Buy CA-11 in Dupo, IL

Illinois Rock Supply handles gravel and aggregate delivery in Dupo, IL for two kinds of buyers: contractors working the Metro East and homeowners finishing a drive or a bed. Most ground here is deep loess over older drift, so what sits under a drive matters as much as what you put on top.

CA-6, the dense graded crushed limestone with the fines left in, is the base material that carries driveways, parking pads and shed floors in this market. From there you build up or out with washed stone, sand, soil or decorative rock.

Materials for Dupo Projects

Base and driveway surfacing is where most Dupo projects start, and CA-6 is the material that does that work.

The fines bind the crushed limestone together so it knits into a firm surface under a drive or a pad.

For an existing drive that just needs a fresh surface, Driveway Gravel tops a compacted base. Crusher Run is the same idea under a secondary name, crushed stone with the fines still in it.

Washed stone handles everything that has to drain. CA-7 is clean 1 inch stone with no fines, used for bedding under pipe, drainage trenches and French drains.

3/4" Crushed Stone, sold as CA-11, is the 3/4 inch clean washed stone that goes alongside it for bedding, drainage and concrete flatwork.

Smaller clean sizes finish tight work. CA-16 Chips are 3/8 inch chips for permeable paver bedding and drainage around tanks.

Lime Screenings are the crushed limestone fines that bed pavers and flagstone and backfill around pipe.

Sand and soil round out a project. Washed Sand, which Illinois yards call torpedo sand, is the coarse washed sand for concrete, leveling and bedding.

Mason Sand is finer and clean, for brick and block mortar, paver joints and sandboxes.

On the decorative side, 3/8" Natural Pea Gravel is rounded washed gravel for walkways, play areas and drainage, and River Gravel is the rounded stone for beds, borders and dry creek beds.

Ground and Conditions in Dupo

Start with where the water goes, because that decides what you put down. Across the Western Illinois loess uplands and the Mississippi border, loess sheds water fast on slopes and holds it in the flats.

Bottomland sites behind the levees drain slowly.

On a slope, that fast runoff cuts gullies and rills into loess and slumps cut faces. On flat ground, the same silty soil holds moisture and stays soft.

A drive on either one needs a base that will not pump or rut when it is wet.

That is the argument for CA-6 under a drive rather than clean stone. The fines in CA-6 let it compact into a tight, load-bearing layer.

Clean washed stone like CA-7 or CA-11 has no fines, so it stays loose and open, which is exactly what you want in a drainage trench and not what you want under a tire.

Where runoff concentrates, water can disappear into the ground instead of running to a ditch, and that is a drainage problem rather than a surface one. Clean stone in a trench or a drywell gives that water somewhere to go.

Work runs from the spring thaw into late fall here, a little longer than upstate, and bottomland sites wait out spring high water. Frost still lifts drives and walks each spring.

Where a frost depth figure is needed, the local building department sets it.
