Rip Rap and Bulk Aggregates for Itasca, IL

Illinois Rock Supply brings gravel and aggregate delivery in Itasca, IL to driveways, drainage projects and yards. The base material here is CA-6, also called road base, a dense graded crushed limestone with the fines left in.

Itasca sits in DuPage County on the Chicago lake plain and the northeastern moraines, where heavy silt and clay shed water instead of taking it. That shapes what you order and where you put it.

Materials for Itasca Projects

Coarse stone does the heavy work on slopes, swales and banks here. On clay ground with little fall, water moves along the surface, so the stone that armors an edge matters as much as the pipe that carries it away.

RipRap is the heavy 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.

Below that size, CA-7 is washed clean stone with no fines, for bedding under pipe, drainage trenches, French drains and concrete flatwork. 3/4" Crushed Stone, sold as CA-11, is the 3/4 inch clean washed stone that pairs with it.

CA-16 Chips are the small 3/8 inch chips for permeable paver bedding, drainage around tanks and topping a compacted base. CA-16 Chips sit at the fine end of clean stone.

When the work needs a surface that holds together, CA-6 is the Illinois base material: dense graded crushed limestone with the fines left in, for driveways, parking pads, shed and garage bases and trench backfill.

Ground and Conditions in Itasca

Base, driveway and paver work runs from the spring thaw into late fall. Frozen ground stops compaction through the winter, and a wet spring keeps crews off soft clay.

Across the Chicago lake plain and the northeastern moraines, clay and dense till shed water rather than take it. Flat ground has little fall, so heavy summer downpours overwhelm yard grades and storm sewers.

That is why a drainage layer and coarse stone at the low edge matter more than a thicker base in many yards. Clean stone moves water; fines-bearing material does not.

Frost lifts drives, walks and slabs every spring and leaves gravel surfaces soft until the ground drains. Northeastern Illinois jurisdictions carry a frost depth of about 42 inches in the residential code, and the local building department sets that figure for its own area.
