Lime Screenings for Patios in Downers Grove, IL

Gravel and aggregate delivery in Downers Grove, IL runs from the spring thaw into late fall. Frozen ground stops compaction through the winter, and a wet spring keeps crews off soft clay.

Illinois Rock Supply delivers CA-6, stone, sand and soil to DuPage County jobs by the ton.

Downers Grove sits on the clay-rich till of the northeastern moraines. That ground sheds water rather than takes it, so patios and flatwork here depend on what sits under them.

Ground and Conditions in Downers Grove

Clay till and flat ground leave water nowhere to go. Heavy summer rain sits on a yard grade instead of soaking in, and a thin base layer shows it first.

When the base under a patio is too thin, the slab or the pavers rock at the edges. Water reaches the clay, the clay holds it, and freeze and thaw cycles lift the surface every spring.

The fix is a base that drains and a bedding layer that stays put. Clean washed stone under the slab gives water a path out, and lime screenings on top give the pavers a level, workable bed.

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

Plan patio and flatwork work around the working season, not against it.

Materials for Downers Grove Projects

Bedding is what makes a patio last here. The layers under the surface do the work, and each one has a job.

Lime Screenings are the standard bedding layer in Illinois, and the local name for screenings. Crushed limestone fines pack into a firm, level bed under pavers and flagstone, and they backfill around pipe.

Screened fines hold their shape once they are worked in.

CA-7 is washed clean stone with no fines. It beds pipe, fills drainage trenches and French drains, and sits under concrete flatwork where water needs to move.

Illinois yards also sell 3/4" Crushed Stone, or CA-11, for the same bedding and drainage work.

CA-16 Chips are 3/8 inch limestone chips. They bed permeable pavers, drain around tanks, and top a compacted base.

For the coarser end, #4 Crushed Stone handles trench bottoms and heavy drainage.

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

Chicago area yards also call it grade 8 or road mix.

Sand and soil finish the job. Washed Sand, or torpedo sand, is the coarse washed sand for concrete and leveling.

Top Soil covers lawns and bed prep once the hard work is done.
