Order Gravel, Stone and Soil in Olympia Fields, IL

Illinois Rock Supply handles gravel and aggregate delivery in Olympia Fields, IL. CA-6, also called road base, is the Illinois base material: dense graded crushed limestone with the fines left in.

It goes under driveways, parking pads, shed and garage bases and trench backfill. Ground here is heavy silt and clay across the Chicago lake plain and the northeastern moraines, and that shapes what you order.

Delivery to Olympia Fields 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 need to size the load.

A dump truck then tips the material on site as one pile. Olympia Fields sits in Cook County, and delivery runs to sites here and to the surrounding area, including Chicago, Cicero, Schaumburg, Evanston and Arlington Heights.

Bulk loads are heavy, so think about where the pile lands before the truck arrives. Clear the spot and keep the approach open so the truck can reach it.

Materials for Olympia Fields Projects

Raising grade and building pads start with fill and sub-base. Fill dirt is bulk fill for lifting a low spot or bringing a pad up to grade before anything else goes down.

Once the pad is at grade, CA-6 goes over it as the compacted base for drives, pads and garage floors. It carries the fines that let it tighten up under a machine.

For a driveway, order Driveway Gravel to surface a drive or top a compacted base. For a patio or walk, Walkway Gravel gives a finer, walkable surface.

For a drain, the clean washed stone is CA-7, also called #57 stone or 1 inch clean stone. It has no fines, so water moves through it, and it beds pipe and trench runs.

CA-11, the 3/4 inch clean stone, does the same work at a smaller size for bedding and concrete flatwork. CA-16 chips, the 3/8 inch limestone chips, bed permeable pavers and top a compacted base.

Ground and Conditions in Olympia Fields

The soil across the Chicago lake plain and the northeastern moraines is heavy silt and clay, with clay-rich till on the moraines inland. That ground sheds water rather than taking it.

Flat ground has little fall, and heavy summer downpours overwhelm yard grades. An under-built base on clay loses its shape fast, so the sub-base has to be right before the surface goes on.

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.

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

Questions About Material in Olympia Fields

What is the best base under pavers in Olympia Fields?

CA-6 is the compacted base course under a paver patio or walk in this market. Over it, lime screenings are the standard bedding layer, and they are what Illinois yards call screenings or stone dust.

Where the pavers are permeable, CA-16 chips bed them instead. On the clay ground here, the base has to be built to suit the load rather than skimped.

Yes. Illinois Rock Supply sells bulk gravel, crushed stone, sand, topsoil and aggregates to contractors and homeowners in Olympia Fields and across Cook County.
