Lime Screenings for Patios in Crestwood, IL

Illinois Rock Supply handles gravel and aggregate delivery in Crestwood, IL, and the season shapes every load. 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.

CA-6, also called road base, is the dense graded crushed limestone with the fines left in. It builds the base under a patio, and lime screenings bed the pavers on top.

Ground and Conditions in Crestwood

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

A thin base over that clay shows its failure fast. Water sits in the subgrade, the base pumps and shifts, and the pavers above rock and dip at the joints.

The fix is a base that holds its shape and a bedding layer that stays level. CA-6 compacts into a firm, tight surface because the fines bind the crushed stone together.

It gives a patio or a slab a base that carries weight without moving.

Frost is the other driver here. Northeastern Illinois jurisdictions carry a frost depth of about 42 inches in the residential code, and the local building department sets the figure.

Many freeze and thaw cycles lift drives, walks and slabs every spring, and gravel surfaces stay soft until the ground drains.

Materials for Crestwood Projects

Bedding under pavers and flatwork is where the surface is won or lost. Lime screenings, also called limestone screenings, are the crushed limestone fines that level a paver or flagstone bed.

They pack tight, hold a consistent plane, and take the small adjustments that keep a patio flat.

Below the bedding, CA-6 carries the load. It is the Illinois base material for driveways, parking pads, shed and garage bases and trench backfill.

Clean washed stone handles the water. CA-7, also called #57 stone or 1 inch clean stone, is washed stone with no fines for bedding under pipe, drainage trenches and French drains.

CA-11, the 3/4 inch clean stone, does the same work at a smaller size.

CA-16 chips, the 3/8 inch limestone chips, bed permeable pavers and top a compacted base. Torpedo sand, the coarse washed sand Illinois yards sell, levels and beds, and mason sand goes into mortar and paver joints.

For a walk or a garden path, walkway gravel gives a finer, walkable surface. Rounded stone such as 3/8" Natural Pea Gravel suits play areas and fence post mix, and River Gravel works in beds, borders and dry creek beds.

Soil and mulch finish the job. Top Soil grades lawns and beds, and Shredded Mulch holds moisture in beds and tree rings through an Illinois summer.
