Start with CA-6, the dense graded crushed limestone this market calls road base. It carries the fines that bind a base together, and it sits under most paver patios and flatwork here.

Ground and Conditions in Oak Lawn

Across the Chicago lake plain and the northeastern moraines, the ground is heavy silt and clay over dense till. It sheds water instead of taking it, and flat lots leave little fall for runoff.

A thin base shows that failure fast. Water sits, the subgrade softens, and the pavers above start to rock and dip.

Fix it with a base that drains and a subgrade that stays put. Open, clean stone lets water pass; fines-bearing stone placed wrong traps it.

Winter works against you too. Many freeze and thaw cycles lift drives, walks and slabs every spring.

Frost depth in northeastern Illinois runs about 42 inches, the figure local jurisdictions carry in the residential code, and the local building department sets it. That number is a footing depth, not a digging instruction.

Timing matters as much as material. 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 until it drains.

Materials for Oak Lawn Projects

Most patio and flatwork jobs here come down to what goes under the surface. Bedding and base layers decide whether the finished work stays flat.

CA-6 is the base course: dense graded crushed limestone with the fines left in. Use it for driveway and parking pad bases, shed and garage pads, and trench backfill.

Lime Screenings, also called limestone screenings, are the standard bedding layer in Illinois. The crushed limestone fines set pavers and flagstone flat and fill around pipe.

CA-7 is washed clean stone with no fines. Bed pipe on it, run drainage trenches and French drains with it, and place it under concrete flatwork.

3/4" Crushed Stone, sold locally as CA-11, does the same work at 3/4 inch.

For tighter work, CA-16 Chips are 3/8 inch chips for permeable paver bedding and drainage around tanks. Washed Sand, which this market calls torpedo sand, is coarse washed sand for concrete and leveling.
