Buy CA-11 in Tinley Park, IL

Planning gravel and aggregate delivery in Tinley Park, IL usually starts with one job: a driveway rebuild, a patio base, or a drainage run alongside the house. Illinois Rock Supply sells the material for all three, ordered online and tipped on site.

Most of that work starts with CA-6, the dense graded crushed limestone Illinois crews call road base. Around here the heavy silt and clay under the topsoil decides how the rest of the job goes.

Materials for Tinley Park Projects

Base and driveway surfacing carry most residential work in this market. CA-6, also called CA6 or 3/4 dense grade, is dense graded crushed limestone with the fines left in.

It builds up a driveway, a parking pad, a shed or garage base, and trench backfill.

Some Chicago area yards still call the same material grade 8 or road mix. It is the same stone.

Order it as CA-6 and you get the fines-bearing base that tightens up under a vehicle.

Washed stone is the other half of the list. CA-7, sold elsewhere as #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 is the 3/4 inch clean washed stone that goes with it, for bedding, drainage and concrete work. Order 3/4" Crushed Stone and you are getting the CA-11 gradation.

CA-16 chips are the 3/8 inch size, for permeable paver bedding and drainage around tanks.

Sand and soil finish the order. Torpedo sand, the coarse washed sand Illinois yards sell, goes into concrete and leveling.

Washed Sand is the same material. Lime screenings bed pavers and flagstone.

Top Soil handles lawns, grading and bed prep.

Ground and Conditions in Tinley Park

Water is what decides how a job here gets built. The clay and dense till across this part of the Chicago lake plain and the northeastern moraines shed water rather than take it.

Flat ground leaves little fall, so heavy summer rain backs up on yard grades instead of running off. Snowmelt in spring does the same thing.

A drainage run needs clean washed stone, not a fines-bearing base that holds water.

That is where CA-7 and CA-11 come in, along with Drain Rock for French drains, drywells and downspout runs. Clay-rich till and silt also mean bare lots wash, so cover goes down before the surface moves.

The working season 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 repeated freeze and thaw cycles, which lift drives and slabs every spring.

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

Footing depth follows that number, not base depth for a driveway.
