Bulk Material Delivery in Westchester, IL

Illinois Rock Supply handles gravel and aggregate delivery in Westchester, IL, with bulk loads tipped at your address. This part of Cook County sits on clay-rich ground, and clay sheds water instead of taking it.

That shapes what you put down: a compacted CA-6 base for drives and pads, and clean washed stone where water has to move.

CA-6, also called road base, is dense graded crushed limestone with the fines left in. It builds the firm layer under a drive, a parking pad, a shed floor or a trench backfill.

Materials for Westchester Projects

Water is the hard part of a Westchester yard. Clay and dense till push storm water sideways, and flat ground gives it nowhere to go.

A French drain, a drywell or a downspout run gives that water a path, and the stone in it has to be washed clean so the voids stay open.

Start with the coarse end. #4 Crushed Stone is large clean stone for trench bottoms, heavy drainage and construction entrances.

CA-7 is the washed 1 inch stone Illinois contractors specify for bedding under pipe and drainage trenches. 3/4" Crushed Stone, sold locally as CA-11, is the 3/4 inch clean washed stone for bedding, drainage and concrete work.

Below that, CA-16 Chips are 3/8 inch limestone chips for drainage around tanks and for topping a compacted base. Lime Screenings are the crushed limestone fines used to bed pavers and flagstone and to backfill around pipe.

For the base course itself, CA-6 is the material Illinois yards specify by that number, and it is what a drive, pad or garage base is built from. Fill Dirt raises grade before that base goes down.

Sand and soil round out a job. Washed Sand, which Illinois yards call torpedo sand, is the coarse washed sand for concrete and bedding.

Top Soil covers lawns and bed prep, and Shredded Mulch holds moisture in beds through a summer.

Delivery to Westchester and the Surrounding Area

Illinois Rock Supply delivers bulk material to Westchester and to addresses across Cook County, including Chicago, Cicero, Schaumburg, Evanston and Arlington Heights. You order online and a dump truck tips the load in one pile at your site.

Quantities are ordered by the ton or by the yard, and each product page has a calculator to help you size the load. Pick your delivery date at checkout and the truck arrives on it.

Think about where the pile lands before the truck rolls. A tipped load needs a firm, reachable spot, and on soft clay that means ground that has already drained.

If your base material and your drainage stone are both coming, order them together and plan the pile position for the first drop.

Ground and Conditions in Westchester

Across the Chicago lake plain and the northeastern moraines, the ground is heavy silt and clay close to the lake and clay-rich till further inland. Both shed water rather than absorb it.

Flat lots have little fall, so a heavy summer downpour can overwhelm a yard grade and sit there.

That is why a drainage layer matters as much as the base. Clean washed stone lets water pass through and away; a fines-bearing material holds it.

Keep the two separate in your plan, because CA-6 is a base and CA-7 or CA-11 is the drainage stone.

Timing follows the season. 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 until it drains.

Frost is part of the picture here. Long cold winters with repeated freeze and thaw cycles lift drives, walks and slabs every spring, and gravel surfaces stay soft until the ground drains.

Frost depth figures are set by the local building department, so check with Westchester before you plan anything structural.
