CA-6, Sand and Gravel Delivery in Kane County, IL
Illinois Rock Supply brings gravel, stone and aggregate delivery in Kane County, IL. Base, driveway and paver work here runs from the spring thaw into late fall.
Frozen ground stops compaction through the winter, and a wet spring keeps crews off soft clay.
CA-6 is the base material this state is built on. It is dense graded crushed limestone with the fines left in, and it goes under driveways, parking pads, shed and garage bases and trench backfill.
Ground Conditions Across Kane County
Across the Chicago lake plain and the northeastern moraines, the ground is heavy silt and clay over clay-rich till. Water sheds off that ground rather than soaking in, and flat ground has little fall to move it along.
When a base is too thin, the failure shows up as rutting, pumping and soft spots after a heavy rain. The clay holds the water underneath, and the surface stone works its way down into it.
A thick enough CA-6 course over a clean drainage layer is what keeps a drive or pad firm through a wet spring. Heavy summer downpours overwhelm yard grades and storm sewers in the older built-up areas, so drainage has to move water somewhere.
Erosion is a real driver on this ground. Stream bank scour follows heavy rain, and bare clay lots sheet wash before anything is planted or paved.
Riprap armors banks, culvert outlets and pond edges.
Winters here run long and cold with many freeze and thaw cycles. Frost lifts drives, walks and slabs every spring and leaves gravel surfaces soft until the ground drains.
Frost depth is about 42 inches, the figure northeastern Illinois jurisdictions carry in the residential code; the local building department sets it.
Materials Delivered in Kane County
Article 1004.01 sets the coarse aggregate gradations CA 1 through CA 20, and Article 1005.01 sets the riprap gradations RR 3 through RR 7.
Those numbers are how material is specified and ordered in Illinois.
CA-6 is the Illinois base material: dense graded crushed limestone with the fines left in.
Chicago area yards also call it grade 8, grade 9 or road mix.
Clean washed stone has no fines and does not compact into a base. CA-7 is the 1 inch clean stone for bedding under pipe, drainage trenches, French drains and concrete flatwork.
CA-11 is the 3/4 inch clean washed stone that Illinois yards sell alongside CA-7 for bedding, drainage and concrete work.
CA-16 Chips are 3/8 inch chips for permeable paver bedding, drainage around tanks and topping a compacted base.
Lime Screenings are crushed limestone fines for paver and flagstone bedding and for backfill around pipe. Screenings are the standard bedding layer in Illinois.
Washed Sand, which Illinois yards call torpedo sand, is coarse washed sand for concrete, leveling and bedding. Mason Sand is the finer clean sand for brick and block mortar, paver joints, sandboxes and volleyball courts.
RipRap is heavy broken stone for bank protection, culvert outlets, pond edges and slope armoring.
Top Soil covers lawns, grading and bed prep. Illinois prairie topsoil is dark and silty, and yards sell it screened.
Fill Dirt raises grade before a CA-6 base course goes down.
Delivery Across Kane County
You order online and choose a quantity by the ton or by the yard. Each product page has a calculator to help size the load.
You pick a delivery date at checkout, and a dump truck tips the material on site in one pile.
Delivery covers Aurora, Elgin, Dundee, Carpentersville, St. Charles, Batavia, South Elgin, Geneva, North Aurora, Sugar Grove, Gilberts, Hampshire, Elburn and Big Rock.
Bulk loads are heavy and the truck needs room to reach the drop point and turn around. Have the area clear before the truck arrives, and know where the pile should sit.
Choosing the Right Material
DeKalb County sits in Northern Illinois, on till plains and Rock River country. That ground is Wisconsin Episode till and loamy prairie soils over dolomite, broken by sand and gravel in the Green River Lowland and by rocky hill country.
It differs from the lake plain and moraine clay here, so a base course there sits on better draining soil.
Cook County and DuPage County share Kane County's ground region: the Chicago lake plain and the northeastern moraines. The same heavy silt and clay, the same clay-rich till, and the same shallow dolomite in places.
Base and drainage choices carry over between them.
On clay ground, separate the layers. Use clean stone such as CA-7 or CA-11 where water has to pass through, and keep fines-bearing CA-6 for the compacted base itself.
Questions About Ordering Aggregate in Kane County
Should I order material by the ton or by the yard?
Both work, and the product pages let you choose either. The calculator on each product page helps you size the load.
Ordering by the ton is common for stone and gravel, while soil, sand and mulch are often ordered by the yard. Pick the unit that matches how you measured the area.
Which stone is best for drainage in Kane County?
Use clean washed stone that has no fines. CA-7 and CA-11 are the Illinois gradations for bedding, French drains, foundation drains and downspout runs.
CA-16 chips suit tighter bedding and drainage around tanks. Fines-bearing CA-6 is a base material and holds water rather than passing it.
What do I need to have ready for a bulk delivery?
Have the drop area clear and reachable by a dump truck, with room to turn around. The truck tips the load in one pile, so decide where that pile should sit before it arrives.
