Bulk Aggregates for Patios in Highland Park, IL

Illinois Rock Supply brings gravel and aggregate delivery in Highland Park, IL to patios, driveways, walkways and planting beds. Start with CA-6, the dense graded crushed limestone this market calls road base.

Clay ground across the Chicago lake plain and the northeastern moraines sheds water instead of taking it, so what sits under a patio matters as much as the surface.

Ground and Conditions in Highland Park

A patio base that is too thin tells on itself the first wet season. The slabs rock, joints open, and water pools at the low corner instead of leaving.

The ground under much of this area is heavy silt and clay, and it sheds water rather than absorbing it. Flat ground gives that water little fall, so it sits where the grade lets it.

Long cold winters with repeated freeze and thaw lift drives, walks and slabs every spring. Northeastern Illinois jurisdictions carry a frost depth of about 42 inches for footings, and the local building department sets the figure.

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.

Materials for Highland Park Projects

Bedding is where a patio or flatwork job is won. The layer directly under pavers or slabs has to sit flat, stay put, and let water move.

CA-6 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.

You can order CA-6 for the compacted base course below the bedding layer.

Lime screenings handle the bedding layer itself. These are crushed limestone fines, and they are the standard bedding for pavers and flagstone in Illinois, plus backfill around pipe.

Order Lime Screenings for that job.

Where water has to drain instead of being held, use clean washed stone. CA-7 is 1 inch clean stone with no fines, for bedding under pipe, drainage trenches, French drains and concrete flatwork.

Order CA-7.

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

For the concrete and leveling side of a patio build, torpedo sand is the coarse washed sand Illinois yards sell. Order Washed Sand for concrete, leveling and bedding.

Delivery to Highland Park and the Surrounding Area

Quantities are ordered by the ton or by the yard, so you pick the unit that matches how you measured. Each product page has a calculator if you would rather size the load before checkout.

You order online, choose your quantity, and pick a delivery date at checkout. A dump truck then tips the material in one pile at the address you give.

Highland Park sits in Lake County, and Illinois Rock Supply delivers bulk material across the county, including Waukegan, Mundelein, North Chicago, Gurnee and Buffalo Grove.

Plan the drop spot before the truck arrives, since the pile lands where it is tipped and stays there. Once it is on site, you move it from the pile to the work.
