CA-6, Sand and Gravel Delivery in Hamilton County, IL
Illinois Rock Supply brings gravel, stone and aggregate delivery in Hamilton County, IL to McLeansboro, Dahlgren, Broughton and the surrounding towns. Start with CA-6, the dense graded crushed limestone that carries the fines and builds the base under a drive, a pad or a shed floor.
Across the Southern till plain and claypan country, water sits on tight subsoil and softens whatever you put on top of it. CA-6 gives you a compactable surface that stands up to that ground.

Materials delivered in Hamilton County
Match the material to the job. A drive, a drain and a patio bed each call for something different, and the local names below are what you use to order.
CA-6 is the Illinois base material. It is dense graded crushed limestone with the fines left in, and it is how aggregate is specified in this state.
Order CA-6 for a driveway, a parking pad, a shed or garage base, or trench backfill. For clean stone with no fines, order CA-7 or CA-11.
Sand, soil and decorative stone round out the list. Mason Sand handles brick and block mortar and paver joints, and River Gravel covers beds, borders and dry creek beds.
Ground conditions across Hamilton County
Across the Southern till plain and claypan country, loess sits over old, weathered Illinoian drift. The tight claypan subsoil close to the surface gives south central Illinois its reputation for hard, slow ground.
That claypan stops water moving down. Winter and spring rain perches on top of it, ground stays saturated for weeks, and unbound base pumps under traffic.
Sheet and gully erosion follows where the thin loess is bared. Bank scour works on valley banks, and flooding runs along the Wabash on the eastern edge of the region.
Plan around the season. The working window is longer than upstate at both ends, but a wet winter and spring keep sites soft well into April.
Late summer and fall are the reliable windows.
Winters are cold but shorter than in the north, with frequent freeze and thaw swings that work on saturated clay and heave drives and walks. Frost depth runs about 30 to 36 inches where a local building department sets it.
Choosing the right material
Franklin County shares Hamilton County's ground region, the Southern till plain and claypan country. The ground is the same, so the same base and drainage choices carry over.
Saline County and Gallatin County sit in the Shawnee Hills and the southern uplands. That is unglaciated hill country of sandstone and limestone, with thin soils and rock close to the surface.
On that hill ground, rock near the surface changes what a base course has to do. Steep wooded slopes and narrow valley bottoms with silt and gravel shift the choice toward drainage and slope protection.
Here on claypan ground, the base course carries the load over soft subsoil. There, the ground is shallower and steeper, so clean stone and riprap do more of the work.
