Bulk Aggregates for Patios in La Harpe, IL

If you are planning a patio, a shed pad, or a new driveway, gravel and aggregate delivery in La Harpe, IL starts with the base going in first. Illinois Rock Supply sells CA-6, the local name for dense graded crushed limestone with the fines left in.

It is the material that carries the load under pavers and flatwork. In this part of Hancock County, deep loess soil sheds water fast on slopes and holds it in the flats, so the base under a patio matters.

Ground and Conditions in La Harpe

Across the Western Illinois loess uplands and the Mississippi border, the ground is deep loess over older drift. On slopes that soil sheds water quickly, and in the flats it holds water and stays soft.

The failure shows up first in a thin base under pavers. Without enough compacted stone underneath, loess soil moves, pavers settle unevenly, and flatwork cracks along the edge.

The fix is a real base course of CA-6, built up and compacted before the bedding layer goes over it. CA-6 has the fines left in, so it knits together into a firm, stable surface that spreads the load.

Work here runs from the spring thaw into late fall, and frost lifts drives and walks each spring. Bottomland sites wait out spring high water.

Building departments set footing depth for structures; that is a separate question from your patio base.

Materials for La Harpe Projects

CA-6 is the backbone of most flatwork here. It is dense graded crushed limestone, the material Illinois yards sell for driveways, parking pads, shed and garage bases, and trench backfill.

Under pavers and flagstone, the bedding layer is usually lime screenings. Screenings are crushed limestone fines, and they give you a thin, level layer you can screed smooth before the pavers go down.

Larger projects need other sizes. CA-7 is washed 1 inch clean stone with no fines, used for drainage trenches, French drains, and bedding under pipe.

CA-11 is the 3/4 inch washed version, for drainage and concrete work.

CA-16 chips are the small 3/8 inch washed stone used for permeable paver bedding and drainage around tanks. Torpedo sand is the coarse washed sand for concrete and leveling, and mason sand is the fine clean sand for mortar, paver joints, and sandboxes.
