CA-6 and Bulk Aggregates for Prospect Heights, IL

If you are pricing gravel and aggregate delivery in Prospect Heights, IL, the first question is usually which stone the job actually needs. Illinois Rock Supply sells bulk material by the ton and delivers it to your site.

CA-6, also called road base, is the dense graded crushed limestone with the fines left in. It is the base material for driveways, parking pads, shed and garage bases and trench backfill.

Clay ground under a wet spring is the other half of the decision.

Water is the reason clean washed stone matters here. Lake plain clay and dense till shed water instead of taking it, so drainage stone has to stay open and free of fines.

CA-7, also called #57 stone or 1 inch clean stone, is washed clean with no fines. It beds pipe, lines drainage trenches and French drains, and sits under concrete flatwork.

CA-11, also called 3/4 inch clean stone or sewer stone, is the 3/4 inch washed stone sold alongside CA-7. It does the same bedding, drainage and concrete work at a smaller size.

CA-16 chips, also called 3/8 inch limestone chips, are small chips for permeable paver bedding and drainage around tanks. They also top a compacted base.

For drywells and downspout runs, clean stone is what lets water move instead of ponding. Drain Rock covers French drains, drywells, foundation drains and downspout runs, and Illinois contractors specify the same work as CA-7 or CA-11 by number.

Rip rap, also called riprap or RR3 and RR4, is heavy broken stone for bank protection, culvert outlets, pond edges and slope armoring.

On the fine end, Lime Screenings are crushed limestone fines for paver and flagstone bedding and for backfill around pipe. They are the standard bedding layer in Illinois.

Torpedo sand, also called concrete sand or washed 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.

For a base course under any of it, CA-6 is the Illinois name. Crusher Run is the same idea of crushed stone with the fines left in under a secondary name.

Ground and Conditions in Prospect Heights

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, the ground is heavy silt and clay close to the lake and clay-rich till inland. That ground sheds water rather than taking it, and flat lots have little fall.

Heavy summer downpours overwhelm yard grades and storm sewers in the older built-up areas. Sheet wash off bare clay lots is the other problem, which is why a compacted CA-6 surface and open drainage stone go down together.

Long cold winters with many freeze and thaw cycles lift drives, walks and slabs every spring. Gravel surfaces stay soft until the ground drains.

Frost depth is about 42 inches in northeastern Illinois, the figure jurisdictions there carry in the residential code, and the local building department sets it.
