Bulk Gravel and Stone Delivery in Johnson County, IL
Illinois Rock Supply delivers gravel, stone and aggregate in Johnson County, IL, from Vienna and Goreville to Buncombe, Cypress, New Burnside, Belknap, Simpson, Boles, Grantsburg and Ozark. The base material here is CA-6, also called road base, the dense graded crushed limestone with the fines left in.
That is the starting point for most ground work on these hills, where soil sits thin over sandstone and limestone.
Materials Delivered in Johnson County
CA-6 is the Illinois base material. It is dense graded crushed limestone with the fines left in.
It goes down under driveways, parking pads, shed and garage bases, and trench backfill.
Clean stone is specified by number in Illinois, and the number tells you what the stone does. CA-7 is washed 1 inch stone with no fines, for bedding under pipe, drainage trenches, French drains and concrete flatwork.
CA-11 is the 3/4 inch clean washed stone sold alongside it for the same bedding and drainage work.
Smaller clean sizes handle tighter jobs. CA-16 Chips are 3/8 inch chips for permeable paver bedding and drainage around tanks.
Lime Screenings are crushed limestone fines for paver and flagstone bedding and backfill around pipe.
Sand covers concrete and mortar work. Torpedo Sand is coarse washed sand for concrete, leveling and bedding.
Mason Sand is finer and clean, for brick and block mortar, paver joints, sandboxes and volleyball courts.
For banks and slopes, RipRap is heavy broken stone for bank protection, culvert outlets, pond edges and slope armoring.
Ground cover rounds out an order. Top Soil is screened Illinois prairie topsoil for lawns, grading and bed prep.
Fill Dirt raises grade before a CA-6 base course goes down. Shredded Mulch holds moisture in beds and tree rings through an Illinois summer.
Choosing the Right Material
Johnson County sits in the Shawnee Hills and the southern uplands, where the ground is unglaciated hill country of sandstone and limestone with thin soils and rock close to the surface. Williamson County shares that same ground region, so the material choices there follow the same logic as here.
Massac County and Pulaski County sit in the Cairo lowland and the southern river bottoms, which is flat alluvial bottomland with deep silt, sand and clay laid down by the rivers and a high water table under most of it. That is a different set of problems from thin soil over rock.
On deep silt and clay with a high water table, water has nowhere to go and the ground stays soft. A clean washed stone like CA-7 or CA-11 gives water a path, and a fines-bearing base like CA-6 needs the drainage handled first.
On hillside ground, the thin soil and shallow rock matter more than the water table. Cut banks slump, and runoff scours whatever surface it crosses, so slope protection and outlet stone carry more weight here.
Ground Conditions Across Johnson County
Across the Shawnee Hills and the southern uplands, steep ground concentrates runoff into narrow hollows very quickly. Thin soil over rock has nowhere to store water, and heavy rain from Gulf moisture arrives in large amounts at once.
That combination scours hillside drives and culvert outlets, gullies steep unsurfaced tracks, and drives flash flooding in the hollows. Rock fall and slumping on cut banks follow the same pattern.
The practical answer is a base that sheds water rather than holding it, with clean stone at outlets and along drainage runs. Where a base sits on thin soil over rock, the fines in a dense graded material can hold water against the rock and soften the layer above it.
The working season here is the longest in Illinois, running from late winter into early winter. Wet weather and soft hillside access set the limit rather than frozen ground.
Winters are the mildest in the state, but freeze and thaw still come regularly. Frost depth is about 30 inches in the far southern counties, and the local building department sets the figure that applies to a given job.
Delivery Across Johnson County
You order online and a dump truck tips the load on site. Quantities are ordered by the ton or by the yard, and each product page has a calculator for sizing the load before you check out.
Delivery covers Vienna, Goreville, Buncombe, Cypress, New Burnside, Belknap, Simpson, Boles, Grantsburg and Ozark, along with the rest of the county. Pick a delivery date at checkout and the truck arrives with the material.
On hillside ground, think about where the pile can sit before the truck gets there. A load tipped on a steep drive or a soft shoulder can be hard to work from, and a narrow hollow road leaves little room to turn around.
