CA-11, Stone and Soil Delivery in Schiller Park, IL

Illinois Rock Supply handles gravel and aggregate delivery in Schiller Park, IL. CA-6, also called road base, is the dense graded crushed limestone that most base work in this market starts from.

Around here the ground is heavy silt and clay, laid down on the old Lake Chicago lake plain and in the clay-rich moraines inland. That ground sheds water rather than takes it, so base depth and drainage both matter.

Materials for Schiller Park Projects

Water is the problem this ground hands you. Lake plain clay and dense till shed storm water instead of absorbing it, flat lots have little fall, and heavy summer downpours overwhelm yard grades.

Washed stone is what moves that water away.

Washed stone carries no fines, so water runs through it instead of pooling.

CA-7 is the 1 inch clean stone, also sold as #57 stone. It beds pipe, fills drainage trenches and French drains, and sits under concrete flatwork.

CA-11 is the 3/4 inch clean washed stone, sometimes called sewer stone. It does the same jobs as CA-7 at a smaller size, which suits tighter trenches and downspout runs.

CA-16 Chips are 3/8 inch chips. They bed permeable pavers, drain around tanks, and top a compacted base.

#4 Crushed Stone is the largest clean size, close to the CA-5 gradation. It suits construction entrances, heavy drainage and trench bottoms.

Where you need a base rather than a drain, CA-6 is the dense graded limestone with the fines left in. It builds driveways, parking pads, shed and garage bases and trench backfill.

For bedding and finer finishes, lime screenings are the Illinois name for screenings. They bed pavers and flagstone and backfill around pipe.

Torpedo sand is the coarse washed sand used for concrete and leveling.

Ground and Conditions in Schiller Park

Timing decides more jobs here than material choice does. 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.

Freeze and thaw cycles lift drives, walks and slabs every spring and leave gravel surfaces soft until the ground drains. Northeastern Illinois jurisdictions carry a frost depth of about 42 inches in the residential code; the local building department sets it, and it is a footing depth rather than a digging target.

Clay also erodes. Sheet wash moves bare ground after heavy rain, so exposed lots want cover sooner rather than later.

Plan the delivery around the season, not just the schedule.
