Bulk Material Delivery in Rock City, IL

Illinois Rock Supply handles gravel and aggregate delivery in Rock City, IL, and the material base work here still starts with CA-6. That is dense graded crushed limestone with the fines left in, the same thing area yards also call road base or 3/4 dense grade.

This corner of the state sits on Driftless and old-drift northwest ground: thin soil on the ridges, rock close to the surface, and water that runs off fast. Each product page has a calculator, so you can size a load before ordering.

Materials for Rock City Projects

Coarse stone does the heavy work on slopes, swales and banks in this part of Stephenson County. When water leaves a hillside in a hurry, the stone at the bottom of the run is what keeps the ground where it is.

RipRap is broken stone for bank protection, culvert outlets, pond edges and slope armoring.

#4 Crushed Stone is a large clean stone for construction entrances, heavy drainage and trench bottoms.

Nothing in it holds water, which is the point on a wet slope.

CA-7 is washed clean stone with no fines, used for bedding under pipe and in drainage trenches. 3/4" Crushed Stone, sold as CA-11, is the 3/4 inch clean washed stone that goes with it on concrete flatwork.

CA-6 is the compacted base under driveways, parking pads, shed floors and garage slabs. Use it where you need a surface that binds, not one that drains.

For a drive that only needs topping, Driveway Gravel is the surfacing choice.

Finer material has its own jobs. Lime Screenings bed pavers and flagstone and backfill around pipe.

Washed Sand, which yards here call torpedo sand, is the coarse washed sand for concrete and leveling.

Delivery to Rock City and the Surrounding Area

You order online, choose a quantity by the ton or by the yard, and pick a delivery date at checkout. A dump truck then tips the load on site.

That is the whole of it.

Delivery covers Rock City and the rest of Stephenson County, including Freeport, Lena, Orangeville, Pearl City and Kent. If your site is inside that area, it can be scheduled the same way as any other address.

Bulk loads are heavy and the truck needs room to reach the drop point and leave. On a narrow valley road or a long drive, the pile lands where the truck can safely tip it.

Ground and Conditions in Rock City

Work here runs from the spring thaw into late fall. A wet spring is the hard part, because the loess on steep ground turns greasy and a loaded truck fights for traction.

Across the Driftless and old-drift northwest, steep ground moves water fast into narrow valleys, and heavy rain runs off the ridges before it can soak in. Seeps come out of the dolomite, so water shows up where the ground looks dry.

That shapes what you put down. A swale or bank that has to shed water wants clean open stone such as CA-7 or CA-11, because fines in a base material hold moisture and move with it.

Erosion on these slopes shows up as gullies in the loess and slumping on cut banks. Armoring those spots with coarse stone early is easier than rebuilding a bank after a season of runoff.

Frost works harder where soil is thin over rock than it does on deep ground. Any frost depth for a footing comes from the local building department, so check with them before you plan that work.
