Order CA-6 and Crushed Stone in Knox County, IL
If you are pricing gravel, stone and aggregate delivery in Knox County, IL for a drive, a pad or a drain, the answer starts with CA-6. Illinois Rock Supply sells CA-6, clean stone, sand, topsoil and fill by the ton, delivered in a dump truck.
CA-6 is dense graded crushed limestone with the fines left in. It is the base material this state specifies by number, and in this part of the Western Illinois loess uplands and the Mississippi border it goes down over deep, silty ground.
Ground Conditions Across Knox County
This part of the state sits on deep loess over older drift, on rolling uplands cut by steep ravines. Loess sheds water fast on a slope and holds it in the flats.
That matters under a drive. Water that sits in silty ground softens it, and a base built thin over soft ground moves.
CA-6 packs into a tight, load-bearing layer because the fines bind the stone together.
Gully and rill erosion are the other local problem on steep ground. Where runoff concentrates, a slope cuts back quickly, and rip rap armors a bank or a culvert outlet before it does.
Work runs from the spring thaw into late fall here, a little longer than upstate. Frost still lifts drives and walks each spring, and the local building department sets the footing depth at about 36 to 40 inches.
Materials Delivered in Knox County
Lead with the job. A driveway, a patio, a drain and a garden bed each take a different material, and the local names below are what Illinois yards sell.
CA-6 carries the most weight on a Knox County job, because it is the layer everything else sits on.
Around a house, CA-7 and CA-11 handle anything that has to drain. Both are washed clean, so water moves through instead of sitting against a foundation.
Use lime screenings where a paver or flagstone needs a smooth bedding layer.
Choosing the Right Material
Knox County sits on loess uplands, and two of the counties next to it sit on ground that behaves differently. Peoria County spans more than one zone, taking in the Grand Prairie till plain and the Illinois River valley and its sand areas.
Henry County runs to Northern Illinois till plains and Rock River country, over dolomite.
Stark County shares the Grand Prairie till plain that Knox County's uplands also fall under, so the ground there is much the same. Where a neighbour's ground differs, the change is in what sits under the base.
A till plain drains differently from loess, and sand and gravel ground drains differently again. On a sandy or gravelly subgrade, water leaves quickly and a base course still has to bridge the soft spots.
On loess, the silty ground holds moisture in the flats and sheds it on the slopes.

What is the difference between crushed stone and Natural Pea Gravel?
Crushed stone is angular and broken, and it comes in numbered sizes. CA-6 has fines left in so it compacts into a base, while CA-7 and CA-11 are washed clean for drainage.
Natural Pea Gravel is rounded 3/8 inch washed gravel, sold here as 3/8" Natural Pea Gravel, for walkways, play areas and drainage.
