CA-6, also called road base, is the dense graded crushed limestone most drives and pads here sit on.

Westmont sits in DuPage County, on the clay-heavy ground of the Chicago lake plain and the northeastern moraines. That ground sheds water instead of taking it, so washed stone earns its place on a lot here.

Materials for Westmont Projects

Washed stone is the material this area needs most for water. Clean stone has no fines, so water moves through it instead of pooling on top.

That is what makes it the right choice for French drains, drywells and downspout runs.

CA-7 is the 1 inch clean stone, also called #57 stone, used for bedding under pipe and around drainage trenches. 3/4" Crushed Stone, sold here as CA-11, does the same work at a slightly smaller size and beds concrete flatwork.

For tighter spots, CA-16 Chips is the 3/8 inch washed stone that goes under permeable pavers and around tanks. At the coarse end, #4 Crushed Stone is the large clean stone for trench bottoms and heavy drainage.

Fines-bearing material has its own jobs. CA-6 is the dense graded crushed limestone with the fines left in, for driveways, parking pads, shed and garage bases and trench backfill.

Lime Screenings bed pavers and flagstone and backfill around pipe.

Sand and soil round out a load. Washed Sand, which yards here call torpedo sand, is the coarse washed sand for concrete and leveling.

Top Soil covers lawns, grading and bed prep.

Delivery to Westmont and the Surrounding Area

You order online, choose a quantity by the ton or by the yard, and pick a delivery date at checkout. A dump truck tips the load on site.

That is the whole process, and it works the same for a driveway job or a drainage run.

Illinois Rock Supply delivers bulk material across Westmont and the rest of DuPage County, including Naperville, Wheaton, Downers Grove, Elmhurst and Lombard. If your site is in one of those places, the same online order covers it.

Bulk loads arrive as one tipped pile, so it helps to know where that pile should land before the truck shows up. Size the load with the calculator first, then set your date.

Ground and Conditions in Westmont

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

Timing a delivery around that window matters as much as the material itself.

The ground across the Chicago lake plain and the northeastern moraines is heavy silt and clay, with dense till inland. That ground sheds water rather than absorbing it, and flat lots have little fall to move it along.

Heavy summer downpours overwhelm yard grades and storm sewers in the older built-up areas.

That is the case for clean washed stone on drainage work. Water that cannot soak into clay has to be carried somewhere, and CA-7, CA-11 and CA-16 give it a path.

Bare clay lots also wash off in a hard rain, which is where rip rap and ground cover come in.

Long cold winters bring many freeze and thaw cycles, and frost lifts drives, walks and slabs every spring. Gravel surfaces stay 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 the figure.
