CA-6 and Bulk Aggregates for Montgomery, IL

Illinois Rock Supply provides gravel and aggregate delivery in Montgomery, IL, including CA-6, the dense graded crushed limestone this market calls road base. The ground here is heavy clay and silt, so it sheds water slowly and stays soft after a soaking.

That matters most under a driveway or a parking pad, where a compacted base is what keeps the surface from rutting. CA-6 is the base material for that work in Kendall County.

Materials for Montgomery Projects

Water is the hard part of a lot in this region. Clay and dense till push rain sideways instead of letting it sink, so drainage work has to move water to a low spot or a drywell rather than expect the soil to take it.

Washed stone is what that work is built from. Clean stone has no fines to pack tight, so water runs through the voids instead of sitting in the material.

Washed stone for drainage

CA-7 is 1 inch clean washed stone. It beds pipe, lines drainage trenches and French drains, and sits under concrete flatwork.

3/4" Crushed Stone, or CA-11, is the 3/4 inch clean washed stone sold alongside CA-7 for bedding, drainage and concrete work. Both sizes stay open to water.

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

Drain Rock covers the same ground for French drains, drywells, foundation drains and downspout runs. Contractors here are as likely to specify CA-7 or CA-11 by number.

Base, bedding and surface material

CA-6 is dense graded crushed limestone with the fines left in. It compacts into a firm base for driveways, parking pads, shed and garage floors, and trench backfill.

Lime Screenings are the crushed limestone fines used to bed pavers and flagstone and to backfill around pipe. They are the standard bedding layer in Illinois.

Washed Sand, called torpedo sand here, is the coarse washed sand for concrete, leveling and bedding. Mason Sand is the finer clean sand for brick and block mortar and paver joints.

A dump truck tips the load on site in one pile, so the drop spot needs to be somewhere the truck can reach and the pile can sit while you work from it.

Ground and Conditions in Montgomery

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.

Timing a delivery around that window matters. Ground that has drained and warmed compacts far better than ground still holding winter moisture.

Across the Chicago lake plain and the northeastern moraines, heavy summer downpours overwhelm yard grades and storm sewers, and sheet wash moves bare clay off graded lots. A drainage layer of clean stone gives that water somewhere to go.

Frost is the other factor. Long cold winters with many freeze and thaw cycles lift drives, walks and slabs every spring and leave gravel surfaces soft until the ground drains.

Frost depth is set by the local building department.
