CA-11 and Bulk Aggregates for Smithfield, IL

Illinois Rock Supply handles gravel and aggregate delivery in Smithfield, IL. Across the Western Illinois loess uplands and the Mississippi border, loess sheds water fast on slopes and holds it in the flats.

That is a drainage problem before it is a driveway problem. CA-6, the local dense graded road base, sets the surface.

Clean washed stone moves the water.

Materials for Smithfield Projects

Washed stone handles water. French drains, drywells and downspout runs all need clean, open stone with no fines, so water passes through instead of sitting in it.

CA-7 is the 1 inch clean washed stone specified for bedding under pipe, drainage trenches and French drains. CA-7 also beds concrete flatwork.

The 3/4 inch clean washed size, CA-11, does the same work at a smaller grade. 3/4" Crushed Stone suits tight trenches.

For drywells, downspout runs and foundation drains, the size of the void matters. Bigger clean stone holds more open space, so a Drain Rock fill drains fast.

Where the soil is heavy and the trench is wide, larger clean stone helps. #4 Crushed Stone is the coarse clean option for trench bottoms and heavy drainage.

Fine washed stone closes the gap. CA-16 chips, the 3/8 inch limestone chips, bed permeable pavers and top a compacted base.

CA-16 Chips drain around tanks and tight spots.

Not every layer moves water. Some layers have to hold a load.

CA-6 is dense graded crushed limestone with the fines left in, and it compacts into a sturdy base for driveways, parking pads, shed and garage bases and trench backfill. CA-6 is the base material downstate yards sell by that name.

Grade 8 and grade 9 mean CA-6 in Chicago area yards only.

Sand and soil round out the order. Torpedo sand is the coarse washed sand for concrete, leveling and bedding.

Washed Sand sets level under pavers and flagstone. Lime screenings, the crushed limestone fines, bed pavers and flagstone and backfill around pipe.

Lime Screenings are the standard bedding layer in Illinois.

You order online. Choose a quantity by the ton or by the yard, and each product page has a calculator if you need to size the load.

Know where that pile lands before the truck arrives. On a narrow drive or a tight lot, the drop point decides how much work the rest of the job becomes.

Ground and Conditions in Smithfield

Work here runs from the spring thaw into late fall. That is a little longer than upstate, which helps when you are timing a delivery around a pour or a grade change.

The ground under this part of the state is deep loess over older drift, on rolling uplands cut by ravines. Loess sheds water fast on slopes and holds it in the flats.

Water that disappears into the ground instead of running to a ditch has to go somewhere.

So drainage gets built before the surface does. Clean washed stone under a downspout run or a French drain carries water away from a foundation or a drive edge.

A fines-bearing base like CA-6 sheds nothing, so keep it where the load goes and keep the clean stone where the water goes.

Frost still lifts drives and walks each spring. The frost depth in Illinois is about 36 to 40 inches, and the local building department sets the figure for footings.
