CA-7, Stone and Soil Delivery in St. Elmo, IL

Illinois Rock Supply handles gravel and aggregate delivery in St. Elmo, IL and the rest of Fayette County.

CA-6, the dense graded crushed limestone with the fines left in, is the base material most ground here gets built on. It goes under driveways, parking pads, shed floors and trench backfill.

Tight claypan subsoil sits close to the surface across this part of south central Illinois. Water perches on top of it and stays there for weeks.

That shapes what you put down and where the water goes.

Materials for St. Elmo Projects

Washed stone is the other half of the job. It has no fines, so water moves through it instead of sitting in it.

French drains, drywells and downspout runs are where it earns its place.

Start with the coarse end. CA-7 is 1 inch clean washed stone.

It beds pipe and fills drainage trenches. 3/4" Crushed Stone, sold as CA-11, does the same work at a smaller size and suits concrete flatwork.

Drain Rock covers French drains and foundation drains where the trench needs open stone the whole way.

CA-16 Chips are 3/8 inch chips for permeable paver bedding and drainage around tanks. Lime Screenings are the crushed limestone fines used to bed pavers and flagstone and to backfill around pipe.

For a drive or pad, CA-6 is the base. Driveway Gravel surfaces a drive or tops a compacted base.

RipRap is the heavy broken stone for bank protection, culvert outlets and pond edges.

Ground and Conditions in St. Elmo

The working season runs longer here than it does upstate, at both ends. A wet winter and spring still keep sites soft well into April.

Late summer and fall are the dependable windows for getting a load down and worked.

That timing matters because of the claypan. Loess sits over old, weathered Illinoian drift, and the tight subsoil underneath stops water moving down.

Rain perches on top of it and the ground stays saturated for weeks. Unbound base pumps under traffic when that happens, so a clean stone drainage layer under the base carries water away from it.

Thin loess bared of cover washes in sheets and gullies. Once the fines are gone from a drive, the surface ruts and the edges break down.

Clean stone in a downspout run or a drywell gives that water somewhere to go other than the drive.

Winters are cold but shorter than in the north, with freeze and thaw swings that work on saturated clay. That heaves drives and walks.

Building officials in this region set footing depth around 30 to 36 inches.
