Buy CA-11 in Northbrook, IL

Illinois Rock Supply handles gravel and aggregate delivery in Northbrook, IL, from single residential loads to contractor quantities. CA-6, the dense graded crushed limestone with the fines left in, is the base this area builds on.

The ground across the Chicago lake plain and the northeastern moraines sheds water instead of taking it, so what you put down and how it drains both matter. Order online by the ton or the yard.

Materials for Northbrook Projects

Base and driveway work starts with CA-6, also called road base or 3/4 dense grade. It is dense graded crushed limestone with the fines left in.

It goes under driveways, parking pads, shed and garage bases and trench backfill. Driveway surfacing on an existing drive or a compacted base uses Driveway Gravel or Crusher Run.

Washed stone carries water instead of holding it. CA-7 is the 1 inch clean stone.

3/4" Crushed Stone, sold as CA-11 or CA 11 by number, is the 3/4 inch clean washed stone for bedding, drainage and concrete work. Lime Screenings bed pavers and flagstone.

Sand and soil finish the job. Washed Sand is torpedo sand, the coarse washed sand for concrete and leveling, and Top Soil is screened Illinois prairie soil for lawns and bed prep.

Ground and Conditions in Northbrook

Water is the driver here. Across the Chicago lake plain and the northeastern moraines, heavy silt and clay shed rain and snowmelt rather than absorb it, and the flat ground gives that water little fall.

Summer downpours overwhelm yard grades and storm sewers, so a drainage layer under the surface matters as much as the surface itself. CA-7 and CA-11 are the washed materials for that work.

Bare clay lots sheet wash after heavy rain, and a fines-bearing base sitting in standing water will not hold. That is the case for clean stone under a drain run and a compacted CA-6 course above it.

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 until it drains.

Long cold winters bring many freeze and thaw cycles, and frost lifts drives, walks and slabs every spring. Northeastern Illinois jurisdictions carry a frost depth of about 42 inches in the residential code, and the local building department sets the figure.
