Bulk Aggregates for Patios in Richton Park, IL

Illinois Rock Supply provides gravel and aggregate delivery in Richton Park, IL for patio bases, driveways and drainage work. If you are bedding pavers or pouring flatwork, the material under the slab is what holds the surface flat.

CA-6, the dense graded crushed limestone this market calls road base, is where most of that work starts.

Richton Park sits on clay-rich ground, and clay moves when it gets wet. The right base and bedding layers keep a patio from rocking out of level after a wet spring.

Ground and Conditions in Richton Park

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

A patio base laid on soft clay without a compacted course under it will shift and settle out of level.

The failure shows up as rocking pavers, low spots that hold water, and joints that open. The correction is a compacted CA-6 base course over the subgrade, with a clean bedding layer on top.

That base spreads the load and keeps the bedding from pumping into the clay below.

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

Plan the pour and the paver set for that window.

Northeastern Illinois jurisdictions carry a frost depth of about 42 inches in the residential code, and the local building department sets the figure that applies. Frost lifts drives, walks and slabs every spring and leaves gravel surfaces soft until the ground drains.

Materials for Richton Park Projects

Bedding is the layer that decides whether a patio stays flat. Lime screenings, the crushed limestone fines this market also calls screenings, are the standard bedding layer under pavers and flagstone in Illinois.

They compact to a firm, level surface that holds a paver without letting it rock.

Under that bedding goes the base. CA-6 is dense graded crushed limestone with the fines left in, and it compacts into a stable base for patios, driveways, parking pads and shed floors.

CA-6 is the material to build the base course from.

Where water has to move, use clean washed stone instead of a fines-bearing material. CA-7 is washed clean stone with no fines, for bedding under pipe, drainage trenches and French drains.

3/4" Crushed Stone, sold locally as CA-11, is the 3/4 inch clean washed stone for the same bedding and drainage work around flatwork.

For the tightest bedding, CA-16 Chips are 3/8 inch limestone chips for permeable paver bedding and for topping a compacted base. Washed Sand, which Illinois yards call torpedo sand, is coarse washed sand for concrete, leveling and bedding.

Around the patio, Top Soil handles lawns, grading and bed prep, and Shredded Mulch holds moisture in beds and tree rings through a summer.
