Order CA-6 and Crushed Stone in Gallatin County, IL
Illinois Rock Supply delivers gravel, stone and aggregate delivery in Gallatin County, IL, ordered online and tipped on site. CA-6, the dense graded crushed limestone with the fines left in, is the base material most of this ground gets built on.
Across the Shawnee Hills and the southern uplands, the soil sits thin over sandstone and limestone, and rock is often close to the surface. That shallow ground decides how much base a drive or pad really needs.
Ground Conditions Across Gallatin County
This is unglaciated hill country. Thin soil over rock, loess on the ridge tops, steep wooded slopes and narrow valley bottoms filled with silt and gravel.
Thin soil over rock has nowhere to store water. When heavy rain arrives from the Gulf, runoff concentrates fast into the narrow hollows between the ridges.
That runoff scours hillside drives and culvert outlets. It gullies steep unsurfaced tracks and slumps cut banks, and it flash floods the hollows below.
Because of that, a base built too thin on a slope will not hold. Water reaches the subgrade before the stone does, and the surface starts to move.
Working conditions here are the longest season in Illinois, running from late winter into early winter. Wet weather and soft hillside access set the schedule more than frozen ground does.
Winters are the mildest in the state, but regular freeze and thaw still works on exposed ground. On these slopes, water matters more than frost.
Materials Delivered in Gallatin County
CA-6 carries the most weight on a hillside job. It is dense graded crushed limestone, which means the fines stay in and the stone knits into a firm, tight surface.
Article 1004.01 sets the coarse aggregate gradations CA 1 through CA 20, so dense graded base is CA-6.
Order CA-6 for a driveway, a parking pad, a shed or garage base, or trench backfill. On steeper ground it goes over fill that has already been placed and shaped.
For a patio, order the bedding layer, not the base. Lime screenings bed pavers and flagstone, and CA-16 chips handle permeable paver bedding.
For a drain, the stone has to be clean. CA-7 and CA-11 are washed with no fines, so water moves through instead of sitting in the trench.
Choosing the Right Material
Gallatin County sits in the Shawnee Hills and the southern uplands, the unglaciated hill country of sandstone and limestone.
Saline County shares that same ground region, so the base and drainage choices run along the same lines. There is no meaningful difference to work around between the two.
White County and Hamilton County sit on southern till plain and claypan country. That is loess over old, weathered Illinoian drift, with a tight claypan subsoil and flatter relief.
That claypan changes the drainage picture. Ground there holds water instead of shedding it down a hollow, so a base has to deal with a slow, perched water table rather than fast runoff.
On Gallatin County slopes, the opposite problem applies. Water leaves quickly and takes fine material with it, so clean stone and proper outlet protection matter more.
