Crushed Stone, Sand and Gravel in Savanna, IL

Illinois Rock Supply handles gravel and aggregate delivery in Savanna, IL, and the working season here runs from the spring thaw into late fall. A wet spring is the hard part, when steep drives and hillside pads turn greasy.

CA-6, the dense graded crushed limestone with the fines left in, is the base material to start with.

Materials for Savanna Projects

Base and driveway surfacing come first on any drive, pad or shed floor. CA-6 is dense graded crushed limestone with the fines left in, and it packs into a firm surface for driveways, parking pads, garage bases and trench backfill.

Driveway Gravel surfaces an existing drive or tops a compacted base. Where a drive has gone soft or rutted, Crusher Run is the same idea as CA-6 under a secondary name.

Washed stone has no fines, so water moves through it. CA-7 is 1 inch clean stone for bedding under pipe, drainage trenches and French drains.

3/4" Crushed Stone is the CA-11 size sold alongside it for bedding, drainage and concrete work.

Sand and soil round out a site. Washed Sand is the coarse torpedo sand used for concrete, leveling and bedding.

Mason Sand is finer and clean, for brick and block mortar, paver joints and sandboxes. Top Soil is screened for lawns and grading, and Garden Soil fills raised beds and vegetable plots.

For decorative work, River Gravel is rounded stone for beds, borders and dry creek beds, and Large River Rock handles downspout splash areas and heavier decorative edges.

Ground and Conditions in Savanna

Across the Driftless and old-drift northwest, steep ground moves water fast into narrow valleys. Springs and seeps come out of the dolomite, and heavy rain runs off loess ridges before it can soak in.

That shapes what you put down and where.

On a slope, water needs somewhere to go. CA-7 or CA-11 in a trench gives it a path, and a CA-6 base holds its shape where the ground is cut and firm.

Rounded decorative stone does not lock together, so keep it off anything that has to carry a vehicle.

Erosion in this part of the state shows up as gully and rill cutting in loess on steep slopes. Cut banks slump and drop rock, and narrow valley streams scour.

Rip rap armors banks, culvert outlets and pond edges where moving water is the problem.

Frost works harder on thin soils over rock and on cut slopes. Frost depth in northern Illinois runs about 42 inches, and the local building department sets the figure that applies to your job.

Build to what your building official requires.

Delivery to Savanna and the Surrounding Area

You order online, choose a quantity by the ton or by the yard, and pick a delivery date at checkout. Each product page has a calculator if you want to size the load before you order.

A dump truck then tips the material on site in one pile.

Have the drop spot clear and reachable before the truck arrives. Bulk loads need room to back in and tip, and a steep or soft approach is the usual holdup on a hillside property.

Savanna sits in Carroll County, and delivery covers Mount Carroll, Lanark, Thomson, Milledgeville and Shannon as well.
