Rip Rap and Bulk Aggregates for Oak Brook, IL

Looking for gravel and aggregate delivery in Oak Brook, IL for a bank that keeps washing out? Illinois Rock Supply delivers bulk stone, sand and soil across DuPage County.

Most of that work starts with CA-6, the dense graded crushed limestone used as road base here. On the Chicago lake plain and the northeastern moraines, heavy silt and clay ground sheds water instead of taking it, so where the water goes matters as much as what you put down.

Materials for Oak Brook Projects

Bank protection, swale lining and slope armoring call for coarse, open stone. These sizes are the ones that stand up to moving water.

Coarse Stone for Slopes, Swales and Banks

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

#4 Crushed Stone is 1 1/2 inch clean stone. It works for construction entrances, heavy drainage and trench bottoms.

Railroad Ballast is 3 inch clean stone for track beds, hard standing and severe drainage. Illinois yards sell this size as CA-1 or RR1.

Washed Stone for Drainage and Bedding

CA-7 is washed clean stone with no fines, for bedding under pipe, drainage trenches, French drains and concrete flatwork. 3/4" Crushed Stone, sold as CA-11, is the 3/4 inch clean washed stone that goes alongside it.

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.

Fine Material for Beds and Surfaces

Lime Screenings are crushed limestone fines for paver and flagstone bedding and for backfill around pipe. They are the standard bedding layer in Illinois.

CA-6 is dense graded crushed limestone with the fines left in, for driveways, parking pads, shed and garage bases and trench backfill.

Delivery to Oak Brook 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 order.

A dump truck tips the load in one pile on site. Plan for the pile to land where you want the material to sit, because the truck does not spread it.

Illinois Rock Supply delivers to Oak Brook and to the rest of DuPage County, including Naperville, Wheaton, Downers Grove, Elmhurst and Lombard.

Have the delivery spot clear before the truck arrives. A soft lawn or a blocked drive leaves nowhere for the pile to go.

Ground and Conditions in Oak Brook

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.

Across the Chicago lake plain and the northeastern moraines, lake plain clay and dense till shed water rather than take it. Flat ground has little fall, and heavy summer downpours overwhelm yard grades and storm sewers in older built-up areas.

That is why swales, bank edges and low spots need coarse open stone rather than a fines-bearing material. Water moves through clean stone and sits on top of clay.

Stream bank scour after heavy rain is the other side of the same problem. RipRap and #4 Crushed Stone armor those edges so moving water meets stone instead of bare soil.

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

Questions About Stone and Delivery in Oak Brook

What stone should I use for drainage in Oak Brook?

Use clean washed stone with no fines. CA-7 and CA-11 are the 3/4 inch to 1 inch sizes for French drains, foundation drains and downspout runs, and CA-16 chips work for tighter bedding.

Fines-bearing material like CA-6 is a base, not a drainage layer, and it holds water instead of passing it.

What should I have ready when the truck arrives?

Clear the spot where you want the pile and make sure the truck can reach it. The load is tipped in one pile and is not spread or placed.

Have your quantity settled before the delivery date, since the driver takes no instruction on where the material goes.
