Crushed Stone, Sand and Gravel in Palos Hills, IL

If you are planning gravel and aggregate delivery in Palos Hills, IL, the job usually starts with what the surface sits on. A driveway, a parking pad or a shed base takes CA-6, the dense graded crushed limestone Illinois yards call road base.

Illinois Rock Supply sells that base material and the rest of the bulk list online. Palos Hills sits on heavy clay soil, so what you put under a drive matters as much as what you see.

Materials for Palos Hills Projects

CA-6 is the Illinois base course, dense graded crushed limestone with the fines left in. It goes under driveways, parking pads, garage and shed slabs, and trench backfill.

Chicago area yards also call this grade 8 or grade 9.

For an existing drive that just needs a new wearing surface, driveway gravel is the surfacing layer. crusher run is crushed stone with the fines left in, the secondary name for the same idea.

Washed stone is the other half of the work. CA-7 is 1 inch clean stone, and 3/4" Crushed Stone is CA-11.

Both are washed clean with no fines, so water moves through them. They bed pipe, line drainage trenches and French drains, and sit under concrete flatwork.

Smaller clean sizes handle tighter work. CA-16 Chips are 3/8 inch chips for permeable paver bedding and drainage around tanks.

Lime Screenings are the crushed limestone fines Illinois crews bed pavers and flagstone on.

Sand comes in two grades. Washed Sand is torpedo sand, coarse and washed, for concrete and leveling.

Mason Sand is finer and cleaner, for brick and block mortar, paver joints and sandboxes.

For soil and finish work, Top Soil is screened Illinois prairie topsoil, dark and silty, for lawns and bed prep. Garden Soil fills raised beds and vegetable plots, and Shredded Mulch holds moisture in beds and tree rings through the summer.

Decorative options include 3/8" Natural Pea Gravel for walkways and play areas, River Gravel for beds and borders, and RipRap for bank protection and culvert outlets.

Ground and Conditions in Palos Hills

Across the Chicago lake plain and the northeastern moraines, the ground is heavy silt and clay over clay-rich till. That ground sheds water rather than takes it, and flat lots have little fall to work with.

Heavy summer downpours overwhelm yard grades and storm sewers in the older built-up areas. Water that cannot soak in has to go somewhere, and a graded surface with a drainage layer under it is how you move it away from a slab or a foundation.

Frozen ground stops compaction through the winter, so base and driveway work runs from the spring thaw into late fall. A wet spring keeps crews off soft clay until it drains.

Long cold winters with many freeze and thaw cycles lift drives, walks and slabs every spring. Gravel surfaces stay soft until the ground drains.

Northeastern Illinois jurisdictions carry a frost depth of about 42 inches in the residential code, and the local building department sets the figure for its own area.
