Lime Screenings for Patios in Hickory Hills, IL

Illinois Rock Supply handles gravel and aggregate delivery in Hickory Hills, IL, and the material this market builds on is CA-6, the dense graded crushed limestone with the fines left in. It goes under driveways, parking pads and shed bases.

Under pavers and flatwork, the layer that decides how the surface holds up is the bedding. That is lime screenings, and it is the standard bedding layer here.

Ground and Conditions in Hickory Hills

Across the Chicago lake plain and the northeastern moraines, the ground is heavy silt and clay over dense till. Water sheds off that clay instead of soaking in, and flat ground gives it little fall.

A thin base over clay shows the failure fast. The surface rocks, the joints open, and a walk or patio edge drops after a wet spring.

The fix is a base that carries the load and a bedding layer that drains and levels.

Frost is the other driver in this part of the state. Long winters with many freeze and thaw cycles lift drives, walks and slabs, and gravel surfaces stay soft until the ground drains.

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

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.

Materials for Hickory Hills Projects

Bedding under pavers and flatwork is where lime screenings do the work. The crushed limestone fines compact to a smooth, firm layer that lets you set pavers and flagstone true, and they backfill around pipe without the voids a clean stone leaves.

Below the bedding, CA-6 is the base course. It is dense graded crushed limestone with the fines left in, and it builds driveways, parking pads, shed and garage bases and trench backfill.

Chicago area yards also call this size grade 8 or grade 9, and downstate yards say CA-6.

Where water has to move, the clean washed stone takes over. CA-7 is 1 inch clean stone with no fines, for bedding under pipe, drainage trenches, French drains and concrete flatwork.

3/4" Crushed Stone, sold as CA-11, is the 3/4 inch clean washed stone Illinois yards sell alongside it.

For tighter work, CA-16 Chips are 3/8 inch limestone chips for permeable paver bedding, drainage around tanks and topping a compacted base. Lime Screenings remain the bedding layer for pavers and flagstone.

Concrete and mortar pull from the sands. Washed Sand, which Illinois yards call torpedo sand, is the coarse washed sand for concrete, leveling and bedding.

Mason Sand is the fine clean sand for brick and block mortar, paver joints, sandboxes and volleyball courts.
