Bulk Aggregates for Patios in Bartlett, IL

If you are planning a patio, a driveway or a drainage run in Bartlett, IL, the material list starts with gravel and aggregate delivery in Bartlett, IL from Illinois Rock Supply. CA-6, also called road base, is the dense graded crushed limestone most of that work starts on.

Bartlett sits in DuPage County, on the clay-rich till of the northeastern moraines, where ground sheds water instead of taking it. That shapes what goes under a patio as much as what goes on top.

Ground and Conditions in Bartlett

Across the Chicago lake plain and the northeastern moraines, the soil is heavy silt and clay over dense till. Water runs off rather than soaking in, and flat ground gives it little fall.

When a base course under pavers or flatwork is too thin, that water has nowhere to go. The slab or paver field rocks and settles the first spring after a wet winter.

The fix is a base that handles water: a compacted fines-bearing course for structure, with clean washed stone where drainage has to move. Clay lots that sit bare also sheet-wash, so covering ground early helps.

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

Materials for Bartlett Projects

Under a patio, the base does the work. CA-6 is the Illinois base material: dense graded crushed limestone with the fines left in.

It goes under driveways, parking pads, shed and garage bases and trench backfill.

Around Chicago, yards also call that same material grade 8 or grade 9, or road mix. It is one product, not two, and grade 8 is not the same as #8 crushed stone.

Bedding is where the finish lives. Lime Screenings are the crushed limestone fines used for paver and flagstone bedding and for backfill around pipe, and they are the standard bedding layer in Illinois.

Where water has to drain instead of sit, switch to clean washed stone. 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 goes alongside it for bedding, drainage and concrete work.

For tight bedding, CA-16 Chips are the 3/8 inch limestone chips for permeable paver bedding, drainage around tanks and topping a compacted base.

Concrete and leveling take sand, and Illinois yards call coarse washed sand torpedo sand. Washed Sand is that material, for concrete, leveling and bedding, while Mason Sand is the finer clean sand for brick and block mortar, paver joints, sandboxes and volleyball courts.
