CA-11 and Bulk Aggregates for St. Augustine, IL

Illinois Rock Supply handles gravel and aggregate delivery in St. Augustine, IL, by the ton or by the yard.

Start with the calculator on any product page to size the load, then pick your material. CA-6, the dense graded crushed limestone this market calls road base, is the base course for drives, pads and shed floors.

St. Augustine sits in Knox County, on ground that sheds water fast on slopes and holds it in the flats.

That split decides which stone a job needs.

Materials for St. Augustine Projects

Washed stone is where drainage work starts. Clean stone has no fines, so water moves through it instead of pooling, which is what a French drain, a drywell or a downspout run needs to function.

CA-7 is 1 inch clean washed stone. It beds pipe, fills drainage trenches and sits under concrete flatwork.

CA-11 is the 3/4 inch clean washed stone that Illinois yards sell alongside CA-7. It does the same bedding and drainage work at a smaller size.

3/4" Crushed Stone is a good fit for a downspout run that ends in a drywell.

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

CA-16 Chips work where the stone has to stay small.

For the base itself, CA-6 goes down as a compacted course under drives, parking pads and garage floors. Fill Dirt raises grade before that base goes down.

Lime screenings are the crushed limestone fines used to bed pavers and flagstone and to backfill around pipe. Torpedo sand is the coarse washed sand for concrete and leveling.

Mason sand is the finer clean sand for mortar and paver joints.

Delivery to St. Augustine and the Surrounding Area

You order online, choose a quantity by the ton or by the yard, and pick a delivery date at checkout. A dump truck then tips the load on site in one pile.

Coverage runs across St. Augustine and the rest of Knox County, including Galesburg, Abingdon, Knoxville, Wataga and Oneida.

If your site is inside that area, the truck reaches it.

Have the drop spot clear before the truck arrives. The load comes off the bed in a single pile, so the spot you choose is where the material stays.

Ground and Conditions in St. Augustine

Across the Western Illinois loess uplands and the Mississippi border, the working season runs from the spring thaw into late fall. That is a little longer than upstate, which gives you room to time a delivery around the ground rather than the calendar.

Deep loess over older drift behaves differently on slopes than on flats. On a slope it sheds water fast and cuts gullies; on a flat it holds water and stays soft.

A drainage layer of clean stone handles the wet ground. A compacted CA-6 base handles the load.

Frost still lifts drives and walks each spring in this part of the state. Frost depth figures belong to the local building department, which sets footing depth, so check with them before you plan anything structural.
