Supply delivers CA-6 and other bulk aggregate to Schaumburg and the surrounding part of Cook County.

You order online by the ton or by the yard, pick a delivery date at checkout, and a dump truck tips the load in one pile at your site. CA-6 is the dense graded crushed limestone with the fines left in, used for driveways, parking pads, shed and garage bases and trench backfill.

What gravel is best for a driveway in Schaumburg?

It depends on what the drive needs. CA-6 is the compacted base for a new drive, and it is the Illinois base material.

If you are surfacing an existing drive or topping a compacted base, driveway gravel is the layer that takes the traffic. On ground that stays wet, a clean washed stone under the surface helps water move.
