Bulk Material Delivery in Auburn, IL

Illinois Rock Supply brings gravel and aggregate delivery in Auburn, IL to driveways, pads and drainage work. CA-6, the dense graded crushed limestone with the fines left in, is the base material for this market.

This is flat Grand Prairie till plain ground with heavy clay under it, so water stands after a hard rain. Coarse stone that moves that water matters as much as the base itself.

Materials for Auburn Projects

Slope, swale and bank protection starts with the coarsest stone on the page. RipRap is heavy broken stone for bank protection, culvert outlets, pond edges and slope armoring.

RipRap holds a bank where runoff concentrates and a bare silt loam bank would gully.

Below that size, CA-7 is washed clean stone with no fines. It beds pipe, fills drainage trenches and French drains, and sits under concrete flatwork.

CA-7 passes water instead of holding it, which is the whole point in a trench.

CA-11 is the 3/4 inch clean washed stone sold alongside CA-7 for bedding, drainage and concrete work.

For a compacted base, CA-6 is the Illinois base material: dense graded crushed limestone with the fines left in. It goes under driveways, parking pads, shed and garage bases and trench backfill.

At the fine end, lime screenings are crushed limestone fines for paver and flagstone bedding and for backfill around pipe.

Lime Screenings are the standard bedding layer in Illinois. Torpedo sand is the coarse washed sand this state calls by that name, and it levels and beds.

Washed Sand mixes into concrete and sets a level bed under pavers. Where a drive already exists, Driveway Gravel surfaces it or tops a compacted base.

Ground and Conditions in Auburn

Base, driveway and paver work runs from the spring thaw into late fall. The ground is slow to dry in a wet spring and frozen solid through the winter.

Across the Grand Prairie till plain of central and eastern Illinois, the ground is flat with dense clay subsoil beneath it and almost no natural fall. Water stands rather than runs after heavy rain.

That is why a drainage layer earns its place here. Clean washed stone like CA-7 or CA-11 gives standing water somewhere to go instead of sitting against a slab or a foundation.

Erosion on this plain comes from sheet runoff off bare silt loam and from gullying where yard runoff concentrates. RipRap at an outlet or along a bank slows that water down before it cuts.

Cold winters bring repeated freeze and thaw, so frost heave shows up in gravel drives, walks and shallow slabs each spring. Frost depth is set by the local building department, and it is worth confirming before any footing work.

Questions About Stone and Delivery in Auburn

What stone should I use for drainage in Auburn?

Use clean washed stone with no fines.

Both pass water instead of holding it, which suits French drains, foundation drains and trench work. CA-16 chips work for tighter bedding and drainage around tanks.

What should I have ready when the truck arrives?

Have the drop spot clear, reachable and on firm ground before the truck gets there. The driver tips the load in one pile, so leave room for the pile itself and keep vehicles and equipment out of the way.

If the ground is soft from spring rain, pick a spot that will carry the weight.
