Bulk Material Delivery in Winnetka, IL

Illinois Rock Supply handles gravel and aggregate delivery in Winnetka, IL, and the loads start with CA-6. That is the dense graded crushed limestone this market calls road base, with the fines left in.

Sizing a load takes a minute with the calculator on each product page, then you pick the material.

Winnetka sits on the Chicago lake plain, where heavy silt and clay shed water instead of taking it. That makes washed stone the material to think about first on most lots here.

Materials for Winnetka Projects

Washed stone is where drainage work starts. It has no fines to hold water, so a trench filled with clean stone gives water somewhere to go instead of letting it sit against a foundation.

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

3/4" Crushed Stone, or CA-11, is the 3/4 inch clean washed stone that goes alongside CA-7. It beds pipe and drainage runs and works under concrete.

CA-16 Chips are the small 3/8 inch chips. They bed permeable pavers, drain around tanks and top a compacted base.

Drain Rock covers French drains, drywells, foundation drains and downspout runs. Contractors here are as likely to ask for CA-7 or CA-11 by number for the same work.

For a driveway or a parking pad, CA-6 is the base course. It compacts into a firm surface with the fines binding the stone together.

Delivery to Winnetka 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 then tips the load in one pile at the site.

Nothing else is needed from you.

Coverage runs across Cook County, including Evanston, Arlington Heights, Schaumburg, Cicero and Chicago. If your site is in Winnetka, it is inside that area.

Have the drop spot clear before the truck arrives. A bulk load is heavy, so the pile needs room and ground that can carry a truck.

Ground and Conditions in Winnetka

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.

Across the Chicago lake plain and the northeastern moraines, the ground is heavy silt and clay close to the lake and clay-rich till inland. That soil sheds water rather than taking it, and flat ground has little fall.

Heavy summer downpours overwhelm yard grades and storm sewers in the older built-up areas. A clean stone drainage layer is what moves that water away from a foundation or a low corner of a lot.

Long cold winters bring many freeze and thaw cycles, and frost lifts drives, walks and slabs every spring. Frost depth is about 42 inches in northeastern Illinois, the figure jurisdictions there carry in the residential code, and the local building department sets it.

What gravel is best for a driveway in Winnetka?
