Bulk Aggregates for Patios in Aurora, IL

For gravel and aggregate delivery in Aurora, IL, the working season sets the schedule. Base, driveway and paver work runs from the spring thaw into late fall, and frozen ground stops compaction through the winter.

Illinois Rock Supply delivers bulk material across Kane County, starting with CA-6, the dense graded crushed limestone this market builds on.

Across the Chicago lake plain and the northeastern moraines, heavy silt and clay shed water rather than take it. That shapes what you put under a patio before anything else matters.

Ground and Conditions in Aurora

Clay-rich ground moves when it takes on water and again when it dries. A patio base that is too thin telegraphs that movement straight up through the pavers, and you see it as a dip or a rocker at the corner of a slab.

Bedding is where that shows first. Lime screenings, the crushed limestone fines Chicago area yards call screenings, spread and level under pavers and flagstone.

They give you a thin, true layer to set into rather than a surface that shifts underfoot.

Flat ground with little fall is the other half of the problem. Heavy summer downpours overwhelm yard grades, so water needs somewhere to go before it sits against the edge of a patio or the side of a slab.

Frost is part of the same picture. Long cold winters with many freeze and thaw cycles lift drives, walks and slabs every spring and leave gravel surfaces soft until the ground drains.

Work gets scheduled around that, not through it.

Materials for Aurora Projects

Start with CA-6, also called CA6 or road base. It is dense graded crushed limestone with the fines left in, and it is the compacted base under drives, parking pads, shed and garage bases and trench backfill.

Under a patio, CA-6 does the structural work below the bedding layer. Lime screenings level above it.

Together they cover the two layers most flatwork in this area is built on.

Washed clean stone has no fines, so it drains rather than compacts. CA-7, also sold as #57 stone or 1 inch clean stone, beds pipe and drainage trenches and sits under concrete flatwork.

CA-11, the 3/4 inch clean washed stone, does the same job at a smaller size.

Concrete and mortar take sand, not stone. Torpedo sand is the coarse washed sand Illinois yards sell for concrete, leveling and bedding, and mason sand is the finer clean sand for brick and block mortar and paver joints.

Where a surface needs to shed water instead of holding it, clean stone is the layer that does it:

• Drain Rock for French drains, drywells, foundation drains and downspout runs
• CA-7 for bedding under pipe and behind retaining walls
• 3/4" Crushed Stone for drainage and concrete work
• CA-16 Chips, the 3/8 inch limestone chips, for permeable paver bedding and drainage around tanks

For the surface itself, Lime Screenings bed pavers and flagstone and backfill around pipe. CA-6 is the base course under all of it.

Delivery to Aurora and the Surrounding Area

Quantities are ordered by the ton or by the yard, depending on the material. Each product page has a calculator, and that is the place to size your load before you check out.

You order online, pick a delivery date at checkout, and a dump truck tips the load on site in one pile. The material lands where the truck can reach, so it helps to know where you want that pile before the truck arrives.

Illinois Rock Supply delivers across Aurora and Kane County, including Elgin, Dundee, Carpentersville, St. Charles and Batavia.

Give the delivery address and the load size, and the rest is scheduling.

Questions About Gravel and Aggregate in Aurora

What gravel is best for a driveway in Aurora?

CA-6, also called CA6 or road base, is the standard choice here. It is dense graded crushed limestone with the fines left in, so it compacts into a firm surface for a drive or parking pad.

For topping an existing drive, Driveway Gravel covers the same job.
